| El uso de abonos orgánicos a través del agua residual de suinocultura (ARS) puede afectar positivamente los atributos químicos del suelo, debiendo ser monitoreado, debido a que un exceso puede constituir un alto contaminante ambiental. El objetivo de este trabajo fue evaluar las alteraciones de atributos químicos del suelo y tenores foliares de los cultivos de soja y maíz segunda zafra en función de aplicaciones de dosis de ARS. El experimento fue conducido en un Rhodic Kandiudox, bajo sistema de siembra directa, en el Centro de Investigación de la Cooperativa Agroindustrial Consolata. Fue utilizado un diseño experimental de bloques al azar con parcelas subdivididas, siendo colocadas en las parcelas principales dosis de 0, 35, 70,105 e 140 m3 ha-1 año-1de... |

| Fertilizantes organominerais podem incrementar o teor de nutrientes dos fertilizantes e também podem aumentar a eficiência dos fertilizantes minerais. Desta forma, o trabalho teve o objetivo de avaliar a disponibilidade de P do fertilizante organomineral Umostart em comparação com fosfato monoamônico em plantas de milho. Foi conduzido um experimento em casa de vegetação no município de Marechal Candido Rondon – PR, em delineamento de blocos ao acaso com quatro repetições e com arranjo fatorial 5x2x2. Foram avaliadas cinco doses de P (0, 75, 150, 225 e 300 mg dm-3), duas fontes (Umostart e MAP-Fosfato Monoamônico) e dois solos, argiloso (LVef) e arenoso (PVd). Aos 30 dias após semeadura foi avaliado a produção de matéria seca da parte aérea e raízes, assim... |

| Evaluating the potassium (K) availability to the plants can be performed by different methods. In general, multielement methods are employed and they are used for K due to increase operational of soil testing laboratory. The efficacy of ammonium acetate, Mehlich-1, Mehlich-3 and ion exchange resin soil K extractantsin determining the K availability for soybean [Glycine max L. (Merrill)], in different Parana’s soils, were investigated in this study. Twelve soil samples, collected from the upper layer 0–0.20 m, were cultivated with soybean for 42 days in greenhouse conditions. The average amount of available soil K extracted in test soils was found, displayed in decreasing order: ammonium acetate > Mehlich-3 > Mehlich-1 = ion exchange resin.... |

| O estudo das frações húmicas auxilia na elaboração de estratégias de manejo do solo, priorizando a adoção de sistemas que melhorem a qualidade do solo. Diante do exposto, objetivou-se com o presente trabalho verificar alterações nas frações químicas da matéria orgânica do solo (MOS) sob diferentes cultivos de inverno e fontes de fertilizantes. As amostras de solo foram coletadas nas camadas de 0,00-0,05; 0,05-0,10; 0,10-0,20 e 0,20-0,40 m, em 2015 e 2016. O delineamento experimental utilizado foi blocos casualizados em parcelas subdivididas, contendo quatro repetições. Na safra de verão, todas as parcelas foram cultivadas com soja. No período de inverno, as parcelas receberam as culturas de aveia preta, crotalária, milho, milho + braquiária e trigo. Nas... |

| The objective was to evaluate the effect of calcium silicate on the chlorophyll content and gas exchange of two tomato hybrids. The design used was in randomized blocks in a 2x5 factorial scheme, with four replications. The first factor was composed of two tomato hybrids: Ivety and Natália, and the second factor was composed of five doses of calcium silicate (0, 150, 300, 450, and 600 kg ha-1), applied to the substrate before planting the seedlings. Gas exchange: net CO2 assimilation rate (A), leaf transpiration rate (E), stomatal conductance (gs), internal CO2 concentration (Ci), water-use efficiency (WUE), intrinsic efficiency water use (iWUE), and instant carboxylation efficiency (ACi); SPAD index and the levels of chlorophylls a, b, and total were... |

| The increase in costs of selected and certified soybean seeds is evident in recent years. Knowing that farmers can use saved seeds, the aim of the study was to evaluate the physiological and sanitary quality of saved seeds produced in the first and the second crop in Western Paraná State, Brazil, compared to commercial seeds. The experiment was conducted at Seed Laboratory of the State University of West Paraná, with seeds of soybean cultivar Vmax RR (NK 7059RR), arranged in 5x3 factorial with four replications. For the first factor treatments refer to seed lots with different sources of production: two lots in the second crop of 2010 with and without seed treatment (ST), two lots of first crop of 2010/2011 with and without ST and one commercial lot of... |

| There is urgency in researches for recommendation doses, timing and methods of swine wastewater (SW) application, which is made up of organic waste and minerals, which can be absorbed by plants. The objective was to evaluate economic viability and the effect of swine wastewater associated with mineral fertilizer in succession soybean crop and second crop corn under no tillage system in Oxisol on West of Paraná State, Brazil. From September 2013 to August 2014, an experiment was conducted with five doses of swine wastewater (0, 35, 70, 135 and 140 m3 ha-1 yr-1), and two levels of mineral fertilizer (absence and presence). Treatments arranged in a completely randomized split-plot blocks with four replications, allocated to plots the factor doses of swine... |
