Conservation of agriculture in the western Indo-gangetic plains' irrigated cotton–wheat and guar-wheat system

Conserving natural capital and optimizing factor productivity in semi-arid regions has been a great challenge in achieving sustainability of the production system. Cotton-wheat and guar-wheat based cropping system plays a predominant role under evolving climatic scenarios by sustainable conservation of natural resources. In the present study, the effect of long-term zero-tillage practices on selected physico-chemical and microbiological properties was determined in different cropping system at 0-15 and 15-30 cm soil depth in Mahendergarh (Tigra) district of Haryana (latitude- 28.030N and longitude- 76.100E) during the year 2006.
