Description |
A field experiment was conducted during 2003-06 on deep Vertisols of Bhopal to study the effect of 3 organic manures, viz poultry manure, vermicompost and cattledung manure vis-a vis chemical fertilizers on the productivity, soil fertility and economics of soybean (Glycine max L. Merr.) - durum wheat (Triricum durum Desf.) cropping system. In the first year (2003-04), chemical fertilizers recorded significantly higher yield of crops and application of organic manures recorded 7.3 to 13.3 % reduction in soybean yield and 7.8 to 14.8 % reduction in wheat yield. In the second year (2004-05), soybean yield was on par among the nutrient sources and wheat yield was on par between chemical fertilizers and poultry manure treatment. In the third year (2005-06), application of organic manures recorded similar yields to that of chemical fertilizers and in fact, poultry manure application resulted in 17.5 and 3.2 % higher yields of soybean and wheat, respectively, over the chemical fertilizers. The protein and oil content of soybean was not affected among the treatments but the protein content of wheat was lower in control compared to the application of either chemical or organic manures. At the end of the 3 cropping cycles, soil organic carbon, available N, P, K status and enzyme activity of soil (dehydrogenase and phosphatase activity) were significantly improved in organic manure treatments compared to chemical fertilizers. The economics of soybean - durum wheat cropping system was in favour of chemical fertilizers during the first 2 years but in the third year, organic farming resulted in better economic returns due to improved productivity and lower cost of cultivation compared to chemical farming.
