YIELD PERFORMANCE OF T. AMAN RICE VARIETIES UNDER DIFFERENT TRANSPLANTING DATES (Pages : 1 - 8)

An experiment was conducted at the Agronomy Field Laboratory, Patuakhali Science and Technology University (PSTU), Patuakhali during the Aman Season from July to December 2016 with a view to determining the effect of transplanting dates on yield and yield attributes of different T. Aman rice. The experimental treatments comprised of three transplanting dates viz. 25 July, 10 August and 25 August and four T. Aman rice varieties viz. BR23, BRRI dhan41, BRRI dhan49 and BRRI dhan72. The experiment was laid out in a split-plot design with 3 replications. The highest straw yield (7.62 t ha-1) was found on 25 July transplanting. The grain yield (6.30 t ha-1), biological yield (13.19 t ha-1) and harvest index (47.70%) were highest on 25 August transplanting. BRRI dhan49 produced the highest grain yield (6.62 t ha-1), straw yield (7.84 t ha-1), biological yield (14.47 t ha-1) and harvest index (45.70%). Interaction effect showed that the highest grain yield (7.133 t ha-1), biological yield (14.60 t ha-1) and harvest index (48.86%) were found from BRRI dhan49 transplanted on 25 August. From the findings of the study it may be stated that BRRI dhan49 gave the highest grain yield and 25 August was the most suitable transplanting date. So, BRRI dhan49 transplanted on 25 August was the most suitable combination in respect of yield and yield attributes of Aman rice under tidal ecosystem. Download
