Transplanted (T.) aman rice is the major crop in the southwestern coastal region of Bangladesh where most of the fields remain fallow the rest of the year due to the cultivation of late-maturing and long-duration aman rice varieties with low yield potential. Timely transplanting of short-duration HYV varieties increased grain yield and allowed the field to be cleared earlier for the next crop. The experiment was conducted in the experimental field of Agrotechnology Discipline, Khulna University, Khulna during the monsoon (June to December) for investigating the influence of transplanting dates on growth, yield attributes, and yield of Binadhan-7. The experiment was laid out in a randomized complete block design and replicated thrice. The experimental treatment comprised of ten transplanting dates (viz.,9 July, 16 July, 23 July, 30 July, 6 August, 13 August, 20 August, 27 August, 3 September, and 10 September) at 7 days intervals. Data recorded on different growth, yield, and yield contributing parameters were influenced substantially by the dates of transplanting. Results of this study showed that transplanting on 30 July produced the tallest plant (105.40 cm), highest tiller hill-1 (20.40), effective tillers hill-1 (17.30), panicle length (22.22 cm), number of grain panicle-1 (10.34), 1000 grain weight (22.83 g), grain yield (4.72 tha-1), straw yield (5.15 tha-1) and harvest index (47.85%) which were on parity with 6 August of transplanting. From the findings of this study, it can be concluded that from 30 July to 6 of August is optimum and recommended transplanting window for the short duration aman rice variety (Binadhan-7) in the coastal zone of southwestern Bangladesh. Furthermore, this transplanting window resulted in an early harvest and timely vacant the field for winter crop planting.

“…It was the genetical attributes that have shown variation in harvest index of different varieties. Tyeb (2012) and Mahmud et al (2017) observed the similar results and concluded that harvest index depended on inherent genetical attributes on same environmental conditions.…”

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the period from July to December 2019 to study the effect of cultivar and seedling age on the performance of short duration transplant Aman rice. The experiment comprised four Aman rice cultivars, viz., BRRI dhan49, BRRI dhan56, BRRI dhan66 and BRRI dhan71, and four seedling ages viz. 20, 25, 30 and 35-day old seedlings. The experiment was laid out in a randomized complete block design with three replications. Results of the study showed that growth, yield and yield contributing characters were significantly influenced by cultivars, seedlings age and their interactions. At growth stage, BRRI dhan49 with 20-day old seedlings produced the tallest plant (57.67 cm and 67.33 cm, respectively), the highest number of total tillers hill-1 (15.00 and 13.67, respectively) and total dry matter (8.03 g m-2 and 11.50 g m-2, respectively) at 30 and 50 DAT. At harvest, the highest number of total and effective tillers hill-1 (12.82 and 12.00), longest panicle (24.50 cm), highest number of grains panicle-1 (128.80), heaviest 1000-grain weight (23.17 g), highest grain yield (5.35 t ha-1) and highest harvest index (51.69 %) were obtained from the cultivar BRRI dhan66. While, thirty-day old seedlings produced the highest number of total and effective tillers hill-1 (13.46 and 12.70), longest panicle (24.67 cm), highest number of grains panicle-1 (136.90), highest grain (5.62 t ha-1) and straw yields (5.81 t ha-1) and harvest index (51.67 %). In case of interactions, BRRI dhan66 with 30-day old seedlings produced the highest number of total and effective tillers hill-1 (14.67 and 13.97), longest panicle (26.00 cm), highest number of grains panicle-1 (146.7), highest grain yield (6.31 t ha-1) and highest harvest index (52.72 %). So, result of the present study reveals that BRRI dhan66 with 30-days old seedlings was found to be the best for obtaining maximum grain yield.
