Rendimento de variedades tradicionais de feijão-caupi do estado do Acre em resposta a adubação orgânica com húmus de minhoca Vermelha da Califórnia Lumbricus rubellus

The fertilization of planting is one of the factors that determine a bountiful harvest and growthfor the bean. Seeking a viable, efficient and recyclable in effect, the present research aimedto evaluate the performance of seven genotypes of cowpea in the state of Acre in function oforganic fertilizer. Depending on the organic fertilizer, planting in the grooves was made withhumus of the earthworm Lumbricus rubellus California Red, using heirloom seeds. The experimentaldesign was of randomized blocks with seven treatments and three repetitions, eachexperimental unit represented a portion of three lines with 5 m long spaced out between themselvesin every meter. The variables analyzed in response to earthworm humus were the plantheight (cm), grain yield (kg ha-1) and length of 25 pods (cm). For the grain yield (kg ha-1) andlength of 25 pods (cm) the variety of Costela-de-Vaca obtained gave greater results whereasfor plant height it was the variety Ceara Mercado.
