INFLUENCE OF CLYBIO CONCENTRATION WITH APPLICATION FREQUENCY ON GROWTH AND YIELD OF BOTTLE GOURD (Lagenaria siceraria L.)

Abstract

An experiment was conducted to evaluate the influence of Clybio concentration with application frequency on growth and yield of Bottle gourd at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, during the period from January to June 2020. The experiment was consisted of seven treatments namely, T 0 : Control; T 1 : @ 1.0 ml/L+10 days interval; T : @ 1.0 ml/L+15 days interval; T 3 : @ 1.0 ml/L+20 days interval; T 4 2 : @ 2.0 ml/L+10 days interval; T : @ 2.0 ml/L+15 days interval; T : @ 2.0 ml/L+20 days interval. The single factorial experiments were laid out in Randomized Complete Block Design (RCBD) with three replications. Among the treatments the maximum vine length (162.5cm, 360.6cm and 511.4cm at 30, 45, 60 DAT respectively), SPAD value (58.5), number of fruits (11.3/plant), fruit length (45.7cm), fruit 6 diameter(15.5cm), individual fruit weight(3.3kg), yield per plant (38.3kg), yield (95.7t/ha) was found in case of T treatment. On the other hand, minimum vine length (104.1cm, 292.1cm and 383.9cm at 30, 45, 60 DAT respectively), SPAD value (50.3), number of fruits (8.6/plant), fruit length (35.3cm), fruit diameter (10.8cm), individual fruit weight (2.4kg), yield per plant (21.1kg), yield (52.8 t/ha) was found in case of T 0 4 treatment. Considering the effect of applied treatments on growth and yield related results it can be concluded that T ( @ 2ml+10 days i nt erval ) treatment showed the best performance.
