Impact of zero tillage in India's rice-wheat systems
(CIMMYT / RWC, 2007)
Zero tillage impacts in India's rice-wheat systems: A review
To date, the most widely adopted resource conserving technology in the Indo-Gangetic Plains (IGP) of South Asia has been zero-tillage (ZT) wheat after rice, particularly in India. The paper reviews and synthesizes the ...
Specification effects in zero tillage survey data in South Asia's rice-wheat systems
Specification effects in terms of how technology options are contrasted can introduce bias in impact assessment. In a companion paper we evaluated the on-farm impacts of zero tillage (ZT) wheat as a resource-conserving ...
Labranza de conservación o conservación de residuos? Una evaluación del manejo de los residuos en México
La clave de la labranza de conservacion es el uso de los residuos como mantillo. Sin embargo, existe mucha confusion en relacion al termino labranza de conservacion, entre otras cosas por poner demasiado enfasis en la ...
Comparing water management in rice-wheat production systems in Haryana, India and Punjab, Pakistan
The intensive irrigated rice-wheat systems in the northwest Indo-Gangetic Plains of South Asia are built on a long tradition of canal irrigation and the more recent advent of tubewells. Findings from farm surveys are used ...
Factors affecting the adoption of zero tillage wheat in the rice-wheat systems of India and Pakistan
Zero tillage planting of wheat after rice has been the main success in the quest for resource-conserving technologies that can save water, reduce production costs and improve production in the Indo?Gangetic Plains, the ...
A survey of factors associated with the adoption of zero tillage wheat in the irrigated plains of South Asia
There is a quest for resource-conserving technologies that can save water, reduce production costs and improve production to address the slow down in productivity growth in the Indo-Gangetic Plains, the cereal bowl of South ...
Triangulating technology diffusion indicators: Zero tillage wheat in South Asia's irrigated plains
Impact assessment hinges on reliable indicators of technology uptake, but this poses particular challenges for new agronomic practices in emerging economies. This paper presents a triangulation approach to assess technology ...
Conservation agriculture in mixed crop-livestock systems: Scoping crop residue trade-offs in Sub-Saharan Africa and South Asia
Conservation agriculture (CA) is being advocated to enhance soil health and sustain long term crop productivity in the developing world. One of CA's key principles is the maintenance of soil cover often by retaining a ...
