Abstract. The development of optimal nutritional system for agricultural crops is one of the main factors for the getting of stable yields. The deficiency of some macro- and microelements in plant nutrition, leading to yield decreasing, can be compensated with new complex of balanced fertilizers and biological products. The aim of the work is to study the effect of nitrogen fertilization, new forms of complex fertilizers based on active biological substances (“Kodamin B-Mo”, “K-Gumat-Na”, “Agroflorin” “Auksinolen”) and the microbiological preparation (MBP) “Bisolbifit” on the yield and quality of grain of fodder winter rye “Novaya Era” on sod-podzolic soils in the Pskov region. The originality is that for the agro-ecological conditions of the Pskov region, the influence of new complex fertilizers, biological and humic preparations in the cultivation of winter rye has been studied. Methods. The research was carried out in 2019 on the experimental field of the laboratory of agricultural technologies of the Federal research center for Bast Crops (Pskov Department). The records, observations and analyzes were carried out according to generally accepted methods. Results. The maximal positive effect on grain yield was made with the introduction of complete mineral fertilizer in doses of N80P40K70 with fractional nitrogen application: 20 kg of active substance – in the main fertilizer, 40 kg – in the tillering phase and 20 kg – in the booting phase. Up to 1,3 t/ha or 42.2 % to the control level were obtained in that variation. Application of mineral fertilizers in a dose of N40P40K70 and MBP “Bisolbifit” increased on 0,4 t/ha of grain, which amounted 10.6 %. Foliar double treatment of plants with fertilizer “Kodamin B-Mo” increased grain yield up to 8.6 %. The influence of the investigated factors on the protein content and nitrate nitrogen in plants of fodder winter rye, the weight of 1000 seeds and the structure of the yield was established. For 1 kg of active substance of mineral fertilizers at various doses of nitrogen fertilizing the additional yield of grain from 3.68 to 6.39 kg was obtained.

Maize Fertilization

The response of crops to the application of biofertilizers in the soil is not yet well established. Therefore, we carried out this study with the objective of evaluating the productive potential of maize fertilized with doses of sewage sludge, comparing with the use of mineral fertilizer over four agricultural seasons. The experiment was conducted in a Red Dystroferric Nitosol (Ultisol) in a randomized block design and repeated measures in time. The treatments consisted of five doses of sewage sludge and one treatment using nitrogen, phosphorus and potassium in formulation. All fertilizations were carried out at maize sowing at four planting times (summer and 2nd crop of 1st agricultural year and, summer and 2nd crop of 2nd agricultural year) and replicates. The results showed a cumulative increase in the P, Ca, Mg and Zn leaf concentrations over the four seasons crops, when the sewage sludge was used in the 30 and 40 Mg ha-1 doses. However, reductions in plant height, weight and maize cob diameter, mass and grain yield were observed at the end of the last harvest. The treated sewage sludge is a viable alternative for maize fertilization in the first harvest, provides increases in grain yield in the order of 1.35 Mg ha-1 and can be recommended instead of NPK mineral fertilizers in built-up fertility soils.

Integrated Nutrient Management

Integrated nutrient management (INM) effects chemical transformation of nutrients in soil and plant uptake. This study present the long-term (30 years) effects of integrated nutrient management on zinc (Zn) fractions and rice yield. The treatments include ten combinations of nitrogen, phosphorous and potassium applied through mineral fertilizers and substituted through farmyard manure (FYM), green manure (GM) and wheat cut straw (WCS).The distribution of Zn into exchangeable (EXCH), carbonate bound (CARB), organic matter bound (OM), manganese oxides bound (MnOX), amorphous iron oxide bound (AFeOX) and crystalline iron oxide bound (CFeOX) was determined. The effect of long-term use of mineral fertilizers on EXCH-Zn was not significant as compared to control, however, EXCH-Zn increased significantly in INM treatments compared to both control and mineral fertilizer in surface soil (0-15 cm). Similarly, CARB-Zn and OM-Zn was significantly higher in INM as compared to control and mineral fertilizer treatments. The distribution of Zn in MnOX, AFeOX and CFeOX fractions was not distinctly affected with long-term fertilizations. In general, concentration of Zn fractions was lower in subsurface soils (15-30 cm) as compared to surface soils. The grain yield of rice increased in order control< mineral fertilizers <INM treatments. The highest grain yield (71.8 q ha-1) was recorded in INM treatment where 25% of the recommended NPK were supplied through GM. The positive and significant correlation of EXCH-Zn (r = 0.714), CARB-Zn (r = 0.601) and OM-Zn(r = 0.648) fractions and Zn uptake in grain showed that the plant availability of Zn depends upon these fractions in soils.

The results of the influence of pre-sowing seed treatment, the main application of mineral fertilizers and foliar fertilizing with ammonium nitrate, urea, organo-mineral fertilizer D2 or bacterial preparation Escort-bio on the formation of productivity and quality of spring wheat of the Elegia mironovskaya variety are presented. Experimental investigations were carried out on the Chernozem of the South during 2014-2016. In the conditions of the educational, scientific and practical center of the Nikolaev NAU. The results of research showed that the introduction of nitrogen-phosphorus fertilizers before sowing and foliar fertilizing of spring wheat crops on average over three years provided an increase in grain yield by 1.00–1.58 t/ha in variants with water treatment of seeds and by 1.08–1.72 t/ha when processing seeds with microbial preparation Escort-bio. Pre-sowing treatment of escort-bio seeds contributed to the additional production of 0.14–0.28 t /ha of grain, depending on the fertilizer option. The highest grain yield was formed by applying N30P30 for pre-sowing cultivation, treating seeds with a microbial preparation and carrying out the phase of plant exit into the tube of feeding with ammonium nitrate with a dose of N30. Pre-sowing treatment of escort-bio seeds and foliar fertilizing contributed to an increase in the payback of fertilizers by increasing the yield of spring wheat. The maximum specified indicator is determined by the background of bacterial seed treatment, the main application to the sowing of N30P30 and carrying out two top-UPS with organo-mineral fertilizer D2 or Escort-bio. Application of fertilizers and foliar top-UPS on average over three years increased the protein content of spring wheat by 0.7–1.4 %, and gluten – by 1.2–1.9 %. The maximum both indicators of grain quality are determined in the version of the main application of N30P30 with making-up at the beginning of the earing phase with urea at a dose of N30 –14.9 and 28.1 %. The conditional yield of protein and gluten from a hectare of spring wheat sowing with an improvement in the background of plant nutrition grew and reached maximum values in the variants of N60P30 before sowing or N30P30 before sowing with fertilizing with ammonium nitrate at a dose of N30 in the phase of exit to the tube.

The aim of this study was to examine the impact of the application of mineral fertilizers with a high content of phosphorus and potassium on the productive characteristics of some small grains grown on pseudogley soils. The research was carried out in the vicinity of Kraljevo during the period 2011/2013. The experiment included wheat, winter barley and triticale and 3 variants of fertilizers (K ? control; V1 ? N80 P60 K60; V2 ? N80 P80 K80 and V3 ? N80 P100 K100). In addition to grain yield, absolute mass and hectoliter mass were observed. The obtained results were analyzed using the analysis of variance. There were no significant differences in yield, absolute mass and hectoliter mass of the grain between small grains. The use of fertilizers with an increased content of phosphorus and potassium led to a significant increase in grain yield, absolute mass and hectoliter mass of small grains compared to control. Among the variants V1 and V2, and V2 and V3 variants, there were no statistically significant differences in the absolute mass and hectoliter mass of the grain. The average values of grain yield of small grains ranged from 1510 kg ha-1 in the control variant up to 3209 kg ha-1 in the variant with the highest dose of phosphorus and potassium fertilizers. Significant differences in grain yield were observed between the variants V1 and V2, as well as between the variants V2 and V3. The application of only mineral fertilizers on acid soils leads to relatively low yields.

The Cost

Soybean is the most commercially cultivated crop in Paraguay, and obtaining high yields requires the application of large amounts of fertilizers, raising the cost of production. Developing strategies for the efficient use of applied nutrients is necessary. Therefore, the study aimed to evaluate the agronomic efficiency of combinations of mineral fertilizers with organic matter and rock powder in the development, nutrition, and yield of soybean. The experiment was carried out in Hernandarias, Paraguay, in the 2016-2017 harvest. The different fertilizers influenced the absorption of Zn, Mg and K, and grain yield. Among the treatments, the highlight was the agronomic efficiency index obtained by the replacement of 30% of mineral fertilizer by humus, presenting grain yield of 3219, 67 kg ha-1. However, it was equal to the mixing 30% of humus + rock powder with 70% of NPK formulation 04:40:10 with grain yield of 3206.50 kg ha-1, and the mixing 20% of humus + rock powder with 80% of NPK formulation 04:40:10 with grain yield of 3165.17 kg ha-1. Thus, it is recommended to use rock powder and humus in soybean production in Paraguay, especially in Latossolos (Oxisols) that have little organic matter and low CTC.

Fertilizer Effect

Grain yield stabilization of lowland rice over cropping seasons was explored using different compositions of inorganic fertilizers (NPK, NPKCa, NPKMg, NPKZn, NPKCaMg, NPKCaZn and NPKCaMgZn) and straw incorporation (3, 6, 9, 12 and 15 tha-1 ). No fertilizer and no straw amended plot was the control in a split-plot design with three replications laid in a Fluvisol of Guinea savanna in Centre Cote d’Ivoire. Three weeks old nursery rice variety NERICA L19 was transplanted. No significant difference of grain yield was observed between the different treatments excluding the highest yields recorded for treatments NPKMg (5.09 tha-1 ), NPKZn (5.15 tha-1 ) and NPKCaéMg (5.31 tha-1 ) compared with 12 (3.95 tha1 ) and 15 tha-1 (4.14 tha-1 ) as straw rates respectively. Grain yield declining trend was more pronounced for mineral fertilizer treatments showing twice greater depressive effect of cropping cycle compared with the straw especially, for treatments characterized by highest grain yield in the first cropping season and similar grain yields were recorded for both sources of nutrient in the third cropping cycle. Of slowness of nutrients releasing by straw, highest grain yield was expected for this soil amender within a longer period of cultivation whereas, unbalance soil micronutrients should be relevant to studious declining yield under inorganic fertilizer effect. Nevertheless, the straw rate of 12 tha-1 supplying 0.58% of NPK as mineral fertilizer equivalent can be recommended for sustaining lowland rice production in the studied agro-ecosystems unless for three cropping seasons.

The Given

The results of studies of the change in redox potential in the profile of light gray forest surface-gleyed soil on variants with long-term agricultural use without applying fertilizers and mineral fertilizer system solely compared with the soil under the forest are presented. On the basis of the conducted analyzes it was established, that soil tillage without fertilizer application and with mineral fertilizer solely has a different effect on ROP in the profile. In the soil without fertilization (control) as compared to the forest a moderate oxidizing (514 mV) and slightly oxidizing (437 mV) processes are happening. Prolonged application of mineral fertilizers to the soil (N65R68K68) significantly reduced the redox potential of all genetic horizons compared with forest and control without fertilizers. For the given fertilizer system the highest values of ROP were obtained in arable HEgl and underarable HEgl layers: 426 mV and 416 mV respectively. Redox potential sharply decreases with the depth to 398-311 mV, which characterizes processes occurring in the soil profile, as weakly reducing and close to moderately reducing.
