There is an urgent need to match food production with increasing world population through identification of sustainable land management ***,the struggle to achieve food security should be carried out keeping in mind the soil where the crops are grown and the environment in which the living things *** agriculture(CA),practising agriculture in such a way so as to cause minimum damage to the environment,is being advocated at a large scale *** tillage,the most important aspect of CA,is thought to take care of the soil health,plant growth and the *** paper aims to review the work done on conservation tillage in different agro-ecological regions so as to understand its impact from the perspectives of the soil,the crop and the *** reports have identified several benefits of conservation tillage over conventional tillage(CT)with respect to soil physical,chemical and biological properties as well as crop *** less than 25%of the greenhouse gas effluxes to the atmosphere are attributed to *** of climate change mitigation and adaptation found zero tillage(ZT)to be the most environmental friendly among different tillage ***,conservation tillage involving ZT and minimum tillage which has potential to break the surface compact zone in soil with reduced soil disturbance offers to lead to a better soil environment and crop yield with minimal impact on the environment.&2015 International Research and Training Center on Erosion and Sedimentation and China Water and Power *** and Hosting by Elsevier *** is an open access article under the CC BY-NC-ND license(http://***/licenses/by-nc-nd/4.0/).

Sustainable vegetable production especially during the dry season requires adequate conservation of soil *** study was conducted to evaluate the sole and interactive effects of mulching(M)and poultry manure(PM)application on soil temperature(ST),crop evapotranspiration(ETc)and water use efficiency(WUE)of *** experiment was a Randomized Complete Block Design(RCBD)with three *** treatments were M at 0 and 6t ha^(-1)and PM at 0,10 and 20t ha^(-1).Soil temperature was measured using digital thermometer while ETc was determined by water depletion method using a Time Domain *** at field capacity was applied manually at 2-day *** appli-cation of mulch significantly lowered ST while joint application of 20t ha^(-1)PM(PM20)and M signifi-cantly(p≤0.05)reduced ST at 5 cm and 10 cm soil depth compared with the unmulched plots in both *** of 10t ha^(-1)PM(PM10)without M recorded the highest ETc(43.7 mm),while joint application of PM20 and M reduced ETc by about 93%compared with PM10 *** used water most efficiently when PM20 was applied under mulched *** was 62.2%increase in WUE under mulched plots compared with the control while the residual effect of PM10 and M significantly increased WUE by 65.5%.It was evident that M alongside application of PM is a good strategy for regulating ST,moderating ETc and increasing okra WUE,especially during dry season farming.

Rice–wheat cropping system(RWCS)of the South Asia is labour-,water-,capital-and energy-intensive,and become less profitable as the availability of these resources *** could be further aggravated with deterioration of soil structure,declining underground water and lesser land and water productivity which ultimately are threat in front of sustainable and profitable RWCS in the *** improving the profits,production and sustainability of this sequence-a paradigm shift is *** recommended different resource-conserving technologies(RCTs)*** tillage,laser levelling,irrigation based on soil matric potential,bed planting,direct seeding,mechanical transplanting of rice and crop diversification for this *** technologies are site specific and before selecting any particular RCT for a particular region,soil texture and agro-climatic conditions must be considered.A solitary approach/RCT might not be effective to solve the upcoming issue of producing more food grains with inadequate available water and ***,an integrated approach is *** before implementing any approach,different issues relating to RWCS must be discovered,considered and addressed in a holistic *** this review,an attempt was made to highlight different issues resulted from the practise of intensive rice–wheat cropping sequence of the region,which must be considered while framing and implementing any integrated approach/project such as conservation agriculture for improving the productions,profits and sustainability of RWCS in the region.
