Abstract:
A field experiment was conducted during Kharif season of 2021 at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (U.P) to investigate the influence of organic manures, inorganic fertilizers and foliar application of zinc on growth, yield and economics of maize. The treatments consisted of organic manure and inorganic fertilizer in combinations and foliar zinc application, whose effect is observed on maize (var. BISCO-UJALA). The experiment was laid out in randomized block design with ten treatments replicated thrice. Study revealed that application of 50% N through Vermicompost + 50% N through inorganic fertilizers recorded significantly higher plant height (221.08 cm), number of leaves per plant (14.53), plant dry weight (198.29 g), number of cobs per plant (1.60), number of grains per cob (416.73), grain yield (8.18 t/ha), Stover yield (18.70 t/ha) and harvest index (29.34%) as compared to other treatment combinations. The higher gross return (INR 130880.00/ha), net return (INR 83182.30/ha) and B:C ratio (2.74) was recorded with the application of 50% N through vermicompost + 50% N through inorganic fertilizers as well.
