Germination & Emergence (VE)
7-14 daysSeed absorbs water and radicle emerges; first leaf appears above soil surface after 7-10 days depending on soil temperature and moisture
Soil temperature should be minimum 50°F, optimal 60-86°F. Ensure adequate soil moisture. Protect emerging seedlings from crusting soils. Monitor for seed-treatment efficacy against soil pathogens
Vegetative Growth (V2-V6)
4-6 weeksVisible leaves expand from the whorl; plant establishes root system and reaches 6-12 inches tall. Multiple root layers developing
Critical period for establishing adequate plant population. Control early-season weeds to reduce competition. Begin monitoring for insect pests (armyworms, cutworms). Nitrogen is being actively accumulated. Sidedress nitrogen if basal application was insufficient
Rapid Growth & Development (V7-VT)
4-6 weeksPlant grows 2-4 inches per day; 10-12 leaves visible; tassel visible in whorl; plant reaches 3-6 feet tall. Extensive root development
Monitor moisture carefully—this is when 50% of water is typically used. Watch for disease (gray leaf spot, northern corn leaf blight). Scout for spider mites in dry conditions. Avoid mechanical damage (cultivation). Ensure adequate potassium for stalk strength
Flowering & Pollination (R1-R3)
2-3 weeksTassel emerges and sheds pollen; silks emerge from ear husks; visible ear formation. Plant at full height (6-8 feet typical for P1335AM)
This is the most critical stage for yield. Water stress here directly reduces kernel set—maintain 1-1.5 inches per week. Pest and disease pressure peaks; scout frequently. Avoid any stress (physical damage, extreme temperatures). Ensure pollination occurs under good conditions
Grain Development & Maturity (R4-R6)
5-8 weeksKernels fill with starch and dry down; milk stage becomes dough stage then hard dent stage; plant senescence begins; moisture declines from 30% to 15-20%
Reduce water input as grain fill completes (R5-R6). Allow natural field drying rather than irrigating at R5+. Monitor for late-season pests and diseases. Grain is ready for harvest when moisture reaches 20-25% for combine harvesting (further drying may be needed for storage)

Common Pests
-
Bt corn hybrids, insecticide applications at whorl stage (V4-V6), crop rotation, field sanitation (remove infested stubble)
-
Crop rotation (at least 2 years away from corn), Bt rootworm corn, insecticide seed treatments, adult management sprays if threshold exceeded
-
Insecticide applications when larvae appear, Bt corn hybrids, field scouting, removal of infested plant parts
-
Silicide insecticides applied at silk emergence, resistant hybrids, beneficial insect conservation
-
Usually minor; insecticides only if populations exceed economic threshold; parasitoid wasps provide natural control
-
Irrigation during dry spells to reduce stress, miticide applications if severe, predatory mites
-
Fungicide applications if disease pressure high, resistant hybrids, crop rotation, removal of infected residue
-
Fungicide sprays at V8-VT and R1, resistant hybrids, crop rotation, field sanitation
Uses
Animal feed and grain production
CulinaryP1335AM is a dent corn hybrid primarily used for livestock feed, ethanol production, and industrial uses rather than fresh eating. The grain is ground for animal feed or processed into various food ingredients. [source]
Ethanol and biofuel production
CulinaryField corn hybrids like P1335AM are major feedstocks for ethanol fuel production through fermentation of the starchy grain. This renewable fuel application is a significant market for modern corn hybrids. [source]
Industrial corn products
HouseholdThe grain is processed into corn meal, corn flour, cornstarch, corn oil, and numerous industrial products including biodegradable plastics and chemicals. [source]
Wildlife food source
WildlifeCorn grain remaining in fields after harvest provides valuable fall and winter food for migratory waterfowl, deer, and other wildlife. Conservation-minded farmers often leave grain for wildlife benefit. [source]
Corn silk and nutritional value
MedicinalWhile P1335AM is field corn, corn silk has traditional medicinal uses for urinary health. The grain itself is nutrient-dense with vitamins, minerals, and antioxidants. [source]

Harvest Tips
Harvest when grain moisture reaches 15-25% depending on storage and drying infrastructure. Combine when moisture is 20-25% to minimize field losses and grain damage. For grain storage, dry to 13-15% moisture to prevent mold and allow long-term storage. Yield is typically 120-160 bu/acre under good management in favorable conditions. Harvest timing is flexible with this hybrid—grain flows well from combines. Store grain in dry conditions at proper moisture to prevent aflatoxin development.
Fun Facts
- 🌱 P1335AM was designed with good disease resistance, particularly against common fungal diseases in humid growing regions, making it reliable across diverse environments.
- 🌱 Modern corn hybrids like P1335AM produce ears with 500-1000+ kernels, with each kernel containing starch, oil, and protein—remarkable yields from a single plant.
- 🌱 Corn is an "indeterminate" determiner in that it can produce multiple ears per plant (typically 1-2 primary ears), though P1335AM is bred for consistent single-ear dominance for grain quality.
