Spring-Planted Cover Crop Impact on Weed Suppression, Productivity, and Feed Quality of Forage Crops in Northern Kazakhstan

Integrating cover crops into crop rotation could provide options for herbicide-resistant weed control in farming systems. To evaluate the potential effectiveness of spring-planted oats (Avena sativa L.) on suppression, productivity, and feed quality annual forage as sole intercrops order to determine best agroecological technique, two-year experiments were laid out under arid conditions Akmolinsk region northern Kazakhstan. Three crops, namely, (Piper) Stapf.-Sudan grass (Sorghum sudanense) (control), common millet (Panicum miliaceum L.), Japanese (Echinochloa frumentacea three intercropping systems, i.e., 50% pea (Pisum sativum + barley (Hordeum vulgare L.); 40% 30% Sudanense) Stapf.-sudan Sudanense), well six mentioned treatments with plus used. is a promising newly introduced It was revealed that significantly reduced density their intercrops. In all cases, integrating showed higher productivity than non-covered treatments. A highly productive grown without intercrop Sudan grass. The highest yield among systems recorded constituting barley. crude protein content biomass from crops. overall view use including methods be integrated chemical non-chemical field valuable way reduce pressure improve during vegetation period.
