´´ ABSORCIÓN DE NUTRIENTES (NPK) EN EL CULTIVO DE ARROZ (Oryza sativa L.) VARIEDAD INIAP 14´´

Abstract

THE RICE (ORYZA SATIVA L), IS CONSIDERED ONE OF THE MOST IMPORTANT CROPS WORLDWIDE DUE TO ITS GREAT NUTRITIONAL CONTRIBUTION. THIS SOCIAL AND PRODUCTIVE FIELD IS ALSO THE MAIN SUSTENANCE OF THE MANY FARMERS. THE PRESENT INVESTIGATION WAS CARRIED OUT IN THE HORCÓN SITE OF THE ROCAFUERTE CANTÓN, OF THE MANABÍ PROVINCE. THE OBJECTIVE WAS TO EVALUATE THE ABSORPTION OF NUTRIENTS (NPK) IN THE INIAP 14 VARIETY RICE CROP. A RANDOMIZED COMPLETE BLOCK DESIGN WITH FOUR TREATMENTS AND THREE REPLICATES WAS USED. THE TREATMENTS WERE ELABORATED BY APPLYING FOUR LEVELS OF NPK (0-0-0, 50-20-75, 100-40-150, 150-60-225). THE RESULTS SHOWED THAT NUTRIENT THE EXTRACTION (NPK), IN THE FIRST 25 DAYS AFTER TRANSPLANTATION, THERE WAS NOT STATISTICAL DIFFERENCE BETWEEN THE TREATMENTS, THE EFFECT WAS EVIDENT AFTER 50 DDT, WITH THE HIGHEST EXTRACTION OF NITROGEN AND POTASSIUM IN THE TREATMENT WITH THE HIGHEST APPLIED DOSE (T3), WHILE PHOSPHORUS OCCURRED IN T2.
