1996 Dry Bean Grower Survey of Pest Problems and Pesticide Use in Minnesota and North Dakota |

Crop Rotations
Northarvest respondents reported crop rotations on 71% of respondents' acres, down from 77% in 1995 but about the same as the 70% in 1994. Crop rotation was reported on 75% of respondents' acres in Minnesota and 70% in North Dakota (Table 37).
Crop rotations used by Northarvest respondents usually involved several years between dry bean crops (Table 38). The number of years since the previous dry bean crop had been grown was cited as one year by 3% of respondents, two years by 14%, three years by 32%, four years by 22%, five or more years by 11%, and never before grown in that field by 15%. More Minnesota respondents (25%) reported they had never planted dry beans in that field than did North Dakota respondents (10%). The data are similar to those for 1994 and 1995.
Wheat preceded dry beans for 59% of survey respondents, followed by barley and corn, each for 17%. Differences between states occurred, however, with wheat (68%) and barley (22%) as the most frequent preceding crop in North Dakota, and wheat (41%) and corn (39%) reported by Minnesota respondents (Table 39).
