In order to investigate effect of nitrogen fertilizer on yield and quality of three forage sorghum cultivars under Guilan climatological conditions a field study was conducted in 2010 cropping season at Rasht. A randomized complete block design with factorial arrangement with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 50, 100 and 150 kg N ha-1 fro...

asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

In order to evaluate the effect of water stress and nitrogen levels on yield and some agronomic traits of two forage sorghum cultivars, a field experiment was conducted at the Faculty of Agriculture, Shiraz University, during Spring and Summer 2011. The experiment carried out as split-split plot based on randomized complete block design, with 3 replications. Water stress levels of 100, 75 and 5...

To evaluate forage production and land equivalent ratio (LER) in additive and replacement intercropping systems of forage sorghum and berseem clover, a field experiment was conducted using randomized complete block design with eight treatments and three replications at the research field station of Seed and Plant Improvement Institute, Karaj, Iran, in 2016-17 and 2017-18 growing seasons. The ex...

Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N...
