| dc.description | Preliminary evaluations for N fertilizer requirements entailed three N treatments in the nutrient dynamics study. Urea-N was applied to these treatments in three équal split applications to each crop of rice and com. Yield data are shown in Table 1. Upland rice yields declined with 90 kg N/ha due to lodging by the tall-statured local cultivar. In the first two com crops, yields with N rates of 40-120 kg N/ha were not significant1y different. These data suggest that native soil N, and perhaps applied N, carried over in residues of soybean and/or cowpea, were sufficient to limit yield response of com to less than 40 kg N/ha. Nitrogen rates for the third com crop, therefore, were reduced to 20-80 kg N/ha. Com yields significant1y increased in 1986 on1y with applications of 80 kg N. | eng |
