“…Biological yield was ranged from 5.70 to 15.49 t ha -1 and the highest biological yield (15.49 t ha -1 ) in spacing of 25 cm ×15 cm with weed free treatment which was statistically identical to biological yield (14.98 t ha -1 ) was produced in spacing of 25 cm × 15 cm with weed free up to 80 DAT and followed by to biological yield (14.49 t ha -1 ) in 25 cm× 15 cm spacing with weed free up to 60 DAT. This result is supported by Hossain (2002).…”

“…Hossain results revealed that the highest biological yield (11.65 t ha -1 ) was obtained from SRI planting method which the spacing of 25 cm ×15 cm and the lowest (7.49 t ha -1 ) was in conventional planting method with the spacing of 25 cm × 15 cm (Hossain, 2002). From Hossain it is evident that weed interference period and plant spacing have strong influence on the productivity of rice (Hossain, 2002). That is why, it is important to examine the effect of weed interference period and plant spacing on the yield and yield contributing attributes of BRRI dhan29.…”

To study the influence of weed interference period and planting spacing on the weed pressure and performance of Boro rice cv. BRRI dhan29 an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University from December 2015 to May 2016. The experiment comprised six weed interference periods (viz. weed free, weed free up to 20 DAT, weed free up to 40 DAT and weed free up to 60 DAT, weed free up to 80 DAT and weedy condition) and three spacing of planting (viz.25 cm × 15 cm, 25 cm × 10cm, 25 cm × 20 cm) following randomized complete block design with three replications. The highest number of total tillers hill-1 (14.98), effective tillers hill-1 (12.98), filled grains panicle-1 (117.9), grain yield (5.40 t ha-1), straw yield (7.94 t ha-1) and biological yield (40.53 t ha-1) were found weed free up to 80 DAT. Considering cost and time consuming, best tillers hill-1 (15.88), effective tillers hill-1 (13.88), filled grains particle-1 (121.70) and grain yield (6.14 t ha-1) were found in spacing 25 cm × 15 cm with weed free up to 80 DAT. Weed density and dry weight were increased with the increasing weed interference period but rice grain yield increased gradually with the decreasing weed interference period. Weed free up to 80 DAT can be recommended from economic view point following the spacing of 25 cm × 15 cm for better weed suppression and higher yield of BRRI dhan29.

“…In Batiaghata, the highest straw yield was found in BRRI dhan84 (2.57 t/ha) followed by BRRI dhan67 (2.51 t/ha) but they were statistically insignificant. Medium plant height, short duration and high yield can be the reason of low straw weight (22). Studies revealed that straw yield might be assigned to plant height and straw weight differed significantly due to varieties (14).…”

An experiment was carried out in Boro season during November 2018 to April 2019 at two farmer’s fields of Batiaghata and Dumuria sub-district under Khulna district of Bangladesh with the objective of testing agronomic status and adaptability of four modern rice varieties in comparison with the popular mega variety BRRI dhan28. The varieties were BRRI dhan67, BRRI dhan81, BRRI dhan84 and BRRI dhan86. BRRI dhan28 was chosen as a control due to its wide acceptability among the farmers. The soil of the studied area was moderately alkaline and medium to moderately saline. In Batiaghata and Dumuria field, initial soil EC was 3.19 and 3.29 dS/m, respectively and it was 4.7 and 4.8 dS/m, accordingly at maturity stage. It was observed that germination rate, plant height, effective tiller number were significantly higher in BRRI dhan67 than the other varieties but insignificant with BRRI dhan28 (p≤0.05) for both fields. All the yield components spikelets per panicle, filled grain and 1000-grain weight were also significantly higher in BRRI dhan67 in compared to the other varieties but insignificant with BRRI dhan28 (p≤0.05) for both fields as well. The highest grain yield was observed in BRRI dhan67 in both plots (7.89 and 7.29 t/ha) and showed significant differences among all other varieties (p≤0.05). Harvest Index of BRRI dhan67 (51.02±4.2, 57.84±8.6)% indicated that this variety is the best yielder among the varieties. Considering overall performances and facts, BRRI dhan67 showed better agronomic performance and adaptation than the other modern varieties in compare with popular mega BRRI dhan28.

“…The highest grain yield of SRI planting method was mostly the outcome of higher total number of tillers hill -1 , highest panicle length and highest number of grains panicle -1 . Conventional planting method produced the lowest grain and straw yields (3.65 and 4.29 t ha -1 ) respectively Hossain et al, (2003). The grain yield and water productivity were significantly increased at SRI planting with 14 days dapog seedlings planted at 25 x 25 cm spacing to achieve 7009, 5655 kg ha -1 and 0.610 kg and 0.494 kg m -3 of water respectively in wet and dry season Vijayakumar et al, (2006).…”
