Ano: 2010 URL: http://purl.umn.edu/118419 Impact of Zero Tillage in India's Rice-Wheat Systems AgEcon Laxmi, Vijay; Erenstein, Olaf; Gupta, Raj K.. To date, the most widely adopted resource conserving technology (RCT) in the Indo-Gangetic Plains (IGP)has been zero-tillage (ZT) for wheat after rice, particularly in India. This report reviews and synthesizes the experience with zero tillage in the Indian IGP. Zero tillage of wheat after rice generates significant benefits at the farm level, both in terms of significant yield gains (6–10%, particularly due to timelier planting of wheat) and cost savings (5–10%, particularly tillage savings). These benefits explain the widespread interest of farmers and the rapidity of the diffusion across the Indian IGP, further aided by the wide applicability of this mechanical innovation. The study subsequently reports on the findings of village-level focus-group...

Ano: 2007 URL: http://purl.umn.edu/56093 Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Punjab, Pakistan AgEcon Farooq, Umar; Sharif, Muhammad; Erenstein, Olaf. This study documents the adoption and impacts of zero-tillage (ZT) wheat in the ricewheat systems of Pakistan’s Punjab province primarily drawing on a detailed empirical survey of 458 rice-wheat farmers. Our random stratified sample revealed 19% to be ZT wheat adopters and a similar share of the wheat area in the surveyed communities to be under ZT. The study suggests that diffusion has stagnated and also flags the issue of disadoption (14%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 7 tractor hours and 35...

Ano: 2007 URL: http://purl.umn.edu/56095 Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia AgEcon Erenstein, Olaf; Farooq, Umar; Malik, R.K.; Sharif, Muhammad. The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

Ano: 2007 URL: http://purl.umn.edu/91816 Controlling Phalaris Minor in the Indian Rice-Wheat Belt AgEcon Vincent, David P.; Quirke, Derek. The ACIAR-managed project CS1/1996/013, Herbicide-resistant weeds of wheat in India and Australia: integrated management, was designed to find a long-term method of control of Phalaris minor, a problem weed of the rice–wheat cropping system of north-western India. By 1993, the weed had developed resistance to isoproturon, a herbicide which had delivered effective weed control for 15 years. The short-term solution, implemented before the ACIAR project commenced, involved identification and registration of a new set of herbicides. But these new herbicides were expensive. To ensure high adoption they needed to be combined with changes in wheat-growing techniques that would provide cost savings to help farmers pay for them. And to avoid the re-emergence of...

Ano: 2002 URL: http://purl.umn.edu/47696 Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Haryana, India AgEcon Erenstein, Olaf; Malik, R.K.; Singh, Sher. This study documents the adoption and impacts of zero-tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State primarily drawing on a detailed empirical survey of 400 rice-wheat farmers. Our random stratified sample revealed 34.5% to be ZT wheat adopters and a quarter of the wheat area in the surveyed communities to be under ZT. The study suggests the potential for further diffusion but also flags the issue of disadoption (10%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values.

This study has evaluated the technical efficiency of farmers engaged in rice-wheat cropping systems in North-eastern India, who are using Resource-Conserving Technologies (RCTs) such as Zero Tillage (ZT) and Direct Seeded Rice (DSR). These technology promotions are being carried out under the intervention of the Cereal Systems Initiative for South Asia (CSISA) project, primarily funded by the Bill and Melinda Gates Foundation. The resource-conserving technologies are being promoted as part of conservation agriculture supported by the project. The data used in this study have been derived from the socioeconomic surveys conducted in Eastern Uttar-Pradesh and Bihar in North-eastern India during the kharif season of 2009 and rabi season of 2010.

Ano: 2007 URL: http://purl.umn.edu/91874 Assessing the Impact of International Natural Resource Management Research: The Case of Zero Tillage in India's Rice-Wheat Systems AgEcon Laxmi, Vijay; Erenstein, Olaf. A conservative ex-ante assessment of supply-shift gains alone (excluding social and environmental gains), shows that the investment in zero tillage (ZT) R&D by the Rice-Wheat Consortium and CIMMYT was highly beneficial with a benefit-cost ratio of 39, a net present value of US$ 94 million and an internal rate of return 57%. Sensitivity analysis highlights the influential role of the yield gain, the contribution of reduced tillage (i.e. partial adoption) and the assumed time-lag. Significant positive spillovers of sunk ZT R&D costs – both previous and from elsewhere - also contributed to the high returns. The case thereby highlights the potential gains from successful technology transfer and adaptation. The case however also underscores that...

Ano: 2006 URL: http://purl.umn.edu/25694 Root abundance of maize in conventionally-tilled and zero-tilled soils of Argentina Rev. Bras. Ciênc. Solo Taboada,Miguel Angel; Alvarez,Carina Rosa. Maize root growth is negatively affected by compacted layers in the surface (e.g. agricultural traffic) and subsoil layers (e.g. claypans). Both kinds of soil mechanical impedances often coexist in maize fields, but the combined effects on root growth have seldom been studied. Soil physical properties and maize root abundance were determined in three different soils of the Rolling Pampa of Argentina, in conventionally-tilled (CT) and zero-tilled (ZT) fields cultivated with maize. In the soil with a light Bt horizon (loamy Typic Argiudoll, Chivilcoy site), induced plough pans were detected in CT plots at a depth of 0-0.12 m through significant increases in bulk density (1.15 to 1.27 Mg m-3) and cone (tip angle of 60 º) penetrometer resistance (7.18 to 9.37...
