to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...
Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...
introduction: vermicompost is one of the important bio-fertilizer which is the product of the process of composting different organic wastes such as manures and crop residues using different earthworms. vermicomposts, especially those are derived from animal wastes,contain the large amounts of nutrients compaired with the composts prepared from crop residues. vermicomposts contain plant availab...
in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...

Rice (Oryza sativa) is a vital staple food crop in more than 60 percent of the world, and around 430 million metric tons rice are consumed worldwide. Moreover, to reduce synthetic fertilizer use while keeping production on track, researchers decided conduct study Kappaphycus drippings (K.D.) foliar at Brgy. Mangayon, Compostela, Davao de Oro from July December 2019 determine effects different r...
Nitrogen and and phosphorus are important components of plant nutrition. However inappropriate use of these nutrients can affect physiological aspects of plant. Therefore, in order to evaluate the response of some physiological parameters in purslane sucuulent plant to plant nutrition, an experiment was conducted as a RCBD with a split plot in time arrangement, which that nine levels of plant n...

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...
In Iran, fertilizers are mainly applied directly to soil. In such conditions, the yield and fertilizer use efficiency are usually low. The simultaneous application of fertilizers and irrigation water (fertigation) is an appropriate alternative to increase the efficiency of applied water and fertilizers. The objective of this study was to investigate the effect of various irrigation and fertiliz...
