INFLUENCE OF BIOFERTILIZER APPLICATION METHOD WITH ORGANIC AND INORGANIC FERTILIZER ON GROWTH ANDYIELD OF BITTER GOURD IN WINTER SEASON

Abstract

The experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period of November 2019 – May 2020 to find out the influence of bio-fertilizer application method with organic and in-organic fertilizer on growth and yield of bitter-gourd in winter season. The experimentwas double factorial : as- Factor A: Fertilizer (4 levels) T 0 : control i.e. no fertilizer ,T 1 : Organic (kitchen compost @1000 kg/ha),T : in-organic (N 46 P 40 K 45 ) Kg/ha and T : Organic (kitchen compost @1000 kg/ha) + in-organic (N 23 P 20 K 23 3 ) kg/ha Factors B: Bio-fertilizer application method (3 levels) F 1 : Seed treatment with bio-fertilizer @ 100ml/250g seed,F : Seedling treatment with bio-fertilizer @400 ml/500 seedling. And F 3 2 : Soil treatment with bio-fertilizer @.046 g/m 2 . The double factorial experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Maximum plant height (299.69 cm), fruit diameter(4.6 cm),fruit length(27.11 cm), yield/plant (1.05 kg), and total yield (19.44 t/ha) were found from T 3 F treatment. fruit diameter(1.00cm),fruit length(4.49 cm), yield/plant (.046 kg), and total yield (.86 t/ha) were found from T 0 F 2 3 (control) treatment .All growth related parameter was collected up to 75 DAS due to COVID-19.This study suggests that T 3 F treatment acts as a potential source of plant nutrients for suitable bitter gourd production. The combination of organic ,In-organic and soil application of bio-fertilizer (T 3 3 F ) gave the highest gross return (Tk. 1458000). The combination of organic, inorganic and soil application of biofertilizer (T 3 F ) gave the highest benefit cost ratio (3.16).
