In general, fertilization recommendations for pepper are old and scarce. Because pepper is a semi-perennial crop with high yield potential and dependence on phosphorus (P), an extremely important element, as it participates in several metabolic processes, it is necessary to look for efficient alternatives for phosphatefertilization, due to its low availability and high adsorption capacity in most Brazilian soils. Slow-release fertilizers have been shown to be an excellent alternative to conventional mineral fertilization. Therefore, the objective of this study was to evaluate the effect of different sources of P on growth and yield of hot pepper (Capsicum frutescens L.). An experiment was carried out in a greenhouse in the JK campus of UFVJM, Diamantina -MG, Brazil, arranged in a completely randomized design with eleven treataments(absence of fertilization, mineral treatment, organic treatment and four slow-release phosphate sources: pelleted organomineral, granulated organomineral, MAP coated and triple formulated, at doses of 150 and 300 kg ha-1 of P2O5). Growth variables, fresh and dry matter accumulation and yield were evaluated 180 days after planting. The pelleted and granulated organomineral treatments at the dose of 300 kg ha-1 of P2O5,promoted the best results for the parameters dry mass of root, number of fruits per plant, fresh and dry mass of fruits and total yield. Such results can be explained by the better efficiency of P release and the better absorptionof this nutrient by the plant, making it an excellent option in relation to conventional sources commonly adopted.

“…The organominerals category grew by 80.5% in the specialty fertilizers market between 2019 and 2020 (ABISOLO, 2021). Several scientific results demonstrate the efficiency of organomineral fertilizers in the most varied cultures, such as corn (Aguiar, 2022;Fernandes et al, 2020;Franco et al, 2020;Teixeira et al, 2011), beet (Aguiar et al, 2021), pepper (Macedo et al, 2021), strawberry (Farnezi et al, 2020), and sugar cane (Teixeira et al, 2012;Teixeira, 2013;Borges et al, 2019;Estrada-Bonilla et al, 2021).…”

Commercial characteristics of coffee seedlings produced with different sources of phosphorus and plant growth-promoting bacteria

et al. 2023

Considered the economic engine of many countries, the coffee culture represents an important component of the agricultural chain in Brazil. The growing values of commercialization, planting areas, and crop productivity require the acquisition of quality seedlings, which must receive adequate nutritional support through efficient fertilizers. Slow and controlled-release fertilizers, such as organominerals, gain prominence when it comes to increasing efficiency in the use of phosphorus, as well as plant growth-promoting bacteria (PGPB) with phosphate solubilizing characteristics. This study aimed to evaluate the effect of different sources of mineral and organomineral fertilizers, inoculated and non-inoculated with PGPB on the quality parameters of coffee seedlings. In general, the P sources used in the experiment positively interfered with the development of coffee seedlings. This proves that there is a need for nutritional supplementation for the good development of the seedlings. Among the sources used, the organomineral in granulated form showed better performance in coffee seedlings' growth and physiological parameters, proving to be a viable alternative to commonly used fertilizers. The addition of PGPB showed a significant advantage for seedling quality variables.

“…Os FOM são constituídos por matéria orgânica (MO), rica em substâncias húmicas (PRADO et al, 2016), que auxiliam na melhor utilização dos nutrientes pelas plantas (BARCELOS et al, 2019), principalmente, devido à redução na disponibilidade de fósforo (P) pela competição nos sítios de adsorção (FINK et al, 2016).Assim, os fertilizantes organominerais fornecem os nutrientes de maneira gradual, diminuindo os custos e evitando perdas para o ambiente (FERNANDES et al, 2020). Além disso, a MO atua sobre a estruturação, fertilidade e biologia do solo, refletindo na fisiologia vegetal, pela alta capacidade de troca catiônica (CTC) e retenção de água nos microporos (KIEHL, 1999), fatores considerados importantes, especialmente em solos com constante revolvimento, perfil raso e fertilidade reduzida como os de terras baixas na Fronteira Oeste do RS.…”

A área semeada com soja em terras baixas vem aumentando nos últimos anos em sucessão ao arroz irrigado por inundação, sendo que os solos destas áreas geralmente apresentam baixa fertilidade natural, fator limitante para o desenvolvimento da cultura. Neste sentido, o presente estudo tem por objetivo avaliar a resposta da cultura da soja adubada com fertilizante organomineral (FOM) e mineral em um solo típico de terras baixas. O experimento foi conduzido em um Plintossolo Argilúvico distrófico, de ampla ocorrência em terras baixas na Fronteira Oeste do Rio Grande do Sul. O delineamento experimental foi de blocos ao acaso em esquema fatorial 2 x 5, com quatro repetições, sendo as fontes organomineral e mineral e, doses (0, 200, 400, 600 e 800 kg ha -1 ). As variáveis analisadas foram os índices biométricos (altura de plantas e altura de inserção da primeira vagem) e componentes de rendimento (número de vagens por planta, número grãos por vagens, peso de mil grãos e produtividade), sendo os resultados submetidos à análise variância e regressão ao nível de 5% de significância. A cultura da soja respondeu positivamente as
