“…Crop management practices, such as plant staking and sprout thinning, might have positively influenced this result, reducing the period needed for control. This phenomenon might occur because plant staking helps to limit the severity of disease or pest attack (WAMSER et al, 2008), and enhance the distribution of solar radiation across the crop canopy (WAMSER et al, 2007). Moreover, plant staking facilitates the aeration of crops, which increases fruit size and decreases attacks by pests (CECÍLIO FILHO, 2009).…”

-Uncontrolled weed growth interferes with the growth eggplants and crop yields. To control weeds, the main weed species must be identified in crop growing areas and during weed control periods, as weed species might vary in relation to management practices. Therefore, this study aimed to identify the main weed species and determine the periods of weed interference in the eggplant cultivar Nápoli when grown under certain cultural practices, including plant staking and sprout thinning. The experiment was carried out in 2014 using a randomized complete block design, with 3 replications. The treatments consisted of 11 periods of (1) increasing weed control and (2) increasing coexistence of eggplant with weeds from the first day of transplanting (0-14, 0-28, 0-42, 0-56, 0-70, 0-84, 0-98, 0-112, 0-126, 0-140, and up do day 154). Eggplant staking and sprout thinning were performed 42 days after transplanting (DAT). Weed identification and crop yield assessments were performed to determine the Period Before Interference (PBI), Total Period of Interference Prevention (TPIP), and the Critical Period of Interference Prevention (CPIP). The major weeds found in the eggplant cultivar Nápoli were Eleusine indica, Portulaca oleracea, and Cyperus rotundus. Coexistence between the weed community and the eggplant throughout the entire crop production cycle reduced eggplant fruit yield by 78%. The PBI was 29 DAT and the TPIP was 48 DAT, resulting in 19 days of CPIP. Keywords:Competition. Weed community. Solanum melongena L..

Para o controle destas plantas é fundamental identificar as principais espécies infestantes do local de cultivo e os períodos de controle, que podem variar de acordo com as práticas de manejo adotadas. Desta forma, o objetivo deste estudo foi identificar as principais plantas daninhas e determinar os períodos de interferência na cultura da berinjela cultiva 'Nápoli' sob manejo de tutoramento e desbrota. O experimento foi realizado no ano de 2014 no delineamento de blocos ao acaso, com três repetições. Os tratamentos consistiram de 11 períodos crescentes de controle e convivência com as plantas daninhas a partir do transplante: (0-14, 0-28, 0-42, 0-56, 0-70, 0-84, 0-98, 0-112, 0-126, 0-140 e 0-154 dias). As práticas de tutoramento e desbrota ocorreram aos 42 dias após o transplante (DAT). Realizou-se a identificação das plantas daninhas e avaliação da produtividade da cultura para determinação do período anterior à interferência (PAI), do período total de interferência (PTPI) e do período crítico de prevenção a interferência (PCPI). As principais plantas daninhas encontradas na cultura da berinjela 'Nápoli' foram Eleusine indica, Portulaca oleracea e Cyperus rotundus. O convívio entre comunidade infestante e cultura durante todo o ciclo da berinjela reduziu a produtividade de frutos em 78%. O PAI fo...

“…Contrary to this, the CLN11561A recorded the highest number of fruits with symptoms of early blight as a result of the occurrence of micro injuries, having a direct impact on productivity (Table 1). According to Silva et al (2011), the CLN1561A lineage has high productivity (27.13 t ha -1 ), but the incidence of early blight on fruit caused depreciation of their appearance and as a result, caused direct losses in productivity (TOFOLI; DOMINGUES, 2005;WAMSER et al, 2008). The increase in susceptibility to early blight is usually associated with fabrics which have reached maturity, or plants flowering period, fruiting (PEREIRA et al, 2013).…”

-Early blight (caused by Alternaria tomatophila) is a major disease of tomato with no resistant cultivars. Thus, it is necessary to identify sources of resistance and productive genotypes for the development of new cultivars. Therefore, this study aimed to evaluate the productive potential of cherry tomato genotypes grown in the summer / fall, the severity of early blight on leaves and the incidence of disease in fruits. The treatments consisted of Carolina tomato genotypes, Cereja Vermelho, CH 152 and CLN1561A. The experimental design consisted of randomized blocks with six replications, and the experimental plot had 16 plants. The following characteristics were evaluated: area under the disease progress curve (AUDPC), average number of microinjuries on the fruits (MF), average number of fruits per bunch (NFC), average number of bunches per plant (NCP), average number of fruits per plant (NFP), average yield, number of fruits with incidence of early blight per plant (NFI) and the severity of early blight in leaves (%). The cherry tomato genotype CH152 showed tolerance to early blight with a smaller area under the disease progress curve, lower severity and fruits with incidence of A. tomatophila were not observed in this genotype. The CH152 had the highest number of fruits per bunch, greater number of bunches per plant, higher number of fruits per plant and higher productivity. This line has great potential of being integrated into breeding programs.Keywords: Solanum lycopersicum var. cerasiforme. Early blight. Climate conditions. Severity.

The cherry tomato is a vegetable that is gaining great prominence commercially and, for this reason, are being developed alternatives that aim to its production of more sustainable way. Among these alternatives are the use of organic fertilizers and barriers alive. The objective of this study was to evaluate the growth and gas exchange of cherry tomato plants (Solanum lycopersicum var. Cerasiforme) cultivated under different organic fertilizations in an environment with and without alive barrier. The experimental design was randomized blocks with split-plot to the variables leaf area, leaves dry mass and stem dry mass, relative index of chlorophyll, photosynthetic rate, stomatal conductance, transpiration and water use efficiency, being the plots defined by two environments (with or without barrier) and the subplots formed by the sources of organic fertilizer (chicken manure, bovine manure and without fertilization), with five repetitions. As for the variables plant height, stem diameter, used a split-split plot design with sub-subplots formed by the seven evaluation epochs (7, 14, 21, 28, 35, 42 and 49 days after transplanting). When cultivated in alive barrier environment and under fertilization with chicken manure, cherry tomato plants presented higher growth in height and stem diameter, with no difference between the leaf and stem dry masses. In contrast, the without alive barrier environment provided an increase in chlorophyll content and increases of 55.38%, 34.49% and 46.81% in stomatal conductance, photosynthesis and transpiration, respectively. For WUE, the environment with alive barrier was higher in 18.71%.
