EFFECT OF PLANT SPACING ON THE YIELD AND QUALITY OF TRANSPLANTED HYBRID RICE

Thakar Singh, Jashanjot Kaur and Charanpreet Singh

Abstract

A field experiment on transplanted rice was laid out in a Randomized Block Design with nine treatments, i.e., two hybrids (SVH 005 & SVH 026) and a variety, PR 115 in combination with three spacing 20 x 10 cm, 20 x 15 cm and 20 x 20 cm. The results showed that grain was significantly influenced by different treatment combinations during 2011 but, effect was not significant during 2012. In 2011, highest grain yield of 71.9 was recorded in hybrid SVH 005 transplanted at 20 x 15 cm and in 2012, hybrid SVH 005 transplanted at 20 x 10 cm recorded highest grain yield of 83.2 q/ha. Highest average brown rice recovery was recorded in hybrid SVH 005 (81.3 and 84.5 %) when transplanted at 20 x 20 cm spacing during both the years. Maximum head rice recovery of 56.2% in hybrid SVH 026 and 64.2 % in hybrid SVH 005 was recorded during 2011 and 2012, respectively when both transplanted at 20x 20 cm spacing.
