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.
Shallots are one of the vegetable commodities that have important meaning for the community, both in terms of their high economic value and nutritional content. The productivity of shallots in West Nusa Tenggara is still low compared to the production potential of shallots. One of the causes of the low productivity of shallots is that the conventional shallot cultivation technique relies too much on chemicals and is planted in the dry season on dry land. One of the efforts to increase the productivity of shallots is by administering the biostimulant Trichoderma and the Growth Regulatory Substance Benzyl Amino Purine (GRS BAP). This study aims to determine the growth response and yield of shallots to the biostimulant Trichoderma and GRS BAP. The study used an experimental method which was carried out on land owned by farmers in Sembalun Bumbung Village, Sembalun District, East Lombok Regency. The study used a Randomized Block Design with a factorial experiment consisting of 2 factors. The first factor was Trichoderma biostimulant which consisted of four levels, namely: without biostimulant, Trichoderma harzianum Sapro-07 fungus biostimulant, T. koningii Endo-02 fungus biostimulant, and mixed fungi biostimulant T. harzianum Sapro-07 and T. koningii Endo-02. The second factor is: GRS BAP which consists of two levels, namely without GRS BAP and with GRS BAP. The results showed that shallot plants treated with a mixture of biostimulant fungi T. harzianum Sapro-07 and T. koningii Endo-02 either with or without GRS BAP could increase plant height, number of leaves, root length, and increase the number of tillers and shallot weight dry harvest. In other words, the mixed biostimulant of T. harzianum Sapro-07 and T. koningii Endo-02 fungi had the same role as GRS BAP in stimulating the growth and yield of shallots.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
