Abstract:
An experiment was conducted during rabi season of 2019-20. The experiment was laid out in a split plot design with three replication. The main plots consisted of two varieties (V1- Sugar- 75 and V2- Sweet- 16) and three split application of nitrogen (N1- 50.0% N as basal + 50.0% N at knee height stage, N2- 25.0% N as basal + 50.0% N at knee height stage + 25.0% N at tasseling stage and N3- 33.3% N as basal + 33.3% N at knee height stage + 33.3% N at tasseling stage), whereas sub plot consisted of three harvesting schedule (T1- 20 days after silking, T2- 30 days after silking and T3- 40 days after silking).
An experiment was conducted during rabi season of 2019-20. The experiment was laid out in a split plot design with three replication. The main plots consisted of two varieties (V1- Sugar- 75 and V2- Sweet- 16) and three split application of nitrogen (N1- 50.0% N as basal + 50.0% N at knee height stage, N2- 25.0% N as basal + 50.0% N at knee height stage + 25.0% N at tasseling stage and N3- 33.3% N as basal + 33.3% N at knee height stage + 33.3% N at tasseling stage), whereas sub plot consisted of three harvesting schedule (T1- 20 days after silking, T2- 30 days after silking and T3- 40 days after silking).
The results indicated that variety Sugar-75 recorded significantly higher values of plant height, number of leaves plant-1, length of cob, weight of cob, green cob yield, fresh kernel yield, green fodder yield, gross and net realization. Whereas, variety Sweet-16 produced maximum girth of cob. N1 recorded significantly higher values of plant height at 45 DAS and number of leaves plant-1. Whereas, N2 produced maximum plant height at 60 DAS and at harvest, number of internode, length of internode, dry matter accumulation, length of cob, weight of cob, fresh kernel weight cob-1, green cob yield, fresh kernel yield, green fodder yield, higher gross and net realization. Girth of cob, weight of cob, fresh kernel weight cob-1, green cob yield, fresh kernel yield and green fodder yield were found significantly higher when crop was harvested at 30 days after silking followed by 40 days after silking. Whereas, length of cob was found significantly higher when crop was harvested at 30 days after silking followed by 20 days after silking. Maximum gross realization (₹ 171062 ha-1) and net realization (₹ 102070 ha-1) along with higher B:C ratio of 2.48 were observed under harvesting at 30 days after silkig followed by harvesting at 40 days after silking. Interaction effect between varieties and split application of nitrogen were observed significant for length of cob. Interaction effect between varieties and harvesting schedule were obtained significant for length of cob. This study recommends the use of variety Sugar-75, split application of 25.0% N as basal + 50.0% N at knee height stage + 25.0% N at tasseling stage and harvest at 30 days after silking to produce the greatest sweet corn cob per hectare.
