ISSUES CONCERNING THE IMPACT OF FOLIAR FERTILIZATION ON THE PRODUCTION OF BARLEY IN TIMISOARA PUBLISHED

Fanel Constantin Tarjoc, Valeriu TABĂRĂ
The development of brewing industry in Romania draws to the development of agricultural industries that provide the raw material used in the process of obtaining this drink. One of the raw materials of great importance in this industry is barley. Starting from these considerations, the paper proposes a study of the evolution of production values recorded in some barley varieties under the influence of foliar fertilization products. This study is par of the author's doctoral research and is in progress to public sustaining of the doctoral thesis. The research method that we used involved the placement of experiences in the field and the development of physical and chemical laboratory analysis. Production values were obtained by statistical calculation. The biological material used is composed of several varieties of winter and spring barley. Bellow basic fertilization, foliar treatments were applied using the following products: PlantfertU, MicrofertU and TerraSorb. Have been studied both forms of spring and winter barley. Different physiological needs of both forms of barley have required the separate study of the effect of foliar fertilizer on them. In case of spring barley using the product PlantfertU we achieve the sustainable production of 2842 kg/ha for the Hanca variety and 2722 kg/ha for the Penellope variety. On winter barley best results are obtained using the product TerraSorb on Plaissant variety  (5490 kg/ha). Summing up the  results we can say that the best results were obtained using the foliar products foliar PlantfertU and TerraSorb, the difference being considerate statistically very significant compared with the results obtained using the product MicrofertU. Research related to the use of foliar fertilizers in barley cultivation have a high degree of novelty, the products that we used  being relatively newly introduced and used in Romanian agriculture. This fact gives a touch of originality on present work. The results have great significance in that they come in support of the barley growers who want to use new technological links in order to obtain high yields.
