Resource conservation technology for sustainable production of wheat: A review
K Mondal, GC Malik, M Banerjee, K Jana
Wheat is a major food security crop in South Asia, with 42% of the wheat in this region grown following rice on 13.5 million hectares of land. Resource-conserving technologies, described in this chapter, offer considerable potential for improving the sustainability and productivity of wheat in the rice-wheat cropping system of South Asia. These include raising input use efficiency, cutting costs, providing various environmental benefits, and ultimately improving farmer livelihoods and helping to reduce poverty. The conservation technologies described here are in the form of reduced tillage, zero-tillage, and bed planting for wheat in the rice-wheat system. These technologies effectively attempt to solve the problems of late wheat planting and poor plant stands, which limit yields under rice-wheat rotations. Conservation agriculture systems appear to be appealing options to achieve sustainable and intensive crop production under different agro-ecological environments because they use available resources efficiently and maintain soil fertility. However, there is a need for wider scale testing of these new technologies under diverse production systems, as the CA technologies are site specific and therefore appraisal of CA is important to have significant adoption.
