Abstract:
A study was conducted to evaluate the effect of establishment methods and microclimate on growth and yield of rice varieties (Oryza sativa L.) was carried out during kharif season 2016 at the research farm of College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar. It was laid out in a Split-Split Plot design, replicated thrice with three establishment methods (M1- Direct Seeding, M2-Unpuddled transplanting, and M3-Puddled transplanting) as main plot treatments, two dates of sowing (D1-17th June and D2-26th June) as sub plots and two varieties (V1-Naveen and V2-Pooja) as Sub-Sub plot treatments. The leaf area index (LAI) increased progressively upto panicle initiation stage there after decreased gradually and influenced by different rice establishment methods, dates of sowing and the rice cultivars. All the yield attributing characters i.e. number of panicles m-2, number of grains panicle-1and 1000 grain weight were more in plants planted after puddling than the unpuddled transplanting and direct seeding. The treatment also produced maximum grain yield (3879 kg ha-1) with HI value of (61.52).
