To date, global agricultural development has focused on increasing productivity rather than holistic natural resource management for food security. Therefore, the development of more sustainable agricultural practices on a large scale is of utmost importance. However, information on the performance of cropping systems under organic and conventional management in tropical and subtropical regions is scarce. <\/p>\n\n\n\n<p><a href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0081039\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"This study (\u00f6ffnet in neuem Tab)\">This study<\/a> presents agronomic and economic data from the conversion phase (2007-2010) of a comparative trial of cropping systems on a Vertisol soil in Madhya Pradesh, central India. A cotton-soybean-wheat crop rotation under biodynamic, organic, and conventional (with and without Bt cotton) management was studied. A significant yield gap was observed between organic and conventional cropping systems in the first cropping cycle (Cycle 1: 2007-2008) for cotton (-29%) and wheat (-27%), whereas in the second cropping cycle (Cycle 2: 2009-2010), cotton and wheat yields were similar in all cropping systems due to lower yields in conventional systems. In contrast, organic soybean (a nitrogen-fixing legume crop) yields were slightly lower than conventional yields (-1% in cycle 1, -11% in cycle 2). Averaged across all crops, conventional cropping systems achieved significantly higher gross margins in cycle 1 (+29%), while in cycle 2 gross margins were significantly higher in organic cropping systems (+25%) due to lower variable production costs at similar yields. Soybean gross margins were significantly higher (+11%) in organic than conventional systems across the four crop years. <\/p>\n\n\n\n<p>Our results suggest that organic soybean production is a viable option for smallholder farmers under the prevailing semi-arid conditions in India. Future research needs to clarify the long-term productivity and profitability, particularly of cotton and wheat, as well as the ecological impacts of different cropping systems.<\/p>\n\n\n\n<div class=\"wp-block-button is-style-squared new-tab\"><a class=\"wp-block-button__link has-text-color has-black-color has-background has-grey-background-color\" href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0081039\">zur Studie<\/a><\/div>\n\n\n\n<p>To the 2021 study: <a href=\"https:\/\/biore-stiftung.ch\/en\/news\/a-synthesis-of-twelve-years-of-syscom\/\">A synthesis of twelve years of SysCom<\/a><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/biore-stiftung.ch\/wp-content\/uploads\/2020\/02\/Coop_1S2W8967-1024x683.jpg\" alt=\"\" class=\"wp-image-281\" srcset=\"https:\/\/biore-stiftung.ch\/wp-content\/uploads\/2020\/02\/Coop_1S2W8967-1024x683.jpg 1024w, https:\/\/biore-stiftung.ch\/wp-content\/uploads\/2020\/02\/Coop_1S2W8967-300x200.jpg 300w, https:\/\/biore-stiftung.ch\/wp-content\/uploads\/2020\/02\/Coop_1S2W8967-768x512.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\t<\/div>\n\t\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yield and economic performance of organic and conventional cotton-based cropping systems &#8211; results of a field trial in India<\/p>\n","protected":false},"featured_media":282,"template":"","kategorie":[23],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.8 -
