Soil Solarization as an Alternative to Methyl Bromide Fumigation for Annual Strawberry Production in a Mediterranean Area

2008

This study compares the effects of soil solarization and methyl bromide fumigation on the growth and yield of strawberry plants (Fragaria xananassa Duch.) cultivated under plastic tunnel conditions. The study was conducted in a Mediterranean coastal area, in four consecutive annual production cycles in a field with no history of methyl bromide fumigation and 2-year history of strawberry production. In all 4 years, solarization was conducted for 7- to 9-week intervals from late June to early September. Cultivar Tudla frigo-plants were planted through mulch in the first week of September of each year. Average daily soil temperatures in solarized plots measured at 15 cm depth were 6.0, 8.1, 7.…

Enzymatic Hydrolysis of Lignocellulose for Bioethanol Production

2017

Abstract The effect of temperature, time and amount of enzyme on hydrolysis of wheat straw lignocellulose remaining after furfural production was studied. The residual substrate was subjected to enzymatic hydrolysis at different temperatures — 45 °C, 50 °C and 55 °C. Hydrolysis time was 72 hours, and samples were taken every 24 hours. The maximum glucose yield (76.5% of the theoretically possible) was reached when hydrolysis temperature 50 °C was used. The production rate of glucose increased with a hydrolysis period of time. The yield of glucose significantly depended on the ratio of enzyme to substrate.

Kinerja Sapi Bali Jantan yang diberikan pakan Rumput Gajah (Punnisetum purpureum) subtitusi fermentasi Jerami Padi

2018

The research was aimed to study Bali bulls fed with Pennisetum purpureum with fermented rice straws substitution in Manokwari Regency, West Papua was conducted experimentally with 12 Bali bulls that have average weight of 176.02±38.35 kg with 2 – 2,5 years old for 5 months duration. The study was designed using complete randomized design of nested pattern with 3 (three) treatments, 4 (four) replications and 4 (four) times weighing, with an assumption that Bali bulls are nested during weighing time. The results of this study showed that Penicetum purpureum substitution with fermented straws did not significant on Bali bulls body weight. The duration of fermented rice straws feeding that subs…

Reduction of Nitrates in Waste Water through the Valorization of Rice Straw: LIFE LIBERNITRATE Project

2018

An improved and more sustainable waste management system is required for successful development of technologies based on renewable sources. Rice straw is submitted to controlled combustion reactions and the produced ashes are chemically treated to produce silica. After a chemical activation step, the activated silica shows potential as an adsorbent agent and will be used to remove the excess of nitrates in groundwater and wells in the area of Alginet (Valencia, Spain), selected as a vulnerable zone within the Nitrates Directive. The demonstration activity aims to have a local impact on municipalities of 200 inhabitants or fewer, decreasing from current nitrate concentrations close to 50 mg/…

Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport

2016

Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria x ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…

Characteristics of rice straw and sewage sludge as composting materials in Valencia (Spain).

2004

This work supports the idea that composting can be useful for minimizing the rice straw and sewage sludge environmental impact. Several physical, chemical and microbiological properties of these raw materials were analyzed. The characteristics of the rice straw were complementary to those of the sewage sludge for the application of composting. The C/N ratios suitable for a rapid increased in microbial activity were the lowest (17-24). A temperature of 62 degrees C during 48 h removed pathogenic microorganisms from rice straw and sewage sludge mixture. The results obtained in the present work suggested that these materials could be use in the composting process.

Evaluation of quality parameters of strawberry fruits in modified atmosphere packaging during storage

2010

The objective of the present study is to evaluate the effect of modified atmosphere packaging (MAP) during storage on some quality parameters of strawberries. Strawberries (cv. Camarosa) were harvested when mature, forced air cooled and divided into two groups as fruits in MAP and control. After packaging, fruits were stored at 0°C, 90 - 95% RH for 10 days plus 1 day at 20°C and 50 - 55% RH for the evaluation of shelf life. Changes in fruit quality, mass loss, decay, color, firmness, total soluble solids (TSS), acidity, glucose, fructose, saccharose and color were investigated. The mass loss and decay were lower in MAP than observed in the control whereas firmness, TSS, acidity and color di…

Strawberry Variety Trial in Sicily.

2013

The Sicilian strawberry area differs from other Italian strawberry areas for its high earliness with productions that start in November-December. The earliness due to the very low plant winter chilling requirement is a very important characteristic to define the variety adaptability to this environment. Through the "Liste varietali Fragola" project funded by MiPAAF, many new varieties and advanced selections are evaluated annually in Sicily. Here, at the moment, the main variety is Florida Fortuna, followed by Candonga ® Sabrosa and Naiad ® CIVL35. Florida Fortuna, released in Florida, showed to be very interesting especially for its outstanding earliness, a high yield and good fruit qualit…

The contribution of mulches to control high soil erosion rates in vineyards in Eastern Spain

2014

Soil erosion take place in degraded ecosystem where the lack of vegetation, drought, erodible parent material and deforestation take place (Borelli et al., 2013; Haregeweyn et al., 2013; Zhao et al., 2013). Agriculture management developed new landscapes (Ore and Bruins, 2012) and use to trigger non-sustainable soil erosion rates (Zema et al., 2012). High erosion rates were measured in agriculture land (Cerdà et al., 2009), but it is also possible to develop managements that will control the soil and water losses, such as organic amendments (Marqués et al., 2005), plant cover (Marqués et al., 2007) and geotextiles (Giménez Morera et al., 2010). The most successful management to restore the …
