The study was conducted under pot experimental conditions with Alluvial-meadow soil. The aim of the trial was to evaluate the effect of different nitrogen, phosphorus, potassium, and silicon fertilizer rates in the soil and their impact on the uptake of basic macronutrients with sunflower (Helianthus annuus L.) biomass. The experiment included 16 variants of increased fertilizer rates in 3 replications. Data on the yield of fresh and absolutely dry biomass from the aboveground part of plants and on the content of N, P, K, Si, Ca and Mg in the dry biomass was obtained. According to the data obtained, the content and uptake of the examined macroelements with the sunflower biomass were significantly influenced by the rates and fertilizer combinations. The highest uptake of nitrogen was in the variants with the following rates: N200, N300, and N400. The changes in the macroelementsβ uptake followed the changes in the quantities of the relevant elements in dry biomass in the variants of the experiment. By increasing the fertilizer rates the content of N, P, and Si, and their uptakes with sunflower biomass was increased. This trend with potassium was expressed to a lower extent.ΠΡΠΎΠ²Π΅Π΄Π΅Π½ΠΎ Π΅ ΠΈΠ·ΡΠ»Π΅Π΄Π²Π°Π½Π΅ Π² ΡΡΠ»ΠΎΠ²ΠΈΡΡΠ° Π½Π° ΡΡΠ΄ΠΎΠ² ΠΎΠΏΠΈΡ Π²ΡΡΡ

A three-year field experiment with maize was carried out on fluvisol. The aim of the present study was to evaluate the impact of biochar on maize yield at different levels of water stress and its effect on the amount of soil microorganisms. The following variants were studied: control with no biochar addition, and variants with biochar. Biochar was applied in 2 t/ha in 2016, produced by pyrolysis of rice straw, then in 3 t/ha in 2017 and 10 t/ha in 2018, both obtained by pyrolysis of oak bark. These variants were divided into three more depending on the irrigation regime: i.e. non-irrigated, irrigation at dT>0 Β°C, and irrigation at dT0 ΠΈ ΠΏΠΎΠ»ΠΈΠ²Π΅Π½ ΠΏΡΠΈ dT<-1.

A field study with spring barley (Hordeum vulgare L.) was conducted on the area of long-term balance experiment in Tsalapitsa village near Plovdiv (Bulgaria), on alluvial-meadow soil. Mineral fertilization was not applied to this crop in order to equalize the area regarding nutrient content. The crop grown before barley was maize with 4 variants of fertilization and one control variant: N0P0, N100Π 50, N150Π 100, N200Π 150, and N250P200. The present study aimed to evaluate the productivity, content and uptake of macronutrients (N, P, K, Ca and Mg) with the biomass of barley, grown as aftereffect. Due to the fertilization of the previous crop, different residual amounts of nutrients in soil lead to significant variability in barley yields. The highest grain yield was obtained in variant N250P200 - 3978.8 kg/ha, approximately four times higher than the yield in the control. Nitrogen content in the grain of barley is also influenced by the variants, being the lowest in the control - 1.25%, and the highest in variants N250P200 and N200P150 - 2.13% and 2.09%, respectively. The variability of P, K, Ca and Mg contents by variants is lower. With the total biomass of barley, depending on the variants of the experiment, between 23.2 - 132.7 kg N/ha; 26.6 - 146.3 kg K/ha and 9.3 - 36.5 kg P/ha were exported from the field. A good regression relationship was found between barley grain yield and nitrogen export with the total biomass (R2 = 0.859, Pβ€0.001).ΠΡΡΡ
