water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...

this study aimed to analyze and modeling of energy and performance of dryland chickpea adaptive neuro-fuzzy inference system utilizes (anfis) in dryland chickpea production is done in the city of bukan. data were collected from 70 producers of chickpeas using face to face interviews with farmers and completing the questionnaire specialized. size of land was between 2 and 10 hectares. input fact...

salinity problem is continuously increasing in the arid and semi-arid regions of iran. to effectively utilize germplasm resources in breeding, it is necessary to characterize and evaluate genotypes for the desirable traits and as well for salinity tolerance. salinity tolerance of 80 wheat landraces from different parts of iran was studied in two steps. at first, the degree of salnity tolerance ...

The main results derived from the ozone pre-treatment of grain straw are shown. The use of ozone reduced acid insoluble lignin content in grain straw, whereas acid soluble lignin increased. This fact resulted in a more accessible structure to enzymes leading to higher enzymatic hydrolysis yield. Ozone consumption after 2.5 h reaction time was about 0.10-0.12 g/g DS, independently of the type of...

A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...

A green house field experiment of rice (Oryza sativa L) with arsenic amended irrigation water was conducted at Institute of Environmental Science of Rajshahi University to observe the trend of arsenic (As) accumulation into rice and soil. Sodium arsenate (Na2HAsO4) amended irrigation water (0.0, 0.1, 0.5, 1.0, 2.0 and 4.0 mg/l As) was used for cultivating a popular HYV-aman rice variety named B...

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...
