Results from long-term experimental trials suggest that similar yields and lower costs are possible from organic compared with conventional field crop production, but there is little information about the relative costs and returns on commercial farms. This study examines the structure and profitability of commercial wheat production using a nationwide survey of wheat producers for 2009 that in...
This paper investigates the effects of wheat production risk and other socio-economic factors on the probability of adopting new seed technologies. Also, the effects of production inputs and production conditions are examined on wheat production yield and risk. Moreover, the relative risk of new seed varieties will be examined under different scenarios. To carry out the study, farm-level data ...
Production of pork, the most consumed meat globally, is estimated to emit 668 m tonnes CO2-eq of greenhouse gases each year. Amongst various production systems that comprise the pig industry, grain-based intensive production is widely regarded as the largest polluter of the environment, and thus it is imperative to develop alternative systems that can provide the right balance between sustainab...
Many production activities generate undesirable byproducts in conjunction with the desirable outputs they produce. The present study uses an output distance function approach and its duality with the revenue function to estimate the marginal abatement cost of CO2 emissions from a sample of thermal plants in India. Two sets of exercises have been undertaken. The marginal abatement cost is first ...
Abstract. Adaptation to future climate change with limited water resources is a major global challenge sustainable and sufficient crop production. However, the large-scale responses of footprint its associated benchmarks under various irrigation regimes scenarios remain unclear. The present study quantified maize wheat (WF) per unit yield (m3 t−1) as well corresponding WF two Representative Con...
Background: Iran is located in the seventh rank in terms of CO2 emissions resulting from the fuel combustion in the world. Gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of CO2 and CH4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....
Emerald, north-east Queensland, is at the northern margin of the wheat cropping region of Australia. The Emerald region was previously used predominantly for grazing beef cattle; however, cropping has developed in importance over the past 30 years. We use historical climate records (1890-1998) to simulate and compare wheat yields, grass production and live-weight gain (LWG) over time. The cropp...
Cellulose is the most plentiful renewable biopolymer in nature which could be utilized by cellulolytic enzymes. Cellulases are among the most important groups of industrial enzymes which are widely consumed in biofuel production, pulp and paper, textile, and detergent industries. These enzymes can support a cleaner environment through reducing chemical processes in mentioned industries and agro...
Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
