Growth, chlorophyll index and production of common and cowpea beans using different fertilizations

Abstract

Beans are a the major component in the Brazilian diet population, mainly in the northeast of Brazil, though yield is considered low due to the low technological content that is conducted in most producing regions, making it necessary for fertilizations to increase this feature. Considering the above, this study aimed to evaluate growth, chlorophyll index and the production of cowpea bean and common bean under different fertilizations. The experiment had been conducted in the Centre of Human, Social and Agricultural Sciences at The Federal University of Paraíba. The experimental design was a randomized block in factorial arrangement 2 × 4 with seven repetitions. The treatments consisted of two-bean varieties (Phaseolus vulgaris L. and Vigna unguiculata L.) and four fertilization (Leaf biofertilizer, organic compost made with goat manure, mineral fertilization and a without fertilizer treatment). The variables analyzed was growth, chlorophyll index and bean production. The bean cultivar Sempre Verde obtained higher growth and chlorophyll index a, b and total in relation Carioca. Fertilization with organic compost provided higher productivity of bean cultivars. The organic compost may be indicated as fertilizer alternative to the bean in the Paraíba swamp region.
