RESEARCH ON THE INFLUENCE OF FERTILIZATIONS ON THE NUTRITIONAL QUALITY OF GRAIN SORGHUM IN THE CONDITIONS OF SANDY SOILS IN SOUTHERN OLTENIA

Abstract

Research conducted at SCDCPN Dăbuleni in the period 2018-2019, regarding the influence of the fertilization system on the nutritional quality of grain sorghum, has revealed different results, due to both the applied fertilization and the climatic conditions of the study period. The most balanced biochemical composition of sorghum beans was obtained in the fertilized variant with N150P80 K80 + biostimulatory (ALBIT-40 ml / ha) (11.72% humidity, 13.50% protein, 906.39 kg / ha protein, 6714kg / ha grain production, 3.53% fat, 87 kg / hl hectolitric mass, 29g mass of 1000 grains). The amount of protein expressed as a percentage increased with the increase of the production but insignificant, and the quantity of protein expressed in kg / ha increased with the increase of the distinct grain production significantly. Regarding the influence of the study years, the best results were obtained in the climatic conditions of the year 2018, which was characterized by maximum average temperatures of 26.6 0C, in the summer months and with significant precipitations during the period May-July (106.6-195.2mm)
