Summary:Integration of rice-wheat research within a systems perspective permits evaluation of potential innovations in terms of their overall impact on the crop pattern, the level at which farmers make technological choices. Time-related factors influencing system productivity included the transplanting of old rice seedlings, the late planting of wheat due to delayed rice harvest, and a prolonged turnaround period between crops. Short-duration rice varieties lead to increases in total system productivity for late planted rice; zero tillage establishment of wheat may reduce turnaround time; while wheat varieties which are high yielding over a range of plant dates increase farmer flexibility in maintaining system productivity.
