Effect of Poultry Manure, Vermicompost and Boron on Growth and Yield of Maize

Abstract

A field experiment titled “Effect of Poultry Manure, Vermicompost and Boron on Growth and Yield of Maize” (Zea mays L.) was conducted during Rabi 2022 at Crop Research Farm. Department of Agronomy, Naini Agriculture Institute SHUATS, Prayagraj Uttar Pradesh. The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice. Results obtained that combined application of Poultry Manure 50% (1t/ha) along with Vermicompost 50% (2 t/ha) and Boron – 5% (Treatment) significantly increased higher plant height (234.45 cm), plant dry weight (135.84 g/plant) and also yield attributes like effective Number cobs per plant (2.00), Number of Seeds per cob (302.67), Seed index (24.69 g), Grain yield (6.73t/ha), stover yield (15.20 t/ha) and Harvest index (30.68%). The economics viz., maximum gross returns (INR/ha 39,832.43), net returns (INR/ha 84,600.00) and benefit cost ratio (2.48) was also recorded in treatment 9 [Poultry Manure 50% (1t/ha) + Vermicompost 50% (2 t/ha) + Boron – 5%)].
