Evaluation of Rice Varieties in Kharif Season.

Abstract

Eight varieties of rice (DR-92, JR 16-15-1-1/Geeta, IR-28, IR-30. Lalita/Cauvery. R-2369/Madhuri, RWR 5-4 and Kranti) were grown under low and high levels of N (60 and 120 Kg/ha) in a randomised-block design with three replications in Kharif, 1978 and 1979. Number of productive tillers per plant was the major yield-attributing character. Among the extra-early varieties, DR-92 yielding 45 q/ha was superior to JR 16-15-1-1 or Geeta, Among the early variaties, RWR 5-4 was the best. The medium duration "Kranti was unsuitable. Increasing N application increased the yield.
