Abstract

An experiment was carried out in the field to ascertain the "Influence of organic manures and zinc on growth, yield and economics of Pearl millet (Pennisetum glaucum L.)” during Zaid 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology, and Sciences Prayagraj (U.P) (Pennisetum glaucum L.). The results showed that treatment 6 [Vermicompost (2.6 t/ha) + Zinc (15 kg/ha)] significantly increased plant height (169.2 cm), dry weight (94.90 g), ear head length (26.4 cm), maximum number of grains/ear head (2046), grain weight/ear head (23.4 g), test weight (9.21 g), grain yield (3.90 t/ha), stover yield (8.20 t/ha), and harvest index (32.24%). In comparison to other treatments, treatment 6 [Vermicompost (2.6 t/ha) + Zinc (15 t/ha)] also had the highest total returns (91919 INR/ha), highest net returns (64269 INR/ha), and highest benefit cost ratio (2.32).
