EFFECT OF VERMICOMPOST ON GROWTH AND YIELD OF POTATO (Solanum tuberosum L.)

Abstract

An experiment was carried out at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka during the period from November 2014 to February 2015 to evaluate the effect of vermicompost on growth and yield of potato. The experiment was laid out in a Randomized Complete Block Design with three replications. The experiment consisted of two factors viz., three varieties (V 1 = Diamant, V 2 = Cardinal and V = Lady Rosetta) and four levels of vermicompost (T 0 = Control, T 1 iii

3 = Vermicompost at 6 t ha -1 , T = Vermicompost at 8 t ha -1 and T 3 = Vermicompost at 10 t ha -1 2 ). Results revealed that variety and vermicompost and also their interaction had significant effect on all growth parameters and yield contributing characters. In case of variety, and vermicompost the highest tuber yield (24.64 t ha -1 ) and (26.30 t ha ) were found from V 1 and T respectively. In terms of combined effect the highest number of tuber hill -1 2 (8.1), weight of tuber hill -1 -1 (343.3 g), tuber weight plot

(6.18 kg), dry weight of 100 g tuber (23.2 g) and the highest tuber weight ha

(27.47 t) were obtained from V 1 T . So, it can be concluded that vermicompost 8 t ha

-1 can be used as organic manure.
