Effect of Integrated Nutrient Management on Growth and Yield of French Bean (Phaseolus vulgaris L.)

The present investigation entitled, “Effect of integrated nutrient management on growth and yield of French bean (Phaseolus vulgaris L.)” was carried out at the research farm of School of Agriculture, Abhilashi University, Mandi (H.P.) during spring season 2022. The experiment was laid out in a randomized block design with three replications. The treatments consisted of conjoint and sole application of organic (FYM and vermicompost) and inorganic fertilizers (urea, SSP and MOP). In terms of soil chemical properties i.e., soil pH (5.6) strongly acidic, organic carbon (0.99%) i.e. high and NPK (260:18:336) kg/ha were maximum observed in treatment T7 (75% RDF of NPK + 12.5% FYM + 12.5% Vermicompost. Out of seven treatments, treatment T7 was recorded best performing for all the traits i.e. days to 50% germination (14.06), leaf area index at 60 DAS (105.32 cm2) and at harvest (130.65 cm2), fresh weight of plant (189.20 g), dry weight of plant (20.03 g), yield per plot (17.45 kg), yield per hectare (290.84q/ha), biological yield (29.47q/ha) and harvest index (59.19%). The maximum gross return (581680 Rs/ha), net return (483209 Rs/ha) and B:C ratio (1:5.9) was also recorded in T7 75% RDF of NPK + 12.5% FYM + 12.5% Vermicompost. Thus, application of optimum doses of NPK along with organic manures was found highly beneficial for plant growth, yield and economics of French bean.
