“EFECTO DEL COMPOST DE TORTA Y CASCARA DE PIÑÓN (Jatropha curcas L.) SOBRE EL DESARROLLO Y COMPORTAMIENTO PRODUCTIVO DE FRÉJOL CAUPÍ (Vigna unguiculata Walp.)”, EN DOS TIPOS DE SUELO.

Abstract

THE PHYSIC NUT EXTRACTION PROCESS GENERATES RESIDUES SUCH AS SHELLS AND CAKE THAT CONTAIN MACRO AND MICRONUTRIENTS WITH GREAT POTENTIAL FOR AGRICULTURE. THEREFORE, THE MAIN OBJECTIVE OF THIS RESEARCH WAS TO EVALUATE THE EFFECT OF CAKE AND PHYSIC NUT COMPOST (JATROPHA CURCAS L.) ON THE DEVELOPMENT AND PRODUCTIVE BEHAVIOR OF COWPEA (VIGNA UNGUICULATA W.). ”, IN TWO TYPES OF SOIL. TWO TRIALS WERE CONDUCTED UNDER CONDITIONS OF UMBRACLE IN THE EXPERIMENTAL STATION LA TEODOMIRA, BELONGING TO THE FACULTY OF AGRONOMIC ENGINEERING OF THE TECHNICAL UNIVERSITY OF MANABÍ. IN THE FIRST TRIAL, FOUR TYPES OF COMPOST WERE MADE WITH BY-PRODUCTS FROM THE EXTRACTION OF PHYSIC NUT OIL, WHICH ARE THE CAKE AND SHELL WHOSE COMPOSITION, CONSISTING OF THE FOLLOWING TREATMENTS: 75% SHELL + 25% CAKE, 50% SHELL + 50% CAKE , SHELL 25% + 75% CAKE, CAKE 100%, THROUGH A COMPLETELY RANDOM DESIGN. IN TRIAL 2, THE EFFECT OF CAKE AND PINE NUTS COMPOST ON THE DEVELOPMENT AND PRODUCTIVE BEHAVIOR OF COWPEA BEANS IN TWO TYPES OF SOIL WAS DETERMINED, THE VEGETATIVE MATERIAL USED WAS THE COWPEA BEAN OF THE INIAP VARIETY - 463.
