Response of Sweet Corn (Zea mays L. var. saccharata.) to different Combinations of Nutrient Management

Abstract:

A field experiment entitled “Response of sweet corn (Zea mays L. var. saccharata) to different combinations of nutrient management ” with the variety ‘Sugar -75’ was conducted at Post Graduate Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, during Rabi season 2020. The trial was laid out in Randomized Block Design with nine treatments replicated thrice. The soil of the experimental plot was clay loamy, medium in available nitrogen, medium in available phosphorus, and high in available potassium. The sowing was done on 24 November 2020. The general recommended dose of fertilizer applied was 120:60:40 N: P2O5: K2O kg ha-1+ 10 t FYM ha-1. Application of 125% general recommended dose of fertilizer along with a foliar spray of 2% 19:19:19 NPK at 30 and 45 DAS recorded significantly higher yield attributing traits and growth parameters viz. Cob length, cob girth, number of cobs per plant, number of kernel rows per cob, number of kernels per cob, kernel weight per cob, 100-kernel weight, fresh and dry weight of cob, plant height, leaf area index, dry matter accumulation per plant, number of functional leaves per plant. However, application of 125 % general recommended dose of fertilizer along with foliar spray of 1% 19:19:19 NPK at 30 and 45 DAS was found at par with the application of 125% general recommended dose of fertilizer along with a foliar spray of 2%19:19:19 NPK at 30 and 45 DAS.
