Drought is one of the major factors limiting crop production in Iran. Twenty Iranian wheat cultivars with wide range of sensitivity to drought, including 18 varieties of bread wheat and two varieties of durum wheat were used in two separate field experiments in 2009-2010 at the Experimental Station of College of Agricultural in Shiraz University. Each experiment was conducted as a randomized co...
drought stress is one of the most important factors limiting the productivity of crop plants around the world. genotype-by environment (g×e) interactions are common under drought and make breeding progress difficult. for this reason twenty genotypes of bread wheat were evaluated in a randomized complete block design with 3 replications at 2 locations (stress and non-stress environments) in two ...
Organic wastes, such as fats, oils, and grease (FOG), are good substrates for biogas production because of their high methane yield potential. FOG are hydrolyzed to glycerol and long-chain fatty acids(LCFA), and the degradation of LCFA takes place through the β-oxidation pathway which has been reported as the rate-limiting step of the whole anaerobic digestion process. This paper reviews the sc...
The variation in composition and daily yield of milk is a regular phenomenon in all milking animals. Broadly, the factors which are responsible for such variations can be divided into (1) Physiological, which will be governed by the genetical make up and (2) Environmental, such as age, number of previous lactations, pregnancy, nutrition status, etc. The dairyman has hardly got any control over ...
We demonstrate both theoretically and experimentally two limiting factors in cooling electrons using biased tunnel junctions to extract heat from a normal metal into a superconductor. First, when the injection rate of electrons exceeds the internal relaxation rate in the metal to be cooled, the electrons do not obey the Fermi-Dirac distribution, and the concept of temperature cannot be applied ...
Because of limiting water resources and increasing demand for food, it is necessary to investigate the effect of irrigation systems on water productivity. This research was conducted to evaluate yield and yield characteristics of two potato varieties under sprinkler and trickle irrigation systems. The treatments were two irrigation systems (sprinkler and trickle irrigation) and two potato varie...
Aprevious chapter addressed the general procedure for conducting a laboratory milling analysis and factors that impact the measure ment of milling yield, specifically milled rice yield (MRY) and head rice yield (HRY). These factors include the rice sample moisture content, temperature and milling ease, as well as laboratory mill settings and the duration for which the rice is milled. The impac...
