EFECTO DE LA DENSIDAD POBLACIONAL EN EL COMPORTAMIENTO AGRONÓMICO Y PRODUCTIVO DE LA VARIEDAD DE ALGODÓN “BRS-336”

Abstract

IN THE PRESENT INVESTIGATION, THE EFFECT OF THE SPACING BETWEEN LINES AND BETWEEN PLANTS ON THE GROWTH, DEVELOPMENT AND PRODUCTION OF THE COTTON VARIETY BRS-336 WAS EVALUATED. THIRTEEN PLANTING DENSITIES 55556, 37037, 27778, 50000, 33333, 25000, 45455, 30303, 22727, 41667, 27778, 20833 AND 62500 PL HA-1 WERE USED, WITH SINGLE ROW PLANTING ARRANGEMENTS, RESULTING IN THIRTEEN TREATMENTS, REPLICATED FOUR TIMES. THE VARIABLES RECORDED WERE GERMINATION PERCENTAGE, PLANT HEIGHT (CM), DAILY PLANT HEIGHT INCREASE (CM), PLANT HEIGHT INCREASE (CM) BETWEEN DEVELOPMENT PHASES, STEM DIAMETER (MM), NUMBER OF INTERNODES OF THE STEM, INTERNODE LENGTH (CM), TOTAL NUMBER OF BRANCHES / PLANT, NUMBER OF BRANCHES / PLANT ABOVE THE FIRST FLOWER, NUMBER OF PRODUCTIVE BRANCHES / PLANT, DAYS AT CLOSE OF CROP, CHLOROPHYLL INDEX (PHOTOSYNTHETIC PIGMENTS), DAYS TO APPEARANCE OF THE FIRST FLOWER BUD AND NUMBER OF FLOWER BUDS / PLANT, DAYS TO THE OPENING OF THE FIRST FLOWER AND NUMBER OF FLOWERS / PLANT, DAYS TO THE APPEARANCE OF THE FIRST ACORN AND AVERAGE NUMBER OF ACORNS / PLANT, DAYS TO THE OPENING OF THE FIRST COCOON AND NUMBER OF COCOONS / PLANT, YIELD IN KG / PLOT AND KG HA-1, FIBER-SEED RATIO, INCIDENCE OF CUTWORMS, INCIDENCE OF OTHER ARTHROPODS AND PERCENTAGE OF DISEASED ACORNS
