Characterization of Research Nodes : an integrative approach through indexing
Appropriate understanding of situation is pre-requisite for effective implementation of a development programme or scheme. One of the serious drawbacks in failure of most of the developmental efforts (government, ...
Rainfall risk and the potential of reduced tillage systems to conserve soil water in semi-arid cropping systems of southern Africa
(AIMS Press, 2016)
Improvement of household food security in the Limpopo Basin has been elusive due to a combination of factors related to information and market constraints, but also farmers’ risk aversion induced by the high variability ...
Effect of different mulching materials on maize growth and yield in conservation agriculture systems of sub-humid Zimbabwe
(AIMS Press, 2016)
The introduction of conservation agriculture (CA) for smallholders increased the competition for crop residues between crop and livestock enterprises of the mixed smallholder farming system. Smallholders practicing CA have ...
Mapping smallholder wheat yields and sowing dates using micro-satellite data
Remote sensing offers a low-cost method for developing spatially continuous crop production statistics across large areas and through time. Nevertheless, it has been difficult to characterize the production of individual ...
Predicting Rift Valley fever inter-epidemic activities and outbreak patterns : insights from a stochastic Host-Vector Model
(Public Library of Science, 2016)
Rift Valley fever (RVF) outbreaks are recurrent, occurring at irregular intervals of up to 15 years at least in East Africa. Between outbreaks disease inter-epidemic activities exist and occur at low levels and are maintained ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
Land use and agricultural change dynamics in SAT watersheds of southern India
(Current Science Association, 2016)
Impact of dynamic land use and land cover changes on the livelihood of local communities and ecosystem services is a major concern. This is particularly evident in most dryland agricultural systems in South Asia. We study ...
Evaluation of the effects of mulch on optimum sowing date andirrigation management of zero till wheat in central Punjab, India using APSIM
Machinery for sowing wheat directly into rice residues has become more common in the rice-wheatsystems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers nowpotentially able to access ...
The evolution of the MasAgro hubs : responsiveness and serendipity as drivers of agricultural innovation in a dynamic and heterogeneous context
(Taylor & Francis, 2016)
Little is known about effective ways to operationalize agricultural innovation processes. We use the MasAgro program in Mexico (which aims to increase maize and wheat productivity, profitability and sustainability), and ...
Field-scale modeling of tree–crop interactions : Challenges and development needs
(Elsevier Masson, 2016)
Agroforestry has attracted considerable attention in recent years because of its potential to reduce poverty, improve food security, reduce land degradation and mitigate climate change. However, progress in promoting ...
