Effect of Organic Nutrient Solutions on Growth and Yield Performances of Green Bean (Phaseolus vulgaris L.) in Red Yellow Podzolic Soil in Sri Lanka

Purpose: Liquid Organic Fertilizer (LOF) is one of the essential ways to add extra quantities of minor and major nutrients, plant hormones, stimulants, and other useful ingredients for soil cultivation.
Research Method: The experiment was set up using a Randomized Complete Block Design (RCBD) with seven treatments and four replicates. The treatments were recommended basal and topdressing (Control T₁), 5t/ha poultry manure as basal with foliar spray of 0.5% (T2), 1% (T3), 1.5% (T4) of Vermiwash, 0.5% (T5), 1% (T6), 1.5% of vegetable waste solution (T7). Vermiwash and vegetable waste solution were applied at 1^st, 3^rd, 5^th, and 7^th week after planting.
Findings: The study showed that leaves per plant and number of branches per plant, plant height, number of flowers per plant, dry weight of leaves, and dry weight of stem and roots were significantly (P<0.05) increased in T2 at the 8^th week after planting. The total pick yield achieved in T2 was higher than in tested treatments.
Originality/ Value: This study suggests that the application of 5t/ha poultry manure with 0.5% vermiwash (T2) would be preferable for growing green beans in red-yellow podzolic soil.
