Resumo: | The growing need to increase food production constitutes a serious scientific-technological challenge, requiring the expansion of cultivated sites also with the utilization of degraded areas, such as soils affected by salts. In order to achieve that, alternatives to mitigate such limitations have been pursued, such as the use of biofertilizers in the formation process of neem seedlings. In the pursuit for alternative and ecological control methods considered healthy and sustainable, the use of the neem tree (Azadirachta indica) associated with organic inputs in semiarid regions is highlighted, since this species possesses azadirachtin as the main bioactive compound, capable of acting against more than 418 plague species due to its insecticidal properties. An experiment was conducted in a screened plant nursery in the municipality of Areia – PB, in the period from January to July 2016, to evaluate the effects of the supplemental irrigation with saline waters on the absolute growth of neem seedlings in soil with biofertilizer. The substrate was a Dystrophic Red- Yellow Latosol. The experimental design was in randomized blocks, in a 5x2x3 factorial scheme, with four replications. The treatments were irrigated with five levels of water salinity (0.5; 1.5; 3.0; 4.5; 6.0 dS m-1), in the soil without and with common fermented bovine biofertilizer, and evaluated after three periods: 30, 60, and 90 days after the emergence of the plantlets, for the determination of the absolute growth in AP, DC, IAF, MSR, MSPA, and MST. The liquid fermented biofertilizer, after diluted, was applied a single time in a 1:3 proportion, two days before sowing, at the level of 10% the volume of the substrate. The treatments with fermented bovine biofertilizer provided better conditions for the growth and development of the neem through osmotic effect than in the soil without the input as a function of the time. |

Para isso, tem-se buscado alternativas para mitigar tais limitações, como o uso de biofertilizantes no processo de formação das mudas de nim. Na busca por métodos de controle alternativo e ecológico, considerados saudáveis e sustentáveis, destaca-se a utilização do nim, Azadirachta indica, associado aos insumos orgânicos em regiões semiáridas por possuir azadiractina como principal composto bioativo, capaz de atuar contra mais de 418 espécies de pragas por suas propriedades inseticidas. Um experimento foi conduzido em abrigo telado no município de Areia - PB, no período de janeiro a julho de 2016, a fim de avaliar os efeitos da irrigação suplementar com águas salinas sobre o crescimento absoluto das mudas de nim no solo com biofertilizante. Como substrato foi utilizado um Latossolo Vermelho Amarelo distrófico. O delineamento experimental foi em blocos casualizados com esquema fatorial 5x2x3, com quatro repetições. Os tratamentos foram irrigados com cinco níveis de salinidade de água (0,5; 1,5; 3,0; 4,5; 6,0 dS m-1), no solo sem e com biofertilizante bovino comum fermentado, avaliados após três períodos: 30, 60 e 90 dias após emergência das plântulas para determinação da taxa de crescimento absoluto em AP, DC, IAF, MSR, MSPA e MST. O biofertilizante liquido fermentado depois de diluído foi aplicado uma única vez na proporção de 1:3, dois dias antes da semeadura, ao nível de 10% do volume do substrato. Os tratamentos com biofertilizante bovino fermentado proporcionaram melhores condições ao crescimento e desenvolvimento do nim por efeito osmótico do que no solo sem o insumo em função tempo.UEL2019-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Científico - Em casa de vegetação.application/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3465710.5433/1679-0359.2019v40n6Supl3p3359Semina: Ciências Agrárias; Vol. 40 No. 6Supl3 (2019); 3359-3372Semina: Ciências Agrárias; v. 40 n. 6Supl3 (2019); 3359-33721679-03591676-546Xreponame:Semina.
