Abstract
The value of 'Pioneer 8222' sorghum in rotation with soyabean for the management of nematode problems was studied in an experimental field infested with Meloidogynearenaria and Heterodera glycines, race 4. In 1988 cultivars Braxton, Centennial, Gordon, Kirby, Leflore, Ransom, and Stonewall were planted in plots in which sorghum was grown the preceeding 2 years and also were planted in plots that had been in continuous soyabean production. Each cultivar in thetwo cropping systems either was not treated with nematicide or was treated with an at-plant application of aldicarb (41.4 g a.i./100 m of row in a 20-cm-wide band). Except for Braxton, aldicarb did not increase yield of any cultivar in the sorghum-soyabean plots; however, yield of 'Kirby' and'Leflore' were increased in the monoculture system. Yields of all cultivars were higher in the sorghum-soyabean plots than in those in monoculture. Yield increases in response to the sorghum-soyabean system compared with continuous soyabean varied from 31% for 'Kirby' to 231% for 'Stonewall'; theaverage increase in yield for all cultivars was 85%. Populations of H. glycines juveniles in soil samples taken 6 weeks before harvest were lowest in plots with 'Leflore'. In general, numbers of juveniles were lower in plots with the sorghum-soyabean rotation than in the monoculture plots. Thehighest populations of M. arenaria juveniles were associated with 'Leflore' in plots with continuous soyabean. The aldicarb treatment had no effect on end-of-season soil populations of H. glycines or M. arenaria...
