Type Of Management

(1) Background: Degradation of soils and erosion have been described for most of the soils presented along the Maule Valley. Organic and integrated management promotes agroecosystem health, improving soil biological activity. Due to this, the aim of this research was to study the effect of organic, integrated, and conventional management on the productive, oenological and soil variables of a vineyard cultivated under semiarid conditions during 5 consecutive seasons; (2) Methods: Yield, grape and wine oenological, and soil physicochemical parameters were evaluated. Bioclimatic indices were calculated in the studied seasons; (3) Results: Conventional management allowed to improve yield and the number of bunches per vine compared to organic management. However, this latter enhanced mineral nitrogen and potassium content in soil. Based on bioclimatic indices, heat accumulation improved number of bunches per plant and most of the soil physicochemical parameters; (4) Conclusions: Organic management improved the accumulation of some microelements in soils at the expense of yield. Organic matter decreased along the study was carried out. Season was the conditioning factor of the variability of most of the studied parameters, while the interaction between season and type of management affected soluble solids, probable alcohol and pH in grapes, and total polyphenol index and pH in wines.

The aim of this work was to investigate the effect of meteorological conditions on resveratrol concentration of red wines produced in Piacenza viticultural region (Italy). In this regard, six representative estates producing Colli Piacentini Gutturnio DOC (a blend of V. vinifera L. cvs. Barbera and Croatina) vintage wines were analysed for trans- and cis-resveratrol over an 8-year period (1998–2005). Grapes were taken from the same vineyard in each estate by using the same enological practices over the entire investigated period. The meteorological conditions corresponding to the production areas were recorded, and bioclimatic indices were calculated as well. Overall, cis-resveratrol concentration was negatively correlated to Huglin index and August mean temperature, whilst positive correlation coefficients were found when considering the Selianinov index and the rainfall of September.

Rot and damage caused by post-harvest phytopathogenic fungi affect fruit quality. Essential oils (EO) are considered as an alternative to fungicides. Postharvest diseases of fruits may also be controlled by the bagging approach and the use of antimicrobial packaging. Based on the beneficial properties of EO and the concepts of bagging and antimicrobial packaging, this study aimed to develop sachets containing EO to be used as part of an antimicrobial packaging system. The activities of oregano, cinnamon and lemon grass EO were evaluated testing the sachets in vitro against the phytopathogenic fungi Alternaria alternata, Fusarium semitectum, Lasiodiplodia theobromae and Rhizopus stolonifer. The effects of the sachets on the microbiological and physicochemical parameters of post-harvest papaya were also evaluated. Both pure and sachet-incorporated EO showed antifungal activity in vitro against all tested fungi. For papaya, sachets containing cinnamon, oregano and lemon grass showed a significant reduction in the growth of mesophilic aerobic bacteria, yeasts and mould, with the cinnamon sachet causing the greatest reduction in microorganisms at the end of the storage time. Physicochemical parameters of papaya, such as weight loss, colour, firmness, total soluble solids/titratable acidity ratio and pH were not significantly altered by the presence of EO sachets, thus not affecting the natural ripening process of the papaya.

Viticultural climatic indices were assessed for the evaluation of the meteorological variations in the requirements of wine cultivars. The applied bioclimatic indices have been widely used to provide an initial evaluation of climate change impacts on grapevine and to delineate wine regions and suitable areas for planting around the world. The study was carried out over a period of 16 years (from 2000 to 2015) in five Designation of Origin areas in Northwestern Spain located in the Eurosiberian region, the transition zone between the Eurosiberian and the Mediterranean areas, and in the Mediterranean area. In addition, the high-resolution meteorological dataset “Spain02” was applied to the bioclimatic indices for the period 1950–2095. To further assess the performance of “Spain02”, Taylor diagrams were elaborated for the different bioclimatic indices. A significant trend to an increase of the Winkler, Huglin, Night Cold Index and GSS Indices was detected in the North-western Spain, whereas slight negative trends for BBLI and GSP Indices were observed. To analyze future projections 2061–2095, data from the high-resolution dynamically downscaled daily climate simulations from EURO-CORDEX project were used. To further assess the performance of Spain02, Taylor diagrams were elaborated for the different bioclimatic indices. A trend to an increase of the Winkler, Huglin, Night Cold Index and GSP Indices was detected in Northwestern Spain, whereas slight negative trends for BBLI and GSP Indices were observed. Our results showed that climatic conditions in the study region could variate for the crop in the future, more for Mediterranean than Eurosiberian bioclimatic area. Due to an advance in the phenological events or the vintage data, more alcohol-fortified wines and variations in the acidity level of wines could be expected in Northwestern Spain, these processes being most noticeable in the Mediterranean area. The projections for the BBLI and GSP Indices will induce a decrease in the pressure of the mildew attacks incidence in the areas located at the Eurosiberian region and the nearest transition zones. Projections showed if the trend of temperature increase continues, some cultural practice variations should be conducted in order to preserve the grape cultivation suitability in the studied area.

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

AbstractCanadian Western Hard Red Spring (CWRS) wheat is recognized as premium quality wheat, ideal for breadmaking due to its superior milling qualities, baking characteristics and protein content. Organic wheat production is becoming more prevalent in Canada, due to increasing consumer demand for organic wheat products. Differences may exist in the baking and milling quality of wheat grown under conventional and organic management, a result of the dissimilarity between organic and conventional soil and crop management practices. Five CWRS cultivars released from 1885 to 1997 were grown under conventional and organic management and were assessed for their breadmaking potential. Several traits were investigated, including test weight, protein content, flour yield, kernel hardness and several mixograph parameters. Test weight was higher under conventional management, while no differences in protein content were observed between organic and conventionally grown wheat. Higher sodium dodecyl sulfate sedimentation (SDSS) volume, a reflection of gluten strength, was observed under conventional management, while there was a trend towards higher dough strength under organic management. Cultivars differed in grain protein, flour yield, kernel hardness and mixograph parameters, with Park and McKenzie superior to the others, particularly Red Fife, a much older cultivar. Management×cultivar interaction effects suggest that cultivars exhibit somewhat different baking characteristics when grown in the two management systems. There was no evidence that older cultivars (developed prior to the widespread use of pesticides and fertilizers) are better suited, in terms of breadmaking quality, for organic production.

Abstract Nowadays the study of the interrelation of the genotype of strawberry plants in garden and climatic conditions is extremely relevant. Due to the various systems of genetic control and the modifying effects of growing conditions on the manifestation of quantitative traits, there is the need to assess the genotypic variability of economically valuable features, focused on the identification of genotypes characterized by stability and adaptive qualities in growing conditions. The study examined 15 varieties of garden strawberries of domestic and foreign selection. The field experiments and surveys were carried out according to the Program generally accepted in the Russian Federation and methodology for the variety study of fruit, berry and nut crops. We studied such features as the number of peduncles (pcs/bush), number of berries (pcs/bush), average weight of berries (g), total and marketable yield (g/bush), sugar content in berries, soluble solids and ascorbic acid. The purpose of this work was to assess the genotype-year interrelation in terms of the variability of productivity features and berry quality and to identify strawberry varieties with a stable genotype. As a result of two-way analysis of variance for the variety-year interrelation, the obtained values were 1.10-8.50 at standard Fst. - 1.24. Statistically important differences had indicators of productivity of a bush between the first and second clusters (t = 5.89 at p <0.01), the first and third (t = 15.83 at p <0.01), the second and third clusters (t = 8.13 at p <0.01), as well as the average berry weight between the first and third, second and third clusters (t = 15.50 and 6.99 at p <0.01, respectively). Significant differences in the value of the Euclidean distance were revealed for varieties Mishutka (54.5), Daryonka (54.5), Pervoklassnitsa (58) realizing their productivity potential in different years of cultivation.

Experience of the Central Asia countries in the sphere of reorming of institutional structures responsible for water resources management has been investigated. The outcomes of the works aimed at studying of the results of the integrated management principles application in order to improve structures and methods of water resources management are presented. These outputs enable to reveal special features of the approaches to the management problems solution in the conditions of available water resources abundance and lack in countries with different economic and natural/climatic conditions. The experience was summed up and the typical trends in the water sector management improvement accumulated in the Central Asia countries, as well as the date from other countries with the similar problems including NICs with centralized administrative systems, regions with the many-century traditions of irrigation farming, as well as the countries of transitional economy were revealed. Studying of many countries’ experience concerning adiption of the water resources integrated management allows us to state that there is no sungle ideal or universal model of transition from spatial/territorial management to basin management, no model which can be applied to any country. Analysis of the water resources management systems and institutions enables to formulate the main conditions for effective application of water resources integrated management principles. The paper notes that in spite of substantial progess in water resources management attained in the Central Asia countries many problems including practical application of water legislation, taking into account interest of all sectors of national economy, better coordination between ministeries and agencies involved in water resources management, participation of all stakeholders in taking decisions concerning water supply projects, distribution of juridical and financial obligations between water users and government, and insufficient coordination and agreement in actions at international, national andregional levels stay unsolved.

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>

Objective: To identify the morphometric and biochemical variation in mango fruits var. Ataulfo (Mangifera indica L.) in two contrasting environments with and without conventional management. Design/methodology/approximation: Morphological and biochemical variables were studied in mango fruits var. Ataulfo in two environments, one of them (La Norteña) with Leptosol soil and Aw climate with conventional agrochemical-based management and the other (Santa Cecilia) on Acrisol soil and Am climate with agroecological management. There were 30 fruits used, all from five trees (n=150) per study garden in a state of commercial maturity. Each fruit was considered as an experimental unit, and morphological and biochemical variables were evaluated for each fruit. Results: Increase in fruit weight, higher pH and increase in total soluble solids, but decrease in pulp weight on site with conventional handling. Increase in pulp content and firmness in fruits from the site without handling. Study Limitations/implications: Changes in the amount and distribution of rainfall in both environments each year. Findings / conclusions: Morphological and biochemical modifications are presented. Greater size and weight, pH and TSS content in the conventional production system, but increased pulp and greater firmness, as well as higher citric acid content in the agroecological system. The results suggest differential effects in mango fruits according to the management and environment where they develop.

Abstract Fruits and vegetables are important sources of nutrients for mankind. Among the various fruits available in Bangladesh, mango occupies a vital place in the human nutrition for its delicious taste and higher nutritious value. In this study, five mango varieties, viz. Fazli, Amrupali, Langra, Gopalbogh and Misribogh, were tested to evaluate the quality of these mango varieties available in Northern Bangladesh. Physiochemical characteristics, including moisture, ash, total carbohydrates, total solids, total soluble solids (TSS), pH, acidity, total sugars and ascorbic acid contents were evaluated. The results showed that there were significant (p< 0.05) differences among mangoes of all varieties for physicochemical parameters. In case of proximate composition, the mango variety Amrupali showed the highest ash content (2.34±0.15) and fat content (1.18±0.13). Protein content (0.94±0.12) and total fiber (2.67%) content was shown to be the highest by Gopalbogh and Misribogh, respectively. The selected mango varieties contained TSS of 12.87~20.55oBrix, pH of 4.45~4.67, titrable acidity of 0.07~0.42%, reducing sugar of 8.40~15.43%, non-reducing sugar of 9.24~10.48%, and total sugarof 18.88~25.12%. The study findings would be helpful for the consumers, dietitian and industry policymakers.
