Preliminary behavior studies of 21 mung bean cultivars at ltaguaí, RJ, Brazil

Abstract

Twenty-one cultivars of mung bean, Vigna radiata (L.) Wilczek, originated from Taiwan, were studied at the experimental station - UAPNP Biologia do Solo/EMBRAPA, Seropédica, ltaguaí, Rio de Janeiro State, Brazil, in a Red-yellow Podzolic Soil, ltaguaí serie, in the dry season. Cultivars grain yields were influenced directly by nodulation, total plant N and, principally, by seed number per pod. Cultivars V 3476 (Philippines), CV 2764A, VC 2755A, and VC 1000C (Taiwan) yielded more than 1,700 kg/ha and presented better agronomical characteristics than the other cultivars. The majority of the cultivars showed erect growth habit, good plant height, good nodulation, and uniform plant maturity. They showed possibility of two pod harvesting for grain production.
