Soil enzymatic activity under coffee cultivation with different water regimes associated to liming and intercropped brachiaria

ABSTRACT: This research evaluated the effects of coffee cultivation with two different water regimes associated or not with liming and the presence/absence of brachiaria as intercrop on the activities of the soil enzymes β-glucosidase, arylsulfatase and acid phosphatase. The study was carried out at the experimental farm of Embrapa Cerrados, using the cultivar IAC 144 (Coffea arabica L.), under a clayey dystrophic Cerrado Oxisol. Two water regimes (WR) were considered, WR1 with irrigation shifts throughout the year and WR3 with controlled water stress, for about 70 days, in the dry season. In each water regime, effects of lime application (with/without) and the presence/absence of brachiaria cultivated between the lines of coffee plants were evaluated. The activities of the enzymes β-glucosidase, arylsulfatase and acid phosphatase were evaluated during the rainy and dry seasons. Liming and intercropped brachiaria positively affected the activities of the three enzymes assessed in this study at varying degrees, depending on season and/or the WR. Our findings evidenced that intercropped brachiaria in coffee rows was the factor that most positively impacted soil enzymes activities.

The aim of this study was to evaluate the effect of irrigation levels on the root system of drip-irrigated coffee plants in western Bahia State (BA), Brazil. The experiment was carried out on Café do Rio Branco farm, located in Barreiras - BA, using adult plants (approximately 3.5 years old) of coffee variety Catuaí Vermelho IAC 144. The experiment was set up as a randomized block design with three treatments corresponding to the irrigation depths of 75, 100 and 150% as determined using Irriplus software. After the fourth harvest, the coffee root system was assessed to determine root length density (RLD) and root weight density (RWD) in different sampled layers. A greater concentration of roots (RLD and RWD) was observed in the surface layer (0-20 cm) and under the lateral line (at 30 and 70 cm from the orthotropic branch). The irrigation depth of 75% provided the highest concentration of roots (RLD and RWD) in the 0-10 cm layer. Keywords: Drip irrigation, Coffea arabica L, root system.

O objetivo deste trabalho foi avaliar os efeitos de diferentes lâminas de irrigação sobre o sistema radicular do cafeeiro irrigado por gotejamento na região Oeste da Bahia. Realizou-se o trabalho na fazenda Café do Rio Branco, localizada em Barreiras - BA em cafeeiros adultos, aproximadamente 3,5 anos de idade, da variedade Catuaí Vermelho IAC 144. O experimento ocorreu no delineamento em blocos casualizados, composto de 3 tratamentos, correspondentes à 75, 100 e 150% da lâmina de irrigação determinada pelo software Irriplus. Após a quarta safra, procedeu-se às avaliações do sistema radicular do cafeeiro, onde foi determinada a densidade de comprimento radicular - DCR e a densidade radicular – DR em diferentes camadas amostradas. Observou-se maior concentração de raízes, DCR e DR, na camada superficial (0-20 cm) e sob a linha lateral (30 e 70 cm de distância do ramo ortotrópico). A lâmina de irrigação correspondente a 75% proporcionou maior concentração de raízes (DCR e DR) na camada de 0 a 10 cm. Palavras - chaves: Irrigação localizada, Coffea arábica L, sistema radicular

Young coffee plants from cultivar Mundo Novo of Coffea arabica were grown without irrigation for 32 consecutive days, to evaluate the effect of leaf water potential on damage caused by low temperatures, under controlled conditions. A wide range of leaf water potentials were evaluated, from - 0.45MPa (wet soil) at the beginning of the experimental period, to - 4.8MPa (severe leaf wilting) at the end. Results showed that under moderate water stress, there was a higher frequency of undamaged plants and lower frequency of severely damaged plants. These results help explain part of the regional variability observed after a frost and stress the importance of new studies associating cold and drought tolerance in coffee.

Xylella fastidiosa (Xf) is a xylem-limited bacterium that is the causal agent of coffee leaf scorch (CLS) in Central America. The purpose of this research was to survey potential vectors of Xf in plantings of coffee, Coffea arabica L., in Puerto Rico. These surveys were conducted from June to November 2006 on four farms, located in the municipalities of Yauco, Juana Díaz and Adjuntas. Insects were collected at each site at 15-day intervals. The 7,423 individuals collected belonged to five families and 12 species. Cicadellidae was the primary family in both number of species and number of individuals. Indexes of dominance, abundance, frequency and constancy showed Agallia pulchra, Apogonalia imitatrix, Caribovia coffeacola and Hortensia similis to be the predominant species. Indexes also showed significant differences among locations, with higher diversity and equitability on Yauco farms, and higher dominance in Adjuntas. Of the four dominant species, Apogonalia imitatrix, C. coffeacola and H. similis are all xylem fluid feeders, and thus may be potential vectors of Xf. Apogonalia imitatrix represents the first report of the species for Puerto Rico.

The total of three consecutive years of fruit production was evaluated in six coffee cultivars (Coffea arabica L.) propagated by seed and grafted onto Robusta (Coffea canephora var. Robusta). The plantations were established at 640 m, 920 m, and 1340 m altitude in the central region of the Veracruz State, Mexico. The coffea plants were established in soils naturally infested with nematodes. Grafted plants had higher production than those propagated by seed. Fruit production was higher at 640 m and 920 m than at 1340 m for the two types of propagation. The cultivars Colombia Brote Café and Colombia Brote Verde had the highest fruit yield regardless of the propagation methods; in contrast, Pacamara, had the lowest. The grafted coffee plants that were planted at 1340 m had a yield reduction of 27% in comparison with those at 640 and 920 m. When the Costa Rica 95 variety was grafted, it achieved fruit yield similar to Colombia Brote Verde and Colombia Brote Café. Pacamara produced almost 28% more fruit when it was grafted onto Robusta.

Coccus viridis (Green) danifica plantas jovens e adultas de Coffea arabica Linnaeu. No entanto, nada se sabe sobre a magnitude dos danos causados por esta praga. Assim, este trabalho teve por objetivo estudar as relações entre o ataque de C. viridis e as perdas causadas por este inseto a C. arabica. Este trabalho foi conduzido em casa de vegetação na Universidade Federal de Viçosa. Foram utilizadas sementes da linhagem IAC 15 da variedade “Catuaí vermelho” de café (C. arabica). Para a confecção dos tratamentos esta praga foi criada em casa de vegetação separada do experimento. Os tratamentos foram: plantas infestadas e não infestadas por adultos e ninfas da cochonilha verde. As plantas foram nutridas com solução nutritiva. Durante 110 dias foram avaliados: números de adultos e de ninfas de primeiro, segundo e terceiro ínstares, área foliar, diâmetro do caule, altura das plantas em todas repetições. No final do experimento avaliou-se o peso das raízes, caule, folhas e total. Os pesos das raízes, matéria seca total, área foliar e diâmetro do caule de plantas não atacadas por C. viridis superaram em 1,31; 1,41; 1,50 e 8,93 vezes, respectivamente o peso de plantas atacadas. As variáveis selecionadas foram: diâmetro do caule (cm), área foliar (cm²), peso de raízes (g), ninfas, adultos e total das cochonilhas. Concluindo que a planta de C. arabica é afetada de forma diferente entre seus órgãos e que a ninfa de terceiro ínstar e adultos são as fases que mais causam danos a C. arabica. Losses Caused by Coccus viridis (Green) (Hemiptera: Coccidae) on Seedlings of Coffea arabica L. Abstract. Coccus viridis (Green) cause losses on seedling and old plants of Coffea arabica (Green). However, nothing is known about of the damages caused by this pest. Thus, the objective of this work was to evaluate the relations between atack of C. viridis and the losses caused by this insect. on C. arabica. This work was conduced in greenhouse at Federal University of Viçosa. Seed coffee plants line IAC 15, variety “Catuaí vermelho” (C. arabica) were used. The insects were reared into greenhouse and separated of the experiment. The treatments were: infested plants and no infested by adults and nymphs of the green scale. The plants were nourished with compound nutrient solutions. For 110 days evaluated: numbers of adults and nymphs of instar first, second and third, leaf area, diameter of stem and plant height in all repetition. At the end of the experiment were evaluated weights of root, stem, leave and total. The weight of root, total dry matter, leaf area and diameter of the stem at plants no attacked by C. viridis were 1.31, 1.41, 1.50 and 8.93 times more than weight attacked plants, respectively. The main variables were: diameter of the stem (cm), leaf area (cm²), weights of root (g), nymphs, adults and all cochineals. Also, parts of the plant (C. arabica) were damaged by nymphs (third) and adults of C. viridis.

SUMMARYWhole branches were removed from trees in the field, at regular intervals, to follow the increase in dry weight of fruits and new vegetative growth. Information on the partition of carbohydrates was gained by comparing the growth of untreated, defoliated, de-blossomed and ring-barked branches. Untreated branches increased in weight rapidly when their fruits began to expand, probably because they imported carbohydrates, and their net photosynthetic capacity increased. More young fruits were shed from defoliated than from untreated branches, thus partially compensating for loss of leaf. Non-fruiting, and sometimes fruiting, branches exported a considerable amount of assimilate during the dry seasons, when the trunk-root system was a relatively important dry matter sink. When there were many fruitless branches on fruiting trees, the fruiting branches imported carbohydrates from them during the whole period of fruit growth, whereas fruitless branches imported carbohydrates only when there was a ‘flush’ of shoot growth.
