dc.description.abstractTwo phosphorus (P) fertilization studies were conducted for two field seasons to assess the effects of starter fertilizer on early corn plant growth, maturity, grain yield and grain moisture at harvest. A crop rotation study evaluated corn response to spring side banded P and Zn fertilizer when corn followed canola versus soybean. Side banded fertilizer increased early season biomass by up to 110% compared to the unfertilized control, with the largest increases in corn following canola. Silking date was advanced by 3-7 days with application of starter fertilizers. At harvest, all starter fertilizer treatments reduced grain moisture by 2-3% in corn following canola only, and there was a 10% yield increase in grain yield with the high rate of MAP compared to the control, regardless of preceding crop. Second, a residue management study evaluated corn response to fall banded and spring side banded P fertilizer in strip-tillage and conventional tillage. At two site-years, spring side banded P treatments increased early season biomass by up to 103% compared to the unfertilized controls. Banded P treatments reduced days to silking by 2-3 d compared to the unfertilized control. Spring side band P treatments increased grain yield by an average of 467 kg ha-1 relative to the unfertilized control.en_US
