“…Formononetin application influenced the variables RDM, TDM and DQI in L. leucocephala seedlings positively ( Table 2). The use of formononetine, as a stimulant of mycorrhization in plant cultization, has shown it has the capacity to stimulate colonization by native species of mycorrhizal fungi and so increase productivity in a variety of crops, including beans (LAMBAIS et al, 2003), potatoes (DAVIES (1995), soya (CORDEIRO et al, 2015) and pallisade grass (Urochloa brizantha = Brachiaria brizantha) (SANTIAGO et al, 2017).…”

“…A aplicação da formononetina influenciou positivamente as varáveis MSR, MST e IQD das mudas de L. leucocephala (Tabela 2). O uso da formononetina, como estimulante de micorrização nas culturas, tem demonstrado capacidade de estimular a colonização com espécies nativas de fungos micorrízicos e, assim, aumentar a produtividade de diversas culturas, como feijão (LAMBAIS et al, 2003), batata (DAVIES et al, 2005) soja (CORDEIRO et al, 2015 e capim-marandu (SANTIAGO et al, 2017).…”

“…In addition to providing a substrate with a composition suitable for quality seedling production, plant species that benefit from the symbiosis with mycorrhizal fungi may also show greater increases in root and shoot dry mass if such associations are facilitated by the substrate (SILVA et al, 2017). In the seedling phase this can be of key importance in decreasing the time spent developing the nursery.…”

“…Além da adequada composição do substrato para a produção de mudas de qualidade, as plantas que se beneficiam da simbiose com fungos micorrízicos podem, também, apresentar maiores incrementos na massa seca de raízes e parte aérea (SILVA et al, 2017), o que pode ser fundamental em fase de muda para diminuir o tempo de permanência no viveiro. O uso de estimulantes para estabelecer a colonização de fungos micorrízicos em raízes tem grande potencial na agricultura (ANDRADE et al, 2018).…”

To obtain quality saplings it is necessary to consider the requirements the plants have for a balanced nutriente intake. These can be made available from organic waste which, in many cases, is simple to acquire and can be recycled easily. Consequently, the current study evaluated the potential of organic substrates and formononetin for the production of Leucaena leucocephala seedlings. Experiments were carried out in a greenhouse, using a fully randomized experimental design, in a factorial arrangement (5 x 2), with five soil proportions: organic compound (100: 0, 80:20, 60:40, 40:60, 20 : 80) and two doses (0 and 1.0 mg per seed) of the isoflavonoid formononetine (7-hydroxy-4’-methoxy-isoflavone, Myconate®). After 60 days of sowing, shoot height, stem diameter, shoot height ratio, shoot diameter, number of nodules, aerial dry mass (ADM), root dry mass (RDM), total dry matter and Dickson Quality Index (DQI) of the Leucaena leucocephala seedlings were evaluated. Formononetin positively influenced dry root and total dry mass production, and the Dickson Quality Index of Leucaena leucocephala seedlings. A substrate with 46% soil and 54% organic compound gave the highest seedling DQI, this thereforee being the recommended proportions for this specieds during the initial growth phase.

“…Regarding leaf contents of P and K, values of 5.79 and 28.90 g kg -1 were obtained for the doses of 1.20 and 1.32 cmol c Ca dm -3 , respectively. Phosphorous establishes a strong relationship with Ca in the soil because of the significant increase in P availability with liming (Santiago et al, 2017).…”

Lima bean stands out in the agricultural sector as a source of income for small and medium farmers, being an important protein source for the population. However, there few studies related to the adequate management of fertilization that subsidize the maximization of crop production. In this context, the objective of this research was to evaluate the effect of macronutrient doses on the yield components and nutritional status of lima bean. The treatments were chosed based on the statistical arrangement of the Baconian method. Six nutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) were applied in three different doses along with two additional treatments, one with reference doses and the other with no addition of nutrients, totaling 20 treatments that were arranged in a completely randomized design with four replications. The pod length, pod number per plant, pod weight, number of grains per pod, number of grains per plant, grain weight per plant and macronutrient leaf contents were evaluated. The addition of macronutrients leads to increases in yield components and nutritional status of lima bean s when cultivated in Entisol Quartzipsamment. The doses of macronutrients that promote higher productive yield and adequately supply the nutritional needs of lima beans are: 25 mg N dm-3; 157 mg P2O5 dm-3; 90 mg K2O dm-3; 1.27 cmolc Ca dm-3; 0.50 cmolc Mg dm-3 and 30 mg S dm-3.

The formononetin biostimulant may be an option for reducing P fertilization once it stimulates mycelial growth of arbuscular mycorrhizal fungi and increases plant ability to take up nutrients through the roots, especially phosphorus. The objective of this study was to evaluate the effect of formononetin associated with phosphorus fertilization in maize. Field experiments were conducted in a randomized block design with a 3 × 4 factorial arrangement (0, 50 or 70, and 140 kg ha -1 P 2 O 5 ; and formononetin application rates: 0, 25, 50, and 100 g ha -1 ), with four replications. Formononetin (100 g ha -1 ) increased the mycorrhizal colonization rate up to 30% in maize in the fi rst four weeks after emergence when no P fertilizer was applied, and to 17% when 50 or 70 kg ha -1 of P 2 O 5 were applied. The application of 50 and 100 g ha -1 of formononetin signifi cantly increased plant height, ear height, and grain yield (22% -76%) when no P fertilizer was applied. The use of formononetin in the fi eld stimulates mycorrhizal colonization, has a positive effect on maize yield, and reduces the need for P fertilizer application in maize.However, this effect was evident only at low P soil contents.
