“EFECTO DE LA FERTILIZACIÓN NITROGENADA ORGÁNICA E INORGÁNICA ACOMPAÑADA DE MICROORGANISMOS EFICIENTES SOBRE EL COMPORTAMIENTO PRODUCTIVO DEL ALGODÓN (Gossypium Hirsutum, L.)”.

Abstract

THE COTTON CROP (GOSSYPIUM HIRSUTUM L.) IS ONE OF THE MOST IMPORTANT DOMESTICATED PLANTS FOR HUMANITY WITH MORE THAN 400 INDUSTRIAL APPLICATIONS. THE USE OF ORGANIC FERTILIZERS IS AN ALTERNATIVE FOR AGRICULTURE OF GREAT IMPORTANCE FOR THE MAINTENANCE OF SOIL MICROORGANISMS, IMPROVING THE STRUCTURE, AERATION, MOVEMENT AND RETENTION OF SOIL MOISTURE AND REDUCING COMPACTION. THUS, THE PRESENT RESEARCH AIMS TO EVALUATE THE EFFECT OF ORGANIC AND INORGANIC FERTILIZATION ACCOMPANIED WITH EFFICIENT MICROORGANISMS ON THE PRODUCTIVE BEHAVIOR OF COTTON, IN DIFFERENT DOSES OF NITROGEN. SIXTEEN TREATMENTS WERE EVALUATED USING THE EXPERIMENTAL DESIGN IN COMPLETELY RANDOMIZED BLOCKS IN A 2X4X2 FACTORIAL ARRANGEMENT, CORRESPONDING TO TWO TYPES OF NITROGEN SOURCES (ORGANIC MATTER AND UREA) BY FOUR DOSES OF NITROGEN FROM THEIR SOURCES (50, 100, 150, 200 KG OF N HAˉ¹) AND BY APPLICATION OF EFFICIENT MICROORGANISMS (ME) (WITH AND WITHOUT APPLICATION). THE FOLLOWING VARIABLES WERE STUDIED: DAYS TO FLOWERING, PLANT HEIGHT, STEM DIAMETER, NUMBER OF BOLLS PER PLANT, DIAMETER OF BOLLS, LENGTH OF BOLLS, NUMBER OF SEEDS PER BOLLS, WEIGHT OF CAPSULES, WEIGHT OF FIBER, WEIGHT OF SEEDS AND PERFORMANCE. UREA CAUSED GREATER EFFECTS ON THE PRODUCTIVE VARIABLES STUDIED.
