Seed Production of Sunnhemp (Crotalaria juncea L.) as Influenced bySowing Time

摘要

A field experiment was conducted during rabi, 2011 -12 on clay loam soils of the Agricultural College Farm, Bapatla to evaluate the influence of sowing time on the seed production of sunnhemp (Crotalaria juncea L.) in costal eco system. The crop was sown on 1stOctober, 15th October, ls,November, 15th November, 1st December, 15th December, 1st January, 15th January, Is'February and 15tK February respectively. Among the different sowing dates, the crop sown on 1st October recorded significantly higherseed yield (1066 kg ha~(-1)), stalk yield (4485 kg ha~(-1)) gross returns (Rs. 57698 ha~(-1)), net returns (40989 ha~(-1)), returns per rupee invested (Rs 3.45). The crop sown on 1st October received highest heat use efficiency (0.52 and 0.54) than othersowings and lowest was recorded with February sowings (0.19 and 0).
