Water availability is predicted to be reduced and temperature to rise in the global climate change context. Future climate conditions may thus represent a serious risk for coffee cultivation especially in less favorable environment. Agroforestry has been postulated as a promising strategy to adapting to climate changes. Shade tree may minimize radiation and temperature near the soil surface and reduce soil evaporation. Shade tree may enhance infiltration, reduce runoff and increase rainfall water use efficiency by taking up water from deep soil layers. However, shade tree may reduce the water that reaches the soil by rainfall interception. Trees may consume additional water and can establish a competitive relationship depending on tree species characteristics, soil water availability, site conditions and management.
In this experiment water dynamics and use was monitored in a mature agroforestry experiment where coffee shaded by a mixture of Tabebuia rosea and Simarouba glauca is compared to full sun coffee over 2012 and 2013. The water balance was obtained by two independent approaches: 1) measuring directly all components of water balance (trees and coffee transpiration; soil evaporation; rainfall interception); and 2) measuring changes in the soil water stock through Time Domain Reflectometers (TDR) probes.
Agroforestry (AFS) showed greater transpiration and lower soil surface evaporation compared to full sun (FS). Shade tree did not represent a serious constraint for coffee water use during most of the period of the experiment. Coffee water consumption represented 75% of the total transpiration in agroforestry while Tabebuia rosea transpired 17% and Simarouba glauca 8%. Complementarity was demonstrated by root niche differentiation between coffee and Simarouba glauca that seemed to be more suitable as coffee shade tree compared to Tabebuia rosea. We also demonstrated high competition between coffee and shade tree when an atypical very dry season occurred. Transpiration was stabilized although the high evaporative demand and coffee leaf water potential reached its lowest value in AFS which suggested high level of coffee water stress. Adaptation strategies for coping with climate change using shade trees need to be devised taking into account this quantified information into account.

O mamoeiro (Carica papaya L.) representa uma das principais frutíferas tropicais cujo cultivo é difundido por diversas regiões do mundo. Entretanto, um dos grandes entraves na expansão do cenário produtivo são doenças que acometem a cultura. Dentre as doenças, se destacam a pinta preta
e de mancha-de-corynespora, doenças fungicas causadas pelos agentes Asperisporium caricae e Corynespora cassiicola, respectivamente. Diante disso, o objetivo deste estudo foi avaliar o efeito de diferentes fungicidas no controle químico destas doenças. Foram testados 13 tratamentos compostospor quatro fungicidas comercial, aplicados em três diferentes dosagens e uma testemunha com ausência de produtos. O delineamento experimental utilizado foi em blocos casualizados, com 5 blocos e 10 parcelas (plantas), totalizando 650 plantas no campo experimental. Foi avaliado efeito das doenças nas plantas de mamoeiro através da área abaixo da curva de progresso obtida a partir de três folhas de cada planta. Os dados foram submetidos a análise de variância a 5% de probabilidade e as médias comparadas pelo teste de agrupamento de Scott-Knott, a 5% de probabilidade. Todos os fungicidas em todas as dosagens se mostraram eficazes no controle de pinta preta e mancha-decorynespora em plantas de mamoeiro. |
