which belong to the Tambaú-Verde basin, located in the Northeastern region of São Paulo state. The identification of irrigated areas was performed based on images of the satellite CBERS 2. Mapping was carried out by visual identification of pivots and conversion of the targets of interest into vectors generated by the CCD image, 155/124 orbit-point, acquisition data in 07/21/2007, with space resolution of 20 m and spectral bands 2, 3 and 4. The UTM and SAD69 coordinate systems, spindle 23 South were adopted. The results showed 420 center pivots and the location of higher pivot groupings in each city, amounting to more than 16 thousand hectares of irrigated area. Approximately eight thousand hectares out of this total are located in the sub-basin Tambaú-Verde. Casa Branca city by itself has 188 pivots in more than 9 thousand hectares, which means that 11% of the territorial area of this city is irrigated by the center-pivot system. Images of the CBERS satellite associated with SIG proved to be efficient tools for mapping and monitoring center-pivot irrigated areas.
Coffee leaf rust is the main disease of this crop, however cercosporiosis and coffee leaf miner can also cause significant damage when they reach high levels of infestation. Plant genetic improvement for resistance is one of the best tools for controlling plant diseases. The objective in this work was to identify F 3 progenies of Coffea arabica with resistance to coffee leaf rust, which present a lower incidence and severity of cercosporiosis and coffee leaf miner. The treatments were constituted by 10 progenies, besides two cultivars coffee leaf rust susceptible, used as a control. The experimental design was a randomized block design (RBD), with two replicates, each block consisting of 12 plots randomly distributed, each corresponding to one treatments. The following characteristics were evaluated: coffee leaf rust intensity and severity, cercosporiosis and coffee leaf miner, plants vegetative vigor, grain maturity uniformity and plants height. The progeny averages were grouped by the Scott & Knott test at 5% probability. Progenies 27, 30 and 15 were selected, since they presented low incidence in relation to coffee leaf rust, cercosporiosis and coffee leaf miner, and will be used to continue the breeding program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
