Performance of six rice cultivars under direct wet seeded conditions of Dera Ismail Khan [Pakistan]

An experiment was conducted to evaluate the performance of 6 rice cultivars. The variety KS-282 produced the highest number of tillers per plants as compared to IR-6, Swat-I, JP-5, Swat-II, and DR-83, KS-282 was also the tallest among the cultivars, while the remaining cultivars were almost of the same height. Number of panicles/plant and spikelets/panicle were also the highest in KS-282. 1000-grain weight was also the highest in KS-282. Moreover, cultivar KS-282 outyielded all the cultivars in straw and paddy yield (12.15 and 6.31 t ha-1, respectively). The highest partitioning of the assimilates towards the economic yield (37.43 %) was also recorded in the cultivar KS-282, while other cultivars possessed almost the same harvest index. The maximum normal kernels (%) were also observed in the cultivar KS-282 with a minimum sterility percentage, as compared to other cultivars, included in the trial.
