Integrated Nutrient Management of French Bean (Phaseolus vulgaris L.) in Subtropical Humid Zone of Nagaland, India

Background: French bean is one of the most precious and highly relished widely grown short duration legume vegetable. This investigation is intended to assess the integrated manner of nutrient management for higher productivity of French bean under acidic soil condition in subtropical humid zone of Nagaland. Methods: The experiment was carried out during three consecutive years (2017-2018, 2018-2019 and 2019-2020) of rabi season on French bean at Horticultural Research Farm, School of Agricultural Sciences and Rural Development, Medziphema, Nagaland University with the combination of eight treatments. The experiment was laid out in randomized block design with three replications using the variety Arka Komal. Result: The pooled results of three years revealed that the highest growth, quality and yield parameters were observed in treatment T3 (75% NPK through inorganic + 25% N through vermicompost) with maximum plant height (35.68 cm), no. of pods per plant (27.77), no. of seeds per pod (7.01), length of pod (13.96 cm), width of pod (10.58 mm), fresh weight of pod (4.22 g), fresh yield (153.61 q ha-1), crude protein content (28.83%) and benefit cost ratio (4.06) of French bean which was found significantly superior over other treatments.
