| dc.description.abstract | Experiments were conducted from 1976 to 1978 at the Arlington Experimental Farm, Arlington, Wisconsin, to study the effect of planting dates, row widths and herbicide treatments on 'Hodgson1 and 'Wells' soybeans. Additional studies were conducted at Janesville, Wisconsin, in 1976 and 1978 "but one date of planting was used. Yield decreased with delayed planting. 'Hodgson' consistently outyielded 'Wells'. Soybeans planted in 10-inch rows yielded more than those in either the 7- or 30-inch rows. Except at Arlington in 1976, a postemergence application of bentazon did not increase yield significantly. In 1978 a John Deere planter was compared with a Tye soybean drill and an IHC grain drill to study their effect on soybeans planted in 7-ยป 10-, 20- and 30-inch rows. For most soybean characteristics studied, the Tye soybean drill was not different from the John Deere planter but was superior to the IHC grain drill. The effect of fungicides on seed quality was studied in 1978. 'Evans', 'Hodgson', 'Wells' and 'Beeson' soybeans were used in Experiment 1.where different rates of benomyl were compared and only 'Wells' was used in Experiments 2, 3 and 4 in which benomyl and thiabendazole were compared. Also the effect of cultural practices mentioned above were studied. 'Evans' yielded highest but was the most susceptible to Maporthe and Alternaria. Susceptibility decreased with lateness in maturity. The best disease control was obtained when 1/2+1/2 Ib/a of benomyl was applied at RJ and R6 or 1+1 Ib/a applied at the same times. Little response to fungicide treatments was found at Arlington. Seed infection decreased with delayed planting. Row width and herbicide treatments did not affect seed quality. | en_US |
