Germination & Emergence
7-10 daysSeedling emerges 7-10 days after planting; coleoptile breaks through soil, first true leaf appears
Ensure consistent soil moisture and warm temperatures (60°F minimum, optimal 65-85°F). Monitor for seedcorn maggots or wireworms. Good seed-to-soil contact is critical.
Vegetative Growth (V2-V8)
3-4 weeksRapid leaf expansion and nodal root development; plant establishes root system with 2-8 visible leaves
Apply pre-emergent herbicides if needed. Begin nitrogen applications. Monitor for early pests (flea beetles, army worms). Ensure adequate water and nutrients. This is the critical period for plant establishment.
Canopy Development & Tassel Formation (V8-VT)
4-5 weeksActive vegetative growth; plant grows 2-3 inches daily at peak; ear shoot initiation occurs; tassel emerges at leaf tip
Apply remaining nitrogen (split applications recommended). Monitor for spider mites, corn borers, and rust diseases. Ensure consistent moisture; drought stress now significantly impacts yield potential. This is the critical 2-week window before pollination.
Flowering & Pollination (VT-R2)
2-3 weeksTassel sheds pollen; silks emerge and elongate; pollination occurs; early kernel development begins (blister to dough stage)
Critical water period—maintain 1-1.5 inches per week. Avoid water stress or excessive nitrogen now. Monitor for corn earworm, disease pressure (rust, leaf blights). Minimize field operations that damage plants.
Grain Development & Maturity (R2-R6)
4-6 weeksKernels fill with starch and dry down; plant transitions from milk stage (R3) through dough (R4) and dent (R5) to physiological maturity (R6) with black layer formation
Reduce irrigation as kernels dent and harden. Monitor grain moisture (target 15-20% for harvest). Watch for late-season diseases (gray leaf spot, anthracnose) and late-feeding insects (corn borers). Cease irrigation once physiological maturity reached.

Common Pests
-
Bt (Bacillus thuringiensis) corn varieties, insecticidal sprays if threshold exceeded (>50% plants with egg clusters), field sanitation of crop residue, crop rotation
-
Bt corn hybrids, insecticide sprays at silk stage if population threshold met, monitoring for moth catches, pheromone traps
-
Crop rotation (essential), Bt rootworm corn hybrids, soil insecticides at planting, adult beetle management with foliar sprays if needed
-
Foliar insecticide applications, Bt products, monitoring for larvae, cultural practices (remove weeds, destroy crop residue)
-
Miticide sprays, irrigation to maintain plant vigor, predatory mites, avoid over-application of nitrogen
-
Insecticidal soaps, neem oil, predatory insects (ladybugs, lacewings), monitor population thresholds
-
Fungicide applications (especially if hybrid susceptible), resistant hybrid selection, crop rotation, residue management, adequate irrigation
-
Resistant variety selection (P1563AM has moderate resistance), fungicide sprays if severe, remove volunteer corn
-
Resistant hybrid use, fungicide applications, crop rotation, removal of infected plant tissue, avoid overhead irrigation
Uses
Livestock Feed & Animal Nutrition
CulinaryP1563AM grain is a primary ingredient in livestock feed formulations for cattle, swine, and poultry, providing energy from starch and essential amino acids. The dent corn phenotype is ideal for grinding into meal for balanced feed rations. [source]
Ethanol & Biofuel Production
HouseholdThis hybrid is widely used in ethanol production through fermentation of corn kernels and subsequent distillation, serving as a renewable fuel source and reducing dependence on fossil fuels. [source]
Food & Beverage Products
HouseholdDent corn kernels are processed into cornmeal, corn flour, corn oil, corn syrup, and refined carbohydrates used in baking, cereals, beverages, and processed food products. [source]
Industrial Starches & Chemicals
CraftCorn starch extracted from P1563AM kernels is used in manufacturing textiles, paper products, adhesives, biodegradable plastics, and various industrial chemicals. [source]
Wildlife & Bird Food
WildlifeWhole corn kernels and corn residue (stalks, cobs) provide food and habitat for waterfowl, upland birds, and wildlife, supporting ecosystem services and sustainable land management. [source]
Harvest Tips
Harvest when kernel moisture reaches 15-20% for safe grain storage (typically 120-130 days after planting, mid-October to early November in Midwest). For fresh/sweet corn use, harvest at milk stage when silks have dried but kernels still have high moisture. For grain, allow kernels to fully mature with black layer formation at the kernel base. Use combine harvester for grain; strip picker if only ears needed. Store in cool, dry conditions to maintain germination and prevent mold.
Fun Facts
- 🌱 Pioneer P1563AM is a medium-maturity hybrid (RM 113) that bridges the gap between early and late corn, making it adaptable to variable growing seasons across the upper Midwest corn belt.
- 🌱 Dent corn (Zea mays indentata) gets its name from the characteristic dent or indentation that forms at the top of the kernel as it dries, caused by the soft starch inside shrinking faster than the hard starch outside.
- 🌱 Modern hybrid corn like P1563AM can yield 150+ bushels per acre under optimal conditions (approximately 9,400+ pounds of grain per acre), compared to just 20-30 bushels per acre for open-pollinated landraces grown a century ago.
