Effect of Boron and Zinc Fertilization on Yield of Mustard (cv. BARI sarisha-14)

Bangladesh has to import a significant quantity of mustard seeds to meet its growing demand due to the seeds' high oil content and the oilcake, which is rich in protein and used as animal feed. The impact of zinc and boron on mustard (cv. BARI sarisha-14) output was investigated in a field experiment that was carried out at Bangladesh Agricultural University (BAU), Mymensingh, from October 2017 to March 2018. There are five levels of zinc (0, 2.5, 5, 7.5, and 10 kilograms per hectare) and boron (0, 0.5, 1.0, 1.5, and 2.0 kilogram per hectare) in this experiment. Three replications of the experiment, each with a plot size of three meters by two meters, were set up using a Randomized Complete Block Design (RCBD Height of the plant, number of branches per plant, total number of pods per plant, number of effective pods per plant, number of ineffective pods per plant, length of pod (cm), number of seeds per pod, weight of 1000 grains, seed yield, Stover yield, biological yield, harvest index and controlled treatment performed the lowest for these attributes were found when 2.5 kilogram per hectare of zinc were given. The treatment of 1.5 kilogram per hectare boron produced the highest plant height, number of branches per plant, total number of pods, number of effective pods per plant, number of non-effective pods per plant, length of pod (cm), number of seeds per pod, weight of 1000 grains, seed yield, stover yield, biological yield, and harvest index, while the controlled treatment produced the lowest performance. It is noticeable from the growth, yield, post-harvest procedures, and analytical results that the Zn 2.5 kilogram per hectare and B 1 kilogram per hectare combinations were appropriate for mustard farming
