Effect of Bio Fertilizers and Phosphorus on Growth and Yield of Pearl millet (Pennisetum glaucum L.)

Abstract

A research trail was conducted at Crop Research Farm in the Department of Agronomy during kharif season of 2022 on pearl millet. SHUATS, Prayagraj (U.P). To study the effect of bio fertilizers and Phosphorus on growth and yield of Pearl millet. The treatments consisted of 3 levels of Biofetilizers (20 g/kg Azotobacter, 20 g/kg Azospirillum, 20 g/kg Azotobacter+ Azospirillum) and phosphorus (35, 40, 45 kg/ha) and a control. The experiment was laid out Randomized Block Design with ten treatments each replicated thrice. The soil in experimental field was sandy loam 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 showed that application of 20 g/kg Azotobacter+ Azospirillum+ 45 kg/ha Phosphorus was recorded significantly higher plant height (200.13 cm), Plant dry weight (40.33 g/plant), Ear head length (25.25 cm), grains/ear head (2010.9), Grain yield (3.25 t/ha), Stover yield (6.27 t/ha).
