Evaluation of Growth Performance of Some Rice Varieties in Relation to Their Economic Yield
Journal Title: Asian Research Journal of Agriculture - Year 2017, Vol 7, Issue 2
Abstract
The experiment was conducted during the period of March to August (Aus season), 2013 at the experimental farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, and Dhaka to evaluate the growth performance of some rice varieties in relation to their economic yield. The performance of BRRI hybrid dhan1, BRRI hybrid dhan2, ACI hybrid2, Jagoron and Panna1 were compared with check variety, BRRI dhan48. The experiment was laid out with Randomized Complete Block Design (RCBD) with three replications. Data were recorded on different growth parameters, grain yield, straw yield, biological yield and harvest index. The data were recorded at 30, 45, 60 and 75 days after transplanting (DAT) as well as at final harvest and obtained data were statistically analyzed for comparisons. In term of vegetative growth parameters, plant height, tiller hill-1, leaf area index, stem dry matter hill-1, leaves dry matter hill-1 and total dry matter hill-1 at different DAT, the ACI hybrid2 was superior over the check variety, BRRI dhan48 as well as BRRI hybrid dhan1 and BRRI hybrid dhan1. Highest and statistically significant grain yield (3.05 t ha-1) straw yield (4.20 t ha-1) biological yield (7.25 t ha-1) and harvest index (42.01%) was observed in ACI hybrid2 which was statistically identical with hybrid rice Jagoron and Panna. All test hybrid varieties were superior in vegetative and yield performance over inbreed BRRI dhan48 during Aus season.
