Ibrahim, I.A.
This study was carried out at Plant Production Department, Faculty of Agriculture (Saba Basha), Alexandria University, Egypt, during 2008/2009 season to compare three different roller ginning stands with five seed-cotton levels and investigate their effect on ginning efficiency, lint grade and fiber properties. Five seed-cotton levels; namely, Good to Fully Good (G/FG), G + 1K, Good (G), G - 1/4 and Fully Good Fair to Good (FGF/G) were used, belonged to one commercial Egyptian extra long staple cotton variety; namely, Giza 88. Three roller ginning stands were used in this study; i.e., McCarthy, Turkey single roller and Indian double roller. The obtained results clarified that the Indian double roller gin stand surpassed the other two gin stands and gave the highest gin stand capacity (kg/inch/hr), ginning out-turn (%) and lint grade. Concerning fiber properties, Indian double roller gin stand produced the lowest values of fiber elongation, maturity, reflectance degree percentages, degree of yellowness, uniformity index and the shortest mean length fibers. Likewise, the highest mean values of gin stand capacity, ginning out-turn, lint grade, micronaire value, fiber elongation (%) and reflectance degree (Rd %) were obtained from the highest seed-cotton level, Good to Fully Good (G/FG).
