Effects of surface and subsurface drip irrigation regimes with saline water on yield and water use efficiency of potato in arid conditions of Tunisia
Field experiments were conducted on a sandy soil during spring of 2009
and autumn of 2010 in southern Tunisia for evaluating the effects of two drip
irrigation methods and three irrigation regimes on soil moisture and ...
The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status ...
Challenges in the Dryland Agricultural Production Systems of South Asia: Research Priorities and Strategies
Dryland (arid and semi-arid) ecosystems occupy more than 41% of global land area and are home to 2.5 billion people. More than 50% of South Asia’s dryland ecosystems are located in India. Drylands contribute about 40% of ...
Analysis of Oil Content in Jatropha by Nuclear Magnetic Resonance Spectrometry
Thirty two diverse Jatropha curcas L. cultivars were analyzed for their oil content by the standard Soxhlet extraction method using
hexane as solvent. The results were then compared with those obtained by nuclear magnetic ...
Spearheading Development through Empowering Smallholder Farmers along Beef Cattle Value Chains: a Case of Goromonzi and Murehwa Districts, Zimbabwe
Smallholder beef subsector can potentially contribute to the nation’s development. The paper presents the
results of the value chain analysis of the beef sub sector in Zimbabwe. Data was gathered through cross

Assessing the Potential for Zone-Specific Management of Cereals in Low-Rainfall South-Eastern Australia: Combining On-Farm Results and Simulation Analysis
In the low-rainfall region of south-eastern Australia, distinctive soil types reflecting
the typical landscape of higher elevated dunes and swale zones at the bottom
can be found within one field. Different soil characteristics ...
Integrated Plant Genetic and Balanced Nutrient Management Enhances Crop and Water Productivity of Rainfed Production Systems in Rajasthan, India
Analysis of soils from 421 farmers’ fields in eastern districts of Rajasthan, India, revealed widespread deficiencies of sulfur (S; 43 to 87% fields deficient), boron (B; 25 to 100%), and zinc (Zn; 0 to 94%) in addition ...
Understanding farm trajectories and development pathways Two decades of change in southern Mali
Institutional support for smallholders has been themotor for the expanding cotton production sector in southern
Mali since the 1970s. Smallholder farms exhibit diverse resource endowments and little is known on how ...
