Resumo: With the objective of evaluating cowpea (Vigna unguiculata (L.) Walp.) cultivars regarding their agronomic characteristics, seed quality and levels of competition with annual cotton (Gossypium hirsutum L., r. latifolium) in an intercropping production system, an experiment was carried out at Gurinhém, PB, Brazil, in 1983. Twelve cultivars of cowpea with different growth and fruiting characteristics were used in this experiment. Two rows of cowpea were planted between rows of cotton. The cowpeas were planted 35 cm (leaving five plants per meter of row) from the adjoining cotton rows with a 30 cm spacing between the two rows of cowpea. Cotton was grown in rows 1,0 m x 0,20 m apart. Only three cultivars of cowpea (Epace 6, 40 days and CNC x 105-5E) did not significantly reduce the yield of the annual cotton indicating that these cowpea cultivars are well adapted to an intercropping system with annual cotton. The twelve cultivars of cowpeas showed no statistical difference in yield grain and had an average of 489 kg/ha.

Walp.) com relação às características de produção, qualidade de grão e força de competição no consorciamento com o algodoeiro herbáceo (Gossypium hirsutum L., r. latifolium Hutch.), um experimento foi realizado no município de Gurinhém, Paraíba, em 1983. Testaram-se doze cultivares de caupi de hábitos de crescimento e ciclos diferentes, numa modalidade de consórcio em que se utilizaram fileiras duplas da leguminosa, espaçadas entre si de 0,30 cm e distanciadas das fileiras de algodão herbáceo de 0,35 cm, com uma densidade de cinco plantas por metro de fileira, objetivando maior pressão de competição do caupi sobre a malvácea. O algodão foi plantado no espaçamento de 1,0 m x 0,2 m. Apenas três cultivares de caupi (Epace 6, 40 dias e CNC x 105 - 5E) não reduziram significativamente o rendimento do algodão, mostrando sua melhor adaptação ao consórcio com o algodão herbáceo. As doze cultivares de caupi não diferiram entre si com relação à produtividade de grão, com uma média de 489 kg/ha.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBeltrão, Napoleão E. de M.Santana, João Cecílio F. deCrisóstomo, João R.Araújo, João P.
