YIELD AND QUALITY OF JUTE SEED AS INFLUENCED BY VARIETY AND SOWING DATE AT LATE SOWN CONDITION

Abstract

The research work was conducted in the net house of the department of agronomy, Sher-eBangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from July, 2019 to

December, 2019 to study the yield and quality of jute seed as influenced by variety and sowing

date at late sown condition. The two-factor experiment was laid out in the Randomized Complete

Block Design RCBD (factorial) with three replications. Two factors viz. Factor A, four jute varieties;

V 1 = BJRI Tossa Pat-8, V 2 = BJRI Tossa Pat-6, V 3 = BJRI Tossa Pat-5 and V 4 =O-9897; and Factor B; four sowing dates S 1 = July 7, S 2 = July 21, S 3 = August 7 and S 4 = August 21 were considered for the experiment. The result revealed that variety V 3 (BJRI Tossa Pat-5) showed the highest seed yield (1303.94 kgha 1 (27.78), number of seeds pod -1 -1 ) which might be attributed to the highest number of pods plant (176.48) and weight of seeds pod -1 (0.40g). This variety also produced the tallest plant (171.63cm) and maximum number of branches plant (3.73). Among the different sowing dates, crop sown at 7 August (S 3 ) showed the maximum seed yield (1203.74 kgha -1 ) which might perhaps the highest number of pods plant -1 (24.75), pod length (6.76 cm), pod diameter (5.80 mm), number of seeds pod -1 (175.96), weight of seeds pod (0.39 g) and weight of 1000 seed (1.79 g) in this treatment. Interaction of V 3 S 3 (Variety BJRI Tossa Pat-5 with sowing date August 7) gave the highest seed yield (1390.2 kgha -1 ) along with the highest number of pods plant -1 (29.98), pod diameter (6.26 mm) and number of seeds pod -1 (186.26). Considering seed quality, the interaction V 3 S 3 also showed the highest germination (97.66%), seedling length (4.97 cm), oven dry weight of seedling (51.59 mg) and lowest electrical conductivity (8.17 dSm ). Considering the above result, it may be concluded that variety V 3 1303.94 kgha and sowing date S 3 1203.74 kgha -1 and its interaction V 3 S 3 1390.2 kgha -1 seems promising of jute seed production in late sown condition.
