GERMINATION AND SEEDLING GROWTH OF SOME VEGETABLES UNDER AQUEOUS LEAF EXTRACTS OF SIX HERBAL PLANTS

Abstract

An experiment was conducted in the research laboratory of the department of Agricultural Chemistry, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during March 2011- March 2012 to study the effects of aqueous leaf extracts of some herbal plants on the germination and seedling growth of vegetables. The treatments were T, -Water or control,T,;-Aqueous extract of basak,T,= Aqueous extract of ulot komal,T;=Aqueous extract of neem, T, = Aqueous extract of bel,T;-Aqueous extract of akando and Ts=Aqueous extract of horitoki. The experimentwas laid out following CRD with three replications. Cucumber, lady’s finger and yard long bean were selected. Significantly the fastest 50% germination occurred with horitoki (Ts = 4.33 days) followed by T, T3, Ty and T; where as the slowest 50% germination occurred with control (Tp =6.33 days). At 20 DAS, 25 DAS and 30 DAS the highest shoot length was recorded in case of seed treated with horitoki leaf extract (44.27 cm, 62.17 cm and 83.10 cm, respectively). Horitoki showed the best result (8. 67 cm) whereas control showed the lowest root length (5.73 cm) followed by seed treated with basak leaf extract
