Growth and yield of rice as influenced by different planting techniques

Abstract

A field experiment was conducted at the farm of Uttar Dinajpur Krishi Vigyan Kendra, Uttar Banga Krishi Viswavidyalaya, Chopra, Uttar Dinapur, West Bengal, India to study the effect of different planting techniques on growth and yield of rice (cv. Koushalya). The results obtained for two years on tillering pattern depicted that maximum tiller number (715.7 m−2) was obtained in system of rice intensification (SRI) method at 70 days after sowing (DAS). Rice crop grown with SRI technique matures at least 4–7 days earlier than other planting methods. SRI technique produced maximum plant height (152.9 cm), moderate number of chaffy grains per panicle (25.9), maximum number of in-effective tillers (43.2 m−2), whereas, double planting technique produced least plant height (133.1 cm) as well as least number of ineffective tillers (16.0 m−2). SRI technique also out yielded all other treatments with respect to yield components, grain yield (5.6 t ha−1) and straw yield (7.6 t ha−1). However, double transplanting method recorded highest harvest Index (HI), while, it was least with SRI method. Considering all the factors, SRI method proved to be the best method as compared to other transplanting methods under study.
