“…For the aerobic bovine biofertiliser (B1), the increasing linear model gave the best fit (Figure 2). These results corroborate those of Viana et al (2013), demonstrating that the biofertiliser application can strengthen the root system of the plants and promote the absorption of water and nutrients. Lima, Bellicanta and Moraes (2006) also obtained similar results for the biomass accumulation in the root system of micropropagated plants of the banana "Nanicão" fertilised with liquid organic fertiliser.…”

“…Similarly, Moreira and Fageria (2009), analysing the effect of organic fertilisation using biofertiliser with aerobic fermentation in leaves of the banana "Pacovan", recorded values lower than those of this study (18.09 g leaf N kg -1 ). However, Viana et al (2013), analysing the effect of organic fertilisation using bovine and mixed biofertiliser with aerobic fermentation on the leaves of melon plants, recorded values greater than those in this study (35.00 g leaf N kg -1 ). In addition, Cavalcante et al (2010), working under field conditions, found an increase in the N concentrations in okra plants fertilised with goat, cattle, and chicken manure as an organic source.…”

-Banana farming is an activity of great economic and social importance, and is carried out in most tropical countries. The aim of this work was to evaluate the biomass accumulation and levels of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) in micropropagated plants of the banana "Prata Catarina" during the acclimatization phase, under different types and doses of biofertilisers. The experimental design included randomised blocks in a 2 × 5 + (2) factorial scheme, with two types of liquid biofertilisers (bovine biofertiliser with anaerobic and aerobic fermentation) and five biofertiliser doses (0.25, 0.50, 0.75, 1.00, and 1.25 L plant -1 week -1 ), as well as two additional treatments (control and recommended mineral fertilisation). The following variables were analysed: dry weight of the leaves and roots, and mineral element content (N, P, K, Ca, and Mg) in different parts of the plant (leaf and root). During 90 days of acclimatization, the nutritional contribution of bovine biofertiliser with anaerobic fermentation was greater in comparison with the biofertiliser with aerobic fermentation and the control, but lower in comparison with mineral fertilisation. The 1000-mL dose of the biofertiliser with anaerobic fermentation promoted greater dry weight accumulation in the leaves and roots of the banana "Prata Catarina". The biofertiliser with anaerobic fermentation promoted higher levels of N, K, and Ca in the leaves, whereas the biofertiliser with aerobic fermentation promoted higher levels of P in the leaves and roots.Keywords: Musa sp..

ACÚMULO DE BIOMASSA E NUTRIÇÃO DE MUDAS MICROPROPAGADAS DE BANANEIRA PRATA CATARINA ADUBADAS COM BIOFERTILIZANTESRESUMO -A bananicultura destaca-se como uma atividade de grande importância econômica e social, sendo explorada na maioria dos países tropicais. O presente trabalho propôs avaliar o acúmulo de biomassa e os teores de nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca) e magnésio (Mg) em mudas micropropagadas de bananeira cv. Prata Catarina, durante a fase de aclimatização sob diferentes tipos doses e de biofertilizantes. O delineamento experimental foi em blocos casualizados em arranjo fatorial 2 × 5 + (2), referentes a dois tipos de biofertilizantes líquidos (bovino de fermentação anaeróbia e aeróbia) e cinco doses de biofertilizantes (0,25; 0,50; 0,75; 1,00 e 1,25 L planta -1 semana -1 ), com dois tratamentos adicionais (controle e adubação mineral recomendada). Foram analisadas as seguintes variáveis: massa seca das folhas, das raízes e teores de elementos minerais (N, P, K, Ca e Mg) nas diferentes partes da planta (folha e raiz). O biofertilizante bovino com fermentação anaeróbia apresenta maior aporte nutricional em relação biofertilizante de fermentação aeróbio e ao controle, porém menor em relação à adubação mineral para as mudas durante os 90 dias de aclimatização. A dose de 1000 mL do biofertilizante com fermentação anaeróbia promove maior acúmulo de massa seca nas folhas e raízes da ...

“…Esses resultados positivos ocorrem em razão do efeito do biofertilizante sobre a fisiologia das plantas, elevando as taxas de fotossíntese, transpiração e a condutância estomática, bem como na nutrição mineral das plantas (ERTHAL et al, 2010;SILVA et al, 2011;VIANA et al, 2013). …”

“…Esses fatores têm encorajado pesquisadores e produtores rurais a empregarem biofertilizantes preparados a partir da digestão aeróbica ou anaeróbica de materiais orgânicos, haja vista que são recomendados como forma de manter o equilíbrio nutricional de plantas (FERNANDES et al, 2000). Na literatura, são encontrados relatos sobre o efeito de biofertilizantes em diversas hortaliças e os estudos, em geral, detectaram aumento significativo no rendimento das culturas, a exemplo de estudos desenvolvidos com pimentão (ARAÚJO et al, 2007), maracujá (DINIZ et al, 2011), tomate (GOMES JÚNIOR et al, 2011), abóbora (SANTOS et al, 2012 e meloeiro (VIANA et al, 2013;SANTOS et al, 2014).…”

Resumo: Os frutos de maxixeiro são de grande apreciação na culinária brasileira, principalmente nas regiões Norte e Nordeste do Brasil. No entanto, é considerada uma cultura secundária e seu cultivo é realizado sem adoção de manejo tecnificado. Devido o seu cultivo ser realizado, principalmente, por pequenos produtores, as pesquisas empregando insumos produzidos na própria propriedade, como o biofertilizante, na adubação do maxixe são relevantes. Nesse sentido, objetivou-se com este trabalho avaliar o efeito de doses de biofertilizante na produtividade de duas cultivares de maxixe. Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial 2 x 4, com quatro repetições. Os fatores consistiram de duas cultivares (Do Norte e Liso Gibão) e quatro doses de biofertilizante (0; 8; 16 e 24 m 3 ha -1 ), aplicadas via fertirrigação. O experimento foi conduzido durante 100 dias, sendo realizadas seis colheitas, nas quais se avaliou as seguintes variáveis: número de frutos, massa de frutos, produção e produtividade. Todas as variáveis foram afetadas pela interação entre os fatores estudados. As cultivares estudadas não diferiram quanto à produção, no entanto, a cv. Do Norte apresentou maior número de frutos, enquanto a cv. Liso Gibão apresentou frutos mais pesados. A partir dos resultados obtidos, recomenda-se a dose de 14 m 3 ha -1 para a cultivar Liso Gibão. Para a cultivar Do Norte, recomenda-se mais estudos com doses mais elevadas de biofertilizante. Palavras-chave:Cucumis anguria L. Fertilizante orgânico. Insumo orgânico. Abstract:The fruit of the West Indian gherkin is greatly appreciated in Brazilian cuisine, especially in the north and northeast of Brazil. However, it is still considered a secondary crop, and is cultivated using non-technical management. As it is a crop produced mainly by small farmers, any research should be directed towards its cultivation using inputs produced on the farm itself, such as bio-fertilisers. The aim of this study was to evaluate the effect on the yield of two West Indian gherkin cultivars, of different doses of bio-fertiliser consisting of cattle manure and commercial products containing bacteria and enzymes that degrade organic molecules. A completely randomised design was used in a 2 x 4 factorial scheme with four replications. The factors included two cultivars (Do Norte and Liso Gibão) and four doses of bio-fertiliser (0, 8, 16 and 24 m 3 ha -1 ) applied through fertigation. The experiment lasted for 100 days, with six collections being made, for which the following variables were evaluated: number of fruits, fruit weight, production and yield. All the variables were affected by the interaction between the factors under study. The cultivars did not differ as to yield, however the De North cultivar gave the highest number of fruits, while the Liso Gibão cultivar produced fruit of a greater weight. From the results obtained, a dose of 14 m 3 ha -1 is recommended for the Liso Gibão cultivar. For the De Norte cultivar, further studies with higher doses of bio-fertilise...

Bovine manure biofertilizers can exert physical, chemical, and biological effects on the soil and the phytoprotective, physiological, and productive actions in horticultural crops. The literature review was performed to compile information on the production, uses, and effects of bovine manure biofertilizers on soil properties and plants. Biofertilizers are produced by organic components, minerals, and inoculants. Among the organic sources, the bovine manure is the most used. The fermentation of the bovine manure in water constitutes the Vairo biofertilizer, the most employed in Brazilian horticulture. With the chemical enrichment of this preparation came the Supermagro, Agrobio, and Agrobom biofertilizers. In the soil, it can act in the improvement of soil fertility, physical properties, and in the diversity and abundance of the biota. Also, it can act in control of pests and diseases, leaf composition concerning macro and micronutrients, and in the production and post-harvest quality of horticultural crops. Therefore, this review describes the preparation, chemical composition, and utilization of bovine manure biofertilizers in both soil and plants, offering perspectives of research on the formulations, application, and effects of these inputs on horticultural species.
