The use of agroforestry residues in the development of string bean seedlings

Abstract

The use of organic waste from agricultural activity has to be an alternative for its destination. In this sense, product alternatives are needed to be used as a substrate. Cowpea is a strategic protein source for human consumption due to its edaphoclimatic adaptability. Thus, this work evaluated the initial development of Caupi beans due to the incorporation of agroforestry residues into the soil. The parameters taken were germination rate, Germination Speed ​​Index, plant height, root length, weight of fresh and dry matter of the root and aerial part and size of the leaf area. The treatment consisting of açaí seed + soil (1: 1) promoted greater development of the aerial part and leaf area, weight of dry and fresh mass, as well as a higher germination rate for both genotypes. The use of Brazil nut shell and hedgehog is not recommended as a substrate for the production of cowpea beans.
