Effect of Fertigation and Nano Formulated Nutrients on Growth, Yield and Quality of Pole Bean (Phaseolus vulgaris L.)

An investigation was carried out in the department of Vegetable Science, College of Horticulture, Bagalkot, University of Horticultural Sciences, Karnataka during 2023-24. The objective was to study the “Effect of fertigation and nano formulated nutrients on growth, yield and quality of pole bean (Phaseolus vulgaris L.)” with sixteen treatments replicated twice. The study used different concentrations of fertigation levels and nano nutrient formulations. The higher fertigation level F₃, recorded maximum growth and yield parameters. Between two different concentrations of nano DAP at 4 ml/lt reported higher readings in observations. Among different treatment combinations, the growth, yield and quality attributes were shown maximum in the F₃N₂, plant height (296.50 cm), number of branches per plant (12.30), leaf area (136.51 cm²), chlorophyll content (60.60 SPAD units), pod length (16.37 cm), pod girth (2.83 cm), pod weight (14.92 g), pod yield per plant (212 g), pod yield per hectare (33.74 t), crude protein and fiber (26.60% and 4.70%, respectively).
