ABSTRACT

Field experiment was conducted in lowland situation at Jorhat (Assam) during late kharif seasons of 2012 and 2013 to study the performance of double transplanted rice under 3 planting dates (10, 20 and 30 September) with 2 spacings (15 cm x 10 cm and 20 cm x 10 cm) and 3 seedling rates (1, 2 and 3 seedlings/hill). Results revealed that grain and straw yields as well as all the yield attributes decreased significantly and consistently with delaying the planting dates from 10 September to 30 September during both the years. On an average, the reduction in grain and straw yields was 81.5 and 30.1 per cent, respectively. Both the spacings could not influence the yield and yield attributes during both years but had higher values in wider spacing of 20 cm x 10 cm over the narrower spacing of 15 cm x 10 cm. Planting of 3 seedlings/hill produced the highest grain and straw yields. The net return and benefit-cost ratio were recorded highest on 10 September planting with the use of 3 seedlings/hill.
