A preliminary field assessment of mungbean (Vigna radiata L. Wilczek) yield in the rain forest zone of southeastern Nigeria.

摘要

Four mung bean accessions from the Asian Vegetable Research and Development Centre (AVRDC) were grown in a randomized complete block design in eight replicates from September to November 2003. Results showed a significant difference in the yield of the varieties with VC 6372 (45-8-1) producing the highest seed yield of 0.53 t/ha. This was followed by NM 92, 0.48 t/ha; NM 94, 0.40 t/ha; and VC 1163 with 0.37 t/ha. The variety, VC 6372 (45-8-1), also formed good agronomic characters. None of the varieties were affected by Cercospora leaf spot disease. Some insects commonly associated with legumes in the region were observed at various growth stages. The conclusion is that the new pulse crop has demonstrated substantial promises in growth and yield characteristics to warrant further trials in other seasons and locations in the humid forest zone of southeastern Nigeria.
