Show J More Cultivation j Eliminates Weeds - Because of the great expense '', incurred in the use of chemicals j lor control of weeds, less expensive methods o fweed control need further fur-ther investigation, Dr. R. J. Evans, professor of Agronomy, Utah State Agricultural college, declares. He states that some rapid-growing crops which produce a dense foliage may be able to compete ' successfully with most weeds, and j there are also many intensively 1 cultivated crops which could be used in a weed control program : by careful farmers. "Some farmers, j for example, have reported that the intensive cultivation practiced to celery production has produced ', almost complete kills of morning ' toy and whitetop," he adds. Dr. Evans describes two field speriments which have been conducted con-ducted by the Utah Experiment s Station to study cropping practices ! that might aid in weed control, "The most striking result of these studies is the good weed kills obtained ob-tained by growing sugar beets, "KM, sorgham and soybeans," emphasizes the agronomist, who ais that "many farmers fail with such a program, however, because '"ey do not clean the weeds out thoroughly enough from around the crop plants, or they miss a cultivation or two.' Kills obtained with barley and soytjeans are of perhaps more interest in-terest than those resulting from I cultivated-.crops,, says Dr. Evans. "With these crops, the land Tas plowed early in the spring. set the weeds back and gave 'he barley a chance to get well established before the whitetop emerged. The barley then shaded 'he weeds and kept them fairly "ell unr!er controi until the. crop tnatured. FoUo.wing the harvest, the land was clean cultivated for 'he remainder of the summer and fall. ' ''Soybeans are planted much later than barley, - so with this it was posibie to clean cult. Ivate for a period during the ng. The soybeans grow rapidly flUring the warm weather and act w excellent smother crop for the Te on through the fall. While 'tans have not been very suc-ful suc-ful as a seed crop in Utah, e farmers might well consider jjng them for hay on land Nested- with whitetop." |
