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...
'Here is bread, which strengthens man's heart, and therefore called the staff of life' Introduction The number of plant species which nourish humanity is remarkably limited. Most of the 195,000 species of flowering plants produce edible parts which could be utilized by man; however less than 0.1% or fewer than 300 species are used for food. Approximately 17 plant species provide 90% of mankind'...

How will Conversion to Organic Cereal Production Affect Carbon Stocks in Swedish Agricultural Soils?
Soil carbon changes were modelled over 30 years with the focus on cereal crops, since leys are often managed similarly in organic and conventional agriculture. Other crops were not considered due to difficulties in large-scale cropping of oilseed rape and potatoes organically because of pest problems. Four scenarios were used: 0%, 8% (current), 20% and 100% organic cereal production. Conversion...
Grain production is one of the Ukrainian agro-industrial complex main branches. An indicator of the grain production efficiency is its profitability. It is characterized by significant annual fluctuations that induce risk. Redistribution of existing grain crops areas taking into consideration their profitability can bring to increase of production efficiency. The paper observes Markowitz’s opti...
Five major cereals such as wheat, rice, maize, barley and sorghum were among the first Neolithic crops that facilitated the establishment of the early agricultural societies. Since then they have remained the staple source of calories for the majority of the human population. Ample archaeological and molecular evidence has provided important insights into the domestication history of cereals bu...
