Organic farming in Soybean-wheat cropping sequence

During 2005-06 to 2007-08, a field experiment on organic farming in soybean-wheat cropping sequence was conducted to evaluate organic vis-à-vis inorganic fertilizers for the cropping system and also for soil sustainability. Grain yield of both the crops, i.e. soybean (31.67 qha⁻¹) and wheat (52.92 qha⁻¹), was observed to be significantly superior by fertilizer application as per general recommended dose of respective crops. Integrated application of fertilizers i.e. inorganic fertilizers 50% and organic fertilizers 50% was found to be the next superior treatment to that of general recommended dose. Soil properties were improved by use of organic and inorganic fertilizers in combination. However, no significant change was observed in case of soil pH and electrical conductivity.
