Impact of Cotton Leaf-Hairs and Whitefly Populations on Yields in the Lower Rio Grande Valley.

Infestations of sweetpotato whiteflies (Bemisia tabaci) cause significant reductions in cotton yields. Growing tests conducted during 1994 indicated a potential loss of more than 20 pounds of lint for each immature whitefly infesting the cotton from late May to early July. Furthermore, cottons with greater leaf hair densities encourage hi..

World Cotton Production Outlook for 1995-1996.

In July 1995, USDA Foreign Agricultural Service analysts projected world cotton production for the marketing year 1995-1996 at 90.8 milion bales, up 1.8 million from the May 1995 projection. Problems that had affected the 1993-1994 cotton crop continued to impact the 1994-1995 crop. In particular, unfavorable weather, plant disease, and i..

Recycling of blends containing wool

Results are presented which represent the first stage in the quantitative characterization of the rag pulling process in relation to wool blend waste. The mechanical induces obtained: power applied, work of opening, and opening efficiency, are determined by the material structure and the rate of throughput. The effort required to open up ..
