Abstract
En todo el mundo, la principal fuente alimenticia para los herbívoros es el forraje como la espina de mar, en ese sentido, la investigación tuvo el objetivo de evaluar el comportamiento agronómico de la espina de mar con la aplicación de tres láminas de riego por goteo e incorporación de hidrogel en predios de la Estación Experimental Choquenaira. Los tratamientos fueron 20%, 40% y 60% de láminas de riego y 5 g de hidrogel por planta, que fueron dispuestos bajo un diseño de bloques completos al azar con cuatro repeticiones, las variables de estudio fueron el porcentaje de prendimiento, altura de planta, número de ramas primarias, número de ramas secundarias, diámetro del tallo y número de hojas, la evaluación fue a los 30 días después de la primera aplicación de riego a seis plantas que fueron identificadas del muestreo al azar por cada tratamiento, así también se determinó el rendimiento de materia seca. Los resultados muestran mayor porcentaje de prendimiento, mayor altura de planta, mayor número de ramas secundarias, mayor número de hojas y mayor rendimiento en materia seca en comparación con otras investigaciones realizadas en la región. El tratamiento 3 fue mejor respecto a los demás tratamientos con la aplicación de 60% de lámina re riego durante el desarrollo del cultivo, por otro lado el tratamiento 2, que tiene 40% de lámina de riego presentó mayor número de ramas primarias frente a los demás tratamientos, en tal sentido se concluye que a mayor número de ramas secundarias mayor número de hojas y mayor producción de forraje para el consumo del ganado. Asimismo, con la aplicación del 60% de lámina de riego produce mayor rendimiento por hectárea, obteniendo 2455.34 kg ha-¹.
Throughout the world, the main food source for herbivores is forage such as the sea spine, in this sense; the research had the objective of evaluating the agronomic behavior of the sea spine with the application of three sheets of drip irrigation and hydrogel incorporation at Choquenaira Experimental Station. The treatments were 20%, 40% and 60% of irrigation sheets and 5 g of hydrogel per plant, which were arranged under a randomized complete block design with four repetitions, the variables of the study were the percentage of capture, height of plant, number of primary branches, number ofsecondary branches, diameterofthestem and number of leaves, the evaluation was at 30days after the first application of irrigation to six plants that were identified from random sampling for each treatment, as well the yield of dry matter was determined. The results show a higher percentage of yield, higher plant height, greater number of secondary branches, greater number of leaves and higher yield in dry matter compared to other investigations carried out in the region. Treatment 3 was better compared to the other treatments with the application of 60% re-irrigated foil during the development of the crop, on the other hand treatment 2, which has 40% of irrigation foil presented a greater number of primary branches compared to other treatments, in this sense it is concluded that the greater the number of secondary branches, the greater the number of leaves and the greater the production of forage for livestock consumption. Also, with the application of 60% of irrigation sheet produces higher yield per hectare, obtaining 2455.34 kg ha-¹.
