“…O maior valor de produtividade dos grãos de girassol com adubação organomineral em comparação com a produtividade obtida quando foi usada a fonte mineral, em uma dose de 50% da recomendação, é um indicativo dos benefícios Research, Society and Development, v. 10, n. 6, e4610615396, 2021 (CC BY 4. a médio e longo prazo da fração orgânica desta fonte, como resultante do aumento da fertilidade do solo, devido ao incremento de matéria orgânica e outros nutrientes, ou seja, melhoria dos atributos físico-químicos do solo (Higashikawa et al, 2017).…”

“…Para ambas as fontes, M e OM, o IC se adequou ao modelo de regressão polinomial quadrática, onde a dose de 194,44% para a fonte M promoveu o maior IC, igual a 0,29, sendo, 65,43% superior ao IC estimado na dose de 50%. Por conta do efeito residual, diversos estudos evidenciam a influência positiva dos adubos orgânicos no pH do solo, aumento da saturação por bases e da capacidade de troca catiônica, com isto pode-se verificar uma melhora na qualidade do solo, tornando-o capaz de fornecer condições adequadas para o crescimento, rendimento e índice de colheita das culturas(Kurtz, 2013;Higashikawa et al, 2017).…”

O acúmulo de matéria seca no girassol é extremamente importante para a produção de grãos, no qual, quando possui uma adubação inadequada a produção é prejudicada. Objetivou-se avaliar o acúmulo de biomassa e a produtividade de grãos do girassol adubado com formulados de NPK (mineral e organomineral). O experimento foi realizado em uma casa de vegetação, localizada em área experimental do IFGoiano – Campus Rio Verde – GO, no município de Rio Verde, Goiás. O delineamento experimental utilizado foi em blocos ao acaso, analisado em esquema fatorial 4×2 com três repetições. Os tratamentos consistiram em quatro doses do formulado 04-14-08 NPK: 50, 100, 150 e 200% da recomendação que correspondem, 90 kg ha-1 de N, 180 kg ha-1 de P e 40 kg ha-1 de K para a cultura do girassol e duas fontes mineral e organomineral. A aplicação dos formulados nas respectivas fontes e dosagens foi realizado na semeadura. Foram efetuadas as análises de acúmulo de matéria seca, massa de água e produtividade de grãos. A fonte NPK mineral proporciona maior massa fresca das folhas, massa seca do caule, massa de água e massa seca da parte aérea do girassol do que a fonte orgnomineral. As doses de 162 e 138% da recomendação de NPK, via fonte mineral e organomineral proporcionam a maior produtividade de grãos para a cultura do girassol, respectivamente.

“…Similar results were found by Júnior et al (2014), where an increase in K + content was verified in the soil, under the addition of organic material. The use of cattle manure in fertilization allows the improvement of soil quality, increases nutrient recycling and provides the reduction of mineral fertilizers (Higashikawa & Júnior, 2017), reducing the cost of production.…”

Nutrient management becomes essential in soils with low natural fertility, so the use of organic fertilizers can improve chemical properties of soil and reduce production costs. The objective of this study was to evaluate the effect of different fertilization sources on the chemical properties of soil under cassava cultivation. The experiment was conducted between 2017/2018 in the community of Boa Esperança, Santarém-PA using the cultivar Bem-te-vi, in the randomized block design with 4 treatments: T1 (without fertilization), T2 (fertilization NPK), T3 (organic fertilization with poultry manure), T4 (fertilization with cattle manure), with 5 replicates. The soil samples were analyzed for the contents K+, Ca²+, pH in H2O and KCl, Al³+ and soil organic carbon content (TOC). The data were submitted to analysis of variance and the means were compared by the Tukey test at 5% probability, using the software MINITAB© version 18. There were statistical differences between the treatments for all the chemical properties analyzed. The findings of the analysis were that fertilization with catle manure and NPK were the same and differed from the other treatments for the contents of K+, pH in H2O and KCl, for Ca²+ and TOC. The treatment without fertilization obtained the lowest values differing from the others, for Al³+. The source from NPK obtained the lowest content in the soil. The treatments with organic fertilizers had higher levels of the above nutrients in the soil. The chemical properties of the soil were altered from the different management systems for the cultivation of cassava.

“…The sowing for field formation in the experiments 1 and 2 (seed-to-bulb phase) was performed in March 2016, and the transplanting was done two months later. Seedbeds were plowed and fertilized according to the recommendations for growing onions (Higashikawa and Menezes Júnior, 2017). Two experiments were simultaneously conducted, one with advanced lines (109 genotypes), and the other with segregating lines (227 genotypes).…”

The cultivation of onion in Brazil has a relevant socioeconomic contribution. Despite the potential, there are few onion breeding programs for tropical conditions. One of the major obstacles is related to the complexity during the selection steps, since in onion, quantitative characters and low heritability predominate. For this reason, the purpose of this study was to assess the dynamics of expression between onion line traits based on phenotypic and genotypic correlations. Four sets of onion genotypes were assessed, comprising both advanced and segregating lines. The traits assessed were plant vigor, diameter of pseudostem, plant architecture, plant cycle, average bulb mass, bulb firmness and bulb postharvest. Phenotypic and genotypic correlations were calculated. Path analysis provided the estimate of the direct and indirect effects based on ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 19 (3): gmr18636
