EFFECT OF MYCORRHIZA, NITROGEN, AND PHOSPHOROUS ON NODULATION, GROWTH, AND YIELD OF CLUSTER BEAN (GUAR)

Abstract

A single season field experiment was carried out in the Demonstration Farm of the College of Agricultural Studies Sudan Univarsity of Science and Technology at Shambat in the summer season of 2011. The experiment was aimed to study the effect of mycorrhiza, nitrogen, and phosphorus fertilizer on the nodulation, growth, and yield of Cluster bean (guar). The experiment was carried out in a randomized complete block design with four replicates. The treatments were: control, inoculum, inoculum + mycorrhiza, inoculum + mycorrhiza + 100kg NPK 23:23:0/ha, and inoculums + inoculum + mycorrhiza + 200kg NPK (23-23-0/ha). The treatment inoculum + mycorrhiza + 200kg NPK 23-23-0/ha resulted in the highest growth rates, grain yield, and number of pods per plant with statistically significant differences over the other treatments.
