this study was conducted to evaluate the effect of municipal waste compost leachate (mwcl) on capsicum annum plant and chemical properties of a clay loam soil with five ratios of mwcl to irrigation water (0, 20, 40, 60 and 100 percent) treatments each with three replications by using a completely randomized factorial design under greenhouse condition. electrical conductivity, organic matter...
The aim of this study was to investigate the effect of chemical fertilizers of nitrogen, phosphorus, sulfur and biofertilizer on some growth indicators of Camelina sativa L. experimental plant during the crop year 2016 in a farm located in Kazerun and as a factorial in the form of complete randomized block design with three replications. Treatments include fertile biofertilizer 2 containing pho...
This research was conducted to investigate the relationship between different traits, detecting factors affecting this relationship and to identify components of seed yield in canola under drought and normal conditions. Twenty eight canola cultivars were evaluated for morphological, agronomic and physiological traits under water stress and normal irrigation according to a randomized block desig...
Yield-loss models were developed for tobacco infected with Meloidogyne incognita grown in microplots under various irrigation regimes. The rate of relative yield loss per initial nematode density (Pi), where relative yield is a proportion of the value of the harvested leaves in uninfected plants with the same irrigation treatment, was greater under conditions of water stress or with high irriga...
drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
introduction sunflower (helianthus annuus l.) is one of the most important oil crops in the world. iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. hence, studying the effect of irrigation on ...
to investigate the relationship between different traits, discover factors affecting this relationship and to identify components of seed yield in cultivated and wild safflower genotypes, this investigation was conducted at isfahan university of technology research farm under two different water regimes during 2008. significant differences were observed between genotypes belonged to the two spe...
BACKGROUND: Nitrogen is a basic plant component, playing a decisive role in the intensification of plant production. Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. OBJECTIVES:</s...
