The foliar diagnosis can be considered as a useful tool to assess the nutritional status of plants. The diagnosis and recommendation integrated system (DRIS) has been developed for this purpose. In this study DRIS norms were determined for wheat plant (Triticum aestivum L.) in the Moghan region, northwest of Iran. A data bank created from nutrients concentrations of flag leaf and yield was use...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
Glauconite is a micaceous mineral that could be source of potassium. The aim of this study was evaluation of the effects of glauconitic sandstone and potential of iron relase and toxicity in case of using as a potassium fertilizer for canola plants. The plants cultivation experiments were carried out in growth chamber in sand culture with completely randomized design as factorial. The first fac...
background: qual2k is a stream water quality model and was used to evaluate the water quality of the kine-vars river and assess the response of the river to nutrient management strategies. methods: for that purpose, 7 sample stations were selected and surface water samples were collected in the winter and summer of 2012 and were analyzed for temperature, dissolved oxygen, biological oxygen dema...

Transformačné vloženie lokálnych sietí do nadradenej siete Transformačné spojenie lokálnych geodetických sietí s nadradenou sieťou (napr. ŠTS v S-JTSK) nedáva jednoznačné výsledky. V závislosti od použitých transformačných faktorov vznikajú na homologických bodoch súradnicové rozpory, ktoré treba dodatočne zohľadniť pri výpočtoch transformovaných súradníc. Jednou z najvhodnejších transformačnýc...
An experiment was conducted to select the optimum nutrient solution for growing lettuce (Lactuca sativa L.) under hydroponic conditions (open system) and Shahrekord climate, as a completely randomized design with five different nutrient solutions and three replicates, in Shahrekord University. The nutrient solutions were: 1) Research Station for Floriculture and Greenhouse Vegetables (the Nethe...
abstract pistachio ( pistacia vera l.) is an important crop in our country and has a unique position in export goods. in respect to better nut quality this research was conducted during 2005-2006. macro and micronutrients were used as foliar application to surmount soil limitations in nutrient uptake and alternate bearing control with “owhadi” cultivar in rcbd with 3 replications. the treatment...
