After rice harvest, mustard was grown in the same layout to study the residual effect of FA, organic wastes and CF applied to the previous crop. Each plot was divided into two. One received a standard dose of fertilizer i.e., 60:17:33 kg N:P:K ha−1 supplied through CF and the other half without it in a random manner. Thus, the residual effect of fertilization sources with direct application of CF (Re + CF) or without it (Re) was studied. The experimental design thus followed was a split plot with three replications. Mustard seed was drilled in rows at a 30 cm spacing. At the two-week stage, excess seedlings were thinned out and a uniform plant population was maintained by keeping the intra-row spacing of 10 cm. The crop was irrigated at critical physiological stages viz., branching, flowering, podding and seed set.
