EFFECT OF DIFFERENT TRANSPLANTING DATES ON YIELD AND YIELD COMPONENTS OF RICE (Oryza sativa L.) VARIETIES
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 62
Abstract
Experiment was laid in split plot design assigning transplanting dates (25 May, 10 and 25 June) in main plot and four cultivars of rice (Jhelum, Shalimar rice-1, SKAU-341 (SR-2) and SKAU-382 (SR-3) in sub-plots. The crop planted on 25 May produced the highest yield of 74.0 and 79.0 q ha-1 during 2011 and 2012 respectively over 10 June (57.3 and 57.1 q ha-1) and 25 June (31.1 and 32.2 q ha-1). Spikelet sterility was 19.08 and 18.18, 20.21 and 20.62, 29.67 and 33.84 with 25 May, 10 June and 25 June transplanting during 2011 and 2012 respectively. Yield attributes like grains panicle-1, spikelet’s panicle-1 and test weight were recorded highest with 25 May transplanting and lowest in 25 June transplanting. Variety Jhelum recorded highest grain yields. The superiority of variety Jhelum over Shalimar rice-1, SKAU-341 and SKAU-382 was 3.9, 9.1 and 15.9 per cent, respectively during 2011 and corresponding values for year 2012 were 1.7, 8.5 and 14.7 per cent, respectively.
