Interaction effect of nitrogen and sulphur on yield, oil and nutrient content of mustard (Brassica juncea L.) in an inceptisol

The pot experiment was conducted during Rabi season of the year 2016-17 followed by laboratory analysis of soil and plant samples in the Department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (UP), India. To accomplish the objective four different levels of nitrogen (0, 50, 100, 150 kg ha-1) and three different levels of sulphur (0, 25, 50 kg ha-1) fertilization experiment was laid out in factorial complete randomized design with three replication. Observations concerning growth and yield parameters of mustard recorded using standard methods. The results divulge that highest seed (18.89 q ha-1) and stover yield (60.25 q ha-1) obtained with treatment T8 (100 kg N ha-1 and 25 kg S ha-1). Oil content of seeds increases with increasing levels S and N but maximum oil content is procured with treatment T8 (37.62%) when both nutrient interacted synergistically with each other. Nutrient content of both seed and stover also increased from control with all the increasing levels of applied nutrients.
