EFFECT OF WATER-SOLUBLE FERTILIZERS AND BIO STIMULANTS ON GROWTH AND YIELD OF POLE BEAN (PHASEOLUS VULGARIS L.) UNDER PROTECTED CONDITION

An experiment was conducted to study the "Effect of water-soluble fertilizers and bio stimulants on growth and yield of pole bean (Phaseolus vulgaris L.) under protected condition" at department of vegetable science, College of Horticulture, Mudigere during the year 2023-24.The study was laid out in Randomized Complete Block Design with twelve treatments and three replications.The treatments comprised of water-soluble fertilizers (viz., 1 % 19:19:19, 0.5 % monoammonium phosphate and 0.5% potassium nitrate) and bio stimulants (viz., 0.5 % humic acid, 0.5 % sea weed extract and 3 % panchagavya) along with RDF.Among different treatment combinations, foliar application of monoammonium phosphate and potassium nitrate each @ 0.5 per cent with 0.5 per cent humic acid, 0.5 per cent seaweed extract and 3 per cent panchagavya along with RDF (T 12 ) recorded significantly maximum plant height (580.00 cm), number of primary branches (7.20), secondary branches (8.53), number of leaves (154.00),leaf area per plant (5807.01cm 2 ), leaf area index (2.15),total dry matter production (55.79 g) and minimum days to flower bud initiation (35.00 days) and days to 50 per cent flowering (41.07 days).Same treatment also recorded significantly maximum number of pods (55.28), pod length (19.84 cm), pod girth (2.37 cm), pod weight (14.96 g ), pod yield per plant (621.74g) and pod yield per 1000m 2 (2.30 t) over control.
