Effect of Sowing Times on Yield Attributes of an Exotic (China) Hybrid Rice Variety in Bangladesh |

During the months of January to April 2014, this experiment was conducted at Sher-e-Bangla Agricultural University's (SAU) Agricultural Botany experimental field in Sher-e-Bangla Nagar, Dhaka, to investigate the effect of sowing times on the yield attributes of an exotic (China) hybrid rice variety in Bangladesh. Regarding five sowing or transplanting dates, five treatments were considered: I S1 = 1st sowing on January 1st, 2014; transplanted on January 21st, (ii) S2 = 2nd sowing on January 21st; transplanted on February 11th, (iii) S3 = 3rd sowing on February 11th; transplanted on March 3rd, (iv) S4 = 4th sowing on March 3rd; transplanted at 23rd March and (v) S5 = 5th sowing at 23rd March; transplanted at 13th April. Data were recorded on different growth parameters to examine the effect of sowing times on the yield attributes of the tested variety. The studied parameters were significantly affected by different sowing times or transplanting times. Results revealed that different parameters regarding yield attributes, the seeds of the test variety sown at 1st January 2014 and transplanted at 21st January (S1) furnished the best results in respect of the weight of filled grain hill-1 (38.87 g), weight of filled grain plot-1 (2.18 kg), 1000 seed weight (36.00 g), grain yield ha-1 (3.64 ton) and the highest harvest index (43.46%) compared to the seedling transplanted on other dates or times. These findings can be used in further breeding program.
