“…According to [ 22 ], banana plants infected with the fungus had a lower plant height, smaller pseudo-stem diameter, wilting, and yellowing of leaves, which also dropped. Din et al (2018) [ 23 ] also found that, when banana roots were infected with FOC, their pseudo-stem size, root size dispersion and plant height decreased. The total dry biomass indicated that the partitioning of resources were transformed in banana plants; however, the dry biomass output of the banana seedlings decreased as a result of the biotic stress caused by FOC infection, notably in the leaves and roots [ 24 , 25 , 26 ].…”

The amendment of soils with silicate (Si) compounds is essential to promote growth performance and control Fusarium wilt disease in bananas. Two successive greenhouse trials were conducted at the experimental farm of the University of Putra Malaysia. The treatments were arranged in split plots using a randomized complete block design (RCBD) with four replicates to investigate the effects of Si compounds and application frequency on controlling FOC. Si compounds were used at a constant concentration of 0.1%: T0 (control), T1 (13% SiO2:20% K2O), T2 (26.6% SiO2:13.4% K2O) and T3 (36.2% SiO2:17% Na2O). There were three application frequencies by day intervals (DI): 0DI (without any application), 7DI (12× within 12 weeks after transplanting (WAT)), 15DI (6× within 12 WAT) and 30DI (3× within 12 WAT). From these findings, we observed that the photosynthesis rate started to increase from 10.6 to 19.4 µmol CO2 m−2s−1, when the total chlorophyll content started to increase from 3.85 to 7.61 mgcm−2. The transpiration rate started to increase from a value of 1.94 to 4.31 mmol H2O m−2s−1, when the stomata conductance started to increase from 0.237 to 0.958 mmol m−2s−1. The proline content started to increase from 22.89 to 55.07 µmg−1, when the relative water content started to increase from 42.92 to 83.57%.

“…The quantification of proline content in the Berangan banana leaves was performed according to the method described by [ 23 ] and expressed as µmolg −1 of fresh weight. The plant tissues collected from the fresh banana leaves (approximately 0.5 g) were ground in liquid nitrogen and stored for further analysis.…”

A Field Evaluation of Sodium Silicate and Bacillus subtilis on the Growth and Yield of Bananas following Fusarium Wilt Disease Infection

et al. 2023

A field investigation was conducted in a Fusarium-infected area to evaluate the effectiveness of silicate compounds with antagonist bacteria on morpho-physiological growth performance in bananas. The roots of banana plants were treated by drenching the soil with four different treatments: control (without any treatment), CBZ (Carbendazim fungicide alone), SS + BS (integration sodium silicate with Bacillus subtilis), and CBZ + SS + BS (integration CBZ, SS, and BS). All treatments were arranged in a randomized complete block design with four replications. The results confirm that plant height, pseudo-stem diameter, and canopy diameter markedly increased from weeks 2 to 10 after transplantation. Amendment with these elements induced a higher total chlorophyll content, which contributed to the increased rate of leaf gas exchange and biochemical changes for controlling Fusarium wilt disease infection. From these findings, the CBZ + SS + BS application in the farm had significantly reduced disease incidence by 16.07% and disease severity by 14.28%. The same treatment achieved the greatest disease reduction by 63.05%. Therefore, the integration between CBZ + SS + BS had good significant effects in controlling Fusarium wilt disease and enhanced the morpho-physiological growth performance with an average yield production of about 24.72 kg per fruit bunch.

Slow growth rate of tissue-cultured banana seedling’s performance and high post-transplanting mortality rate are commonly due to low rate mineral content in the soil, climate change and soil-borne disease. This study aimed to evaluate the effects of potassium silicate (K2SiO3) on growth, physio-biochemical changes on Berangan banana seedlings grown under tropical climate conditions. The experiment was conducted under a rain shelter and all treatments were arranged in a randomized complete block (RCBD) design. The plants were soil drenched with K2SiO3 at constant 0.0901 M by 25 mL/plant after two weeks of transplanting with different frequencies application: 0-day interval (DI) served as control, 7 DI (12×), 15 DI (6×) and 30 DI (3×) throughout three months experimental period. Results showed that K2SiO3 (13% SiO2, 20% K2O) applied on healthy banana seedlings at 15 days interval significantly improved morphological growth trait (plant height, pseudo-stem diameter size, total leaf area, root length, and dry matter biomass) and physiological traits characters, but reduced proline and MDA content in plant tissues of banana. Hence, the results confirmed that each banana seedlings that received K2SiO3 at optimum frequency rate (15DI) had successfully enhanced the growth performance with better quality of Berangan banana seedlings at commercial-scale production.
