Influence of Biofertilizers and Phosphorus on Growth, Yield and Economics of Field Pea (Pisum sativum, Fabaceae)

Abstract

The field experiment was conducted during Rabi season, 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The objective was to study the influence of Biofertilizers and Phosphorous application on growth and yield of field- pea (Pisum sativum L.). The results showed that treatment 9 [Phosphate-solubilizing bacteria (PSB) + Rhizobium along with (70 kg/ha) Phosphorus (P2O5)] recorded significantly higher plant height (54.75 cm), more number of branches/plant (5.15), maximum plant dry weight (8.99 g/plant), maximum pod length (8.05), maximum number of pods/plant (24.97), higher number of grain/pod (7.24), maximum test weight (44.74 g), higher seed yield (16.25 q/ha), higher stover yield (37.11 q/ha) compare to other treatment. The maximum gross return (141133.00 INR/ha), maximum net return (101262.45 INR/ha) and the highest Benefit cost ratio (2.53) was also recorded in treatment 9 as compared to other treatments. Thus the best combination to get maximum growth, yield attributes and economics in field-cultivated Pea (Pisum sativum) was found [PSB + Rhizobium inoculation + 70 kg/ha (P2O5)].
