Integrated Nutrient Management Studies for Higher Productivity of French Bean (Phaseolus vulgaris L.) in Calcareous Soil of Bihar, India.

BIHAR (India); INDIA

Background: French bean is the most important and widely cultivated legume. This research is aimed to evaluate the integrated approach of nutrient management (INM) for higher productivity of French bean (Phaseolus vulgaris L.) in calcareous soil of Bihar, India. Methods: The study was conducted during 2017-18 and 2018-19 on French bean (var. Arka Suvidha) with eight treatments viz T1 (100% NPK through inorganic source), T2 (75% NPK through inorganic + 25% N through FYM), T3 (75% NPK through inorganic + 25% N through Vermicompost), T4 (50% NPK through inorganic + 50% N through FYM), T5 (50% NPK through inorganic + 50% N through Vermicompost), T6 (25% NPK through inorganic + 75% N through FYM), T7 (25% NPK through inorganic + 75% N through Vermicompost), besides an absolute control i.e., T8 (no organic, inorganic applied). The benefit cost ratio was also calculated for comparison of the practical feasibility of various treatment level. The experiment was laid out in randomized block design with three replications. Result: The experimental data on growth and yield attributes were analyzed using analysis of variance technique. The treatment level III i.e. 75% NPK through inorganic + 25% N through Vermicompost) exhibited the highest yield (95.61 q/ha.) and benefit-cost ratio (2.16). [ABSTRACT FROM AUTHOR]
