Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

Abstract Rice productivity in the tropics largely depends on fertilizers as soils are commonly low nitrogen and phosphorus. Some farmers this region cultivate rice using hand-broadcast method, which has resulted a yield. Therefore, on-farm experiment was conducted to compare performance yield of broadcasted transplanted production systems under different fertilizer combinations. The experimenta...

The study evaluated the performances of Telfairia occidentalis Hooker fil. under varying growth media subject to amount Urea granules (25 g, 50 75 100 125 g and 150 g) dissolved in water containing micronutrients. were M25U, M50U, M75U, M100U, M125U, M150U, Control. Two-week old seedlings T. raised using River-sand transferred into non-circulatory media. indices (vine main length (VML), number ...

Plant growth regulators, especially those applied directly to the root system, are thought to significantly reduce growth of the root systems. Various perennials were treated with uniconazole (Concise, Fine Americas, Inc.) to evaluate effects on plant height as well as shoot and root dry weights. Plant height of Lobelia cardinalis was not affected by a 1 ppm uniconazole liner dip, but shoot dry...

Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...

root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...
