European agriculture suffers from a substantial deficit of protein sources forlivestock and the projected changes in agro-climatic conditions in Central Europeinclude a higher risk of drought. To address these challenges, the drought resistantlegume crop chickpea was compared with pea, barley and oat regarding its nitrogen(N) yield, protein yield and N use and utilization efficiency under Centr...

background & aim: milk thistle [silybum marianum (l.) gaertn] is an annual or biennial plant, native to the mediterranean area, which has spread in north and south of iran. a fruit of milk thistle contains a relatively high amount (approx. 20%) of oil, which exhibits wound-healing, anti-burn, and hepatoprotective properties. experimental: in this research, a pot experiment was conducted usi...

in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...

background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...

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...

a significant portion of manganese (mn) chemical fertilizers applied to calcareous soils is not absorbed by the first crop and may, therefore, affect the growth as well as chemical composition of the subsequent crops, this being called the residual effect of mn, soil tests may be employed to predict such effects. the present experiment was conducted to study the residual effects of manganese su...
