| Abstract | A field experiment was conducted at ICAR-IISR, Lucknow, in a split-plot design with two cropping systems and eight different crop residue management practices. In main plots, cropping systems, viz. CS$_{1}$—rice–wheat (R–W) and CS$_{2}$—sugarcane (plant crop)–ratoon–wheat (S–R–W) and subplots residue management practices, viz. residue removal (T$_{1}$-RR); residue burning (T$_{2}$-RB); residue incorporation (T$_{3}$-RI); residue incorporation + Trichoderma (T$_{4}$-RI + T), residue incorporation +25 % extra nitrogen application (T$_{5}$-RI + N), partial residue incorporation (T$_{6}$-PRI), partial residue incorporation + Trichoderma (T$_{7}$-PRI + T) and partial residue incorporation +25 % extra nitrogen application (T$_{8}$-PRI + N), were allocated. The observations on soil physical parameters indicated the lower mean bulk density (1.10 Mg m$^{−3}$) in sugarcane–ratoon–wheat system than the rice–wheat system (1.145 Mg m$^{−3}$). Increased porosity (58.68 %) was obtained in sugarcane–ratoon–wheat (S–R–W) system as compared to rice–wheat system (56.83 %). In S–R–W system, higher (19.51 %) SOC was recorded than the R–W system (16.31 Mg ha$^{−1}$) at 0–15 cm depth. After harvesting of wheat in both the cropping systems, higher total carbon sequestered (@1.42 Mg ha$^{−1}$) in S–R–W system than the R–W cropping system (0–15 cm soil depth). Higher contents of available nitrogen, phosphorous and potassium were recorded in S–R–W system than the R–W system after completion of crop cycle. The agronomic efficiency of rice, wheat and sugarcane crops indicated the higher level with residue incorporation along with Trichoderma application. Thus, it could be concluded that sugarcane–ratoon–wheat system acted as soil fertility restorer and crop reside management along with application of Trichoderma sustained the soil carbon level, crop productivity and agronomic/production efficiency of N for longer period. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
