Abstract: Application of a compound fertilizer to supply 224 kg/ha each of N, P2Og and K^O in 5 equal doses during flowering, increased the yield of June-sown dwarf pigeon peas by 25% over the untreated control. The same total quantity during vegetative growth or over the entire growth period gave much lower yields. The Ν and Ρ contents of a standard leaf were increased by fertilizer application, but neither leaf-N nor-P appeared related to yield. Fertilizer application to a November-sown high density crop increased the yield of only one of three cultivars, in an experiment in which yields were very poor. Nitrogen alone decreased yields in a September-sown trial as did MNS04 as spray or soil drench and complete fertilizer as drench. The effects of fertilizers on branch number and plant height were generally small and variable.
