“…It is still necessary to research formulations that are accessible to farmers, meet plant demands for nutrients, and have a reliable manufacturing process (Magrini et al 2011;Maas et al 2020). Recent studies have focused on the quality and effects of fermented compost with manure (Quiroz and Flores 2019; Abo-Sido et al 2021) but less on plant-based compost (Pereira et al 2022).…”

Fermented composts obtained from a mixture of raw materials and a microbial inoculant, known as "bokashi," are alternatives used by many farmers around the world. We evaluated the chemical composition, fermentation pathways, N availability, and agronomic e ciency of fermented compost obtained from different plant-based raw materials. The standard compost formulation composition was 60% wheat bran and 40% castor bean bran. From this formulation, wheat bran was gradually replaced by coffee husk, brewery residue, and elephant grass bran, and leguminous bran replaced castor bean bran. Incubation tests evaluated nutrient content (C, N, P, K, Ca, Mg), pH, electrical conductivity, and fermentation pathways (by the organic acids lactic, acetic, propanoic, butyric, and ethanol). A bioassay in greenhouse conditions accessed N availability. Additionally, a eld experiment evaluated the agronomic e ciency of 5 formulations and 4 doses (0 to 400 kg N ha − ¹) in successive vegetable production. The formulations with a balanced C/N ratio showed the potential to combine desirable fermentative and nutritional characteristics with good N availability and plant growth. Some formulations drastically changed the compost characteristics, especially the full replacement of wheat bran for coffee husk and elephant grass, which presented undesirable fermentation pathways. Leguminous bran maintained the fermentative quality and increased the soil's biological activity but decreased the nutrient content, N availability, and vegetable productivity. The brewery residue showed the most prominent fermentation quality, nutrient content, and N availability. The addition of 30% coffee husk resulted in agronomic performance and nutrient accumulation similar to the standard compost.

“…High quality soils can favor plant development, even under adverse conditions. In this sense, the application of organic compounds, such as bokashi, can contribute to physical and biological aspects, in addition to providing nutrients (Lopes Pereira et al, 2022), resulting in an increase in crop yield (Saath et al, 2022).…”

The analysis of non-destructive variables in plants, such as the SPAD index, shows a growing trend of adoption in the field. However, it is necessary to determine comparative reference standards, aiming to assist in the interpretation of results obtained in the field and in making decisions about the management to be adopted. The study aimed to propose levels of interpretation of the SPAD index in oregano leaves based on the yield of the crop. The experiment was conducted in protected environment, randomized blocks design was adopted with four replications in 6 x 4 factorial scheme: six levels of water replacement (60, 70, 80, 90, 100, and 110% of the crop evapotranspiration-ETc) and four doses of bokashi (0, 100, 200, and 300 g m-2). For analysis, the data were subjected to variance analysis, multivariate analysis, regression and correlation. Productive management (water replacement and bokashi dose) influences the SPAD index response. Through mathematical analysis of the relationship between SPAD index and relative yield, the sufficiency ranges based on the SPAD index were determined in very low (<37) low (37-44), medium (44-46) and high (>46). The proposed classification of the sufficiency range for the SPAD index allows advances in the productive management of the oregano crop.
