Intra raw spacing and weed management on growth and yield attributes in cotton under South Gujarat condition

Abstract

Field experiments were conducted at of Instructional Farm, Navsari Agricultural University, Navsari during kharif and summer seasons of 2010 -11 and 2011-12 to study the Effect of intra raw pacing and weed management in cotton and its residual effect on succeeding summer green gram under South Gujarat condition. Various growth and yield attributing characters of cotton were significantly affected due to different levels of spacing and weed management practices. Wider spacing of 120 x 60 cm (S3) gave higher values of all growth and yield parameters followed by S 2. The spacing level at 120 x 60 cm (S3) and 120 x 45 cm (S2) increased the seed cotton yield and stalk yield. Likewise weed free (W 4) tended to give highest seed cotton yield and stalk yield, comparable yields were obtained with application of pendimethalin @ 1.0 kg/ha pre emergence + hand weeding in at 30 and 60 DAS.
