Other claims from this paper (17)
- Association Optimum practices depended on genotype and planting date.
- Observation Optimal seeding rate for Seco was 40 to 60 lbs /A.
- Observation Optimal seeding rate for 2 -22 -9 was 80 lbs /A.
- Intervention effect Higher seeding rate decreased kernel weight and number per head.
- Intervention effect Higher seeding rate increased head number.
- Intervention effect Nitrogen gave no positive response except Seco planted December 23.
- Intervention effect Kernel weight was not influenced by N or P fertilizer.
- Association Kernel number per head increased for certain genotype and date combinations.
- Intervention effect Head number decreased with N rate.
- Intervention effect Head number increased with phosphorus.
- Observation Optimal row spacing was 18 inches at November 19 planting.
- Observation Optimal row spacing was 12 inches for Seco at January 22 planting.
- Intervention effect Other genotype and date combinations showed no yield differences from spacing.
- Intervention effect Kernel weight increased with row spacing at November 19 planting.
- Intervention effect Kernel number per head was generally not affected.
- Intervention effect Head number decreased with row spacing.
- Recommendation Authors caution that management recommendations are gross approximations.
