Produtividade e morfologia de acessos de caupi, em Mossoró, RN

Abstract: O objetivo deste trabalho foi avaliar a produtividade e caracterizar a morfologia de dez acessos de caupi [Vigna unguiculata (L.) Walp.], nas condições edafoclimáticas do município de Mossoró, RN. Dez acessos (Amapá, BRS Potiguar, Canapu, Casca-de-seda, Coruja, Costela-de-vaca, João-vieira, Pingo-de-ouro, Rabo-de-peba e Sempre-verde) foram avaliados em experimento de campo, de agosto/2006 a junho/2007, em Mossoró. Verificou-se que todos os genótipos de caupi apresentaram hábito de crescimento indeterminado e s… Show more

“…Similar results to those of the present study were previously reported for W100G of cowpea. Torres et al (2008) evaluated 10 cowpea accessions in the soil-climatic conditions of Mossoró, RN, and reported that the average W100G ranged from 15.86 g (Pingo-de-ouro) to 23.47 g (Costelade-vaca). Bertini et al (2009) evaluated 16 cowpea accessions of the germplasm bank of Universidade Federal do Ceará, and found a variation in grain yield, that is, 35.65-328.15 g. The YD was highest for accession CE-871, and the other accessions with high YD were CE-79 (312.29 g), CE-93 (292.73 g), and CE-873 (323.03 g).…”

“…Cowpea crops have great economical and nutritional importance for the agricultural development in this region. It is a staple food in the diet of the poorest populations, with a nutritional function by the supplying their nutrient needs (TORRES et al, 2008). This crop can be grown in low fertility soils, adapt to high temperatures and drought conditions, and associate with bacteria of the genus Bradyrhizobium, generating biological N fixation by symbiosis (ASIWE, 2009).…”

“…Variedades crioulas de feijão-caupi, apresentam uma ampla variabilidade genética, e alguns trabalhos têm sido realizados com o objetivo de caracterizar e conservar esses materiais, podendo serem utilizados dessa maneira em programas de melhoramento genético dessa cultura (OLIVEIRA et al, 2011;TOLERA et al, 2008). Torres et al, (2008) avaliando dez genótipos de feijão-caupi oriundos do município de Mossoró, conseguiram indicar como melhor alternativa para o agricultor(a) o acesso Amapá, por ser o mais precoce, possuir o maior número de vagens por planta e por ter apresentado a maior produtividade em relação aos demais genótipos análisados.…”
