Abstract

Field experiments were conducted in Madhya Pradesh, India, on chickpea after soyabean under varied nutrient management situations and tillage systems, during 2001-02 to 2004-05, in Vertisols, to assess the stability and sustainability of chickpea production. Pooled results revealed that the chickpea yield remained unaffected due to tillage systems, which indicated that the degree of tillage could be reduced without compromising the yield of chickpea, and was further authenticated by more or less identical values of sustainability yield index and stability. The application of nutrients either in kharif (organic manure) or in rabi seasons (chemical fertilizer) increased the yield of chickpea by 19.2% (9-26%) over the control. The residual effect of these organic sources enhanced the chickpea yield by 11.2% over the control. This residual effect was further pronounced when coupled with 50% RDF (around 20.65%) or 100% RDF (25.2%). Sustainability yield index showed that the application of nutrients through either of the sources or their integration is capable of producing minimum guaranteed yield in the range of 24-26% of the potential chickpea yield. The residual effect of farmyard manure, either alone or with integration, ensured better performance of chickpea under unfavourable conditions and was also found stable. The relative stability showed that most of the fertilizer treatments behaved identically.
