“…These results corroborate those of Cunha et al (2011), who observed a positive correlation between TOC and Cmic. High levels of Cmic reflect the presence of a high amount of active organic matter in the soil, which can maintain a high mineralization rate of plant residues (Stone et al, 2013). …”

Phosphorus fertilization and irrigation management are essential practices to increase coffee yields, though information is scarce about the effect of these practices on organic matter fractions of soils of the ‘Cerrado’ (savanna-like vegetation). The purpose of this study was to evaluate organic matter fractions of a clayey Oxisol under coffee with split applications of phosphorus (P) and water regimes. The experimental design was a randomized block with 3 x 2 factorial arrangement with three split applications of P (P1: 300 kg ha-1 P2O5 applied annually of which 2/3 applied in September and 1/3 in December; P2: 600 kg ha-1 P2O5 applied at planting and every two years, and P3: 1800 kg ha-1 of P2O5 applied only at planting, corresponding to a 6-year requirement), two water regimes (with and without irrigation) and three replications. Soil from the 0-5 and 5-10 cm layers was sampled. The total organic carbon (TOC), labile carbon (LC), microbial carbon (Cmic), and carbon fractions of fulvic acid (FA), humic acid (HA) and humin (HU) were determined. The irrigation regime of coffee increased the TOC, LC and Cmic levels and the humified fractions of soil organic matter. In general, the form of P splitting had little influence on the fractions of soil organic matter.

“…O feijoeiro comum é a espécie mais cultivada no mundo entre as demais do gênero Phaseolus, sendo conduzida aproximadamente por dois milhões de produtores dispersos no País, com 64% da produção envolvendo a agricultura familiar em estratos de área inferiores a cinco hectares (STONE et al, 2013).…”

A condutividade hidráulica saturada é uma variável que está relacionada com diversas variáveis físico-hídricas do solo e, por sua vez, pode se apresentar como variável indicadora da qualidade física do desenvolvimento do feijoeiro. O trabalho teve como objetivo estudar a estrutura espacial da condutividade hidráulica saturada e a sua relação com a densidade do solo, a produção de grãos de feijão e seus componentes de produção. O experimento foi realizado em uma área de 134 m2, no campus experimental do departamento de agronomia da Universidade Estadual de Maringá, em Maringá-PR. Foi realizado o cultivo do feijoeiro, avaliando-se no final a produção e os seus componentes, em sequência, foram realizadas medidas de condutividade hidráulica saturada e da densidade do solo nas 181 posições de amostragem. Todas as variáveis analisadas, com exceção do número de vagens, apresentaram estrutura de dependência espacial. A densidade do solo e a produção de grãos são correlacionadas espacialmente com a condutividade hidráulica saturada.

“…The common bean (Phaseolus vulgaris L.) stands out among the agricultural crops in Brazil as a result of the extension of cultivated area, production value and importance as a source of protein for the population (TOLEDO et al, 2009). Bean is cultivated by approximately 2 million Brazilian farmers, being small farmers responsible for 64% of production in areas smaller than 5 hectares (STONE et al, 2013).…”

Essential oils of Tahiti lemon and cinnamon bark in control of storage fungi and the physiological and sanitary quality of beans

et al. 2019

With the objective to evaluate the efficiency of essential oils of Citrus latifolia (Tahiti lemon) and Cinnamomum zeylanicum (cinnamon bark) in the control of plant pathogens Penicillium sp. and Aspergillus sp. and the quality of the bean seeds, two experiments were conducted. In the first one, the effect of essential oils of C. latifolia and C. zeylanicum was evaluated in vitro development of the fungi Penicillium sp. and Aspergillus sp. and, in the second one, the influence of essential oils on the physiological and sanitary quality of bean seeds. The variables mycelial growth, conidial germination and sporulation of Penicillium sp. and Aspergillus sp. were measured in the first experiment, while the seed germination test, first count of germination, germination speed index (GSI) and sanity test of bean seeds were measured in the second. The essential oil (EO) of C. zeylanicum was more efficient than C. latifolia in the control of Aspergillus sp. and Penicillium sp., but decreased the physiological quality of the beans seeds. The fungal diversity identified in the seed health test was composed by fungi of the genera Aspergillus, Penicillium, Cladosporium, Fusarium, Chaetomium and Rhizopus. The results indicate the potential of the use of these EOs in the seeds treatment.
