2013 Annual Report
1a.Objectives (from AD-416):
Exchange pigeonpea germplasm for sustainable cereal-legume cropping systems suitable for the southern Great Plains region.
1b.Approach (from AD-416):
Identify and exchange Pigeonpea cultivars suitable for the summer fallow period in a continuous winter wheat production system. Evaluate pigeonpeas as forage or forage/grain crop for the utilization by humans and/or livestock under the climatic conditions of the Southern Great Plains. Provide detailed climatological data for El Reno, Oklahoma, to ICRISAT.
Tropical legumes offer potential forage and grain that can be grown during summer fallow period in the continuous winter wheat production systems typical of the Southern Great Plains (SGP) region. Earlier research demonstrated that pigeon pea is drought tolerant and produces abundant quantities of high-quality forage as well as grain. A pigeon pea line (ICPL20092) has been obtained that has more leaf to stem ratio. This line is a long duration and will not produce seed in the SGP area. The seed material will be shipped to the University of Puerto Rico for seed multiplication. A non-funded research agreement is under progress. Once the seed is multiplied, it will be used to conduct a grazing study. ICRISAT continues to provide information and assistance in developing new cultivars suitable for the Southern Great Plains region.
