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 ...
Cropping systems and crop residue management in the Trans-Gangetic Plains: Issues and challenges for conservation agriculture from village surveys
Conservation agriculture practices are being advocated to help sustain crop productivity gains and secure environmental sustainability in the Trans-Gangetic Plains, India?s Green Revolution heartland. The paper illustrates ...
Microsatellite marker-based diversity and population genetic analysis of selected lowland and mid-altitude maize landrace accessions of India
Maize (Zea mays L.) harbours significant genetic diversity not only in its centre of origin (Mexico) but also in several countries worldwide, including India, in the form of landraces. In this study, DNA fingerprinting of ...
Analysis of genetic diversity in the North Eastern Himalayan (NEH) maize landraces of India using microsatellite markers
Population DNA fingerprinting of 48 selected North Eastern Himalayan (NEH) landrace accessions was undertaken using 41 polymorphic fluorescent dye-labelled microsatellite/Simple Sequence Repeat (SSR) markers, using a DNA ...
Wheats for More Tropical Environments, A Proceedings of the International Symposium
This publication contains the proceedings of an international symposium on wheat production and research in tropical environments, held in Mexico on 24-28 September, 1984. In addition to the 43 contributed papers, it ...
Household inventories and marketed surplus in semisubsistence agriculture
A model of semisubsistence agriculture explicitly accounting for the ability of farm households to hold inventories of staple foods is developed. Comparative statics analysis highlights the potential importance of wealth ...
