Effect of Phosphorous and Boron on Growth and Yield of Rice Bean

Abstract

A field experiment titled “Effect of Phosphorus and Boron on Growth and Yield of Rice Bean” conducted during the Zaid season of 2022 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 Phosphorus and Boron on the growth and yield of Rice Beans. The treatments consist of Phosphorus 20, 40, 60 kg/ha and Boron (Borax 0.01% 20 DAS, Borax 0.02% 40 DAS, and Borax 0.03% 60 DAS). The experiment was laid down in a Randomized Block Design with ten treatments which are replicated thrice. The soil of the experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), and low in organic carbon (0.35%). Results obtained that the higher plant height (106.90 cm), higher number of nodules (30.94), higher number of branches (8.84) higher plant dry weight (49.25 g/plant), a higher number of pods/plant (26.25), higher number of seeds/pod (7.19), higher 1000 seed weight (58.19 g), higher seed yield (2.10 t/ha) and higher stover yield (4.66 t/ha) were significantly influenced with application of Phosphorus 60 kg/ha + Boron 0.03% at 60 DAS. Higher gross return (INR 1,15,500.00 /ha), higher net return (INR 84,155.70/ha) and higher B:C ratio (2.68) were also recorded in treatment-9 (Phosphorus 60 kg/ha + Boron 0.03% 60 DAS).
