“…These authors found the same variation in pseudostem height and pseudostem diameter between the first and second production cycles, with average pseudostem height values of 3.5-4.5 m and pseudostem diameter of 0.25-0.30 m, respectively. The yields were relatively higher or similar to those reported by Roque et al (2014) In relation to the time between transplanting and bunch harvest, a tendency to a shorter time may be observed in the second production cycle, as the humic substances dose is decreased to the minimum point of the quadratic model curve (Figure 1).…”

Fertigation with humic substances products has been adopted in commercial banana tree plantations. However, there are few studies on the procedure to confirm its technical feasibility. This study aimed at assessing the effects of fertigation with humic substances on the chemical attributes of a Dystric Densic Xantic Ferralsol cultivated with the 'BRS Princesa' banana tree cultivar and on the agronomic performance of the orchard. The experiment was conducted using a randomized blocks design, with six treatments and four replications. Treatments consisted of a monthly application of humic substances doses based on the commercially recommended reference dose for the banana plantation (12.09 kg ha-1 cycle-1). The doses used were equivalent to percentages of the reference dose (100 %, 150 %, 200 %, 250 % and 300 %), in addition to the control. No significant effects of the fertigation with humic substances that could justify the use of the product at the doses assessed were observed on the soil chemical attributes, banana growth and yield.

“…The absolute means of PH, as well as PD, NL, and LAF (Table 3), were close to those reported by Roque et al (2014), who agronomically evaluated an irrigated cultivation of 'BRS Princesa' banana in the same region with the use of solid fertilization and without the use of humic substances.…”

“…The absolute means of HY observed in this study, for the production variables, are higher than those reported by Roque et al (2014). According to the F test of the analysis of variance, the absolute means of HY, LCF, and DCF were statistically superior to the absolute means of the treatments without PE application (Table 5).…”

RESUMO Submitted on February 29th, 2016 The use of humic substances and plant extract has been increasing mainly in organic crop systems without scientificbased recommendations. Research is necessary to evaluate the feasibility and the recommendations of these substances. The objective of this work was to evaluate the effect of humic substances (humic and fulvic acids) applied by fertigation with and without saponin-based plant extracts on growth and yield of 'BRS Princesa' banana. The experiment was carried out using the banana cultivar 'BRS Princesa', at a spacing of 2.0 × 2. ) applied with and without a saponin-based plant extract in a randomized block design in split-plot scheme. The following growth variables were evaluated: number of leaves, pseudostem height, pseudostem diameter, and length and width of the third leaf. The number of fruits/hand and hands/bunch, hand and bunch yield, and length and fruit diameter of the second central hand were evaluated during harvest. The doses of humic substances influenced only pseudostem height. Hand yield, as well as fruit length and diameter of 'BRS Princesa' banana were higher in plants fertigated with humic substance and plant extract in comparison with plants fertigated with only humic substance. Key words: Fertirrigação da bananeira 'BRS Princesa' com substâncias húmicas e extratos vegetais a base de saponinasO objetivo desse trabalho foi avaliar o efeito de substâncias húmicas (ácido húmico e fúlvico) aplicadas via fertirrigação com e sem extratos vegetais a base de saponinas nas variáveis de crescimento e produção da bananeira BRS Princesa (Musa sp.). O pomar foi instalado em espaçamento de 2,0 m x 2,5 m, em Latossolo Amarelo Distrocoeso, sob regime de fertirrigação por gotejamento, no Recôncavo da Bahia, Brasil. Os tratamentos consistiram em cinco doses de substância húmicas (0,0; 21,14; 31,71; 42,28 e 63,42 L ha -1 ciclo -1 ) com e sem aplicação de extratos vegetais, a base de saponinas. O delineamento experimental adotado foi o de blocos casualizados, em esquema de parcelas subdivididas no espaço com cinco repetições. Foram efetuadas análises biométricas na ocasião da floração e da colheita, sendo avaliados o crescimento e a produção acumulada, respectivamente. Mediante análise estatística foi verificado que, quando as substâncias húmicas foram associadas aos extratos vegetais, ocorreram influências significativas sobre a produtividade de pencas, comprimento e diâmetro de frutos e quando as substâncias húmicas foram aplicadas de forma isolada ocorreram efeitos significativos, apenas, sobre a altura de plantas.Palavras-chave: Extratos de plantas; irrigação por gotejamento; matéria orgânica; Musa sp.

“…Despite the wide range of varieties existing in Brazil, only a few cultivars have agronomic traits and fruit quality considered suitable for commercial exploitation (Roque et al 2014). In the Brazilian market, the main commercial cultivars are from the subgroups Cavendish (Nanica, Nanicão and Grand 1.…”

Despite the diversity of banana varieties in Brazil, only a few cultivars have the proper agronomic traits and fruit quality for commercial exploitation. This study aimed at evaluating the physicochemical traits and sensorial acceptance of banana genotypes, in order to identify those with potential for commercial growing. Six improved banana genotypes were assessed (BRS Maravilha, PC 0101, FHIA 18, TM 2803, YB 4203 and BRS Caipira), as well as three commercial cultivars (Grand Naine, Pacovan and Prata Anã). Analyses of peel and pulp color, peel thickness, pulp yield, moisture, pH, soluble solids, titratable acidity, total carotenoids and sensorial acceptance were performed. The BRS Maravilha, FHIA 18, YB 4203 and BRS Caipira genotypes presented physicochemical traits similar to the Grand Naine, Pacovan and Prata Anã commercial cultivars. The BRS Maravilha and TM 2803 genotypes had sensorial acceptance similar to the Prata Anã and Grand Naine cultivars, and are therefore promising for commercial growing, with the advantage of being resistant to the black Sigatoka and Panama disease.
