Investigating the Effects of Different Levels of Vermicompost and Irrigation on the Yield and Quality of Quinoa (Chenopodium quinoa Willd.) Forage

In order to investigate the effect of different levels of vermicomposting and irrigation on the yield and quality of quinoa forage, this experiment was conducted as a split plot based on a randomized complete block design in the research farm of Kurdistan University located in Dehgolan in 1400. The experimental factors included 4 levels of irrigation equal to 50, 75, 100, and 125% of the water requirement of the quinoa plant and the sub-factor included 4 levels of vermicompost fertilizer equal to 0, 5, 10 and 15 tons per hectare respectively. The highest plant height (111.47 cm), grain yield (2374.51 kg/ha), biological yield (5415.84 kg/ha), and digestible dry matter (59.49 %) in the treatment of 125% of plant water requirement and 15 tons per hectare of vermicompost was observed. The highest amount of crude protein of forage (15.71%) forage ash (18.91%) and water use efficiency (0.53 kg/m3) was in the treatment of 15 tons of vermicompost per hectare. Therefore, by improving the environmental conditions through the application of vermicompost and the water consumption required by the quinoa plant, its yield and quality can be increased.
