Nutrient Content, Nutrient Uptake and Soil Nutrient Status of Baby Corn as Influenced by Varieties and Levels of Fertilizers

Abstract

A field experiment was conducted to find out the performance of different baby corn varieties at different levels of fertilizers. The experiment was conducted using three baby corn varieties viz., VL Baby corn-1, CMVL Baby corn-2, and G-5414 and four fertilizer levels viz., 60-40-40 N-P2O5-K2O kg.ha-1, 75-50-50 N-P2O5-K2O kg.ha-1, 90-60-60 N-P2O5-K2O kg.ha-1 and 105-70-70 N-P2O5-K2O kg.ha-1 replicated thrice at the Instructional-cum-Research Farm of Assam Agricultural University, Jorhat during the summer season of 2018 using split plot design. The uptake of N, P and K in cob and total uptake was recorded as the highest for G-5414 and in baby corn Stover it was highest for CMVL Baby corn -2. Application of 105-70-70 N-P2O5-K2O kg.ha-1 resulted in the highest nutrient content and uptake in cob as well as in baby corn Stover. The available soil nutrient after harvest was recorded significantly higher with the application of 105-70-70 N-P2O5-K2O kg.ha-1. The lowest available nutrient was found with the application of 60-40-40 N-P2O5-K2O kg.ha-1. The nutrient content and uptake by baby corn cob as well as by Baby corn stover differs with varieties and increases with increasing levels of fertilizer doses.
