Improving rotational crop establishment options following rice

Summary

Recropping of rice stubbles to winter crops is impaired by the presence of heavy rice stubbles post harvest. Most Australian ricegrowers resort to stubble burning in order to facilitate reliable following crop establishment. We propose to evaluate a range of techniques to retain rice stubbles whilst enabling reliable establishment of the following winter crop. Inversion and surface retention will be evaluated by various means. One technique will involve a novel PTOpowered disc plough connected to a steel wheeled tractor in order to traffic and invert rice stubbles (wet or dry) whilst simultaneously seeding following crops (such as green manure or grain legumes, cereals or canola). Surface retention will be attempted using the “Happy Seeder” system ( a device currently being evaluated in India).

Objective Summary

Demonstrate the utility of a PTO powered disc plough to invert stubbles immediately post harvest whilst simultaneously seeding a following crop. Compare stubble inversion with a range of alternate stubble management techniques aimed at enhancing following crop establishment. Evaluate following crop performance when subjected to the above techniques.
