Influence of Different Proportion Intercropping on Oat and Common Vetch Yields and Nutritional Composition at Different Growth Stages

Crop yield mainly depends on environment and cultivation practices that vary according to a growing environment. However, an oat (Avena sativa L.)-common vetch (Vicia L.) intercrop system has not been fully developed in the agro-pastoral ecotone of Inner Mongolia, China. This study evaluated effects seven treatments, including five oat-common intercropping patterns, sole oat, quality performance at different growth periods [75 days after sowing (DAS), 90 DAS, 105 DAS], basis field experiments conducted Mongolia 2015 2016. The OV3:1 (oat intercropped with common seeding ratios 3:1) treatment DAS 2016 was superior other as it achieved highest shoot dry matter, increasing by 24.1% 37.1% compared vetch. crude fat (CF) contents, CF yield, protein (CP) increased under OV3:1, acid detergent fiber (ADF) decreased monoculture. results indicate is efficient cropping for Mongolia. appropriate proportion 3:1 harvesting time only increases crop but also improves quality.
