“…Quite apart from field workers, the farmers themselves often lack education and thus are excluded from some of the knowledge streams which provide information on conservation agriculture. Small scale itself can also be a constraint for the efficient utilization of much conservation agriculture farm equipment, e.g., zero till drills, which forces the commercialization of machinery provision services or the formation of farmer groups for resource/equipment sharingand each has attendant additional transaction costs (Laxmi et al, 2007).…”

“…In two years, in Haryana, over 100,000 h of wheat was planted this way. This led to a demand for the new planting equipment, a rise in sales of ZT drills and subsequently increase in ZT wheat in the IGP of South Asia (Hobbs et al ., 2008; Laxmi et al ., 2007; Rehman et al ., 2015).…”

SUMMARYThis paper follows the progress made in India for research and farmer adoption of conservation agriculture (CA) since the publication of Erenstein (2012), who contested the idea that zero-till (ZT) establishment of wheat in rice–wheat systems could be further developed into full CA systems. Data presented in this paper show that research has successfully found solutions for both the wheat and rice phases of the rice–wheat systems of the Indo-Gangetic Plains (IGP) in the past 8 years. It shows that by finding solutions in both the rice and wheat phases, yields, water use efficiency and profits increased, while labour needs reduced. Indian scientists have also confirmed these benefits in participatory on-farm research in various locations, both east and west regions of the IGP. Farmers see for themselves through experimentation that they get higher yields with less cost and with more efficient use of inputs and water. A key factor has been the development of improved seed drills with the help of Indian private sector manufacturers of agricultural equipment. Indian scientists have also successfully conducted CA research on several other crops and in other regions besides the IGP. The paper shows that it is better to introduce parts of the CA management practices in a step-wise fashion first, rather than introducing the entire package at once since farmers first have to test and evaluate a new technology to understand how it benefits them personally before they will adopt it. The paper concludes that in the rice–wheat systems of South Asia, adoption of CA is indeed possible to achieve although it is still a work in progress. CA is a complex technology package and it takes time to overcome all of the contested issues mentioned in Erenstein (2012).

“…The objective of the paper is to assess how the assumed counterfactual case in terms of accelerating technology deployment affects various impact assessment indicators of adaptive agricultural research. The paper does so through the empirical case of zero tillage wheat in Indiarevisiting earlier work by Gupta (2007a and2007b). The subsequent section presents the underlying zero tillage case study and methods.…”

A critical assumption in the impact assessment of an agricultural R&D effort is whether the effort in question has a substitute-that is, whether the innovation would also happen under other settings. This paper takes the case of zero tillage wheat in India to explore diverging counterfactual scenarios whereby, in the 'without' case, the innovation would not have been introduced or would have been introduced only with a ten-year or five-year lag. The authors quantify how the assumed counterfactual scenario affects various impact assessment indicators. They show that, even when assuming a conservative five-year lag and based on induced supply-shift gains alone, the investment in zero tillage R&D by the international agricultural research system was highly beneficial. The ability of zero tillage to combine cost savings and yield gains, its wide applicability and significant R&D spill-ins contributed to the high returns. The case thus highlights the high potential gains from successful adaptive research, even if the main effect is only to accelerate technology deployment.
