Response of Bio Fertilizers and Phosphorus on Yield and Economics of Pearl millet (Pennisetum glaucum L.)

Abstract

A field experiment was conducted during kharif season of 2022, at crop research farm, Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.).India. The objective is to study the Response of Bio fertilizers and Phosphorus on yield and economics pearl millet. The treatments consisted of three levels of Bio fertilizers (20 g/kg Azotobacter, 20 g/kg Azospirillum, 20 g/kg Azotobacter + Azospirillum) and three levels of phosphorus (35, 40 and 45 kg/ha). The experiment was laid out in randomized block design with the ten treatments combinations replicated thrice. The soil in experimental field was sandy loam in texture, having alkaline reaction (pH 7.7) with very low organic carbon (0.44%), available higher N (171.48 kg/ha), P (27.0 kg/ha) and higher level of K (291.2 kg/ha).The results show significantly higher in  yield attributes viz. ear head length (25.25 cm), number of grains/ear head (2010.9),and yield viz. grain yield (3.25 t/ha) and Stover yield (6.27 t/ha). Maximum gross return (113750.00 INR/ha), net return (81010.00 INR/ha) and Benefit - cost ratio (2.47) was found in treatment (T9) with the application of 20 g/ kg Azotobacter + Azospirillum + 45 kg/ha Phosphorous.
