Abstract
During the summer of 2022, the experiment was carried out at a crop research farm for agricultural research in the department of agronomy. Three different doses of molybdenum (800, 1000, and 1200 g/ha) were applied to the soil as treatments, coupled with zinc (5 kg/ha, 1% foliar spray, 2.5 kg/ha along with 0.5% foliar spray), as well as a control. Ten treatments were used in the experiment, which was designed as an RBD and triple replicated. The highest plant height, maximum number of branches, maximum number of root nodules, plant dry weight, CGR, RGR, and yield parameters, such as more pods per plant, seeds per pod, test weight, seed yield, and stover yield, were observed after the application of 1200g molybdenum with 2.5kg of zinc and 0.5% foliar spray.
