This work aims to investigate the efficiency of a novel organic mineral fertilizer produced with filter cake residue from sugarcane mills. The novel fertilizer was developed based on the mixing of minerals with an organic compost, conditioning, and pelletizing of mixture. The minerals consist of conventional soluble mineral nutrients and the organic phase consists of insoluble filter cake compost obtained from an assisted composting process. Efficiency of conventional and organic mineral fertilizers was measured in real field soybean crop through a randomized block design with four replications. Variables analyzed were productivity, NPK nutrient in leaves. The experiment was carried out in Tupaciguara/MG, Brazil. Experimental results showed higher soybean productivity and leaf nitrogen content in the organic mineral treatments than mineral ones in all dosages tested, with statistical relevance for 80% and 100% NPK dosages.

O mamoeiro é umas das plantas frutíferas mais comuns em quase todos os países da América Tropical. Um dos principais problemas na cadeia produtiva da cultura de mamão é obter bom manejo do material propagativo e garantir uniformidade e qualidade de estande, sendo para isso necessária a obtenção de mudas de qualidades fisiológicas e sanitárias adequadas.  A utilização de produtos alternativos vem demonstrando efeitos significativos no desenvolvimento radicular de várias plantas, o que beneficia a formação de um pomar de maneira rápida, homogênea, permitindo assim a antecipação da colheita e maior lucratividade ao produtor. O objetivo deste trabalho foi avaliar o efeito do organomineral em diferentes doses na produção de mudas da cultura do mamoeiro da cultivar Sunrise Solo Line 72/12, em condições de ambiente protegido. O experimento foi conduzido no viveiro de mudas do Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II. O delineamento experimental utilizado foi de blocos inteiramente casualizados, com seis tratamentos (0; 0,050; 0,100; 0,200; 0,300 e 0,400 kg tratamento de organomineral) e quatro repetições (6X4), utilizando 5 saquinhos por repetição, totalizando 120 saquinhos. Os dados biométricos analisados foram altura da planta (cm); comprimento da raiz (cm); diâmetro do caule (cm); massa úmida e seca da área foliar (g) e massa úmida e seca da raiz (g), aos 60 dias após plantio. Com base nos dados obtidos dos caracteres agronômicos analisados, conclui-se que o uso das doses 0,050; 0,100; 0,200 e 0,300 kg por tratamento de fertilizante organomineral promoveu a obtenção de mudas de mamoeiro com maior qualidade fisiológica que são imprescindíveis na formação de pomares comerciais.   REVIEW OF DIFFERENT DOSES OF ORGANIC MINERAL FERTILIZERS FOR PAPAYA SEEDLING DEVELOPMENT   ABSTRACT The papaya tree is one of the most common fruit trees in almost all Tropical American countries. One of the main issues in the papaya cultivation production chain is obtaining good management of propagative material and provide uniformity and quality for sales quality assurance, being to this end necessary to obtain physiological and sanitary appropriate seedling. The use of alternative products has demonstrated significant effects on the root development of several plants, benefiting a fast, homogeneous formation of an orchard, resulting in the anticipation of the harvest and higher profitability for the farmers. This paper aims at reviewing the organic mineral in different doses to produce papaya tree seedling from cultivar Sunrise Solo Line 72/12, in environment-protected conditions. The experiment was carried out at the Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II greenhouse. The trial design chosen was the completely randomized blocks, with 6 treatments (0; 0,050; 0,100; 0,200; 0,300, and 0,400 kg organic mineral treatment), and four repetitions (6X4), using 5 small bags per repetition, total 120 small bags. Biometric data analyzed was the plant height (cm); root length (cm); stem diameter (cm); wet and dry mass of the leaf area (g), and wet and dry mass of the root area (g), 60 days after planting. Based on the data obtained from agronomic characters analyzed, it was concluded that the use of 0,050; 0,100; 0,200, and 0,300 kg doses per treatment with organic mineral fertilizer provided papaya tree seedling with higher physiological quality which are vital for the commercial formation of orchards.   Keywords: Carica papaya L.

Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.

The efficiency of different types and doses of fertilizers and pre-sowing bacterization of pea seeds (Starter variety) on the formation and functioning of symbiotic nitrogen fixation system, crop productivity and protein content in grain was studied in long-term field experiment on the typical black soil for five years. It was shown that fertilizer doses not exceeding N60P60K60 were the most appropriate to use in the cultivation technology of pea. The use of manure, compost and organic-mineral fertilizer in crop rotation had positively affected the productivity of peas. Pre-sowing seed bacterization was proved to be an important agricultural practice as its application increases crop productivity and improves product quality.

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.

The results of researches of influence of the protracted application of the different systems of basic till of soil and fertilizer are presented on basic conformities to law and parameters of changes of the structural state that took place in an arable layer. It is educed that on a background a organic-mineral fertilizer for 20 years place improvement of structuralness of arable layer on 4,5-6,0 % by the greatest index for the moldboard systems. On a background a mineral fertilizer for this period the decline of amount of structuralness aggregates is marked from 0,1 % and chisel systems to 0,6 % and moldboard. In middle for 20 replacement of ploughing nonmoldboard tills on a background a organic-mineral fertilizer resulted in the decline of structuralness of arable layer on 2,0–8,0 %. On a background a mineral fertilizer a tendency was kept, though with some more subzero values, and to the organic-mineral background declines folded 0,1–3,7 %. Amount agronomical valuable aggregates in soil depended on the amount of debrises, evenness of their placing on an arable layer and from intensity of loosening. From time of sowing to the harvest the structuralness of soil got better with the greatest positive effect in sowing of mustard white, some more subzero, - to soy and most subzero - wheat winter-annual and at permanent advantage of background of organic-mineral fertilizer above mineral.

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.
