Abstract
Field experiments were conducted during late Rabi (January to March) and Kharif (June to September) seasons of 2002, to study the influence of foliar spraying of nutrients on growth and yield of baby corn (Zea mays L.). The experiment was laid out in randomized complete block design with three nutrients (phosphorous [P], potassium [K] and boron [B]) each at three concentrations along with control (water spray) and absolute control (no spray). Di-ammonium phosphate, Muriate of Potash and Borax are the sources of P, K and B nutrients respectively. Results showed that spraying of P favorably influenced the growth parameters, yield attributes and green cob and fodder yields of baby corn. Application of P at 0.75% concentration at 25 and 45 days after sowing (DAS) gave significantly higher growth parameters with thicker cobs and corns, increasing the individual cob weight, which in turn increased the green cob yield of baby corn. Increased growth parameters resulted in increased green fodder yield. Application of B and K with different concentrations and P (0.25 and 0.50%) failed to influence the growth and yield of baby corn.
