Utilization of biochar and mycorrhiza to increase the absorption of elemental nutrients of cayenne chili plant (Capsicum fruntescnes L.)

Abstract

This study aimed to obtain the composition of biochar as a soil enhancer and mycorrhizal dose, which affected the nutrient uptake of cayenne plants. This experimental research was based on a separate plot design (RPT) with a basic randomized block design (RCBD). The main plot experiment was vesicular-arbuscular mycorrhiza or VAM (m) with three levels: mycorrhiza 10 g/plant (m1), mycorrhiza 15 g/plant (m2), and mycorrhiza 20 g/plant (m3). The subplot is biochar composition as soil enhancer (b) with three types: biochar husk 50%+25% soil+25% sand (b1), 50% sand+25% soil+25% biochar wood (b2), and wood charcoal biochar 50%+soil 25%+biochar charcoal husk 25% (b3). Each level of the VAM doses factor is combined with biochar. These nine treatment combinations and the levels were repeated thrice, accounting for 27 experimental units. The results showed that the parameters of phosphorus uptake, potassium uptake, and fresh root weight had a positive and significant relationship to the percentage of mycorrhizal infections. The combination treatment of mycorrhiza 20 g/plant and the composition of 50% husk biochar+25% soil+25% sand, 15 g mycorrhizal dose treatment with 50% wood biochar+25% soil+25% biochar rice husk and 20 g/plant are the best treatment as a planting medium.

The Effect of Funneliformis mosseae and Biochar Against Verticillium dahliae in Pepper Plants under Salt Stress

“…Arbuscular mycorrhizal (AM) fungi and Bc can play a vital role in plant growth, even under stress conditions (Khrieba et al, 2019; Lala et 2021; Giono et al, 2021;Boyno et al, 2022). This is believed to be related to the nutrient uptake of Bc and the creation of a safe habitat (Giono et al, 2021). However, the mechanisms of the combination of AM fungi and Bc are not fully understood (Warnock et al, 2007).…”

Application of Biocom-Phosphate Solubilizing Fungi and Coal Fly-Ash to Increase P-Availability of Peat Soil in Kalimantan

“…The total population of A. oryzae-Tb7 in the A. oryzae-Tb7 treatment decreased without biocom (P2= CFA+ PSF A. oryzae-Tb7), while the total population of A. oryzae-Tb7 increased in the A. oryzae-Tb7 treatment using a biocom (P4= CFA+ PSF A. oryzae-Tb7). The application of biochar and Mycorrhizal arbuscular can significantly increase the population of this fungus compared to without biochar (Bibiana et al 2021).…”

Effect of AMF propagule dosage forms on the growth and production of Amaranthus tricolor L.

“…One type of biofertilizer that can be used is mycorrhizal [9,10]. The use of mycorrhizae as biological fertilizer can be used as an alternative to avoid soil damage due to the use of inorganic fertilizers [11,12] and increase the efficiency of nutrient absorption [13,14].…”

“…Mycorrhizae are organisms from a group of fungi that form a symbiotic relationship of mutualism between fungi and plant roots [15,16]. Mycorrhizae have great potential as biological fertilizers because mycorrhizae are microorganisms that have a very important role for plants, namely facilitating the absorption of nutrients in the soil to increase plant growth [13,14], as a biological barrier against root pathogen infection [17,18], increasing water availability for plants [19], and increasing production growth hormones such as auxins, cytokinins, and gibberellins for their host plants [20,21]. In addition, mycorrhizae are also able to adapt to extreme environments, especially in marginal soils such as dry areas, low pH, acid soils, and soil contaminated with heavy metals [22,23].…”
