Effect of Giving Arbuscular Mycorrhizal Fungi (AMF) and Bioactivator Dosage of Trichoderma spp. on the Growth and Products of soybeans (Glycine max L. Merr.)

Abstract

Several factors become an obstacle to increasing soy production and achieving quality standards for soybean yields, including limited water, especially in rain-fed areas, that determine the success of soybean cultivation. The use of Trichoderma spp. Bioactivators and AMF can be a solution for adding organic material to soy cultivation. This study aims to investigate the effect of AMF and the bioactivator Trichoderma spp. on growth, yield in soybeans (Glycine max L. Merr,). The design used is a two-factor split-plot design. Because the main plot was AMF, which consisted of without and with AMF (15 g/plant). The subplot is the dosage of bioactivators (tablet and liquid form with legundi leaves fermented by Trichoderma spp.), Consisting of seven levels without bioactivators, 2.5 g tablets with bioactivators, 5.0 g tablets with bioactivators, and 7.5 bioactivators. g tablets, containing 2.5 ml liquid bioactivator, 5.0 ml liquid bioactivator, and 7.5 ml liquid bioactivator. The treatment was a combination of FMA factor and bioactivator dose, each of which was repeated three times so that there were 42 experimental units. The results showed that the administration of AMF at a dose of 15 g/plant showed better growth of the soybean plant and yielded a yield of 29.27% or 1.13 tons/ha. While the administration of Trichoderma spp bioactivator at a dose of 5.0 ml can increase the growth of soy plants and give higher yields of dry soybean seeds, namely 31.54% or 1.28 tons/ha.

Growth Response and Yield of Shallots to Trichoderma Biostimulants and Growth Regulators Substance Benzyl Amino Purine (GRS BAP)

“…The effect of Trichoderma-based biostimulant and nitrogen (N) fertilization rate on agronomic performance and functional quality can increase the weight of lettuce and rocket vegetables [41]. The use of tablet and liquid bio activators with the use of AMF can increase the induced resistance of soybean plants to wilt disease and increase soybean growth and yield [14]. The use of bio activators and biocompost fermented with Trichoderma spp.…”

“…Yusrinawati et al [13] said that the use of T. harzianum bioactivator in combination with Arbusclar Mycorrhizal Fungus (AMF) can stimulate the growth and yield of shallots. Yudhiarti et al [14] said that the use of bioactivator in tablet and liquid formulations in combination with AMF can increase soybean growth and yield. Pascual et al [15] said that biostimulants in the form of compost enriched with T. harzianum T-78 (Th T-78) as a growing medium showed higher growth and yield of melons than without biostimulants.…”

Effect of Biofertilization , Potassium Humate and Rates of Npk Fertilization on Growth, Yield and Economic Indicators of Soybean.

“…In addition, this is because the roots of plants infected with MF can more efficiently utilize phosphorus and nitrogen in the soil, thus promoting the growth and development of plants and increasing the biomass (Alori et al, 2017). MF application to soy-bean plants resulted in a much higher number of leaves than the control treatment, according to study by Yudhiarti et al, (2020). Mycorrhiza can help plants absorb more nutrients, particularly P, which is crucial for the process of photosynthesis.…”

The Effect of Trichoderma Biourine Application on Growth, Occurrence of Fusarium Wilt Disease and Yield of Several Shallot Varieties

“…Tablet and liquid bioactivator fermented with Trichoderma spp. can increase soybean plant-induced resistance to wilt disease and increase soybean growth and yield [30] and biocompost fermented with Trichoderma spp. can increase the weight of shallot bulbs [17].…”
