Duration Of Storage

Numerous apple varieties have been tested parallel with traditional Jonathan varieties during four years, 1990-1994 on three different geographical areas of Hungary. The picking time took place at three different times in a year: ten days before the probably optimal picking time, at close-to-optimal picking time, and ten days after the optimal picking time. The effect of storage on quality of fruits have been tested in February, March, and April under circumstances of a semi-industrial storage experiment. The results of experience can contribute to answer numerous current, from point of view of practice important topics: The stochastic relations between various fruit quality parameters at different varieties The change of fruit — quality during storage The effect of different picking date on storage losses The possibilities of storage — loss predicting by the utilization of multiple regression analysis. The most important results of experiences are as follows : The starch — degradation test and Streiff — index are well applicable for practical purposes to determine the optimal harvest-date. On base of analysis of various losses and physiological diseases the high importance of mass loss is obvious. In the variety Jonnee the earlier picking date considerably increased the mass loss. The effect of variety on mass loss is rather limited. In the Jonathan varieties the Jonathan spot was a rather important physiological disease. The late picking time increased the frequency of Jonathan - spot. At optimal date of harvest at Jonnee the frequency of Jonathan -spot was lower, than at Jonathan M 41. In the Jonathan M41 and Jonnee the importance of scald was rather limited, but in the Wellspur Delicious and Smoothee this disease occurred relatively frequently. In the Smoothee the earlier picking time considerably increased the probability of scald. The multiple regression analysis yielded reliable results, fit for prediction of storage losses and diseases on the base of chemical and physical properties, determined at the time of picking.

<p>A tecnologia de mulching é uma ferramenta que possibilita a redução de gastos para os produtores no tocante a utilização de agroquímicos, água de irrigação e a utilização de mão-de-obra, além de promover melhoria na qualidade da fruta produzida e o aumento da produção. O presente trabalho objetivou avaliar os impactos provocados pelo uso do mulch no meio ambiental, social e econômico de uma comunidade rural de Mossoró/RN. Fez-se o uso de observações, entrevista semiestruturada e questionário estruturado, o qual foi aplicado a 12,5% dos participantes de um total de 32. Os resultados mostram que essa tecnologia é utilizada por todos os produtores, com o intuito de melhorar a produção do melão em quantidade e qualidade.  Contudo, o uso do mulch de polietileno, utilizado nessa técnica, acarreta preocupações quanto ao seu descarte pós-uso, com a utilização de práticas arcaicas como as queimadas que afetam de forma gradual a saúde do trabalhador e as propriedades biológicas do solo.</p><p><strong><em>The impacts of mulching </em></strong><strong><em>technology used in melon cultivation in Mossoró region</em></strong><strong><em></em></strong></p><p><strong>Abstract</strong><strong>: </strong>The mulching technology is a tool that enables cost reduction for producers regarding the use of agrochemicals, irrigation water and the use of labor force, promoting improvement in the produced fruit quality and increasing production.

Observation, semi-structured interview and structured questionnaire were used in the study, and the questionnaire was applied to 12.5% of participants from a total of 32. The results show that this technology is used by all producers, in order to improve the production of melon in quantity and quality. However, the use of polyethylene mulch utilized therein causes concern as to their post-use disposal, with the use of archaic practices, such as burning, that gradually affect workers' health and biological properties of the soil.<strong></strong></p>

Catch Mechanism

Abstract. Damaged fruit is the most important barrier to success in the mechanical harvesting of fresh market apples using mass harvesting methods. To address fruit quality issues and expedite the commercialization of mechanical harvesting of fresh market apples, an innovative air suspension-based catching (ASC) mechanism was designed and fabricated to collect fruit detached with a mechanical shaking device (tree limb shaker). The objective of this study was to evaluate the shake-and-catch mechanism in mechanical harvesting of apples. Three apple varieties with different physical characteristics (‘Honeycrisp’, ‘Pacific Rose’, and ‘Pink Lady’) were used in the field trials. The air pressure settings for the ASC mechanism played an important role in reducing the risk of apple damage and improving fruit quality. The effect of the shaking frequency of the tree limb shaker on fruit quality was not significant. When the air pressure increased from 0 to 1030 kPa, the fruit quality greatly improved. Keywords: Air pressure, Air suspension-based catching mechanism, Fluidized bed technology, Fresh market apples, Fruit quality, Mass harvesting, Shaking efficiency.

The Relationship

Large shocks to local labor markets can cause long-lasting changes to employment, unemployment, and the local labor force. This study examines the relationship between mass layoffs and the long-run size of the local labor force. The authors consider four main channels through which the local labor force may adjust: in-migration, out-migration, retirement, and disability insurance enrollment. These channels, primarily out-migration, account for more than half of the labor force reduction over the past two decades. Findings show, however, that during and after the Great Recession, instead of out-migration, non-participation in the labor force grew to account for most of the local labor force exits following a mass layoff.
