2.1. Real GDP growth averaged 11.2% per annum during the 2003/04 and 2008/09 period, placing Ethiopia among the top performing economies in Sub-Sahara Africa. This growth performance is well in excess of the population growth rate and the 7 percent rate required for attaining the MDG goal of halving poverty by 2015. Yet, a number of issues warrant the attention of policy makers. 22.2. Ethiopia’...

A number of significant annual weather variables are known to be critical to the quantity and quality of vineyard harvest. In rain-fed viticulture regions for example, most quality wines are produced in areas where the annual precipitation is below 700 to 800 mm (Jackson and Shuster, 1987; Galet, 1993). Indeed, barring any moisture stress to the vine, a warm, dry growing season is generally ass...

Moth bean and guar are important rain-fed crops of the western arid region India. The genetic improvement mostly realized through germplasm evaluation selection has successfully increased yield potential stability. However, continued been hampered due to inefficient or non-availability crossing techniques for recombination breeding. We attempted direct pollination without emasculation found it ...

Background Climate change is gaining importance as scientific and socio-economic studies have brought forth substantial evidences (American Meteorological Society 2012; Norris et al. 2008; Agrawal and Perrin 2008; Paavola 2008; IPCC 2014; UNFCCC 2007; Adger and Kelly 1999). The impact of climate change is more likely to have an adverse effect in the developing countries due to high dependency o...

Harvesting rain-fed chickpeas (Cicer arietinum L.) from fallow fields in developing countries is currently a manual process performed by laborers in a tedious manner at a low level of efficiency. A tractor-pulled harvester was built in which a chain conveyor transfer harvested material. A tractor-mounted harvester was then redesigned, which incorporated a modified stripper header to detach pods...

In the definition by Kerr, 2002, watershed is “an area from which all the water drains to a common point”. There is therefore an interest in creating infrastructures that allow to store this water so that rain fed crops do not need to rely so heavily on the weather conditions, mainly in drought-prone regions. In rural areas where farming is the main livelihood, even slight variations in climate...

to investigate the effect of supplemental irrigation and nitrogen fertilizer on kernel weight, test weight and wheat grain yield under dryland conditions, a two-year field experiment was conducted in the research farm of college of agriculture, shiraz university during 2004-2005. five irrigation regime including dryland conditions, irrigation at stem elongation, booting, flowering and grain fil...

the sunn pest, eurygaster integriceps puton, is a serious pest of wheat in coraim region of ardabil province. in this study, the egg parasitoids of sunn pest was collected and identified in this region during 2007 and 2008. also, the percentage of egg parasitism was determined in 14 different defined areas in this region. the areas 1-3 were selected in irrigated wheat fields in the presence of ...
