Abstract:
Rapeseed and Mustard is the third most important oilseed crop in India after Soybean and Groundnut. In addition to this it produces one of the finest qualities of edible oil along with fodder and oil cake. Being a heavy feeder crop it is demands a RDF of 120:60:20 Kg/ha of N:P₂O₅: K₂O. AS the initial crop growth is very slow the 50% basal dose of N applied to is not utilized and lost by various means and hence the aim is to increase the fertilizer use efficiency by manipulating the nitrogen schedule. Also an attempt has been made to supplement the growth and yield by Zn and B application. The experiment was laid out in RBD design with 12 treatments and three replications, i.e., different schedules of nitrogen fertilizer, combined with Zinc (ZnSO₄) and Boron (Borax) in half of the treatments and rest of the treatments without Zinc and Boron. Statistical analysis of experimental data T₈ that involves the application of N at 15, 30 and 45 DAS at the rate of 30, 60 and 30 kg/ha, along with Zn and B was found to be the best treatment in terms of grain and biological yield. T₇ that applied N at 15, 30 and 45 DAS at the rate of 30, 30 and 30 kg/ha, along with Zn and B was found to be the best one in terms of resource saving and economics.
