Dynamics of Fertilizer Nitrogen Applied to Sweet Sorghum (Sorghum bicolor (L.) Moench) in the Semi-Arid Tropics
Although sweet sorghum is in focus as a promising multi-purpose crop in semi-arid tropical regions, information on optimum nitrogen (N) management remains rather limited. To determine and understand the N dynamics in sweet sorghum-soil ecosystem, we evaluated the N recovery of applied fertilizer in the Alfisol field during the 2009 and 2010 rainy seasons. Sweet sorghum was grown under six N rat...

متن کاملThe feasibility for replacement of urea with nitrogen nano-chelated fertilizer in olive (Olea europaea L.) orchards
Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...
متن کاملnitrogen fertilizer response of some barley varieties in semi-arid conditions in morocco
the west asia-north africa region, which is characterized by a typical mediterranean climate, is the center of origin of cereals, notably wheat (triticum spp.) and barley (hordeum spp). however, cereal production, which is primarily rainfed, is mainly constrained by drought due to the low rainfall accompanied by high temperatures. cereals have been tradi-tionally grown following a fallow period...
متن کاملExpounding the Value of Grain Legumes in the Semi- and Arid Tropics
Approximately 70% of the population in the semiand arid tropics reside in rural areas and depend on agriculture for their livelihood. Crop production is primarily focused on a few starchy staple crops. While this can ensure adequate calories, it inadvertently neglects the need for dietary diversity. Consequently, food and nutritional insecurity remains prevalent in the semiand arid tropics. We ...
