CULTIVO DO FEIJÃO-CAUPI (Vigna unguiculata (L.) Walp) SUBMETIDO À ADUBAÇÃO ORGÂNICA EM CONSÓRCIO COM PALMA FORRAGEIRA NO SEMIÁRIDO PARAIBANO

Abstract

Cowpea, Vigna unguiculata (L.) Walp, is a culture well adapted to the North and Northeast of the country, presenting a social and economic relevance, mainly due to its nutritional value, income generation and tolerance culture to the consortium. This study aimed to evaluate the efficiency of organic fertilizer in cultivation of cowpea intercropped with forage palm cactus in the municipality of Itaporanga, backlands of Paraiba. Cowpea was cultivated in dryland, using native seeds, sown in consortium with forage cactus palm variety of Elephant Ear, which was planted in double rows in the spacing of 2 X 0.5 X 0.5 m. Between the double rows of palm were planted three rows of beans in the spacing of 0.5 x 0.2m. The experimental design was a randomized complete block design with four (4) treatments of four (4) levels of bovine manure (T1 = 0.0, T2 = 10.0, T3 = 20.0, T4 = 30.0 ton / ha) and four (4) repetitions.Treatments were applied on plots of 12 m2 area. Data were submitted to analysis of variance (F test) and the averages to the Scott-Knott test at 5% of probability. The variables analyzed were plant height, stem diameter, number of leaves and production. The growth variables were increased early in the development of culture. Moreover, there was increased production with increasing levels of bovine manure.
