Влияние органических и минеральных удобрений на накопление азота, фосфора и калия в надземной части люцерны при покрытом посеве

The problems of impact of organic and mineral fertilizers on gathering of total nitrogen, phosphorus and potassium in the lucerne surface mass in coating planting of the grey-meadow soils which are weakly provided with the nutrient under the condition of Karabakh region were commented. Provision of plants with the main nutrient during the vegetation, productivity, crop quality depends on supply of the nutrient which is easily assimilated. In order to get high yields from agricultural plants, the organic and mineral fertilizers must be applied to a norm which was fixed on the basis of soil cartograms, the cultivation agrotechnics must be correctly fulfilled every year. The good food regime for the lucerne depends on optimization of fertilizer norms in different irrigation. The highest quantity of total NPK was observed in the first mowing, but it reduced in the next mowing’s. Nitrogen and potassium is high in each of the mowing’s, but phosphorus is little on the surface mass. This is due to increase of the nutrient quantity of lucerne and soil fertility. This positively influences on nutrient regulation on the surface mass over the mowing’s in lucerne plant.
