The new crop oil from jojoba (Simmondsia chinensis) is a skin-softener similar to sperm whale oil. In an effort to find new uses of this oil, we have converted jojoba liquid wax into two new products in mild chemical processes. Tetrahydroxyjojoba wax (THJF) is a colorless, stable, low-melting solid and jojoba ferulate, an ultra violet (UV) absorbing species by esterification of the tetrahydroxy...

We analyse output risk in Italian agriculture over the period 18701914. We use data on a set of 16 tenanted plots grouped into three farms comprising a single large estate. We estimate the degree of risk associated with each separate crop, with the portfolio of crops at the level of the plot, the farm and the estate. We highlight two particular features: the relatively high risk associated with...

A study on the physicochemical properties of Jatropha curcas seed oil for industrial applications were carried out. Physicochemical properties of J. curcas seed oil (59.32% lipids) showed high content of LA (36.70%), iodine value (104.90 mg/g) and saponification value (203.36 mg/g). The present study shows that, J. curcas seed oil is rich in oleic and linoleic acids. The J. curcas seed oil with...

This research was aimed at investigating the essential oil production, chemical composition and biological activity of a crop of pink flowered oregano (Origanum vulgare L. subsp. vulgare L.) under different spatial distribution of the plants (single and binate rows). This plant factor was shown to affect its growth, soil covering, fresh biomass, essential oil amount and composition. In particul...

The peanut is a valuable seed from the legume Arachis hypogaea, which is largely produced in India, China, and the United States for human consumption as a whole seed, extracted oil, peanut butter, or protein-enhancing ingredient. Worldwide, peanuts are mostly used to produce highquality edible oil. In the United States, the majority of the crop is consumed in whole seed form or used for peanut...

This study evaluates an integrated process for the production of platform chemicals and diesel miscible biofuels. An energy crop (Miscanthus) was treated hydrothermally to produce levulinic acid (LA). Temperatures ranging between 150 and 200 °C, sulfuric acid concentrations 1-5 wt.% and treatment times 1-12 h were applied to give different combined severity factors. Temperatures of 175 and 200 ...

A potential new alternative oilseed crop from the genus Lesquerella is being domesticated for the southwestern United States and other arid climates of the world. This crop has seed oil rich in hydroxy fatty acids used to produce a variety of industrial, cosmetic, and pharmaceutical products. Many of the industrial products are replacements for non-degradable and non-renewable petroleum-based p...

INTRODUCTION Microalgae comprise a vast group of photosynthetic, auto/heterotrophic organism which has an extraordinary potential for cultivation as energy crops. These microscopic algae use photosynthetic process similar to that of higher-developed plants. They are veritable miniature biochemical factories, capable of regulating carbon dioxide (CO ), just like terrestrial plants [1]. In additi...

The narrowing of diversity in crop species contributing to the world's food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of crop species in national food supplies worldwide. Over this period, national per capita food supplies ...

To examine the effect of crop growth enhancer bacteria on quantitative and qualitative yield of safflower, an experiment in randomized complete block design was conducted in eight levels with four replications. Bacterial factor consisted of control (absence of bacteria), AzotobacterChroococcum,AzospirillumBrazilians, Pseudomonas Fluorescens, AzotobacterChroococcum+Azospirillum Brazilians, Azoto...
