1. Advancing Nitrogen and Irrigation Management for Row Crops and Biofuel Crops in the Western USNitrogen, irrigation and N by irrigation studies from West Texas and central Arizona are discussed. In the first study with surface drip, deficit irrigation, N fertilizer rate response was observed with cotton (Gossypium hirsutum L.) in 50 and 75 % ET replacement, but not with dryland or 25 % ET. Irrigation level response was evident with LEPA in two of three years in Lamesa Texas, but not in a wet, third year. Variable-rate N showed a more consistent response than blanket-rate N in that...

2. Nitrogen Management and Budgets for Irrigated Cotton in the Western USAWe present research on new and improved and updated N fertilizer management recommendations for 4-bale/acre cotton based on a 36-inch NO3-N soil test for irrigated cotton from a 2-year study on surface/furrow irrigation study and a 1-year study under sprinkler irrigation. We also compared UAN with UAN plus the N loss inhibitor Agrotain Plus. Additionally, we compared reflectance- based N fertilizer management with soil test-based management. Nitrogen balances indicated that residual soil NO3 was... K. Bronson, J. Mon, E. Bautista, D. Hunsaker |
