Au Niger Est, la faible disponibilité sur les marchés ruraux, la cherté et le faible pouvoir d’achat des paysans limitent l’application des engrais minéraux. L’objectif de cette étude est l’évaluation de l’effet du guano sur la production de la laitue. Le dispositif expérimental est un bloc complet randomisé avec dix-sept traitements issus de la combinaison entre 4 doses de guano, 2 doses de fumier et 2 doses d’engrais en trois (3) répétitions. Les paramètres étudiés portent sur les diamètres de pomme, la hauteur des parties aériennes, le développement foliaire et le rendement. Les résultats obtenus révèlent que le guano a un effet significatif sur la production de laitue. A la dose optimale 3,5 t/ha, le guano a permis d’augmenter la production de la laitue de 833 et 628% par rapport au témoin et aux parcelles ayant reçues uniquement la fumure minérale. La combinaison guano et fumure organique a permis d’accroitre le rendement par rapport aux parcelles fertilisées avec le guano seulement, tandis que l’apport de l’engrais minéral a un effet dépressif sur le rendement. Pour assurer une bonne production de laitue dans la cuvette de Balla, il serait préférable d’utiliser la combinaison guano (3,5 t/ha) avec du fumier. La préservation de la population de chauves-souris permettrait d’assurer la durabilité de la filière guano.Mots clés : Fertilisation, guano, laitue, cuvette oasienne, Gouré.   English Title: Guano, a natural organic fertilizer alternative to manure, tested on the production of green lettuce (lactuca sativa L.) in oasis of Balla (department of Gouré), Zinder, Niger In eastern Niger, low availability in local markets, high prices and low purchasing power of farmers limit the application of mineral fertilizers. The objective of this study is to evaluate the effect of guano on lettuce production. The experimental design is a randomized complete block with seventeen treatments resulting from the combination of four doses of guano, two doses of manure and two doses of fertilizer in three (3) replicates. The parameters studied for this experiment are: diameter of head, cabbage height of aerial parts, leaf development and yield. The results show that guano had a significant effect on lettuce production. At the optimum rate of 3,5 t/ha, guano increased lettuce production by 833 and 628% compared with the control and the plots receiving only the mineral fertilizer respectively. The combination of guano and organic fertilizer increased the yield compared to the plots fertilized with guano only, while the mineral fertilizer input had a depressive effect on yield. To ensure a good lettuce production in the Balla lowland, it would be better to use the guano combination (3,5 t/ha) with manure. Preserving the bat population would help ensure the sustainability of the guano industry.Keywords: Fertilizer, guano, lettuce, Oasis bassin, Gouré.

Organic fertilization in no-tillage system (NTS) has been used in regions milk production, in an order to provide nutrients for crops and provide a destination for high production of animal waste. The aim of this study was to evaluate the chemical attributes of an Oxisol, a function of organic fertilization with liquid manure from dairy cattle (LMDC) and mineral fertilizers. The experiment was conducted under NTS with crop rotation including legumes and grasses. The treatments were distributed in three randomized blocks with factorial arrangement, using three levels of mineral fertilizer (0, 50 and 100 % of the dose recommended for the crops) and four levels of organic fertilizer (0, 30, 60 and 90 m3 ha-1year-1). After six years of fertilizer management of crops, soil was collected from five depths (0-0.05, 0.05-0.10, 0.10-0.30, 0.30-0.50 e 0.50-0.80 m). The samples were determined the chemical pH, H++Al3+, Al3+, Ca2+, Mg2+, K+,electrical conductivity (EC), bases saturation (V), Ca2+/Mg2+ ratio, total organic C (TOC), B, Cl, Fe, Cu, Zn and Mn. The mineral fertilizers acidify the soil, raised the K+, P and EC and, changed the Zn and Cu contents. The organic fertilization with LMDC was a source of nutrients (Ca 2+, Mg2+, K+, P, Zn and Cu), raised the TOC and the EC, and kept the soil acidity attributes (pH, H++ Al3+ and V).

Lettuce (Lactuca sativa L.) production is a valuable crop for supporting family farms in the Brazilian semiarid region. The cultivation of this vegetable in a hydroponic system with foliar application of organic fertilizer can help in mitigating the challenges imposed by the region’s edaphoclimatic conditions. Therefore, it is important to increase the lettuce production using new technologies. VIUSID Agro® is an example of such technology that has the potential to increase lettuce yields. VIUSID Agro® is a natural compound that actives molecular processes without affecting the environment adversely. This product acts as a natural bioregulator and is basically composed of amino acids, vitamins, and minerals. The experiment’s objective was to analyze the impact of VIUSID Agro® organic fertilizer on the growth of hydroponic lettuce. The research was conducted on a family farm in Bom Jesus, Paraíba state, Brazil. The experimental was a completely randomized design with 5 VIUSID VIUSID Agro® concentrations (0.0; 0.2; 0.4; 0.6 and 0.8 mL L-1) and 15 replications. Among the indicators evaluated were the plant length, leaf number, stem diameter, root length, and fresh and dry biomass. The results showed that the 0.4 mL L-1 VIUSID Agro® concentration produced greater growth than the control (0.0 mL L-1) for variables analyzed plant length, fresh and dry biomass of aerial portion, root length, fresh and dry biomass of root. The foliar application of VIUSID Agro® improved the performance of the lettuce morphological characteristics in a hydroponic cultivation system. Although this is the first Brazil research evaluating VIUSID Agro® as an organic fertilizer in hydroponic lettuce, results have shown promise.

In order to meet the growing market of gerbera, it is necessary to develop studies that maximize its production, especially using organic fertilizer. In order to assess the nutrition and growth of potted gerbera conducted with mineral and organic fertilization, an experiment in a greenhouse was done, located at Western Paraná State University, Brazil. The experimental design was made in randomized blocks, with four replications and five treatments. The treatments were defined according to the source of fertilization, mineral (NPK) or organic. The organic fertilization were obtained by diluting in water four organic compost of poultry slaughter waste, obtained from in the composting process, in order to adjust electrical conductivity. The solution of the compost was used as organic fertigation, making the organic treatments. The liquid organic fertilizer, as well as irrigation of mineral treatment, was performed manually once a day. At the end of vegetative and reproductive periods, the levels of N, P, K, Ca, Mg and Fe were quantified in the plant tissue. At the same time, biometric parameters were assessed (number of leaves, plant diameter, leaf area, dry matter of aerial parts, number of heads, inflorescence dry matter, stem height, head diameter and diameter stem). The liquid organic fertilizers, obtained by composting procession of poultry slaughter waste, can be used as alternative source for potted gerbera nutrition, since they provide better or higher culture growth than the mineral fertilizer.

A comparative analysis of the seeds ash composition of the breed Rif (Brassica napus L.) rapeseeds grown in the Lipetskaya region was held. The plants were grown in the conditions of the agroecological experiment using mineral (NPK and zeolite) and organic (hen droppings) fertilizers. 6 variants of the experiment were studied – the plants are grown without fertilizers application (the control); the mineral fertilizer (N60:P60:K60) separately and together with zeolite (5 t.ha-1); the zeolite in pure form (5 t.ha-1); hen droppings (5 t.ha-1) separately and together with zeolite (5 t.ha-1). We studied the accumulation of 9 basic elements (in mass %) contained in Brassica napus. seeds ash using the method of energy-dispersive X-ray spectroscopy. The accumulation order of the elements was determined: P ≈ K > Mg ≥ Ca > Mo > S > Zn > Mn > Fe. The proportion of P fluctuated from 10.852 to 11.855 mass %; the proportion of K – from 9.933 till 12.343 mass %. The rapeseeds contained Mg, Ca, and Mo in similar concentrations within the range of 4.0 -5.8 mass %. The combined application of zeolite with organic fertilizer ensured the accumulation of the minerals in the seeds. Correlations between the elements were established. High correlation between elements K and Mo was found (r = 0.96); P and Mg (0.86); P and Fe (r = 0.94); C and Mo (r = 0.86). The positive effect of the combined organic-mineral fertilizers with poultry farms wastes usage on the mineral elements accumulation in rapeseeds was stated. It is noted that the accumulation of P, Ca, Mo, and S in rape seeds leads to a decrease in Zn.

Abstract The most effective doses of the modified organic-mineral fertilizer (MOF), produced from non-contact pig manure in the conditions of the Rostov region for the purpose of soil reclamation, were determined. Experimental studies were carried out to determine the most effective dose of MOF based on non-contact pig manure. The dependence of the spring wheat yield on the use of a modified organic-mineral fertilizer based on liquid waste from pig farms fermented bird droppings and mineral fertilizers is determined. The equivalence of the effect of a modified organic-mineral fertilizer based on liquid waste from pig farms and fermented bird droppings, introduced in an equivalent dose, on plant biomass was established. When comparing the effects of different types of fertilizers, their toxicity was not established. The introduction of a modified organic-mineral fertilizer based on liquid waste from pig farms at a dose of 2 t / ha provided the highest biomass yield of 34-day-old plants of spring wheat of the “Zlata” variety, which reached 0.9 g/vessel and was 28.5% higher than the control value. A new organic mineral fertilizer with a pH of 8-10, with an organic content of up to 73% per dry weight, can be used for supporting the quality of liming and improving soil.

Control Analysis

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

The Impact

The issue of scientifically sound fertilizer application in fruit plantations, which are long-term and re-grown in one place remains insufficiently studied. To solve this problem is possible only in long-term stationary studies, as the impact of different fertilizer systems on changes in soil properties and tree productivity for a long period of their use. The results of researches of long-term fertilizer influence on the main fertility indices of dark gray podzolic heavy loam soil and productivity of repeatedly grown apple trees of Idared varieties on seed and vegetative (M4) rootstocks and Calville snow on seedling rootstock are considered. During the 85-year period of growing the first and second generation of apple trees in the experimental garden, the organic fertilizer (40 t/ha of cattle manure), mineral fertilizer (N120P120K120) and their combination (20 t/ha of manure + N60P60K60) were applied in the old plantation every two years in autumn in plowing in rows at 18–20 cm, and in the new repetition: manure, phosphorus and potassium fertilizers as well, and nitrogen fertilizer in half doses annually in spring for cultivation or disk plowing to a depth of 12–15 cm. As a result of research it was found that organic fertilizer better than mineral fertilizers provided the formation of soil fertility (humus and mobile compounds and forms of nutrients, soil reaction) and yield capacity of experimental apple trees, which for all years of fruiting exceeded the total yield of Calville snow and Idared on seedling and vegetative rootstocks, respectively, by 34.8, 27.7 and 23.4 % compared with the yield of the control non-fertilized areas and 16.0, 15.8 and 13.2 % – on those fertilized with N120Р120К120. Similar parameters of soil fertility indicators are formed by the organo-mineral fertilizer system with systematic long-term application of half the norms of organic and mineral fertilizers of manure 20 t/ha together with N60P60K60. However, the mineral system (N120P120K120) significantly less increases the humus content and content of macronutrients available for plant nutrition and does not enrich the soil with trace elements, acidifies the reaction of the soil environment
