Different winter barley cultivars showed various levels of genetic tolerance when they were exposed to different stress conditions. Therefore, investigations of interaction among genotypes (cultivars) and environments give useful information concerning yield stability and quality in barley (Blum, 1989; Ceccarelli et al., 1998, 2000; Lalić et al., 2007, 2009). Drought conditions frequently give ...

Using an integrated assessment approach, we evaluate the impact that surface O3 in East Asia had on agricultural production in 1990 and is projected to have in 2020. We also examine the effect that emission controls and the enforcement of environmental standards could have in increasing grain production in China. We find that given projected increases in O3 concentrations in the region, East As...

in order to evaluation of the process of genetic improvement rate and duration of grain filling among wheat cultivars, the field experiments were conducted at the agricultural and natural resource research center of golestan province in the growing seasons of 2007-2008 and 2008-2009. the 16 cultivars were sown in a randomized complete blocks design with three replications. the results showed th...

It is very necessary to research the fluctuation of agricultural products prices as well as the data character. In this paper, the wholesale price of agricultural product is considered. The monofractal analysis and multifractal analysis methods are introduced to study wholesale price. We select the appropriate algorithm to calculate the fractal characteristics of the celery wholesale price. Res...

Bean constitutes, with rice, the staple diet of the Brazilian people. The quality control of beans includes computing the percentages of different varieties present in a batch of beans. The selling price of the batch depends on these percentages. In this work, we propose a computer system for visual inspection of beans. We use “correlation-based multi-shape granulometry” for the first time to s...

BACKGROUND Aflatoxins are a metabolite of Aspergillus molds and are widespread in the natural environment. Workers who handle food grains are at increased risk of exposure to aflatoxins and subsequently certain respiratory conditions. In India, more than half of the employed population is engaged in some type of agricultural work, yet little known about the respiratory problems as a result of e...

Since no comparative advantage analysis system developed for agricultural products in China counties, this paper discussed how to use comparative advantage theory and Java language to design regional main grain comparative advantage analysis system. The system applies comparative advantage index calculation method to rapidly provide users with relevant data and analysis of grain production comp...

Stored-product insects can cause postharvest losses, estimated from up to 9% in developed countries to 20% or more in developing countries. There is much interest in alternatives to conventional insecticides for controlling stored-product insects because of insecticide loss due to regulatory action and insect resistance, and because of increasing consumer demand for product that is free of inse...

As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have b...

karim as a new line (hamam-4: t.aest/sprw's'//ca8055/3/bacanora86 icw92-0477-1ap-1ap-4ap-1ap-0ap) was evaluated at gachsaran agricultural research station in 2004-2005. it was selected for its high grain yield (3975 kg ha-1) and included in advance yield trial in gachsaran, khoramabad, gonbad, moghan and ilam field stations in next growing season. average yield of this line and check ...
