GROWTH, YIELD AND SEED VIABILITY OF FRENCH BEAN VARIETIES AS INFLUENCED BY VERMICOMPOST

Abstract

The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka during the period from December 2017 to February 2018 to study the growth, yield and seed viability of french bean varieties as influenced by vermicompost. Two factors viz. three french bean varieties; V 1 (BARI jhar seem-1), V 2 (BARI jhar seem-2) and V 3 (BARI jhar seem-3) and four levels of vermicompost; Vc 0 (0 t ha -1 ), Vc 1 (6 t ha -1 ), Vc 2 (8 t ha -1 ) and Vc 3 ) were considered for the experiment. The experiment consisting of 12 treatment combinations laid out in Randomized Complete Block Design (RCBD) with three replications. It was noted that the maximum plant height (47.92 cm) was found from the variety, V 3 (BARI jhar seem-3). But the the variety V 1 (BARI jhar seem-1) showed the highest flowers plant -1 (41.09), pods plant (32.09), fresh weight of pods plant -1 (267.19 g), dry weight of pods plant (45.91 g) and fresh pod yield ha -1 (7.13 t). The treatment Vc 3 (10 t ha -1 ) showed the highest plant height (43.31 cm), branches plant -1 -1 (15.20), flowers plant (50.92), number of pods plant -1 (40.82), pod length (11.11 cm), fresh weight of pods plant -1 (342.25 g), dry weight of pods plant (6.53) and fresh pod yield ha -1 -1 (10 t ha -1 -1 (57.56 g), number of seeds pod (9.13 t). Treatment combination of V 1 (BARI jhar seem -1with 10 t ha -1 )

gave the highest flowers plant -1 Vc 3 (52.62), pods plant

(42.56), pod length (11.37), fresh weight of pods plant -1 (367.50g), dry weight of pods plant -1 (61.50 g) and fresh pod yield ha -1 (9.80 t) whereas V 2 (BARI jhar seem-2 with 0 t ha -1 ) had lowest value for all the parameters.

Incase of seed viability test seed germination (96.67%), root length (20.02 cm), shoot length (24.08 cm), and seed vigor index (2348.00) were recorded as maximum with V 1 Vc 3 (BARI jhar seem-1 with 10 t ha -1 vermicompost) where the lowest was obtained from V 2 Vc 0 . Vc 0 -1 -1 -1
