The research was conducted during 2012-2014 to the crop of rye, in the sandy soils condition from southern Oltenia, and focused radicular and foliar fertilization effect on the quantity and quality of production of rye. Rye crop was located on a sandy soil, poorly stocked as nitrogen (0.06 to 0.07%), well stocked in extractable phosphorus (65 ppm and 81 ppm) and low to medium stocked in exchangeable potassium (37 ppm and 131 ppm). The results obtained to rye, about the quantity and quality of grain yield at harvest, highlights the experimental variant in which was applied a radicular fertilized with N150P80K80 + two foliar fertilizations with Green Plant, which is composed N9-P45-K15 + 6 microelements (first treatment - early spring at the beginning of vegetation in concentration of 0.5% and the second treatment during the formation of the straw, in concentration of 1%), where there was a maximum production of 4278 kg / ha and a content balanced in grain protein (12, 3%) and gluten (26.7%). The radicular fertilization with NPK, has determined to obtain a production increase of 113.5%, compared to unfertilized and the foliar fertilization has led to increased production by 23%, compared to foliar unfertilized.
