Effect of Organic Fertilizer, Nitrogen, Phosphors and Inoculum on nodulation, Growth, and Yield of Cluster Bean (Guar

Abstract

To study the effect of compost, inoculums, and starter nitrogen on nodulation, growth, and yield of cluster bean, field experiment was conducted on the demonstration farm of the Collage of Agricultural Studies, Sudan University of Science and Technology at Shambat. The experiment was sown on Shambat loamy clay soil on July, 2009. A split plot design was 9 used with main plo(Compost) with and without . Four sub-plots namely control, inoculums, inoculum + half dose nitrogen, and inoculums + one dose nitrogen (dose = 43 kg N/ha in form of NPK (23:23:0). The treatment were replicated three times The result showed no significant differences among the treatment in all parameter studies except for the relative growth rate. However, the differences were not sufficient enough to be reflected in the primary morphological yield components and eventually on the grain yield.
