Research Project: PIGEONPEA CULTIVARS FOR SUSTAINABLE CEREAL-LEGUME CROPPING SYSTEM IN THE U.S. SOUTHERN PLAINS

Location: Forage and Livestock Production Unit

2009 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.


3.Progress Report

Tropical legumes offer potential forage and grain that can be grown during the summer fallow period in the continuous winter wheat production system typical of the southern Great Plains region. Earlier research demonstrated that pigeon pea is drought tolerant and produces abundant quantities of high-quality forage as well as grain in Oklahoma. Pigeon pea grain has high-quality protein, which can be utilized as both human and animal feed. Pigeon pea grain has the potential to replace high-priced supplemental protein concentration for cattle. Pigeon pea hybrid germplasm previously supplied by ICRISAT provided a slightly longer growing season and a delayed seed setting, which resulted in lower seed yield. In 2009, ICRISAT provided 3 short-duration hybrid seed cultivars. The new hybrid seed was seeded along with the local cultivar. ICRISAT continues to provide information and assistance in developing new cultivars suitable for the southern Great Plains region. The ADODR monitors the activities of this agreement through meetings and conference calls.
