Efecto del espaciamiento entre hileras usando siembra directa y trasplante sobre el rendimiento de Chenopodium quinoa var. tunkahuan, bajo las condiciones de la hoya de Loja

Quinoa is a crop of great importance due to its worldwide expansion in recent years, thanks to its high nutritional value and adaptability. In Ecuador, it is cultivated in the Sierra region with yields ranging from 1.5 to 3 t/ha. However, the yield of this crop can be affected by various abiotic and biotic factors. The spatial arrangement of plants in the field is one alternative that can significantly increase production, provided that the plantation is managed properly. The objective of the present study was to evaluate the effect of row spacing using direct sowing and transplanting on the yield of Chenopodium quinoa var. tunkahuan under the conditions of the Loja valley. The trial was conducted at the Experimental Teaching Farm 'La Argelia,' located in Loja city. The experimental design was completely randomized with a bifactorial arrangement consisting of 8 treatments and 3 replications, including two sowing methods (direct sowing and transplanting) and four spatial arrangements (single row 25 cm, single row 50 cm, double row 50-25-25, triple row 50-25-25-25). During the crop cycle, the following variables were recorded: phenology, biomass, plant height, vegetation cover, chlorophyll content, and leaf area. The variables of grain number, thousand-grain weight, yield, and harvest index were recorded when the crops reached physiological maturity. When analyzing the morphological variables, it was observed that the highest average biomass, leaf area, and vegetation cover were obtained through direct sowing with a spatial arrangement of 25 cm. Plant height and chlorophyll content were greater in direct sowing with a spatial arrangement of 50 cm. Quinoa yield exceeded the national average, with productions of 4.34 t ha-1 in direct sowing and 4.02 t ha-1 in a single-row spatial arrangement of 50 cm. It can be concluded that the management practices applied throughout the crop cycle directly influence its production. Keywords: Quinoa, yield components, planting distance, continuous jet.
