Determinación de tres densidades de siembra para cuatro materiales de cebada maltera (Hordeum vulgare L.) con siembra mecanizada en la Estación Experimental Tunshi

Abstract

The aim was to determine the three sowing densities for four malting barley (Hordeum vulgare L.) materials with mechanized sowing at Tunshi Experimental Station. The methodology used was a randomized complete block design with three replications and a total of 36 experimental units, where the varieties ABI Voyager, 2IK16-0671, 2IK16-0710 and 2IK16-0812 were analyzed with mechanized sowing densities of 75, 100 and 125 kg/ha, yield data per treatment were recorded, as well as agronomic behavior and benefit/cost ratio, the data were analyzed by statistical tests to determine the significant differences relevant to the study. It was determined that variety 2IK16-0812 at 100 kg/ha had a higher yield with 4.68 t/ha, variety 2IK16-0671 with densities of 125, 100 and 75 kg/ha presented the lowest number of days to physiological maturity with 115, 115 and 114 days and variety 2IK16-0812 at 100 kg/ha presented a higher B/C ratio with a value of 1.92. It was concluded that these differences may be due to collective factors, both physical and biotic factors, so it is recommended to carry out further research with more detailed analysis in relation to these factors, as well as the introduction of new products to the crop and much broader economic studies that benefit national agro-producers.
