Abstract


Investigations were carried out in soybean (Var:Co 1) with three irrigation scheduling at 60, 80 and 100 mm of cumulative pan value from open pan evaporimeter and six management practices of incorporation of decomposed coconut fibre waste (DCFW) at 12.5 ha-1, split application of potassium 40 kg ha (50 per cent basal and remaining 50 per cent top dressed at 30 DAS and 60 DAS) spraying cycocel 250 ppm, spraying 0,5 per cent at peak flowering stage and incorporation of crystal rain (soil moisturiser) at 12 kg ha-1 and a control. Soybean gave higher yield during Southwest monsoon season as compared to winter sown crop. Scheduling irrigation at 60 mm of pan value recorded higher yield of seed followed by 80 mm and 100 mm in both the seasons. Among the management practices split application of potassium @ 40 kg ha-1 recorded higher yield during Southwest monsoon and incorporation of DCFW in winter sown crop.
