...check insect pests by tricks of cultivation. They import the ancient enemies of invading foreign insects and foster the resident enemies of native pests. They are developing bacterial diseases to spread pestilence among insect populations. Because these tactics alone are seldom enough to protect the tender plants of modern, high-yield farms, the use of insecticides is economically necessary. Tests run by the Department of Agriculture show that failure to use pesticides would cost a major part of many crops; a 20-year study proved that cotton yields would be cut by 40%. Production of many kinds of fruit...
...agricultural hormones that have produced higher-yielding rubber trees. By sharing his developments with the official Malayan rubber research agen cy and, along with other rubber planters, helping to finance it, he is now sparking the government's drive to help hundreds of small growers replant with high-yield trees. Last year Sir John's trees produced up to 1,000 Ibs. of rubber per acre (v. 400 Ibs. for older varieties) and brought Guthrie a $10.4 million pretax profit on sales of $31 million...

Best performers were the ultraconservative funds that attempt to ensure a steady dividend income by concentrating their holdings in bonds and high-yield stocks. Thus Boston's Incorporated Income Fund fell only 9.4%, and the K-1 fund operated by the Keystone Custodian Fund dropped only...
...rays. This rough treatment kills the delicate female genetic material but does no apparent harm to other parts of the eggs. Then Dr. Astaurov fertilizes the eggs with male sperm that has not been irradiated. When the embryos develop, they are free of female influence; they all grow into high-yield male silkworms...
...years in Tha Pra, Alex Johnson has introduced the country's first silage system, taught sanitation, farm management, building construction and irrigation, brought high-yield corn (50 bu. per acre) from Indonesia, improved pasture and foliage, showed his charges how to use commercial fertilizer, planted grain and sweet sorghum, introduced the Velvet bean and the cowpea (for soil improvement). In his own acre-plus garden he demonstrated to once dubious Thailanders that pineapples and bananas can be grown well in poor soil, even cultivated tomatoes, collards, okra, eggplant, yellow squash, sweet corn and lettuce...
