in order to understand the effect of plant density and different fertilizers on sesame (sesamum indicum l.) production, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were fertilizers in four levels (cow manure (30 t.ha-1), municipal compost (30 t.ha-1), chemical fertilizer (250 kg ammonium ...

a field experiment was conducted in 2010, to evaluate the effects of plant density (d1, d2 and d3: 8, 14 and 20 plant/m2) on field performance of sorghum under different nitrogen application rates (n1, n2 and n3: application of 40, 80 and 120 kg/ha nitrogen, respectively). the experiment was arranged as factorial based on randomized complete block design in three replicates. results indicated t...

This paper tries to determine an optimum condition for the flotation operation of the Alborz-Sharghi coal washing plant. For this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. Four operational variables such as the collector dosage (Fuel oil), the frother dosages (MIBC), the pulp density percent and t...

in order to study the intercropping of barley (hordeum vulgare l.) and faba bean (vicia faba l.) an experiment was conducted as factorial based on randomized complete block design with two factors and three replications at sari agricultural science and natural resources university during 2009. the first factor was two seed ratios include d1: 75 and 150 kg.ha-1 of faba bean and barley, respectiv...

beet necrotic yellow vein virus (bnyvv) or rhizomania is one of the most important and destructive diseases of sugar beet (beta vulgaris l.) in the world. this disease is considered as a limiting factor of sugar beet production in iran such as khorasan, fars, west azerbaijan, isfahan and kermanshah. in order to develop of resistant variety, as simple and easy methods for disease control, a germ...
