YIELD AND QUALITY OF JUTE SEED AS INFLUENCED BY VARIETY AND STAGE OF POD MATURITY IN LATE SOWN CONDITION

Abstract

The research work was conducted at the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from August, 2017 to December, 2017 to study the yield and quality of jute seed as influenced by variety and stage of pod maturity in late sown condition. Two factors viz. Factor A, three jute varieties; V 1 (O-9897), V 2 (BJRI Tossa Pat-5) and V 3 (BJRI Tossa Pat-6) and Factor B, three stages of pod maturity; M 1 (About 40% pods of the plant become brown), M 2

(About 60% pods of the plant become brown) and M 3 (About 80% pods of the plants become brown) were considered for the experiment. The experiment consisting of 9 treatment combinations and laid out in Randomized Complete Block Design (RCBD) with three replications. The result revealed that variety V 1 (O-9897) showed the highest seed yield (937.33 kgha -1 ) which might be attributed to the highest number of pods plant -1 (22.57), number of seeds pod -1 (176.27) and weight of seeds pod (0.37g). This variety also produced the tallest plant (163.52 cm) and number of branches plant (2.61). Among the harvesting at different pod maturity stages, crop harvested at 60% pod maturity stage (M 2 ) showed the maximum seed yield (962.40 kgha ) which might perhaps the highest number of pods plant -1 (23.22), pod length (6.46 cm), pod diameter (5.66 mm), number of seeds pod -1 (180.02), weight of seeds pod -1 (0.39 g) and weight of 1000 seed (1.99 g) in this treatment. Interaction of V 1 M 2 (Variety O-9897 with 60% pod maturity stage) gave the highest seed yield (1040.80 kgha -1 ) along with the highest number of pods plant -1 -1 -1 (24.97), pod diameter (5.87 mm) and number of seeds pod (185.50). Considering seed quality, variety V 2 (About 60% pods become brown) and interaction of V 2 -1 (BJRI Tossa Pat-5), pod maturity stage M 2 M 2 (BJRI Tossa Pat-5 with 60% pods become brown) gave the best quality of seed in jute. This interaction gave the highest germination (97.0%), seedling length (4.02 cm), seed vigor index (10.26) and oven dry weight of seedling (51.28 mg). -1
