The wines of the Sao Francisco Valley, in the northeast of Brazil, are the only ones in the world produced under semi-arid tropical conditions. This study shows results related to the 4th production cycle for the physiological and agronomic traits of the ?Syrah? grapevine subjected to the practices of defoliation and topping. The experiment was carried out in 2012 in a commercial vineyard of the ?Syrah? cultivar grafted onto the rootstock ?IAC 766? drip irrigated for five years. Treatments consisted of combinations of the practices of leaf removal of basal leaves above the last bunch, applied once at the beginning of the berry touch stage, and shoot topping applied intwo stages: ?pea?-sized grain and the beginning of berry touch. The control (T1)consisted of the same canopy management adopted on the farm, which was two leaf removals and one early topping. The experimental design was randomised blocks with four replications. The fresh matter weight of shoots was not affected by leaf removal and topping, although the leaf fresh matter weight differed significantly among treatments. Plants subjected to treatment T2, leaf removal and no topping showed greater production than those subjected to T5, leaf removal and topping in stage 1. Greater mass of the bunch was obtained in T8, with no leaf removal and topping in stage 1. The average Ravaz index was 7.5, showing a good balance between vegetative growth and fruits. The effects of leaf removal and shoot topping on gas exchange were analysed through photosynthesis, stomatal conductance and water use efficiency after 15 days of treatment application until the ripening stage using IRGA (model Li -6400 XT). From the standpoint of leaf gas exchange, leaf removal and shoot topping practices did not affect the plants. It is up to the grower to adopt the technique that leads to lower operating costs by ensuring good photosynthetic rates and, consequently, improved grape quality for winemaking.

ABSTRACT - The objective of this work was to evaluate the influence of different soil coverings, fertilizer types, and soil conditioners on the incidence and severity of brown eye spot (Cercospora coffeicola) in coffee (Coffea arabica) during the vegetative stage. The experiment was carried out in a randomized complete block design, in a 3×2×5 factorial arrangement (soil coverings × fertilizer types × soil conditioners) in subdivided plots, with three replicates. Comparisons were made among: three soil covering (plastic film, Urochloa decumbens, and no covering) in the plots; two fertililizer types (conventional and controlled release) in the sub-plots; and four soil conditioners (coffee husk, agricultural gypsum, water retention polymer, and organic compound), as well as the control, in the sub-sub-plots. The area under the progress curve for disease incidence and severity showed the lowest mean without soil covering, whereas that for number of leaves was greater with the use of the controlled-release fertilizer. The plastic film provided a greater soil moisture and a lower soil resistance penetration. The chemical composition of the organic compound reduced coffee plants growth. Soil covering with plastic film or U. decumbens favors the high incidence of brown eye spot; however, it provides a greater soil moisture and, therefore, improves the growth of coffee plants in the vegetative stage. RESUMO - O objetivo deste trabalho foi avaliar a influência de diferentes coberturas de solo, tipos de fertilizantes e condicionadores de solo sobre a incidência e a severidade da cercosporiose (Cercospora coffeicola) em cafeeiro (Coffea arabica), em estádio vegetativo. O experimento foi realizado em delineamento de blocos ao acaso, em arranjo fatorial 3×2×5 (coberturas de solo × tipos de fertilizantes × condicionadores de solo) em parcelas subsubdivididas, com três repetições. Foram feitas comparações entre: três coberturas de solo (filme plástico, Urochloa decumbens e sem cobertura) nas parcelas; dois tipos de fertilizante (convencional e liberação controlada) nas subparcelas; e quatro condicionadores de solo (casca de café, gesso agrícola, polímero hidrorretentor e composto orgânico), bem como o controle, nas subsubparcelas. A área abaixo da curva de progresso da incidência e da severidade da doença mostrou as menores médias sem cobertura do solo, enquanto a do número de folhas foi maior com o uso do fertilizante de liberação controlada. O filme plástico proporcionou maior umidade do solo e menor resistência à penetração do solo. A composição química do composto orgânico reduziu o crescimento do cafeeiro. A cobertura do solo com filme plástico ou com U. decumbens favorece a alta incidência da cercosporiose; no entanto, proporciona maior umidade do solo e, consequentemente, melhora o crescimento do cafeeiro na fase vegetativa.
