STUDY OF DIFFERENT RETRANSPLANTING DATES ON YIELD AND NUTRIENT CONTENT OF LATE AMAN RICE (BR 22)

Abstract

An experiment was carried out at the experimental field of Sher-e-Bangla Agricultural University, Dhaka during August’08 to January’09 to evaluate the effect of retransplanting dates (16 September, 26 September, 6 October and 16 October) on yield of T. Aman Rice cv. BR 22 (kiron). The retransplanting dates were assigned in the plots in a Randomized Complete Block Design (RCBD) with 4 replications. The effect of transplanting and retransplanting dates were significant in respect to yield attributing characters like plant height, effective tillers/hill, ineffective tillers/hill, grains/panicle, sterile grains/panicle and thousand seed weight and also the nutrient uptake of rice plant. The first Transplanting on 16 th September have significantly highest grain yield (4.725 t/ha) whereas the lowest yield (3.375t/ha) was found in the last retransplanting on 16 October.
