Investigations involving four cultivation treatments were conducted at the Utah State University Greenville Experimental Farm to determine the effect of these treatments on yields of beans and sweet corn. The effects of the different treatments on soil water content, soil temperature, and weed control in beans and corn were investigated. The effect of cultivation on the degree of root rot infection and the effect of different planting dates were also investigated in the bean study.
The pre-emergence treatment (ridged just before the plants emerge) produced a 48 percent greater bean yield and a 40 percent greater corn yield than the control treatment (no cultivation). The planting-ridge treatment (ridged at planting time) produced 21 percent greater bean yield than the control treatment. The post-emergence treatment (cultivated after the plants emerged) yielded 10 percent more beans and 20 percent more corn than the control treatment. The second and third planting dates produced 16 and 42 percent, respectively, greater bean yields than the first planting date. The pre-emergence treatment had a higher soil water content and soil temperature than the other methods in both the beans and corn. The pre-emergence treatment had 50 percent less root rot infection than the control treatment. The planting-ridge treatment had 30 percent less root infection than the control and the post-emergence root infection was 17 percent less than the control. The root rot infection in the second and third plantings was 15 and 32 percent, respectively, less than the first planting. The order of best weed control was: pre-emergence, planting-ridge, and post-emergence. The pre-emergence treatment produced the most favorable results in all aspects of the study.
