Abstract:
A field investigation was conducted at Agronomy Research Farm, College of Agriculture, Central Agricultural University, Imphal during Rabi season of 2019-20. The experiment was laid out in Factorial Randomized Block Design (FRBD) with three replications. The present investigation disclosed that among the three row spacings, crop sowed at 40 cm (S₃) recorded significantly higher growth attributes viz., plant height, fresh and dry weight of plant and number of branches/plant. Furthermore, yield parameters viz., number of pods/plant and number of seeds/pod were also recorded higher in wider (40 cm) row spacing but seed yield, stover yield and harvest index were found higher in 30cm row spacing. Among the different mulches, paddy straw mulch 10t/ha (M₃) showed the most significant effect on plant height, number of branches, pods/plant, number of seeds/pod, seed yield, stover yield. Significantly higher seed yield was obtained at 30cm row spacing with paddy straw mulching (12.79 q/ha).
