Productivity of winter rye in organic vs. Conventional cropping system

Abstract

Rye is a cereal which is very much demanded at the market, for making a special kind of bread, but it is little grown in Serbia. The aim of this paper is to investigate possibilities of organic growing of winter rye, comparing with the conventional one, in agroecological conditions of Valjevo hilly region during 2008/2009 and 2009/2010 cropping seasons. The trial was set up in a village of Kotešica, on soil which had not been used for agriculture for 7 years. In organic cropping system three combinations of microbiological fertiliser baktofil with zeolite and hydrogel were used prior to sowing. Half of each plot was treated with foliar microbiological fertiliser Slavol during crop growing period. In conventional cropping system three variants with mineral fertilisers were included: NPK, NPK+zeolite, NPK+hydrogel. Results of the yield obtained in the experiment showed a significant difference between two seasons, 2008/2009 and 2009/2010. In comparison with the control, the treatments in an organic cropping system resulted with statistically insignificant differences for mean values in both years, while the mean in conventional cropping system has significantly higher yield of winter rye. Organic cropping system under conditions of Valjevo hilly region did not give significantly lower rye yield compared with the conventional one in a moderate growing season such was 2008/2009. The combination of soil microbiological fertiliser (Baktofil) with foliar fertiliser (Slavol) and zeolite gave the highest winter rye grain yield in all other treatments in the second year of investigation. In a very wet season (2009/2010) mineral fertiliser NPK showed an advantage, especially in combinations with zeolite, and this treatment can be recommended

“Organic is More of an American Term … We Are Traditional Farmers”: Discourses of Place-based Organic Farming, Community, Heritage, and Sustainability

“…In addition to using organic fertilizers and pesticides (if pesticides are used at all), organic farms are often substantially smaller, use multiple crop rotation (rotating more than two different crops) and intercropping (growing multiple kinds of crops right next to one another, often in alternating rows), employ alternative seeding methods, conserve water, and input less energy. Oljača, Dolijanović, Glamočlija, Đorđević, and, Oljača (2010) studied the uses of organic and inorganic fertilizers and found little differences in the yields and nitrate leaching in the first two to three seasons on both organic and conventional farms. However, multiple seasons later, the organic nitrate runoff was much lower than that for inorganic fertilizers, and organic yields improved substantially over time, which was thought to be a result of nitrogen and other nutrient build-up common with organic fertilizers.…”
