Perehrym O. The formation of narrow-leafed lupin productivity depending on the sowing terms, seed rates and fertilization in the condition of Peredkarpatya

The thesis presents the results of three-year research study of the peculiarities of growth, development, formation of photosynthetic, symbiotic, individual and corn productivity of narrow-leafed lupin depending on the impact of seeding terms, seeding rates, norms of mineral fertilizers and outroot nourishment. The maximum yield of narrow-leafed lupine seed provides sowing during the first decade of April seeding rate of 1.1 million pcs./ha - 3.05 t/ha. Optimization of mineral nutrition of plants by means of application of mineral fertilizers norm P60K90 with the two foliar-applied Vuksalom Microplantom norm of 2 l/ha provides seed yield 3.22 t/ha. Higher crude protein in narrow-leafed lupin seeds was for sowing during the first decade of April and seeding rate of 0.7 million pcs./ha - 32.1 %, but the largest yield of crude protein obtained in the variant with seeding rate of 1.1 million pcs./ha - 0.94 t/ha. In the version of the introduction of the main mineral fertilizers norm P60K90 of holding two foliar-applied Vuksalom Microplantom norm of 2 l/ha the content of crude protein in narrow-leafed lupin seeds was 34.3 %, and collecting it's yield per unit area - 1.09 t/ha.
