Abstract
Yield trials of pigeonpea cultivars grouped into early, medium, and late maturity were harvested for grain at maturity by ratooning (cutting the plants off above the branching level). Plant survival after ratooning and regrowth varied among cultivars in all tests. First harvest of early cultivars was affected by high pod-borer damage, and the second grain crop was equal to the first on average; medium cultivars produced a second crop approximately 50% of the first, and late cultivars produced no grain after the first harvest. Indications of cultivar differences for survival and regeneration after ratooning suggest the possibility of effective selection for these characteristics. Results presented are from deep black soils in a year of unusually heavy rainfall; the authors recognize the limitations of the data, but believe that the potential for taking a second crop merits further investigation.
