Evaluación de sistemas de siembra de alta densidad en maíz (zea mays l.)

Abstract

The work was carried out at the "Santa Inés" Experimental Farm, which belongs to the Technical University of Machala, located in the province of El Oro, Machala. The objective of the work was to evaluate different systems of high planting densities in corn. A randomized block factorial design was used with 5 treatments with two replications each. The variables studied were: row arrangement, ear damage, ear weight, ear length, ear diameter, ear diameter, ear weight, ear diameter, rachis diameter, grain moisture, volume of 100 seeds, weight of grains per ear and yield. The best treatment was T4 in the yield variables where ear weight, ear diameter, 100-grain weight, with a higher production (23,044.76 kg/ ha-1), without showing statistical significance in terms of yield. T5 had the lowest damage index in the ear. The study showed that high-density planting has a direct positive impact on corn crop production, complemented with good management from soil preparation to post-harvest, high yields can be obtained, increasing profitability for the producer.
