Abstract
Abstract The influence of sorghum ( Sorghum bicolor L. Moench), sesame ( Sesamum indicum L.) and groundnuts ( Arachis hypogaea L.) unfertilized and fertilized with N and P and of bare and weed fallow on the subsequent season's performance of sorghum and groundnuts was studied in 2‐year trials. The fertilizer rates of 50 kg/ha of N and 22 kg/ha of P applied to the first season's crops affected the yield of the second season's sorghum but not of groundnuts. Two consecutive years of sorghum or groundnuts was deleterious to the second season's yield. Symbiotic fixation in groundnuts was apparently low due to soil acidity and the absence of recent groundnut cultivation. Bare fallow increased moisture by 7.4 mm in the top 1.0 m of soil as compared to weed fallow, but the increase was not reflected in the yield of either crop.
