Effects of plant spacing on growth and yield of cotton cultivar Sri Sumrong 60 grown in dry season
The objective of this experiment was to study the effects of narrow spacing on growth and yield of cotton cultivar Sri Sumrong 60. Trial was conducted at National Corn and Sorghum Research Center, Pak Chong, Nakhon Ratchasima from January to July 1996. The design of the experiment was a splitplot design with 3 replications. Main-plot treatments consisted of two between row spacings, 1.0 and 0.5 m and the sub-plots were two within row spacings of 0. 1 and 0.2 m. Results revealed that no spacing effect was found on yield and yield components of cotton. However, the row spacing of 1.0 m had trend to give approximately 10% higher seed cotton yield than of 0.5 m. And within row spacing of 0. 1 m also had trend to give 13.5% higher seed cotton yield than of 0.2 m. It is dued to higher value of the efficiency of light conversion of cotton grown in within row spacing of 0. 1 m.
