Research Project: Multiplication of Long Duration Pigeon Pea Seed

Location: Forage and Livestock Production Unit

2013 Annual Report


1a.Objectives (from AD-416):
The objective of this research project is to multiply bushy type long duration pigeon pea seed ICPL 20092 for grazing trail in the southern Great Plains.


1b.Approach (from AD-416):
Long duration bushy type pigeon pea seed ICPL 20092 developed by International Crop Research Institute for Semi-Arid Tropics (ICRISAT) will be used to multiply the seed. Due to its long duration, this cultivar will not produce seed in the southern Great Plains. At the time of flowering, freezing temperatures in the southern Great Plains will damage the crop, resulting in no seed production. ICPL 20092 seed will be shipped to the University of Puerto Rico for seed multiplication. The multiplied seed will be seeded in larger plots (0.5 to 0.75 ha) to conduct grazing trials by cattle at the USDA-ARS, Grazinglands Research Laboratory, El Reno, Oklahoma.


3.Progress Report:

Long duration bushy type pigeon pea seed ICPL90092 developed by International Research Institute for Semi-Arid Tropics (ICRISAT) will be used to multiply the seed. Due to its long duration, this cultivar will not produce seed in the southern Great Plains. At the time of flowering, freezing temperatures in the southern Great Plains will damage the crop, resulting in no seed production. ICPL 90092 seed will be shipped to the University of Puerto Rico for seed multiplication. The multiplied seed will be seeded in larger plots (0.5 to 0.75 Ha) to conduct grazing trials at the USDA-ARS, Grazinglands Research Laboratory, El Reno, Oklahoma. Seed multiplication during 2012 growing season was not successful due to low germination. New seed was obtained from ICRISAT in 2012, and sent to University of Puerto Rico. Following year seed multiplication was successful and produced around 25 kg of seed. Seed multiplication continued to produce more seed, enough to conduct grazing trial.
