| ABSTRACT The normalized dispersion index (NDI) and the b/a index are commonly used to express the stability of aggregates measured by ultrasound. However, few studies have used the critical energy (CE) extracted from modeling to explain the effects of soil use and management on soil aggregation. The objective of this study was to evaluate the influence of soil cover on the CE level required for dispersion of aggregates of a Typic Hapludalf. Soil samples collected from the 0.0-0.05 m depth were evaluated in five different managements with cover plants: perennial soybean (PS), peanuts (P), spontaneous vegetation (SV), black oat/forage turnip (BOFT), and black oat/hairy vetch (BOHV). Aggregates ? 2 mm of the treatments were exposed to ultrasonic irradiation... |

| In a greenhouse experiment, morpho-anatomical and micromorphometrical analyses of two soybean cultivars, MG/BR46 (Conquista) and BR16-tolerant and sensitive to drought, respectively-were used to study their water-deficit-tolerance strategies. Drought treatments were applied at reproductive stages from R2 to R7, where evaluations were conducted at 30 days and 45 days after stress started, respectively. The total length of Conquista plants (shoot + root) was greater than of BR16 plants. Pod dry weight was adversely affected due to the lack of moisture, decreasing productivity even of Conquista plants. Both the cultivars had normal development of root hairs; however, it was observed a decrease in the cortex:central cylinder ratio in BR16 stressed for 30 days,... |

| ABSTRACT Cowpea beans are of great socioeconomic expression for the rural population in North and Northeastern Brazil. This legume is rich in essential nutrients and exhibits great resistance to water stress. However, for grain processing, it is fundamental to study legume behavior during the hydration process. This study aims to evaluate the mass transfer of different cowpea beans via mathematical modeling to determine the viability of hydration for commercialization as a canned product. Physical and chemical analyses of lipids and moisture were performed. The soaking process was performed in a water bath with distilled water at 30, 40, and 50 °C. The mathematical model of Peleg presented satisfactory adjustments, with R2 values ranging between 99.78% and... |

| Foram testadas como cobertura de solo em uma plantacao de cupuacu (Theobroma grandiflorum) com quatro anos de idade, em espacamento de 6m x 6m, as seguintes leguminosas: desmodio (Desmodium ovalifolium), pueraria (Pueraria phaseoloides) e mucuna (Mucuna cochinchinensis). Cada leguminosa ocupou 1ha de uma area infestada de capim taripucu (Paspalum maritimum Trin.). Inicialmente, por avaliacao visual, notou-se que a mucuna recobriu bem o solo, mas desapareceu rapidamente, por apresentar comportamento anual, permitindo a reinfestacao das plantas invasoras, apos completar seu ciclo de vida. Desmodio teve crescimento lento no inicio, havendo predominancia do capim taripucu. Pueraria foi a mais eficiente em cobrir o solo, controlando a graminea, promovendo assim... |
