applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...
Introduction of a suitable vetch as winter crop in cold drylands of Iran is highly important. Line VP-2670 with origin of Turkey was selected from ICARDA nursery during 2002 and was evaluated along with other selected lines and local checks over nine years in different stations and on-farm conditions. VP-2670 with mean 3500 kgha-1 dry biomass over environments, high stability and protein conten...
Line Yesevi-93 (cultivar Abidar) was first introduced to Dryland Agricultural Research Institute (DARI) through the International Winter Preliminary Barley Yield Trials (IWPBYT) in 1994. It was selected as one the most high yielding lines based on observational and statistical trails (Regional Barley Yield Trials) carried out in different locations during 1997-2000. The average yield of Abidar...

Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and...
this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...

Creating an Economic Linkage between Dryland Restoration and Carbon Sequestration 1.5. Carbon Offsets: What are They and How do They Help? 1.6. Validation and Verification of Carbon Stores 2. Increasing Carbon...
Improper use of natural resources, especially soil, causes its degradation and severe soil erosion. Water erosion is an important factor causing soil degradation. Land use change of pasture would result in severe soil erosion mainly due to the reduction of vegetation cover and also surface soil disturbance. The objectives of this study were to estimate the amount of sediment, runoff and nutrien...
There have been many studies of the diverse impacts of invasions by alien plants but few have assessed impacts on water resources. We reviewed the information on the impacts of invasions on surface runoff and groundwater resources at stand to catchment scales and covering a full annual cycle. Most of the research is South African so the emphasis is on South Africa's major invaders with data fro...
