Effect of sowing dates on plant growth and yield of hybrid sweet corn

The study was conducted at Tansa Farm, ASPEE Agricultural Research and Development Foundation, Maharashtra during 2015-16. The four sowing dates viz. 15th December, 30th December, 15th January, 30th January and three hybrid sweet corn varieties viz. Hibrix 39, Madhu 5 and Sugar 75 was studied. The experiment was laid out in Randomized Block Design (RBD) with three replications having net plot size 6.6 m x 4.5 m. Yield components and plant growth parameters such as plant height, cob length, cob weight, seeds per cob, test weight and grain yield of sweet corn varieties were significantly affected by different sowing dates. All quantity traits were promising when the sowing was carried out on 15th December. Further delay of the sowing had negative effects on the performance of quantity of sweet corn varieties. Hybrid sweet corn var. Sugar 75 was recorded promising variety which gave higher grain yield of 2381 kg ha-1.
