INFLUENCE OF SOWING TIME AND SEED RATE ON THE GROWTH AND YIELD OF BARI Mung-6

Abstract

The experiment was conducted at Regional Pulse Research Centre, BARI, Madaripur, Bangladesh during the period of March to June, 2018 to evaluate the influence of sowing time and seed rate on the growth and yield of BARI Mung6 for achieving higher yield. The experiment comprised two factors: Factor A:

Sowing time (3 times) as - T 1 = Sowing on 01 March, 2018, T 2 = Sowing on 10 March, 2018 and T 3 = Sowing on 20 March, 2018; and Factor B: Seed rate (4 levels) as - S 1 = 20 kg seeds ha -1 , S 2 = 25 kg seeds ha ii -1 , S 3 = 30 kg seeds ha and S 4 = 35 kg seeds ha -1 . The experiment was laid out in split-plot design with four replications. Data were recorded on different morphological, yield contributing characters and yield of BARI Mung-6. Results revealed that T 2 (10 March) gave the highest seed yield (1.33 t ha -1 ). This may be attributed to the maximum number of pods plant -1 (32.39), pod length (9.12 cm), number of seeds pod

(13.10), weight of 100-seed (5.34 g). Considering seed rate, S 3 (30 kg ha ) was the highest seed yielder (1.32 t ha -1 ) which may perhaps the maximum number of pods plant -1 (32.32), pod length (9.38), number of seeds pod -1 (13.08), weight of 100-seed (5.30 g). Among the treatment combinations, the maximum number of pods plant -1 (34.5) and weight of 100-seed (5.51 g) were found from T 2

which was statistically similar with T 2 S 4 , T 3 S 3 . In case of seed yield, the highest seed yield (1.43 t ha -1 ) was exhibited from T 2 S 3 treatment combination which was statistically similar with T 2 S 4 , T 3 S 2 , T 3 S 3 . From the present study it may be concluded that, the mungbean grower may cultivate BARI Mung-6 under prevailing climatic condition of greater Faridpur region in the month of March 10-20 along with 25-35 kg ha

-1 seed rate to get the maximum seed yield.
