What to Plant First in Spring to Get Ahead of the Season in Nebraska

Why Your First Spring Planting Decisions Determine Your Whole Year’s Success

Every Nebraska producer knows the feeling. Mid-March arrives with that first stretch of 50-degree days, soil starts to work, and suddenly you’re facing a compressed window where every decision matters. Plant too early and a late freeze sets you back. Wait too long and you miss the moisture. Rush everything in at once and you’ll watch half your investment struggle.

The truth is, spring planting success in Nebraska isn’t about working harder during those few critical weeks. It’s about working smarter with a strategic sequence that matches each crop to its ideal conditions. When you plant the right crops at the right time, you capture spring moisture, outcompete weeds before they establish, and create early grazing opportunities that reduce your hay costs by hundreds of dollars per head.

This guide breaks down exactly what Nebraska producers need to plant first, what can wait, and how to avoid the costly mistakes that turn a promising spring into a scramble by June.

Section 1: Why Early Spring Planting Sets the Tone for Your Entire Grazing Season

Capturing Nebraska’s Most Valuable Resource: Spring Moisture

Between late March and mid-May, Nebraska receives some of its most reliable precipitation of the year. For eastern Nebraska, this typically means 3-4 inches during April alone. This spring moisture window is your most valuable planting asset because the soil is already near field capacity from snowmelt, and temperatures are ideal for cool-season forage establishment.

When you plant cool-season forages early—late March through mid-April—their root systems develop during this moisture-rich period. A well-established alfalfa seedling or oat plant in April has 2-3 months of root development before summer heat and drought stress arrive. Plant those same crops in late May, and you’re asking them to establish during the stress period rather than before it.

According to University of Nebraska-Lincoln Extension research, fertilized smooth bromegrass in eastern Nebraska shows a 30% yield increase when nitrogen is applied in late March through April compared to later applications. Why? Because the moisture is there to activate it, and the plant is primed for rapid spring growth.

Winning the Weed Competition Before It Starts

Here’s something most producers learn the hard way: the weeds you control in April determine your weed pressure in July. Cool-season weeds like cheatgrass, downy brome, and broadleaf weeds germinate early and grow aggressively while your pastures are still dormant. By the time your perennial grasses green up in May, these weeds have already claimed moisture, nutrients, and light.

Early-planted cool-season annuals change this equation completely. When you drill oats or plant cereal rye in late March to early April, you’re establishing a competitive crop before weeds can dominate. A thick stand of oats at 6-8 inches by early May shades out emerging broadleaf weeds and competes aggressively for the same resources cheatgrass needs.

For alfalfa fields, spring weed control is absolutely critical. Nebraska Extension specialists emphasize that herbicide effectiveness depends on treating weeds when they’re less than four inches tall. If you’re planting new alfalfa stands or managing thin established fields, your March and April weed control decisions directly impact whether you have a productive stand or a weed-choked disappointment by first cutting.

Creating Early Grazing Opportunities That Save Money

Let’s talk dollars and cents. Feeding hay through April and May costs Nebraska producers approximately $2.50-$3.50 per head per day, depending on hay prices and quality. If you can move 100 head of cattle onto early spring grazing two weeks earlier, you’re looking at $3,500-$4,900 in saved hay costs.

Cool-season annuals planted in late March provide exactly this opportunity. Winter cereals like cereal rye, winter wheat, or triticale that were planted last fall can start being grazed in April once plants reach 5-6 inches. Spring-planted oats come on strong by the third week of May, often reaching 6-8 inches and ready for first grazing just when your hay bill is at its peak.

This early grazing also gives your perennial pastures additional recovery time. Instead of turning out onto smooth brome or native range in late April when plants are just beginning growth, you graze your annuals first. This means your primary summer pastures get an extra 3-4 weeks of uninterrupted growth, building root reserves and establishing robust stands before grazing pressure begins.

Setting Up Sequential Forage Availability

Think of spring planting as setting up a relay race, not a sprint. The crops you plant in late March provide forage in May. The crops you plant in mid-April provide forage in June. The crops you plant in late May provide forage in July and August. This sequential approach creates a continuous forage supply rather than feast-or-famine cycles.

Early cool-season establishment is the first leg of this relay. When your cereal rye is being grazed in April and your spring oats hit peak production in late May, you’ve created space to plant warm-season annuals in mid to late May. Those sudangrass or sorghum-sudan plantings then provide high-quality grazing in July and August when cool-season productivity declines.

Without that early spring foundation, producers often find themselves scrambling in June with inadequate forage and few good planting options remaining. The window for warm-season annual establishment closes by early June in much of Nebraska, and if you’re still trying to establish cool-season crops that should have been planted in March, you’ve missed the optimal window for both.

Section 2: Cool-Season Forages That Demand Early Planting in Nebraska

Spring-Planted Oats: Your Most Versatile Early Spring Option

Optimal Planting Window: Late March to mid-April Expected Grazing Start: Mid to late May (when plants reach 6-8 inches) Why Plant First: Oats are the champion of early spring forage in Nebraska. They germinate in cool soil (as low as 38°F), grow rapidly during Nebraska’s unpredictable spring weather, and produce high-quality forage when feed costs are highest.

Spring-planted oats offer unique advantages for Nebraska operations. Unlike winter cereals that require fall planting, oats can go in the ground as soon as soil is workable in late March or early April. They grow during the spring moisture window and use moisture very efficiently to produce forage. A well-managed oat pasture can support one cow-calf pair per 2 acres in early spring, gradually increasing as growth accelerates.

The key to successful oat grazing is starting early and grazing frequently. Once oats reach 6-8 inches (typically third week of May in eastern Nebraska), begin grazing to stimulate tillering and encourage the plant to produce more stems. If you let oats get 12+ inches before first grazing, they won’t stool out and regrow effectively. Keep managed height between 6-16 inches for continuous regrowth.

For extended grazing, mix oats with Italian ryegrass at planting. Oats provide strong early growth, while Italian ryegrass takes over in June, extending your cool-season grazing window well into summer.

Planting Specifications:

Seeding rate: 2-3 bushels per acre (80-100 lbs/acre)
Seeding depth: 1-1.5 inches
Fertilization: 40-60 lbs N per acre unless following heavily fertilized crop

Alfalfa: The Foundation That Requires Perfect Timing

Optimal Planting Window: April 1-May 15 (eastern/southern NE); April 15-May 15 (western/northern NE) First Harvest: 60-70 days after planting Why Plant Early: Alfalfa is the cornerstone of most Nebraska forage programs, but successful establishment requires hitting the right window. Too early and late frosts damage seedlings. Too late and summer heat stresses young plants before they’re established.

Nebraska Extension research shows that alfalfa seeded in April benefits from spring moisture and cooler temperatures that allow strong root development before summer heat arrives. The plant needs 2-4 trifoliate leaves before it can withstand stress, and early planting gives it time to reach this stage while moisture and temperatures are favorable.

Soil temperature is your guide. Alfalfa germinates best when soil temperature reaches 50°F at 2-inch depth. In eastern Nebraska, this typically occurs in early to mid-April. Check soil temperature for three consecutive days—if you’re consistently at 50°F or above, conditions are right for planting.

Critical establishment factors for Nebraska:

Soil pH: 6.5-7.5 (optimum 6.8) – Test and lime if needed the previous fall
Seeding depth: ¼-½ inch in fine-textured soils; ¾ inch in sandy soils
Weed control: Critical during establishment – young alfalfa can’t compete with weeds
Variety selection: Winter survival rating of 3 or lower for Nebraska; fall dormancy rating 1-5

For herbicide-tolerant varieties, plan your weed control strategy before planting. Roundup Ready alfalfa allows glyphosate application between emergence and fourth trifoliate stage, giving you excellent weed control options during establishment. Conventional varieties require more timing precision with selective herbicides.

Smooth Bromegrass Fertilization: Not Planting, But Critical Early Spring Work

Optimal Application Window: Late March through April Why This Window Matters: While you’re not planting new brome, fertilizing your established smooth bromegrass pastures in late March to April is one of your highest-return spring investments. The nitrogen application should happen early enough that spring moisture activates it and the plant is in active growth phase.

Eastern Nebraska smooth brome responds dramatically to 80-100 lbs actual N per acre in a single spring application. This recommendation decreases westward—western Nebraska typically uses 30-40 lbs N per acre due to lower moisture. Research shows a 30% yield increase with proper spring fertilization.

If you’re doing split applications, apply two-thirds in spring and one-third when fall growth resumes. Spring moisture is critical for nitrogen uptake, so monitor soil moisture. In drought years, that fertilizer application won’t show its full potential without adequate precipitation.

Cereal Rye, Winter Wheat, and Triticale: The Fall-Planted Early Grazers

Planting Window: Previous fall (September-October) Spring Grazing Start: April, when plants reach 5-6 inches Why They Matter for Spring Strategy: While these winter cereal crops were planted last fall, they’re your earliest spring forage source and deserve strategic management starting in March.

Winter cereals green up early in Nebraska, often providing grazing opportunities 3-4 weeks before spring-planted oats. Grazing typically begins in April when plants reach 5-6 inches. Manage height between 5-10 inches for optimal regrowth and quality.

These crops are extremely high in quality during early spring grazing—crude protein often exceeds 20%, and digestibility is excellent. However, they’re also high in potassium, which interferes with magnesium absorption. Provide free-choice mineral supplementation with targeted 4 oz per head per day magnesium intake to prevent grass tetany.

Common mistakes with winter cereal grazing:

Letting grass get ahead of the cattle: The most common error. As spring progresses, growth accelerates dramatically. If grass gets to 12+ inches, quality drops and cattle can’t keep up with growth. Increase stocking density or reduce grazed acres to maintain control.
Not managing for regrowth: Rotational grazing with shorter grazing periods (3-5 days) and adequate recovery (14-21 days) maintains plant vigor and extends the grazing window.
Ignoring the transition to warm-season pastures: Plan to move cattle off winter cereals and onto warm-season annuals or summer pastures before cereals reach reproductive stages in June.

Section 3: What Can Wait—Warm-Season Crops and Strategic Patience

Understanding Soil Temperature Requirements for Warm-Season Success

The biggest mistake Nebraska producers make in spring isn’t planting too early—it’s planting warm-season forages before soil conditions are right. Warm-season annuals like sudangrass, sorghum-sudan hybrids, pearl millet, and foxtail millet require soil temperatures of 60-65°F at 2-inch depth for reliable germination. In most of Nebraska, this doesn’t occur until mid to late May.

Planting warm-season annuals in late April or early May when cool-season crops should go in leads to:

Poor, uneven germination
Weak seedling vigor
Increased disease pressure from cold, wet soil
Extended vulnerability to late spring weeds
Delayed establishment that pushes first grazing into mid-July

Patience pays here. A sudangrass planting on May 20 when soil temperature is 65°F will germinate in 5-7 days, establish vigorously, and be ready for first grazing in late June or early July. That same planting on May 1 when soil temperature is 55°F might take 14-18 days to germinate, emerge unevenly, and face heavy weed pressure before developing a canopy.

Warm-Season Annual Forages: Ideal Planting Timeline

These warm-season annuals create the second wave of your sequential forage program. While your cool-season crops (planted in March and April) are providing May and June grazing, you’re planting warm-season annuals in mid to late May. This timing allows:

Full utilization of early spring for cool-season establishment rather than compromising both crop types
Optimal germination and vigor for warm-season species
Sequential forage availability through July and August
Double-cropping opportunities on irrigated or high-moisture ground

Double-Cropping Strategies for Maximum Forage Production

For producers with irrigation or reliable summer rainfall, double-cropping cool-season and warm-season annuals maximizes forage production per acre. The strategy works like this:

Spring Cool-Season Crop (planted late March):

Oats, winter wheat, or triticale
Grazed April-May or hayed in late May/early June
Removed by mid-June

Summer Warm-Season Crop (planted mid-May to early June):

Sudangrass or pearl millet for grazing
Forage sorghum for hay/silage
Provides forage July-September

The key is timely operations. If you’re haying your cool-season crop, schedule equipment and labor to remove hay quickly in late May or early June. Plant warm-season crop immediately after harvest. Any delay reduces the warm-season crop’s growing window.

For grazing, consider flash grazing the cool-season crop in late May to prepare for warm-season planting. High-intensity, short-duration grazing can remove significant forage while leaving enough residue to protect soil. Terminate with light tillage or herbicide if needed, then plant warm-season crop.

Nebraska Extension research shows successful double-cropping requires adequate moisture—either irrigation or timely rainfall. In dryland situations, moisture is often limited enough that single-cropping provides better results than stressed double-crops.

Why Patience With Warm-Season Planting Protects Your Investment

Consider the economics. Sudangrass seed costs $25-40 per acre. Fuel, equipment wear, and labor add another $20-30 per acre. You’re investing $45-70 per acre minimum. If you plant three weeks too early in soil that’s 55°F instead of 65°F, you’re risking:

40-60% reduction in stand establishment
2-3 week delay in first grazing (negating any perceived advantage from early planting)
Increased herbicide costs for weed control during extended emergence
Potential need to replant, doubling your input costs

Conversely, waiting for right soil temperature costs you nothing and delivers:

90%+ germination rates
Vigorous, uniform stands
Reduced weed pressure from rapid canopy development
First grazing on schedule or even earlier than poorly-timed early plantings
Maximum return on seed and establishment investment

Check soil temperature with a soil thermometer at 2-inch depth, first thing in the morning for three consecutive days. When you’re consistently at 60-65°F, it’s time to plant warm-season annuals. Not before.

Section 4: Common Early-Season Mistakes That Cost Nebraska Producers Money

Mistake #1: Planting Everything at Once When Soil Becomes Workable

The temptation is strong. Soil dries out enough to work in late March, temperatures hit 60°F for three days straight, and every producer instinct says “plant everything now.” This approach typically leads to:

Cool-season crops planted too late: If you’re planting oats in mid-May because you spent late March and April trying to get warm-season annuals established, you’ve missed the optimal cool-season window. Oats planted after May 1 in eastern Nebraska face increasing heat stress and declining moisture.

Warm-season crops planted too early: Sudangrass planted in early April sits in cold soil for 2-3 weeks, emerges poorly, and struggles to establish. You’ve tied up acres in a failing crop when those acres could have been productive with properly-timed cool-season forages.

Sequential forage gaps: When everything goes in at once, everything matures at once. You get a flush of forage in mid-June, then a gap in late July when both cool and warm-season crops are past prime. Strategic sequencing spreads forage availability across the entire grazing season.

The solution: Create a planting calendar in January or February that sequences crops by optimal timing. Commit to this schedule regardless of spring weather’s false starts and stops.

Sample Nebraska Spring Planting Sequence (Eastern Nebraska):

Late March: Spring oats, oats/Italian ryegrass mixes
Early to mid-April: Alfalfa, spring-seeded legumes
Late March-April: Smooth brome fertilization
Mid to late May: Sudangrass, sorghum-sudan, pearl millet
Late May to early June: Double-crop warm-season annuals after removing cool-season hay

Mistake #2: Ignoring Soil Readiness—Temperature, Moisture, and Structure

Soil Temperature Matters More Than Air Temperature

Air temperature might hit 70°F in late March, but if soil temperature at planting depth is still 45°F, you’re not ready to plant. Each crop has specific soil temperature requirements for germination:

Cool-season forages (oats, cereals): 38-45°F
Alfalfa: 50°F
Warm-season annuals: 60-65°F

Invest in a soil thermometer ($15-25) and use it. Check temperature at planting depth (1-2 inches for most forages) first thing in the morning. Do this for three consecutive days. If temperatures are consistently at or above the crop’s minimum requirement, you’re ready. If not, wait.

Nebraska Resource: Check real-time soil temperatures across Nebraska via UNL CropWatch.

The “Snowball Test” for Soil Moisture

Soil that’s too wet is worse than soil that’s too cold. Wet soil compacts easily, creating conditions that damage soil structure for years. The damage you do driving equipment and drilling seed into wet soil in March can affect that field’s productivity through the entire growing season.

Use the snowball test: Grab a handful of soil and squeeze it into a ball. Then:

If it falls apart immediately when you poke it, soil is too dry
If it holds together but breaks apart cleanly when you poke it, moisture is right
If it stays in a ball and feels sticky or plastic, it’s too wet

Work wet soil and you create compaction layers, destroy soil aggregates, and reduce infiltration capacity. This means less moisture reaches plant roots even when rainfall is adequate.

Field Conditions Vary—Even Within the Same Farm

South-facing slopes dry out 5-10 days before north-facing slopes. Sandy soils are workable before clay soils. Fields with good drainage are ready before fields with poor drainage. Don’t treat your entire operation as a single unit.

Start with your best-drained, south-facing fields. Get those productive early. Your heavy soils and poorly drained areas can wait—and should wait until conditions are right. Planting sequences should account for field-level differences, not just crop differences.

Mistake #3: Underestimating Spring Weed Control in New Seedings

Here’s what commonly happens: Producer drills oats or alfalfa in early April, gets good germination, sees a nice stand emerging, and congratulates himself on a job well done. Two weeks later, weeds are outpacing the crop, stealing moisture and nutrients. By early May, what should be a thick stand of oats is a weedy mess.

For New Alfalfa Stands:

Alfalfa seedlings are terrible weed competitors for the first 60 days. Your weed control strategy must begin before planting:

Pre-plant: If the field has herbicide-resistant weeds, light tillage or glyphosate application before planting creates a clean seedbed
At-planting: Partner/Prowl can provide residual weed control during emergence
Post-emergence: Wait until alfalfa has 2-4 trifoliate leaves, then apply labeled herbicides for broadleaf and grass control
Critical timing: Weeds must be treated before they reach 4 inches—after that, herbicide effectiveness drops dramatically

For Roundup Ready alfalfa varieties, your flexibility increases. You can apply glyphosate between emergence and fourth trifoliate stage, eliminating most emerged weeds. This is why many Nebraska producers prefer herbicide-tolerant varieties for new seedings.

Resources:

UNL NebGuide G2247: Seeding Alfalfa – Complete establishment guidelines

For Spring Oats and Other Annuals:

Oats grow fast enough to outcompete most weeds IF they establish a thick, uniform stand. But thin spots invite weed pressure. Your defense:

Adequate seeding rate: 80-100 lbs/acre (2-3 bushels) ensures thick stands
Proper seeding depth: 1-1.5 inches deep—shallow enough for rapid emergence, deep enough for moisture
Early grazing management: Start grazing at 6-8 inches to encourage tillering and maintain competitive canopy

If broadleaf weeds become problematic in oat pastures, mowing when oats are 6-10 inches can set back weeds while oats regrow vigorously. This is preferable to herbicides in a grazing situation.

Mistake #4: Poor Variety Selection for Nebraska Conditions

Not all alfalfa varieties survive Nebraska winters. Not all oat varieties perform well in spring planting. Choosing varieties based on price alone or what was available at the co-op often leads to disappointment.

For Alfalfa:

Winter survival rating: 3 or lower (1 is most hardy) – Non-negotiable for Nebraska
Fall dormancy rating: 1-5 for Nebraska (lower = more dormant, better winter survival in traditional varieties)
Disease resistance: Look for resistance to bacterial wilt, Phytophthora root rot, and anthracnose
Intended use: Hay varieties vs. grazing varieties have different growth characteristics

For Oats:

Spring types: Ensure you’re buying spring oats, not fall oats
Disease resistance: Crown rust and barley yellow dwarf virus resistance important in Nebraska
Maturity: Earlier-maturing varieties work better for spring grazing programs

Don’t cheap out on seed. The difference between a $45/acre variety with poor winter survival and a $65/acre variety that lasts 5+ years is $4 per year. Penny wise, pound foolish.

Mistake #5: No Backup Plan for Weather Disruptions

Spring in Nebraska is predictable only in its unpredictability. Late April freezes, early May hailstorms, weeks of rain when you need dry conditions—all are normal here. Producers who commit 100% to one planting date or one crop strategy often find themselves scrambling.

Build flexibility into your spring plan:

Multiple Planting Windows:

Divide your oat acres into two plantings (late March and mid-April) rather than one
If first planting fails or weather prevents it, you still have options
If first planting succeeds, second planting extends grazing window

Alternative Crops:

If alfalfa window closes due to weather, switch to later-season options
If warm-season planting is delayed, earlier-maturing varieties salvage the season

Equipment and Labor Readiness:

Service equipment in winter, not during planting season
Line up custom operators early with flexible dates
Have seed sourced by early March, not scrambling in April

The producer who says “I plant oats April 1 no matter what” will occasionally have perfect timing. More often, he’ll have mediocre results. The producer who says “I plant oats between March 25 and April 15, depending on soil temperature and moisture” consistently gets better stands.

Wrap-Up: Smart Sequencing Beats Rushing Every Time

Success in Nebraska spring forage planting isn’t about being first or planting the most acres the fastest. It’s about matching each crop to its optimal conditions and creating a sequence that provides forage throughout the grazing season.

The producers who consistently have excellent stands, minimal weed pressure, and adequate forage from May through September follow these principles:

Plant cool-season crops early (late March to mid-April) when soil temperatures reach 40-50°F. These crops capture spring moisture, outcompete early weeds, and provide May-June forage that dramatically reduces hay feeding costs.

Be patient with warm-season crops (mid-May to early June) until soil temperature reaches 60-65°F. Rushing these plantings costs you money in poor stands and replanting. Waiting delivers vigorous establishment and productive July-August grazing.

Respect soil conditions more than calendar dates. Soil temperature and moisture determine success, not whether it’s April 1 or April 15. Invest in a soil thermometer, use the snowball test, and only plant when conditions are right.

Control weeds aggressively during establishment. The money you save by skipping herbicides on a new alfalfa seeding gets eaten up by reduced stands, lower yields, and shorter stand life.

Build flexibility into your plan. Have multiple planting windows, alternative crops, and equipment ready early. Nebraska spring weather will disrupt your plans—don’t let it derail your entire season.

Your spring planting sequence is an investment that pays dividends all season long. Get it right in March and April, and you’ll see the returns in lower feed costs, healthier cattle, better pasture conditions, and less stress during the summer grazing season.
