The world population is projected to increase by nearly 30 percent and reach 9.0 billion by 2050. Increasing competition for global protein is anticipated due to this burgeoning population and from the rising demand for food and protein that is a consequence of economic development and higher income in emerging economies, most notably India and China. It has been estimated that the world’s farm...

Optimizing the productivity and efficiency of cereal–legume intercropping through exploiting differences in nitrogen (N) acquisition two crops is crucial Mediterranean areas. A two-year field study was conducted Central Italy to determine how N fertilization rate affected forage grain production as well a barley (Hordeum vulgare L.) bean (Vicia faba L. var minor) intercrop. Crops were grown mon...

Pediococcus species isolated from forage crops were characterized, and their application to silage preparation was studied. Most isolates were distributed on forage crops at low frequency. These isolates could be divided into three (A, B, and C) groups by their sugar fermentation patterns. Strains LA 3, LA 35, and LS 5 are representative isolates from groups A, B, and C, respectively. Strains L...

Recently, environmental quality issues related to sulfur (S) have made it necessary to reduce its release into the atmosphere in wet or dry forms, which in turn might influence the S requirement of crops. It is anticipated that by 2020, S deposition will decrease by up to 30% in eastern portions of Oklahoma and by 15% throughout the remainder of the state. This change calls for frequent monitor...

Alfalfa (Medicago sativa L.) is one of the most important forage crops used to feed livestock, such as cattle and sheep, and the sulfur amino acid (SAA) content of alfalfa is used as an index of its nutritional value. Aspartate kinase (AK) catalyzes the phosphorylation of aspartate to Asp-phosphate, the first step in the aspartate family biosynthesis pathway, and adenylylsulfate reductase (APR)...

Many of the major forage species used in agriculture are outcrossing and rely on the exchange of pollen between individuals for reproduction; this includes the major species used for dairy production in grazing systems: perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.). Cultivars of these species have been co-existing since contrasting cultivars were developed using ...

Forage crops cultivation area in Turkey is 2.312 million ha 2020. The rate of forage the total agricultural 6.1%, and its field land 12.3%. Lucerne, silage corn, oat, vetch, sainfoin are main Turkey. amount produced 16.8 tons hay 48.8 thousand seeds. crop areas have increased by 206% since beginning 2000s due to government subsidies. However, shortage quality roughage still a big problem for an...

The current emphasis on sustainable agricultural systems has led to a renewed interest in the use of cover crops to reduce soil erosion losses and retain soluble nutrients during the dormant season. Cover crop choices include a broad range of plant material, such as ryegrass (Secufe cereale L.), winter wheat (Triticum aestivum L.), forage grasses, and legumes. Historically, cover crops were use...
