Effect of Bio-fertilizers and Phosphorus on Growth and Yield of Toria (Brassica campestris L.)

Abstract

A field experiment was conducted during Rabi season of 2022-23 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India. To study the Response of bio-fertilizers and phosphorus on growth and yield of Toria. The treatments consist of Bio-fertilizers like Azotobacter – (20g/kg seeds), PSB – (20g/kg seeds), Azotobacter – (10g/kg seeds) + PSB – (10g/kg seeds) and Phosphorus 30, 40, 50 kg/ha. There were 10 treatments each replicated thrice. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%) available N (163.42 kg/ha), available P (21.96 kg/ha) and available K (256.48 kg/ha). Results revealed that the higher plant height (124.54 cm), higher plant dry weight (25.01 g/plant), higher number of branches 11.71), higher number of siliqua (232.53 cm), higher seeds/siliqua (20.60), higher test weight (3.92 gm), higher grain yield (20.6 q/ha) and higher stover yield (3.70 t/ha) were significantly influenced with application of Azotobacter - (10g/kg seeds) + PSB - (10g/kg seeds) + Phosphorus - 50kg/ha.
