small precipitation with temporal and spatial variation of rainfall is the main responsible factors on flood occurrence in arid and semi arid regions. floods in their regions usually contain high concentration of sediments which when they are deposited on the surface of lands, they change the properties of soils of the area. in this research, the effect of floodwater spreading on physic-chemica...

introduction today, with the increasing population and the need for strategic and industrial crops the farmers are simulated to grow these kinds of crops. thus, this subject has now been caused the inappropriate use of land and natural resources. on the other hand, the natural environment resources have limited the ability to use its resources and the climate change intensifies this limit abili...

in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...

application of various composts has been intensified in agriculture, due to manifestation of negative effects of chemical fertilizers on environment and soil fertility. however, their usage should be accompanied by environmental and nutritional studies. to study the effects of sulfur granular compost on yield and yield components of two wheat cultivars, a pot experiment was conducted in a compl...

effects of different paclobutrazol concentrations (0, 250, 350 and 450 mgl-1) and plantlet density (80, 100 and 120 plantlet/m2) on minituber production per plantlet in potato cultivar ‘sante’ were investigated in a factorial experiment based upon a randomized complete block design of 4 replications. paclobutrazol (cultar with 250 g/l of active ingredient) was used as foliar application at earl...
