Abstract Two experiments were carried out to evaluate the relationship between dry matter content (DMC) and maturity index of ‘Fuji’ apple fruit sports (‘Mishima’, ‘Fuji Select’ and ‘Fuji Suprema’) during the final stage of fruit growth, and the relationship between DMC at harvest and the post-harvest fruit quality. Fruit were harvested from orchards of three regions (Caçador, São Joaquim and Vacaria), on two rootstocks (M9 and Marubakaido with M9 interstock). In experiment 1 (2014), fruit were periodically sampled beginning 83 days before the commercial harvest period. In experiment 2, fruit were harvested at optimum maturity for long-term storage and stored in air at 0.5 ºC (2014) or after optimum maturity for long-term storage and stored in controlled atmosphere at 0.7 ºC (2014 and 2015). Apple fruit maturity on the tree was characterized by decreased flesh firmness and increased starch index and soluble solids content (SS) and by a small change in DMC. DMC at harvest was correlated with flesh firmness and SS in one of two years, but DMC was not correlated with the incidence of disorders after storage. The results show that DMC at harvest is not suitable as a maturity index of ‘Fuji’ apples, and its use as a post-harvest quality predictor is not consistent between crop years.

Indonesia is the third largest rice producer in the world, at the same time it’s a country that imports rice from various countries. The government has provided input subsidies to increase rice production and reduce imports. Modes of rice farming in Indonesia is relatively diverse, from conventional to modern, even in the post-harvest process. The objectives of this study are: to analyze the impact of post-harvest handling on food loss and to analyze the relationship between paddy or rice loss with the quantity and value of fertilizers subsidy and paddy production in Indonesia. The estimated food (rice) loss includes the stages of harvesting, threshing, drying, and milling stages and distribution. Farmers use various technologies in processing rice: serrated sickle in harvesting, power thresher in threshing, and flatbed dryer in drying; while rice milling was done using conventional rice miller. The total rice loss reached 6.91 million tons in 2014 and continued to increase to 8.14 million tons in 2018. The growth rate of fertilizer subsidy value is higher than those of subsidized fertilizer quantity and paddy or rice loss. The results indicated that growth rates of paddy production and rice loss was lower than increased of government subsidy for fertilizer.

Crop yields have decreased globally due to declining investments in research and infrastructure, which are preconditions for food security. The study established the Influence of Post-Harvest technology on Food Security in Narok East sub-County, Kenya, which is a rural sub-County in Narok County. A descriptive research design was adopted by the study. The target population is comprised of 25078 households distributed proportionally in the four wards and is involved in different farming activities. A sample of 378 household heads was determined using the sample size determination formula. Primary data was collected using a questionnaire and an interview guide. Data analysis was done using descriptive statistics of frequencies, percentages and inferential statistics of correlation, ANOVA and regression analysis. The results were presented using frequency and percentages, tables and charts. The relationship between the variables was tested at a significant level of 0.05. The results show that there is a strong, positive and significant correlation between post-harvest technology and food security in the sub-County (r = .606** and p-value = 0.000). This implies that the relationship between the variables is very significant hence post-harvest technology is a strong determinant of food security in the study area. The study concludes that ANOVA model indicated a very significant and statistical relationship between post-harvest technology and food security. The study is beneficial to all the stakeholders in rural areas in Kenya who have consistently experienced food insecurity as it will provide appropriate data that will be used for policymaking.

Purpose The study provides an insight into the application and usefulness of activity management (AM) principles in an environmental context. Specifically, the purpose of this paper is to examine the extent of use of environmental activity management (EAM) utilising Gosselin’s (1997) three levels of AM (namely, environmental activity analysis (EAA), environmental activity cost analysis (EACA), and environmental activity-based costing (EABC)). The study also examines the association between EAM and environmental performance, and the role of decision quality as a mediator in this relationship. Design/methodology/approach Data were collected from 208 Australian organisations across different industries using a mail survey questionnaire. Findings The results indicate a relatively high extent of EAA use but a low extent of use of EACA and EABC. In addition, organisations using each level of EAM to a greater extent were found to experience higher levels of environmental performance. Furthermore, the relationship between EAA and EABC with environmental performance was found to be mediated by decision quality. Practical implications The findings suggest that organisations should endeavour to increase their use of EAM, and modify their existing costing systems to consider the drivers and costs of environmental activities. Originality/value This is the first study to empirically examine the extent of use of EAM and its association with environmental performance.

The seaweed farmers who are competent indicated by their positive behavior on technical and management of sea weed farming. The objectives of the study are: (1) To find the sea weed farmers characteristics in relation to their competence in sea weed farming management; (2) To find evidence how they practice on sea weed farming; (3) To analyse the relationship between the sea weed farmers characteristics and their competence in sea weed farming. The study was desigred as a descriptive correlation, the data were analyzed using qualitative and quantitative methods same important results are: (1) Majority of the farmers are old age, they have enough experiences in sea weed farming, they have frequently interacted with the extension educator; (2) Most of the farmers have enough competent in: a) Selecting the seeds; b) Harvesting; c) Planting; d) Post harvest management; e) Marketing; and f) Preparation of the farming. There were high significant correlation between age, education, experiences, areal of farming, family dependent members, interaction with the extention educator, and the farmers competencies.

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.
