MECHANIZATION OF SUGAR CROPS TRANSPLANTING

[New technologies and workers' health: mechanization of sugar cane harvesting].

In the context of reorganization of production in the sugar and alcohol industry, mechanization of sugar cane harvesting has been justified as a protective measure for the environment and workers. This article focuses on the consequences of organization of work in mechanization of sugar cane harvesting with regard to the harvester operators' health. Based on data gathered through interviews and...

Effect of Plant Age and Transplanting Damage on Sugar Beets infected by Heterodera schachtii.

Sugar beet (Beta vulgaris L. cv. Monogerm C.S.F. 1971) seeds sown into Vineland fine sandy loam, infested with 15,500 H. schachtii juveniles/pot, showed little growth during an 11-week test in the greenhouse. Seedlings transplanted at 2, 4, and 6 weeks of age had 32, 30, and 31% less top weight and 71, 68, and 59% less root weight, respectively, compared to controls grown in nematode-free soil....

The Mechanization of Mathematics

The mechanization of mathematics refers to the use of computers to find, or to help find, mathematical proofs. Turing showed that a complete reduction of mathematics to computation is not possible, but nevertheless the art and science of automated deduction has made progress. This paper describes some of the history and surveys the state of the art.

Transplanting Against Histocompatibility Barriers

Tree Transplanting and Establishment

Many aspects of transplanting change over time. Modern equipment has made it possible to transplant larger trees with "soil balls" more affordably. Containerized production has grown in popularity for many reasons, including the ability to plant in any season. One thing remains the same-plants must quickly establish or reestablish a normal, spreading root system on the new site to minimize susc...
