NK0670 Corn Hybrid
Zea mays
vegetableNK0670 is a field corn hybrid developed by Monsanto (now Bayer), bred for grain production and silage use. This mid-maturity hybrid is designed for reliable yields in temperate climates and is commonly grown across North America for commercial feed, ethanol, and grain markets.

Germination & Emergence (VE)
7-14 daysSeed germinates and coleoptile emerges from soil; first true leaf visible within 7-10 days
Ensure consistent soil moisture; monitor for seed corn maggot and wireworm damage; soil temperature should be 50°F minimum
Vegetative Growth (V4-V12)
4-6 weeksPlant develops 4-12 visible leaves; roots establish deep root system; significant height gain occurs; tassel primordia form
Apply pre-emergence herbicides early; monitor for corn borer and armyworm; maintain adequate nitrogen; control weeds during V4-V8 critical period
Tasseling & Silking (VT-R1)
1-2 weeksTassel emerges; silks appear and elongate; pollen sheds; ear develops; peak plant height reached
This is the most critical period for water and nutrients; ensure 1-1.5 inches water weekly; avoid stress; monitor for spider mites and drought stress
Grain Development (R2-R5)
4-6 weeksKernels fill with starch and nutrients (milk stage R3 to dough stage R5); plant gradually senesces; leaf color changes
Continue adequate water through R4; monitor for late-season diseases; reduce nitrogen stress by this point; prepare for harvest logistics
Physiological Maturity & Harvest (R6)
2-4 weeks after R5Black layer forms at kernel base; moisture content drops to 20-25%; plant fully mature and ready for harvest
Allow moisture to dry to 15-20% for combining; harvest when field conditions allow; monitor for ear drop and stalk breakage in wind

Common Pests
-
Bt-transgenic varieties, insecticide applications at whorl stage (V4-V8), crop residue management and fall tillage
-
Bt-transgenic hybrids, crop rotation, soil insecticides at planting if history present, resistant rootworm hybrids
-
Scout at V4-V8; spray pyrethroids or other insecticides when threshold reached (>50% plants with damage)
-
Monitor silking period; Bt traits provide control; insecticide sprays if needed during R1-R3
-
Bt hybrids (Cry1A.105/Cry2Ab2 for FAW control); monitor whorl stage; early-season insecticide applications if needed
-
Monitor for large colonies during tasseling; insecticide spray if populations exceed 100 aphids/leaf; rarely economical to treat
Uses
Livestock Feed & Grain
CulinaryNK0670 grain is a primary feedstock for cattle, swine, and poultry operations, providing essential carbohydrates and energy. It is also processed for human food products including corn meal, corn oil, and corn starch. [source]
Ethanol & Biofuel Production
HouseholdA significant portion of NK0670 corn is processed into ethanol for fuel blending and industrial applications. This supports renewable energy markets and reduces petroleum dependence. [source]
Silage for Animal Agriculture
HouseholdWhen harvested at moisture content of 25-40%, NK0670 can be chopped and fermented as silage, providing a nutritious forage for dairy and beef cattle herds during winter months. [source]
Industrial Starch & Sweeteners
HouseholdCorn grain is processed to extract starch, which is used in food manufacturing, textiles, paper production, and fermentation industries. High-fructose corn syrup and corn syrup are derived from this starch. [source]
Wildlife Food Source
WildlifeCorn grain and field residue provide seasonal food for migratory waterfowl, deer, and other wildlife. Leaving some grain in the field supports wildlife habitat. [source]
Harvest Tips
Harvest when kernel moisture reaches 15-20% for mechanical combining; typically late September to October in northern regions. Cob moisture should be <30%. Monitor for ear drop in high winds; adjust combine settings for optimal kernel quality and minimal grain loss. If harvesting for feed/silage, earlier harvest (25-40% moisture) is preferred. Grain for storage/sale should be dried to 15% moisture or below.
Fun Facts
- 🌱 NK0670 is a Genetically Modified (GM) hybrid that typically contains Bt traits (Cry1Ab, Cry1F, or Cry1A.105/Cry2Ab2) for resistance to lepidopteran pests, reducing insecticide applications.
- 🌱 Field corn (dent corn) like NK0670 differs from sweet corn by having higher starch content and lower sugar; the kernels develop a characteristic 'dent' at the crown as they dry due to differential starch shrinkage.
- 🌱 Monsanto's NK brand represents 'Nucleodiversity Kernel,' emphasizing genetic diversity and stability in hybrid breeding; NK0670 was engineered for predictable performance across diverse growing regions.
