Effect of age of seedling and plant spacing on yield and attributing traits of rice varieties under SRI method of rice cultivation

Abstract

A field experiment was conducted at Instructional Farm of Krishi Vigyan Kendra, Masodha Faizabad to evaluate the influence of age of seedling and planting geometry on yield and attributing traits of rice varieties under system of rice intensification (SRI) method of crop establishment during kharif 2012 and 2013. The experimental material was consist of the popular rice varieties/ hybrid viz. NDR 359, Sarjoo-52 & Arize 6444, three different planting geometries viz. 20 cm × 20 cm, 25 cm × 25 cm & 30 cm × 30 cm between hills and rows and three age of seedlings viz. 8, 10 & 12 days. Planting of 12 days age seedling along with the plant geometry of 25 X 25 cm produced higher grain yield in the both years of the study. The optimum level of plant population coupled with better yield attributing traits might have resulted in higher grain yield with 25 x 25 cm spacing. Among tested rice varieties Sarjoo-52 was found most suitable for SRI method of rice cultivation
