A study on evaluation of conservation agriculture and nitrogen management practices in wheat (Triticum aestivum L.) under maize ((Zea mays L.)-wheat cropping system was undertaken at the ICAR-Indian Agricultural Research Institute, New Delhi. Experiments were conducted in split-plot design with six main-plot treatments of tillage and crop establishment techniques, viz. conventional tillage-flat (CT-F), zero tillage-flat (ZT-F), CT-bed (CT-B), ZT-B, ZT-F with residue (ZT-F+R) and ZT-B with residue (ZT-B+R), while sub-plot treatments consisted of four nitrogen (N) levels, viz. 0, 60, 120 and 180 kg/ha. The results revealed that the minimum energy requirement for the production of wheat crop was estimated with ZT-B system which saved on an average 19.1 % input energy over the CT practices. | Resource-use efficiency of wheat Effect of conservation agriculture and nitrogen management practices in maize Zea mays wheat Triticum aestivum cropping system
