introduction the lentil or masoor (lens culinaris l.) is a brushy annual plant of the legume family, grown for its lens-shaped seeds. lentil has been one of the first crops domesticated in the near east. with 26% protein, lentil is the vegetable with the highest level of protein other than soybeans, and it is an important part of people’s diet in many parts of the world. it is reported that the...

In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...

in order to study the effect of intercropping (mix cropping) of three sesame genotypes (sabzevar, kashmar and kalat) a field experiment was conducted based on a complete randomized block design with three replications at research station, college of agriculture ferdowsi university of mashhad, in year 2009. the experimental treatments were: sole cultivation of sabzevar, kalat, kashmar genotypes,...

the adequacy of the swat model in the estimation of runoff, sediment yield and nitrate loss in the gorganrood watershed was tested, using the existing spatial database as the primary data. the model was then executed for a 31-years’ time period. in combination with the swat model, the sequential uncertainty fitting program (swat-cup and sufi-2) was added used to calibrate and validate a hydrolo...

enhancing nitrogen use efficiency is one of the most important strategies for improving productivity in agriculture and reducing risk of environmental pollutions in sustainable agriculture. in order to study the effects of different levels of organic manure and chemical fertilizer on nitrogen uptake efficiency (nupe), nitrogen utilization efficiency (nute) and nitrogen use efficiency (nue) of i...

the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...
