Evaluación del efecto de tres sistemas de siembra en el rendimiento de dos variedades de amaranto (Amaranthus quitensis) y (Amaranthus hypochondriacus)

Abstract

In Ecuador the cultivation of amaranth has become an important economic line because of its nutritional quality. With respect to cultivation, there is little knowledge about the varieties and the different systems of sowing and the yields that can be reached. The objective of this work was to evaluate three systems of sowing (S1), by blow (S2) and by transplant (S3) in two amaranth varieties Amaranthus quitensis (V1) and Amaranthus hypochondriacus (V2). The research was carried out at the Querochaca Experimental Teaching Farm of the Technical University of Ambato, located in Cevallos, Tungurahua province, at an altitude of 2 865 msnm. Six treatments with four replications were studied, with an experimental design of split plots. Variance analyzes were performed; Tukey tests at 5%; And tests of Significant Minimum Difference at 5% for factor varieties. The best result was obtained with T1 (S1V1) with a yield of 1.17 kg / plot that projected to hectares was 2321.42 kg / ha. While T6 (S3V2) presented the lowest yield 0.87 kg / plot. From the point of view of cost benefit the T1 was also the best (0.60 USD). It is therefore recommended that farmers use this continuous stream planting system and use Amaranthus quitensis.
