Abstract
The development of mechanical cotton harvesting can cause significant changes in the conventional cotton production process from the point of planting pattern. A study was conducted to determine the effects of narrow row and conventional row cotton production systems on cotton picker and stripper performance under farmer's field conditions in 2022. The results showed that cotton stripper application in narrow row system reduced effective field capacity by 26.2% as compared to cotton picker. The wide row cotton production system had a lower percentage of ground losses and total losses (6.7 and 11.1% respectively) as compared to narrow row systems, although difference in seed cotton loss was not significant among cotton production systems. The findings showed that application of narrow row system increased the seed cotton yield by 10.5 % compared to the wide row system. The results revealed that different cotton harvesting systems had no effect on characteristics of fiber quality. However, results indicate that, application of narrow row cotton production system with stripper harvester is more effect to improve seed cotton yield compared to the wide row cotton production system in cotton-cultivated regions of the south part of Fars province and other areas with the similar ecological conditions.
