The role of informal farmer-to-farmer distribution in diffusion of new barley varieties in Syria
This study examines the role, structure and effectiveness of informal seed systems in the diffusion of new barley varieties. It uses data collected by tracing farmers who received new barley varieties and other farmers who ...
High genetic diversity revealed in barley collected from small-scale farmer’s fields in Eritrea
Remarkable morphological variation has been found within small Eritrean barley fields. Barley was collected from fields approximately 50 m(2) in size. Spike shape, type, and colour were observed to vary both between and ...
Effects of Green-stage Grazing on Rainfed Barley in Northern Syria. II. Yield and Economic Returns
The effect of a single grazing at the tillering stage on barley yield and economic returns was studied with two widely grown local landraces over five seasons at Tel Hadya and two seasons at Breda in northern Syria. In ...
Factors affecting the grain yield predicting attributes of spectral reflectance indices in durum wheat: growing conditions, genotype variability and date of measurement
The sources of variation (environment, genotype and date of measurement) of spectral reflectance indices describing biomass and its physiological status, and their potential use for providing accurate and non‐destructive ...
Effect of the proportion of Species on the Yield and Quality of Forage Mixtures, and on the Yield of Barley in the Following Year
Mixtures of legumes and cereals in various proportions (seed ratios) were evaluated in Northern Syria for forage production and quality and for yield of barley grain in the following year. Both a vetch-cereal and pea-cereal ...
The Role of Informal Farmer-To-Farmer Seed Distribution in Diffusion of New Barley Varieties in Syria
This study examines the role, structure and effectiveness of informal seed systems in the diffusion of
new barley varieties. It uses data collected by tracing farmers who received new barley varieties and
other farmers who ...
Differential responses of barley landraces and improved barley cultivars to nitrogen-phosphorus fertilizer
Barley is traditionally grown in the Mediterranean region as a dryland crop, invariably under drought-stressed conditions and often without inputs such as fertilizer. Following research that demonstrated the benefits of ...
Responses of a Forage Hay Crop to the Residual Effects of Nitrogen and Phosphorus Fertilizers in On-Farm Trials in Northern Syria
Fourteen on-farm sites used in barley fertilizer trials were retained for a second year and, without further fertilizer, sown with a mixed vetch/barley forage crop. Rainfall at the sites ranged from 149 to 451 mm, and ...
Effects of Green-stage Grazing on Rainfed Barley in Northern Syria. I. Tiller Production and Other Agronomic Characters
Effects of simulated and actual grazing at the tillering stage on tiller production and other agronomic characters were studied over a number of seasons at two sites in northern Syria with two local barley landraces. In ...
An Example of the Farming Systems Approach: The Fertilization of Barley in Farmer and Researcher Managed Trials in Northern Syria
Following a survey of fertilizer use on farmers' barley fields in northern Syria and very positive results from barley fertilizer trials on ICARDA research stations, a programme of researcher managed trials on farmers' ...
