Evaluación de los indicadores morfo fisiológicos y el rendimiento del frijol caupí (Vigna unguiculata) con el uso de dos alternativas orgánicas y microorganismos eficientes

Abstract

Cowpea bean is a legume with high nutritional value. In Ecuador, in 2021, were cultivated 29,539 ha with a production of 17,717.21 t. In organic fertilization, the main fertilizers used in crops are usually composts and manures, which favor the growth and development of the plant and microorganisms, and vermicompost leachates are Biostimulants that constitute alternatives for sustainable agricultural production. The main objective of this research was to evaluate the morphological and physiological indicators and yield of cowpea using vermicompost leachate, decomposed bovine manure and efficient microorganisms, in an experiment with a completely randomized block design (DBCA) with three repetitions and seven more treatments. the witness. Four applications were made every 15 days after germination until harvest. For the analysis of variance, the TUKEY test at 5% was used. It was demonstrated that the use of bovine manure, leachate from vermicompost and efficient microorganisms induced that the magnitudes of the morphological, physiological and productive indicators evaluated reached values equal to or higher than those obtained with chemical fertilization based on nitrogen, phosphorus and potassium, which shows the potential of these biostimulants in the crop and that the vermicompost treatment of 3 t. ha-1 induced a significant effect, compared to efficient microorganisms, leachates and NPK fertilization on the number and weight of pods and grains per plant, as well as the estimated yield in Kg ha-1 in the bean crop. cowpea
