“…Cavalcante et al (2010) also found a high PDM in the presence of the biofertilizer in relation to 0.5 dS/m³ water for guava seedlings. According to Sousa et al (2013), the biofertilizer provides an increase in photosynthetic rate and chlorophyll. This results in a greater assimilation and fixation of CO 2 , producing mass of total plant dry matter (PDM), which may have occurred in this study.…”

This study aims to evaluate the production of biomass of different cattle manure, and biofertilizer concentrations. The experiment was conducted between April and June 2014 in a greenhouse at the seedling production nursery of the State University of Paraíba (UEPB), Catolé do Rocha, Paraíba (PB) state. The experiment was completely randomized in a 5 x 2 factorial design corresponding to five levels of cattle manure (0, 20, 40, 60 and 80% of the substrate volume) in the absence, and the presence of a biofertilizer. The propagation material was giant yellow passion fruits with 95 to 100% of purity purchased in the local market. After 60 days, the following variables were evaluated: root dry matter (RDM), plant dry matter (PDM), root biomass (RB), shoot biomass (SB), plant biomass (PB), biomass percentage (BP), effective leaf area (ELA) and leaf area ratio (LAR). The interaction between cattle manure and fertilizer concentrations was significant for root dry matter, mass of total plant dry matter, root biomass, shoot biomass and total plant biomass. In turn, cattle manure affected significantly biomass percentage, effective leaf area and leaf area ratio. Cattle manure and biofertilizer make the production of yellow passion fruit seedlings feasible.

RESUMOObjetivou-se avaliar os efeitos do estresse salino em sistema semi-hidropônico na biomassa e nos teores de N, P, K, Ca e Mg em plantas de pimentão sob fertilização orgânica e mineral. A pesquisa foi conduzida em sistema semi-hidroponico em Limoeiro do Norte, CE. O delineamento experimental foi o de blocos casualizados em esquema fatorial 5 x 4, referentes as diferentes concentrações de água salina (0,5; 1,5; 3,0; 5,0; e 7,5 dS m -1 ) e 4 doses de aplicações de fertilizantes na solução nutritiva (D1 = 50% da dose recomendada; D2 = 100% da dose recomendada e D3 = 150% da dose recomendada na forma orgânica e D4 = 100% da dose recomendada na forma mineral, com 4 repetições. A irrigação com água salina até 3,0 dS m -1 promove maior massa seca da parte aérea, raiz e total da cultura do pimentão quando adubada com 100% da dose recomendada de biofertilizante. A salinidade da água de irrigação afeta o teor de N com 100% da dose recomendada de biofertilizante e na adubação mineral, o teor de P com 50, 100 e 150% da dose recomendada de biofertilizante e a partir da CEa 3,76 com adubação mineral e o teor de Ca e K em todas as adubações. O cultivo do pimentão adubado com fonte orgânica ou mineral em sistema semi-hidropônico é uma alternativa viável para a utilização da água de rejeito da dessalinização evitando a contaminação do lençol freático.

“…The bovine biofertilizer has a positive action, acting in the improvement of the soil quality in terms of aeration, besides the supplying of nutrients and organic matter to the plants. In addition, the WATER SALINITY AND BOVINE BIOFERTILIZER IN THE PRODUCTION OF EGGPLANT SEEDLINGS biofertilizer has many beneficial substances, among them humic substances, which promote the reduction of the osmotic potential of the soil solution, stimulating the absorption of water and nutrients by the plants in saline environments (SOUSA et al, 2013a).…”

The use of saline water in agriculture is an alternative for those producers that do not have water of good quality for irrigation, however, some crops do not tolerate saline stress and as a strategy to mitigate the saline stress effects it has been recommended the use of organic inputs. Based on that, the aim of this study was to evaluate the effect of different electrical conductivities of the irrigation water associated to the application of bovine biofertilizer in the eggplant (Solanum melongena L.) crop. The experiment was carried out in a greenhouse located at the Universidade Estadual da Paraíba, in the municipality of Catolé do Rocha-PB, Brazil. It was used a completely randomized experimental design, with a 4 x 2 factorial scheme, with 6 replicates. The treatments consisted of the combination of the electrical conductivity of the irrigation water (ECw): 0.8; 2.4; 4 e 5.6 dS m -1 and the application of bovine biofertilizer (presence and absence). Based on the results of this research, it was possible to conclude that irrigation with saline water from 0.8 dS m -1 affects negatively the growth and the dry matter production of eggplants. The application of bovine biofertilizer provides positive results in eggplant plants, attenuating the negative effects of saline stress. insumos orgânicos. Neste sentido, objetivou-se avaliar o efeito de diferentes condutividades elétricas da água de irrigação associado à aplicação de biofertilizante bovino na cultura da berinjela (Solanum melongena L.). O experimento foi conduzido em casa de vegetação localizada na Universidade Estadual da Paraíba no município de Catolé do Rocha-PB, Brasil. Adotou-se o delineamento experimental inteiramente casualizado, com esquema fatorial 4 x 2, com 6 repetições. Os tratamentos constaram da combinação da condutividade elétrica da água de irrigação (CEa): 0,8; 2,4; 4 e 5,6 dS m -1 e a aplicação de biofertilizante bovino (ausência e presença). Com base nos resultados desta pesquisa foi possível concluir que a irrigação com águas salinas a partir de 0,8 dS m -1 afeta negativamente o crescimento e a produção de matéria seca de berinjela. A aplicação de biofertilizante bovino proporciona resultados positivos nas plantas de berinjela, atenuando os efeitos deletérios do estresse salino.
