Effects of Mechanical Transplanting Technique on Productivity for G86 Cotton Variety

Effect of Transplanting Cotton on Growth, Earliness, Productivity and Fiber Quality As Compared with Early and Late Direct Seeding Under Spraying with Pix تأثير شتل القطن على النمو والتبکير و الإنتاجية وجودة التيلة مقارنة بالزراعة المبکرة والمتأخرة بالبذرة تحت الرش الورقى بالبکس

“…Singh et al (2013) revealed that raising crop by growing seedlings in the nursery and later transplanting them at an appropriate time has an exploitable potential. Hassan et al (2015) found that transplanting cotton seedlings can significantly increase yield and improve crop establishment by eliminating effects of harmful environmental before transplanting. Mehrabadi (2017) reported that transplanting led to a nonsignificant increase (9%) in yield, compared to seed sowing.…”

“…On the other hand, other workers concluded that transplanting produced lower yields than either early or late direct seed sowing (Abdel-Ghaffar et al, 1976;Ghaly et al, 1987 andRadwan, 1988). Hassan et al (2015) reported that sowing date respect an important part in productivity and properties of Egyptian cotton. Late sowing in May has an adverse effect on yield and its components.…”

“…This technique allows the farmers to harvest winter crop in proper time, take more than two cuts of clover before transplanting cotton in May and avoid damage of reproductive parts by late season insect pest attack. The advantages of starting germination and seedling growth in nursery bed (trays) and permanent field were summarized by (Seif El Nasr et al, 1996;Dong et al, 2007 andHassan et al, 2015) as following ; 1-Greater pests, climate and weed control thus saving labor on hoeing and weeding, 2-Rapid seed germination, 3-Fewer water, 4-Fewer seeds used by reducing seeding rates, 5-Save labor on thinning, 6-Avoid the risk of heat stress during May on the seedlings emergence, 7-Improving the reproductivevegetative ratio during the season through extending the period of reproductive development, 8-Reduces the use of fertilizer, 9-Shorten the growing season to reduce the cost of production and to cultivate the cotton after the complete season of winter crops (wheat, clover and bean) in the same space, 10-Providing cotton seed and maintain the purity of the product and the production of new cotton genotypes and 11-Reduce the proportion of early and late injuries by eliminating harmful environmental effects before transplanting.…”
