“EFECTO DE LA FERTILIZACIÓN NITROGENADA ORGÁNICA E INORGÁNICA Y DE LA APLICACIÓN DE MICROORGANISMOS EFICIENTES SOBRE EL CRECIMIENTO VEGETATIVO DEL ALGODÓN (Gossypium hirsutum L.)”

Abstract

COTTON HAS BEEN USED FOR MANY YEARS IN DIFFERENT REGIONS OF THE WORLD AND AT THE SAME TIME ITS USE GENERATES HIGH EMPLOYMENT OPPORTUNITIES. THE CURRENT COTTON PRODUCTION SYSTEM IS CHARACTERIZED BY USING A LARGE AMOUNT OF INPUTS, WATER, FERTILIZERS AND INSECTICIDES, IN VIEW OF THIS, ORGANIC AGRICULTURE IS PRESENTED AS AN ALTERNATIVE WITH AN ECOLOGICAL BASE THAT AVOIDS THE USE OF SYNTHETIC PRODUCTS SUCH AS CHEMICAL FERTILIZERS, PESTICIDES, HERBICIDES AND OTHERS THAT CAN CAUSE FOOD OR ECOSYSTEM CONTAMINATION. THE OBJECTIVE OF THIS WORK WAS TO DETERMINE THE EFFECT OF FERTILIZATION WITH ORGANIC AND INORGANIC NITROGENOUS SOURCES WITH AND WITHOUT EFFICIENT MICROORGANISMS (EM), ON GROWTH VARIABLES. FOR THIS, AN OPEN FIELD TRIAL WAS CARRIED OUT AND 70 DAYS AFTER SOWING THE FOLLOWING VARIABLES WERE DETERMINED ROOT VOLUME (RV), PLANT HEIGHT (PH), STEM DIAMETER (SD), LEAVES NUMBER (LN), LEAF AREA (LA), CHLOROPHYLL INDEX (CI), ROOT DRY WEIGHT (RDW), STEM DRY WEIGHT (SDW) AND LEAF DRY WEIGHT (PSH).
