Long-Term Nitrogen, Phosphorus, And Potassium Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond
Long-Term Nitrogen, Phosphorus, And Potassium Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated grain sorghum in western Kansas. In 2019, N applied alone increased yields 66 bu/a, whereas N and P applied together increased yields up to 85 bu/a. Averaged across the past 10 years, N and P fertilization increased sorghum yields up to 78 bu/a. Application of 160 lb/a N (with P) produced the maximum yield in 2019, which is slightly more than the 10-year average. Application of potassium (K) has had no effect on sorghum yield throughout the study period. Average grain N …

Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, Alan J. Schlegel, H. Dewayne Bond
Kansas Agricultural Experiment Station Research Reports
Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated corn in western Kansas. In 2019, N applied alone increased yields by 71 bu/a, whereas P applied alone increased yields by 10 bu/a. Nitrogen and P applied together increased yields up to 131 bu/a, which is 10 bu/a less than the 10-year average of 141 bu/a. Application of 120 lb/a N (with highest P rate) produced 97% of maximum yield in 2019, which is slightly greater than the 10-year average. Application of 80 instead of 40 lb P2O5/a …
