Effect of Organic Manures and Nano Zinc on Growth and Yield of Baby Corn (Zea mays L.)

A field experiment was conducted during kharif 2022 at CRF (Crop Research Farm), Department of Agronomy, SHUATS, Prayagraj, (UP). To study the “Effect of organic manures and Nano zinc on growth and yield of baby corn”. The soil of the experimental field is sandy loam in texture. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. The treatments consisted of three levels of Nano zinc (0.5 ml/l, 1 ml/l, 1.5 ml/l) and three levels of organic manures whose effect is observed in baby corn. The results revealed that the treatment with application of poultry manure 3.3 t/h + Nano zinc 1.5ml/l recorded higher plant height (191 cm), plant dry weight (99.60 g), number of cobs (3.73), cob length 21.95 cm, cob weight with husk 10.88 g, cob yield without husk 6.38 t/h, green fodder yield 36.10 t/h and harvest index (39.03%). The economics viz., maximum gross returns (1,81,170.00 INR/ha), net returns (1,20,155.00 INR/ha) and B:C (1.97) was also recorded in treatment 9 with application of poultry manure 3.3t/h + Nano zinc 1.5 ml/l.
