Effect of sowing window on growth parameters and yield of different rice varieties in Krishna western delta

Abstract

A field experiment was conducted to evaluate the effect of different sowing dates on yield and yield components of the different rice varieties during kharif 2015 at Agricultural Research Station, Bapatla. The experiment was laid-out in split plot design with three replications. The four rice varieties viz, BPT 5204, BPT 2270, BPT 2231 and BPT 1768 were considered as main treatments and four dates of sowing like 15th July, 1st August, 15th August and 1st September were considered as sub treatments. The results revealed that BPT 2231 rice sown on 15th July proved to be the best for obtaining highest plant height, productive tillers, panicle length and grain yield (5900 kg ha-1) and straw yield (7178 kg ha-1) followed by BPT 2270 variety.
