Residual soil fertility and nutrient uptake in baby corn as influenced by nutrient sources and weed control measures
Year: 2015
Type: article
Abstract: A field experiment was conducted at Indian Agricultural Research Institute, New Delhi to assessthe effect of nutrient sources and weed control measures on nutrient uptake, yield and residualsoil fertility after harvest of baby corn. The highest husked and dehusked baby cob yields (4.43 tha–1 and 2.15 t ha–1, respectively) and green fodder yield were obtained with application of Nthrough vermicompost and the lowest (3.30 and 1.80 t ha–1, respectively) was recorded with theapplication of N through fertilizer. Residual fertility in terms of available N, P and K (186.5, 18.0and 208.2 kg ha–1) in the soil after crop harvest was significantly superior when 120 kg N ha–1 wasapplied through FYM in comparison with recommended dose of N applied through fertilizer andit was at par with leaf compost and vermicompost. In case of weed control measures, the highesthusked and dehusked cob yield (4.29 t ha–1 and 2.18 t ha–1 respectively) and green fodder yieldswere found in weed free treatment and the lowest values were obtained from unweeded control(3.05 t ha–1 and 1.68 t ha–1 respectively). Available N, P, K, bulk density and organic carbon in soilwas not significantly varied due to weed control measures.
