this study planed to determine appropriate planting date and proportion of alfalfa and barley in mixed cropping. experiment carried out in khair abad station of agricultural and natural resources research center of zanjan for five years (2004-2007), using split plot design which main plot was planting date (aug .15, sep.26 and oct .6) and subplot contain alfalfa to barley ratio, barley, alfalfa...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
introduction bean (vicia faba l.) has the great old history of crop cultivation to date would be pushed back to a fairly long day plant, resistant to frost and cool season crop and up to 5 degrees celsius tolerated. bean prefers wet and cold conditions. excessive heat may cause fetal growth problems, loss and reduce the number of seeds per pod bean flowers to the growth of plant and fruit set o...
Preplant nitrogen (N) application, which involves placing nutrients in the soil before seeding, has been an integral part of crop production systems for decades. Some producers are known to apply N at least 21 d planting. This may increase loss and lower grain yield. study evaluated effect timing rate application on winter wheat (Triticum aestivum L.) yield use efficiency (NUE). An experiment w...
Camelina is one of the plants that it seed yield is highly dependent on planting date. This experiment was conducted using randomized complete blocks design with three replications in research farm of Fasa Branch, Islamic Azad University, Fasa, Iran in 2018 and 2019 cropping seasons. Planting dates at six levels; November 1, 11, 21 (autumn sowing) and February 20, March 1 and 11 (winter sowing)...
Production of halophytes using saline waters and soils, and feeding livestock with them, is one of the most sustainable ways of desert ecosystems conservation and food production for people living in these areas. A field experiment was conducted at Salinity Research Station, Ferdowsi University of Mashhad, in 2007 to evaluate the effect of planting density and harvesting time on oil and protein...
Cereal and legume intercropping could improve cereal yield, but the role of in grain quality still lacks a full understanding. A two-year bi-factorial trial was conducted to investigate two planting patterns (mono-cropped wheat (MW) intercropped wheat+faba bean (IW)) four nitrogen (N) fertilization levels (N0, no N fertilizer applied both faba bean; N1, 90 45 kg ha–1 N2, 180 N3, 270 135 bean), ...
It is believed that various types of field bean, including pinto, white and red, differ in adaptability to high temperatures and may, thus, differ in response to delay in planting. In order to evaluate this response, an experiment was conducted during 1996 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with split-plot layout. M...
This study was conducted to determine the optimum planting date and density for a selected population of Behbahan onion for two years. Experiment was conducted as a split factorial based on RCBD design with four replications. Main plots consisted of four planting dates from 6 September to 23 October with 15 day intervals. Sub plots consisted of combinations of three row spaces (20, 30 and 40 cm...
