Abstract
Six experimental pigeonpea (Cajanus cajan (L.) Millsp.) lines were evaluated during 1992 for their agronomic performance at Petersburg, Virginia under the New Crop Development Program of Virginia State University. The germination and stand establishment of indeterminate lines was poor due to low seed quality. The final seed yield varied from 349 to 2042 kg/ha with determinate types yielding significantly higher than indeterminate types. The experimental line GA#2 produced the highest yield. The protein content in mature seeds, harvested 175 days after planting (DAP), varied from 17.0 to 18.5 percent whereas the oil content varied from 1.7 to 2.3 percent. The seed yield was positively correlated with harvest index, seeds/pod, and seed weight. At 130 DAP, the 3 determinate lines yielded more than 10 metric tons of green beans per hectare (70 percent moisture). The protein and oil content of immature seeds from these pods varied from 18.1 to 21.2 and 2.1 to 2.2 percent, respectively. Pigeonpea, depending upon the variety, can also be used as an ornamental or vegetable plant in home gardens. The results of these experiments were quite encouraging.
