Abstract
Usually, the success of growing is determined by the quality and market value of vegetables. The quality commodity production is also expected by the market. The really good vegetable contains a number of biological nutrients that are easy to process and easily digestible and it can provide culinary delights for the consumer. In Hungary the cultivation of carrot ( Daucus carota L.) has a centuries - old tradition, but often raises the question as to the most effective nutrient supply technology during its growing. According to this, the determination of the correct nutrient supply and the selection of the variety are professional challenges. Our aim was analyzing and presenting the different variety - based nutrient supply methods based on small size parcels. At the end of our observation we determined the biochemical mechanism of the uptake of several nutrients and their agrochemical importance in correlation of nutrient supply methods and the meteorological and soil condition of the cultivation area. Our further aim was analyzing and justifying the most effective nutrient supply of Napa F 1 carrot hybrid.
Highlights
Considering its carnitine, carbohydrate and volatile oil content the carrot is (Daucus carota L.) one of the most valuable vegetables
The sweet, pleasant taste of the carrot is given by the mono- and disaccharides (Kovács and Géczi, 2011)
The results of our laboratory investigations were evaluated in the range of security intervals 95%, N = 3; p = 5% (Diagram 1.) Based on laboratory investigation we found that the effect of organic manure and fertilizer without other nutrient supply did not create significant difference in producing carotene substances in carrots
Summary
Considering its carnitine, carbohydrate and volatile oil content the carrot is (Daucus carota L.) one of the most valuable vegetables. The five most important carotenoids are: beta-carotene, the α-carotene, beta-kryptoxanthin, lutein and lycopene (Linus Pauling Institute, 2009). In addition to carotenoids the carrot contains lycopene and xanthophyll; they are well-known about antioxidant action. Carrots contain calcium, iron and phosphorus in important concentration. Another value-added material of carrot is the carbohydrates. The water- soluble carbohydrates (WSC) in the carrot are the fructose, sucrose and glucose, which form energy reserves in the carrot. Fiber materials of carrot are mainly cellulose, and to a lesser extent, hemicellulose and lignin. They determine the mass of the carrot root that is the yield in economic terms (Schuh, 2011). In case of every cultivated plant, to reach the expected yield for a given variety, we must determine the optimal water, nutrient and other ecological claim of the plant by previous testgrowing, we must use the most prominent nutrient supply technology for cultivation (Lantos, 2016)
