Potential of traditional varieties of cowpea in the state of Acre in response to organic fertilization with California Red earthworm humus Lumbricus rubellus

Abstract

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