    Agriculture remains central to the Indian economy, providing livelihood to the majority of its population. Though Indian agriculture have made spectacular progress for food self-sufficiency, yet growing challenges of large management yield gaps, low water and nutrient efficiency, imbalance and inadequate use of external production inputs, diminishing farm profits, deterioration of soil health and environmental quality coupled with climate risks are major concerns. Feeding a growing population with increasing dietary preferences for resource-intensive food products is a major challenge. Moreover, with no scope for horizontal expansion of farming to produce needed food; improving agronomic productivity and achieving high and stable yields under changing and uncertain climate are important for feeding the growing population. Increasing climatic variability affects most of the biological, physical and chemical processes that drive productivity of agricultural systems. The productivity and stability of agricultural systems depends upon measurable factors and processes controlled by climate and non-climate drivers of production paradigm. It is therefore vitally important to develop strategies and practices to sustainably increase food production while increasing farm income, protecting natural resources and minimizing environmental footprints.

    Tillage and rice straw management affect soil enzyme activities and chemical properties after three years of conservation agriculture based rice-wheat system in north-western India
    (SCIENCEDOMAIN international, 2017) Kharia, S.; Thind, H.S.; Sharma, S.; Sidhu, H.S.; Jat, M.L.; Yadvinder-Singh
    Aims: To evaluate the effects of rice establishment, tillage and rice straw management on changes in soil enzyme activities and chemical properties in soil after three cycles of continuous rice-wheat system. Study Design: The experiment was laid in split plot design with three replications. Place and Duration of Study: PAU, Ludhiana, 2010-2013. Methodology: The experiment was started during kharif season of 2010. The design of an experiment was having 12 treatments with 3 replications. The main plot treatments in rice (zero till direct seeded rice, ZT-DSR; conventional till direct seeded rice, CT-DSR; zero till direct transplanted rice, ZT-DTR and puddled transplanted rice, PTR) and three sub-plot treatments in wheat (conventional till wheat without rice straw, CTW-R; ZT wheat without rice straw, ZTW-R, and ZT wheat with rice straw retained as surface mulch using Happy Seeder, ZTW+R). Results: Zero tillage with rice straw retention (ZTW) as surface mulch (+R) increased wheat yield by 9% and 15% compared with conventional tillage (CTW) and ZTW with no residue (-R). Significantly higher dehydrogenase, fluorescein diacetate, alkaline phosphatase, phytase and urease activities were recorded under ZTW+R compared with ZTW/CTW-R in 0-5 cm soil layer. Organic carbon, Olsen-P, available K and DTPA-extractable micronutrients (Zn, Fe, Mn and Cu) in the surface 0-5 cm soil layer were significantly higher in ZTW+R compared with ZTW/CTW-R. Soil enzyme activities were significantly and positively correlated with each other, soil organic carbon, Olsen-P and grain yield of wheat. Conclusion: We concluded that RCTs (ZTW and rice residue retention) improve soil enzyme activities and chemical properties in surface 0-5 cm soil layer and enhance productivity and sustainability of rice-wheat system.
