Improvement of Cotton Crop Performance by Estimating Optimum Sowing and Picking Time

Abstract

Performance of seed is determined by interactive component effect of genetics, physiological quality and the environment.

Effect of Planting and Harvesting Dates on the Physiological Characteristics of Cotton-Seed Quality

“…However, late planting date exposed cotton plant to extreme temperature and heat units that due to increase growth but gave low yield characters and decrease yield. These results are in line with Boquet et al (2003), Kamran et al(2017) and Omar et al(2018).…”

“…That might attributed to the high cotton seed quantity found during middle October, which harvesting during this times the relative humidity of field environment is suitable for seeds. So that the optimum temperature for cotton planting is from March to Aprilthat ensure plants to normal physiological phase shifting, increase resistance for insect infection and harvesting during warm and humid weather for ensuring high quantity and quality of cotton-seed (Kamran et al, 2017).Harvesting time also noted significantly importance in cotton seed quality, which cotton-seed picked in September and October with good quality and surface maximum germination potential (Deho et al, 2012).…”

“…At harvesting stage exposure bolls after maturity to humid weather may be detrimental for physiological cotton seed quality. Late harvesting date have higher moisture which speeds cotton seed deterioration that lower the germination, make seed highly sensible to mechanical damage and infected by insect pest during seed processing and storage (Jyoti andMalik, 2013 andKamran et al,2017).…”
