Synopsis (short abstract) This technical paper was prepared by a senior FAO agronomist in the Investment Centre Division and draws on the results of two missions carried out in June 2008 and April 2009 by teams of Centre, World Bank and national staff to assist implementation of the World Bank-financed Agricultural Competitiveness Project. The study reviews the potential for zero-tillage (no-till or direct seeding) to increase wheat yields in Northern Kazakhstan by 20 to 50 percent above current levels. The possible aver age production increase from this achievement could be about 1 million additional tonnes of wheat annually. Eventual wide adoption of zero-tillage technology could also bring about a global benefit by contributing to improved carbon storage, which would also have a positive effect on climate change due to decreased greenhouse gas emissions. The paper notes that continued support and increased emphasis on conservation agriculture could significantly contribute to improving food security and the o verall cereal and grain production system competitiveness in Kazakhstan. However zero-tillage does not mean no-farming input. In fact it requires investment to adapt or buy new machinery and use of herbicides, during the first years of technology establishment. Yet the payoff can be well worth it with a potential rate of return on the investment as high as 18-23 percent. The zero-tillage results described in this paper could apply to similar climates and farming systems in other countries.

    Zero / minimum tillage in rice-wheat system in Nepal 2013

    By tradition, in the Terai region farmers believe that wheat planting needs well-prepared and pulverized soil for high yields, carrying out several plowings and harrowing. However, after rice, land is marshy or wet and ploughing is not possible, delaying wheat planting. Zero or minimum tillage provides minimum disturbance of the soil by placing the seeds directly in furrows. Seeds are then covered with well-decomposed compost and rice stubbles left in the field. Some advantages of zero-tillage is the reduction of about 30% in the use of water, compared to conventional tillage, as well as an improvement in the physical properties of soil. In addition, by planting wheat in time, higher yields may be obtained.

    Zero tillage development in tropical Brazil
    The story of a successful NGO activity

    The adoption of Conservation Agriculture (CA) goes counter to the notion in force for thousands of years that soil must be cultivated before sowing or planting. Teaching the concept of CA, and examining methods and experiences of introducing it into farming practice, are essential for achieving the necessary changes in attitude and behaviour among present and future agricultural researchers, technicians and practiotioners. The experience described in this case study is rich in insights as to how the phenomenal growth of CA in Brazil, and especially in the tropical areas, has been promoted. The study describes, with much perception, the activities of a small number of people working both individually and in NGOs who are promoting a completely new system - which has already proved successful in the more temperate parts of Brazil - for other more tropical and poorer parts of the country. This publication was developed as course material for students in agriculture or related subjects deal ing with decision-making processes in agriculture; it is; however, of interest to all those involved in the promotion of conservation agriculture.
