SYSTEM OF MUSTARD INTENSIFICATION AS INFLUENCED BY VARIETY AND VERMICOMPOST

Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka to study the system of mustard intensification as influenced by variety and vermicompost during the period from October 2020 to February 2021 in rabi season. The experiment consisted of two factors following randomized complete block design (RCBD) with three replications as factor A: variety (3) viz; V 1 = BARI sarisha-9, V 2 ii = BARI sarisha-14 and V 3 = BARI sarisha15 and factor B: different vermicompost doses (4) viz; F 1 = recommended doses of fertilizer + no vermicompost,F 2 = recommended dose of fertilizer+2 t ha -1 vermicompost, F 3 = recommended doses of fertilize+3 t ha -1 vermicompost, F 4 = recommended dose of fertilizer+4 t ha -1 vermicompost. Data on different parameters were collected for assessing results for this experiment and showed significant variation in respect of growth yield and yield contributing characteristics of mustard due to the effect of variety, vermicompost doses and their combinations. Among different variety, BARI sarisha-9 recorded the maximum number of siliqua plant -1 (597.46), length of siliqua (5.15 cm),seed yield (2.59 t ha ), stover yield (4.35 t ha -1 ), biological yield (6.93t ha -1 ) and harvest index (37.24%) and BARI Sarisha 14 recorded maximum seeds siliqua -1 (32.05), 1000 seeds weight (3.55 g).In case of different vermicompost doses, application of recommended dose of fertilizer + 4 t ha vermicompost treated plot recorded the maximum number of siliqua plant -1 (382.8), length of siliqua (5.77 cm), number of seeds siliqua -1 -1 (29.67), 1000 seeds weight (3.96 g), seed yield (2.26 t ha ), stover yield (3.84 t ha -1 ), biological yield (6.10 t ha -1 ) and harvest index (36.87 %).In case of combined effect, the maximum number of siliqua plant -1 (655.07), length of siliqua (6.46 cm), seed yield (2.96 t ha -1 ), stover yield (4.65 t ha -1 ), biological yield (7.62 t ha ) and harvest index (38.92 %) were recorded in BARI Sarisha-9 (V 1 ) along with recommended doses of fertilizer + 4 t ha -1 vermicompost (F 4 ) treated plot. Whereas number of seeds siliqua -1 (32.67), 1000 seeds weight (4.16 g) were with BARI Sarisha-14 along with recommended doses of fertilizer + 4 t ha -1 vermicompost treated plot. Thus for cultivation of mustard, BARI Sarisha-9 (V 1 ) along with (F 4 ) recommended doses of fertilizer + 4 t ha vermicompost performed well for higher seed production of mustard.
