Coeficientes de cultura (Kc) e crescimento vegetativo de Acaiá Cerrado associados a graus-dia de desenvolvimento  Moisés Santiago Ribeiro; Elio Lemos da Silva; Débora Candeias Marques de Moura; Antônio Augusto Aguilar Dantas2Departamento de Engenharia, Universidade Federal de Lavras, Lavras, MG, [email protected]  1 Resumo Há uma tendência de utilização de variáveis meteorológicas que considerem o efeito climático sobre a duração das fases e desenvolvimento da cultura, como base para estabelecer os coeficientes de cultura (Kc). Este estudo teve por objetivo determinar os Kc e o crescimento vegetativo do cafeeiro (Coffea arabica L.), cultivar Acaiá Cerrado MG-1474, estabelecendo uma relação com graus-dia de desenvolvimento (GDD). O trabalho foi conduzido na área experimental da Universidade Federal de Lavras (UFLA), no município de Lavras-MG. A partir dos valores de evapotranspiração de referência (ETo) e evapotranspiração da cultura (ETc), determinaram-se os Kc. Foram realizadas avaliações de crescimento vegetativo e estabelecida a relação com as somas térmicas ou GDD. Apesar do bom ajuste do modelo linear aos dados de crescimento vegetativo em relação aos GDD, houve o efeito das datas de plantio sobre o crescimento da cultura. Os valores de coeficientes de cultura (Kc) estimados pelo modelo desenvolvido para as condições de Lavras foram de0,73 a 1,25 correspondentes aos intervalos de 700 GDD.         UNITERMOS: Coffea arabica L., balanço hídrico, evapotranspiração máxima.  RIBEIRO, M.

A.COEFFICIENTS OF CULTURE (KC) AND VEGETATIVE GROWTH OF ACAIÁ CERRADO ASSOCIATED TO GROWTH DEGREES-DAY   2 Abstract There is a tendency in using meteorological variables that consider the climatic effect on the durations of the culture development phases in order to establish the crop coefficients. This study aimed to determinate the crop coefficients and the vegetative growth of the Acaiá Cerrado MG 1474 coffee plant (Coffee arabica L.) establishing a relation with the growth degree-day (GDD). The work was carried out in the experimental area of the Department of Engineering of the “Federal University of Lavras”, Lavras, MG. By using the values of the reference evapotranspiration and the crop evapotranspiration, the crop coefficients were determined. Vegetative growth evaluations were made and a relation with the thermal sums or growth degree-day was done. Despite the good adjustement of the third-degree linear model using the data of crop coefficients related to growth degree-day, there was the effect of the planting dates on the culture growth. The crop coefficient values estimated by the model developed for the conditions of Lavras ranged from 0.73 to 1.25, corresponding to the intervals of 700 growth degrees-day.KEYWORDS: Coffea arabica, hydric balance, maximum evapotranspiration

AbstractPratylenchus coffeae is a parasitic nematoda that infected the roots of some plants, one of them is coffee. The Infection of Pratylenchus coffeae cause root tissue damage that led to root lession and make root become rotten, it will interfere the ability of roots to absorb water and nutrients in the soil which resulted in the growth of plants. At the moment, control of Pratylenchus coffeae are following integrated pests management (IPM) program, which integrated between the use of coffee resistant clone and application of biological agents. Research on biological control was conducted more intensive, at the moment; due to it is friendlier save against environment and cheaper then using chemical nematicides. The research was conducted to know the effects of Micorrhiza Helper Bacteria (MHB),Pseudomonas diminuta and Bacillus subtilis in suppressing the population of P. coffeaeas well as their effect on growth of coffee seedling.  Coffee arabica (Coffea arabica L.) seedling one moth old were used in the experiment. The experiment prepared with eight treatments and five  replications, as follows: A (Pseudomonas diminuta with density of 108 cfu / ml), B (Pseudomonas diminuta with density of 2x108 cfu / ml), C (Bacillus subtilis with density of 108 cfu / ml ), D (Bacillus subtilis with density 2x108 cfu / ml), E (Carbofuran nematicide 5 g formulation / pot), F (Pseudomonas diminuta and Bacillus subtilis with each density of 108 cfu / ml), K- (Nematoda inoculation but without bacteria and nematicide), K+ (coffee seedling  without any additional treatment). The experiment was conducted for sixteen weeks or about four months. The results of the experiment showed that application of MHB could suppress population of P. coffeae and increase coffee seedling growth significantly. Inoculation of B. subtilis at 108 cfu per seedling suppressed significantly nematoda population of 71.3% compared with untreated seedling but inoculated with nematoda. It was not significant different with carbofuran treatment which could suppress nematoda population by 89.7%. The same result also occur on the treatment of P. diminuta at density level 2.108 cfu/seedling, which could suppress nematoda population by 64.2%. Seedling growth were treated with MHB also significantly increase compared with seedling without treatment and inoculation of nematodas, especially on the treatment of B.subtilis at density level 108 cfu and P.diminuta at density level of 108 cfu, with increasing level of 35.4% and 34.2 %, respectively.Keywords: MHB (Mycorrhiza Helper Bacteria), Arabica coffee (Coffea arabica L.),  Pratylenchus coffeae, Bacillus subtilis, Pseudomonas diminuta.

EVAPOTRANSPIRAÇÃO E COEFICIENTES DE CULTURA DO MARACUJAZEIRO AMARELO CONDUZIDO SOB DUAS ORIENTAÇÕES DE PLANTIO  Tonny José Araújo da Silva; Marcos Vinícius Folegatti; Cláudio Ricardo da Silva; José Alves Júnior; Regina Célia de Matos PiresDepartamento de Engenharia Rural-Irrigação e Drenagem, Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo, Piracicaba, SP, [email protected]   1 RESUMO O Brasil é o maior produtor mundial de maracujá (Passiflora edulis Sims. var. flavicarpa Deg.), empregando no campo entre 100 a 250 dias homem ha-1 ano-1, sendo o terceiro suco mais produzido no Brasil. Nos cultivos irrigados de maracujazeiro obtêm-se as maiores produtividades, melhor qualidade de frutos e preço de mercado, porém, ainda são poucas as informações sobre evapotranspiração e coeficientes de cultivo necessários ao manejo de irrigação na cultura. Dessa maneira, objetivo deste estudo foi determinar a evapotranspiração (ETc) e o coeficiente de cultivo (Kc) do maracujazeiro amarelo, conduzido em espaldeira com orientação Norte-Sul e Leste-Oeste. Este trabalho foi conduzido no período de dezembro de 2003 a janeiro de 2005, em Piracicaba, SP. Mudas de maracujazeiro amarelo, com 83 dias de germinação, foram transplantadas para duas parcelas experimentais definidas pela direção da espaldeira. Para a estimativa do consumo de água pelas plantas, utilizaram-se 4 lisímetros de pesagem hidráulica. A ETc total aos 450 dias após o plantio (DAP) foi de 1171 mm e 1083 mm acumulados para as parcela Norte-Sul e Leste-Oeste, respectivamente. Os valores extremos de consumo foram em média 5 L planta-1 dia-1, durante o outono e inverno, e 8 L planta-1 dia-1, no Verão. Não houve diferença significativa para a ETc das parcelas nos meses de menor disponibilidade energética. Os coeficientes de cultivo obtidos foram: 0,6 para crescimento vegetativo apical, 0,9 para crescimento vegetativo lateral, 1,2 para floração e frutificação, 1,0 para maturação dos frutos e 0,8 para a fase pós-maturação dos frutos. UNITERMOS: Passiflora edulis, lisímetro de pesagem hidráulica, manejo de irrigação.  SILVA, T.

C. de M.; EVAPOTRANSPIRATION AND CROP COEFFICIENTS OF YELLOW PASSIONFRUIT TREES CULTIVATED IN TRELLIS UNDER TWO ORIENTATIONS  2 ABSTRACT Brazilis the largest producer of passion fruit (Passiflora edulis Sims. var. flavicarpa Deg.), using between 100 to 250 days manpower ha-1 year-1. Its juice is the third most produced one. Irrigation is an important practice for passion fruit crop providing higher productivity, better fruit quality and market price. However, information about crop evapotranspiration and crop coefficients for this crop is still not very known. Therefore, the objective of this work was to determine the passion fruit crop evapotranspiration (ETc) and crop coefficient (Kc) cultivated in trellis with North-South and East-West orientations. The experiment was carried out in Piracicaba, São Paulo State, Brazil, from December 2003 to January 2005. 83-day-old passion fruit seedlings (Passiflora edulis Sims f. flavicarpa Deg cv. IAC 275) were transplanted to the experimental area. 4 hydraulic weighing lysimeters were used in order to estimate the crop evapotranspiration. Total ETc at 450 days after transplant (DAP) for North-South orientation area was higher  (1.171 mm) than for East-West orientation (1,083 mm). No significant differences were found for ETc between orientations during the months with lower net radiation. Crop coefficient values were: 0.6 for apex vegetative growth, 0.9 for lateral vegetative growth, 1.2 for flowering and fruit development, 1.0 for fruit maturation and 0.8 for post-maturation period. KEYWORDS: Passiflora edulis, hydraulic weighing lysimeter, irrigation scheduling

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.
