Influence of Bio-fertilizer Application Method with Organic and In-organic Fertilizer on Growth and Yield of Bitter-gourd in Winter Season (Momordica charantia L.)

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 Influence of bio-fertilizer application method with organic and in-organic fertilizer on growth and yield of bitter-gourd in winter season .The experiment was consisted of two factors : as- Factor A: Fertilizer (4 levels) T0: control, no fertilizer ,T1: Organic (kitchen compost @1000 kg/ha),T2: in-organic (N46 P40 K 45 ) Kg/ha and T3: Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha Factors B: Bio-fertilizer application method (3 levels) F1: Seed treatment with bio-fertilizer @ 100ml/250g seed,F2: Seedling treatment with bio-fertilizer @400 ml/500 seedling. And F3: Soil treatment with bio-fertilizer @.046 g/m2. The two factorial experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Maximum plant height (299.69 cm),fruit number per plant (19.96), fruit length(27.11 cm), yield/plant (1.05 kg), yield per plot(6.30kg) and total yield (19.44 t/ha) were found from T3F3 treatment. whereas minimum plant height (90.67 cm), fruit number per plant (1.27), fruit length (4.49 cm), yield/plant (.046 kg), yield per plot(.28 kg) and total yield (.86 t/ha) were found from T0F2(control) treatment .All growth related parameter was collected up to 75 DAS due to COVID-19.This study suggests that T3F3 (Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha)+ bio-fertilizer (soil treatment) 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 (T3F3) gave the highest gross return (Tk. 1458000). The lowest gross return (Tk.85600) was obtained in the control condition where no bio-fertilizer as well as no fertilizer was applied. The combination of organic, inorganic and soil application of bio-fertilizer (T3F3) gave highest benefit cost ratio (3.16) and the lowest benefit cost ratio (0.60) was obtained in combination of control condition (T0F2). So, the economic analysis revealed that the treatment T3F3 combination appeared to be the best for achieving the higher growth, yield and economic benefit of bitter gourd.
