Abstract
This study was conducted to determine the nutritional status of maize cultivated lands and maize plant in Sanliurfa province in term of selenium and micro elements. For this purpose, samples of soil and plants were taken from Sanliurfa province and Akcakale, Ceylanpinar, Harran and Viransehir districts. Texture, soil reaction, electrical conductivity, CaCO3, organic matter, available selenium, exchangeable iron, zinc, copper, manganese and boron analysis were done in the soil samples. Total iron, zinc, copper, manganese, selenium and boron content were determined in plants samples. According to results of soil and leaf analysis, nutritional problems in term of selenium have been determined in the lands of maize cultivation in all districts. Nutritional problem in term of zinc has been determined in only Ceylanpinar district, in term of copper has been determined in Ceylanpinar and Viransehir district. Considering the results of the work carried out in Sanliurfa; it is understood that effective fertilization programs, methods and fertilization time are extremely important. The quality and highly efficient production in the maize cultivation is related to balanced fertilization, addition of organic fertilizers and other technical applications.
Highlights
In the nutrition circle among human, plant and animal, the use of plant nutrient sources is important in animal feed, the use of animal nutrient sources is important in human nutrition
In the World, the maize production is in second place after sugar cane with production amount of 1 016 736 092 tons according to the year 2013 data
This study aimed to determination of the nutritional status of maize growing areas in the Center, Viransehir, Ceylanpinar, Harran and Akcakale districts of Sanliurfa province in terms of Se and micro nutrients by soil and leaf analysis; to compare the obtained results with the reference values and to determine the problems arising for various reasons
Summary
In the nutrition circle among human, plant and animal, the use of plant nutrient sources is important in animal feed, the use of animal nutrient sources is important in human nutrition. Maize is one of the important nutrients used as human food and animals feed. Maize has become the most important grain product used in the food industry of the modern world. Maize grain has become one of the most important silage plants in the world for ruminant animals in recent years with the development of silage techniques, together with being a good feed for single mussels and poultry in animal feeding. The intense consumption of cerealbased foods, which are poor in micronutrient, causes micronutrient deficiencies in humans and serious health problems associated with it (Welch and Graham, 2005; Cakmak, 2008; Cakmak et al, 2009) These important nutrients are Fe, zinc (Zn) and selenium (Se). There are many ecological factors limiting nutrient uptake conditions, the nutrient ions are available (Deliboran et al, 2014)
