Abstract
Field experiments were carried out on sandy loam soil at Varanasi during pre -kharif season of 2004 and 2005 to evaluate appropriate fertility levels and N sources for baby corn ( Zea mays L.). Experiment was laid out in splitplot design and replicated thrice with three fertility viz. F , 60 + 12.9 + 24.9; F , 120 + 25.8 + 49.8, and F , 1 2 3 180 + 38.7 + 74.7 kg N+P+K/ha in main plots and three N sources viz. 100% N by fertilizer, 75% fertilizer N + 25% N by FYM and 50% fertilizer N + 50% N by FYM as sub plots. Significant increase in baby corn and green fodder yield and quality parameters (carbohydrate, sugar, starch, protein, N, P and K content and uptake) in baby corn were recorded with application of 120 + 25.8 + 49.8 over 60 + 12.9 + 24.9 kg N+P+K/ha. However, net returns increased significantly with each successive increase in fertility level upto highest fertility levels i.e. 180 + 38.7 + 74.7 kg N+P+K/ha. Application of N through fertilizer alone recorded significantly higher baby corn yield (2.30 t/ha mean) and net returns (Rs. 1,10,983/ha) over 50% fertilizer N + 50% N through FYM. Available N, P and K in the soil after baby corn harvest were highest with 180 + 38.7 + 74.7 kg N+P+K/ha and 50% N supplied through FYM.
