Determination of Soil Conservation Effects on Shadow Price of Soil Quality in Dry-Farmed Wheat in Iran (A Case Study)

Pakistan Journal of Biological Sciences (2008)

Seyed Saeid Hosseini Mohammad Ghorbani M. Ghahremanz

This study attempts to measure the effects of soil conservation practices on soil quality in dry-farmed wheat in Iran (Zanjan province) using a bio-economic production function. Because of the nature of data (panel data) and information used in this study, error components approach (REM method) was used for estimating the production functions. The results indicate that the shadow price increases with soil depth and its magnitude is greater 72% in average--in conserved soils compared to non-conserved ones. In fact the results support the effectiveness of soil conservation in improving physical, chemical and biochemical properties of soil which contributes to sustainable agriculture. Finally, soil conservation benefits were estimated to be about 29.98 dollar pre hectare. That may be use for extension, payment of green subsidy, investment and adoption of new technologies for soil conservation. In this way, it will increase the real value of farm and farmer's welfare.

Biodegradable kefiran-chitosan-nanocellulose blend film: Production and physical, barrier, mechanical, thermal, and structural properties

Hanie Salmanian Faramarz Khodaiyan Seyed Saeid Hosseini

In this study, biodegradable kefiran-chitosan-nanocellulose blend films were developed and their physical, mechanical, barrier, thermal and structural properties determined. Results showed that adding nanocellulose had not any significant effect on the thickness, moisture content and water solubility. Also, water vapor permeability, tensile strength and lightness increased and the elongation at break, glass transition and melting temperatures, chromaticity parameters of red–green and yellow–blue, total color difference, and whiteness index decreased by increasing the nanocellulose content. Scanning electron microscopy demonstrated that at high concentrations of nanocellulose, the nanoparticle dispersion was not uniform and many agglomerations observed in the surface and cross-section of the nanocomposites. In the end, XRD analysis showed that the dispersed phase of nanocellulose could not indicate its own crystalline peaks in the kefiran-chitosan matrix.

Production, optimization and characterization of pullulan from sesame seed oil cake as a new substrate by Aureobasidium pullulans

Carbohydrate Polymer Technologies and Applications (2020)

Homaira Mirzaee Faramarz Khodaiyan John F. Kennedy Seyed Saeid Hosseini

Sesame seed oil cake (SSOC) was applied as a novel substrate for production of high-added value pullulan by Aureobasidium pullulans KY767024 (a melanin-deficient strain). The optimization of production conditions by central composite design showed that the maximum production yield (54.50 g pullulan/kg substrate) was obtained under optimum conditions (Liquid-solid ratio (LSR) of 1.7 v/w, inoculum size of 7 mL, and temperature of 23 °C), which was confirmed by the experimental data (52.50 ± 0.73 g/kg). The obtained pullulan had an average-molecular weight of 358.736 kDa. The present peaks in the FT-IR spectrum validated that the obtained purified precipitate was composed of pullulan. Also, the XRD pattern and TGA analysis showed that the produced pullulan had a fully amorphous structure with high thermal stability. In addition, the pullulan solutions had a different flow behavior in different concentrations and with an increase in concentration, their behavior changed from Newtonian to pseudoplastic.

A Methodological Aggregation-consistent Individual Level Supply Response Model

Journal of Agricultural Science and Technology (2009)

Seyed Saeid Hosseini John Spriggs

Government interventions in agricultural markets in order to stabilize commodity prices and producer incomes have had a long tradition. Intervention has been at both the state and country levels and has been for the most part in the form of commodity-based schemes. This study represents an attempt to develop an appropriate methodology for analyzing the aggregate effects of a particular type of policy rule. This type of policy rule is one for which the unit of observation is the individual farm unit rather than the individual unit of commodity. The methodology developed in this paper represents an initial attempt to provide the necessary micro-macro modeling with supply response which is required for analyzing the aggregate effects of whole-farm income support programs. The methodology will be illustrated by an empirical application of the aggregate impacts of the whole-farm program in Saskatchewan, Canada.

STUDY OF MARKET POWER IN IRANIAN RED MEAT MARKETING CHAIN

Seyed Saeid Hosseini A Abbasifar H A Shahbazi

Abstract Identification of price determination conduct in agriculture commodities market is an important problem in marketing process because market structure and conduct conditions (competitive or noncompetitive) can affect produced agriculture commodity, and thereby can affect surpluses of different groups of society. Utilizing monthly data for 1998-2005, marketing margin model of beef and lamb are estimated and then market power in farm and retail levels are evaluated. Results imply that there is competitiveness in farm and retail levels of beef and lamb. JEL Classification: D41, D43
