“EFECTO DE CUATRO NIVELES DE NPK EN LA ABSORCIÓN DE NUTRIENTES Y RENDIMIENTO DEL PASTO Brachiaria brizantha CULTIVAR MARANDÚ”

Abstract

THE BRACHIARIA BRIZANTHA GRASS AT NATIONAL LEVEL HAS TAKEN MUCH IMPORTANCE IN THE ECONOMIC PART, BECAUSE IT ADAPTS VERY WELL IN DEGRADED AREAS, BECOMING AN OPTION TO ENSURE THE FOOD SUSTAINABILITY OF LIVESTOCK. IN THE PRESENT INVESTIGATION, THE OBJECTIVE WAS TO EVALUATE THE EFFECT OF DIFFERENT LEVELS OF NITROGEN, PHOSPHORUS AND POTASSIUM ON NUTRIENT UPTAKE AND YIELD OF BRACHIARIA BRIZANTHA, THE EXPERIMENT WAS CARRIED OUT AT SAN PEDRO DE CAJONES SITE, EL CARMEN CANTON, ECUADOR, WHICH CONSISTED OF FIVE LEVELS OF NPK (0- 0 – 0, 150 – 50 – 100, 200 – 75 – 133, 250 – 100 – 174 AND 46 – 0 – 0), A COMPLETELY RANDOMIZED BLOCK DESIGN WAS USED, THE EVALUATED VARIABLES WERE: DRY WEIGHT OF LEAVES AND STEM, LENGTH OF PLANT AND EXTRACTION OF N-P-K IN STEM AND LEAVES
