management of chemical fertilizers application is very important issues on environment and plant yield especially in arid and-semi arid region. in order to determine the effects of drought stresses and fertilizer levels on quantity and quality yields of psyllium (plantago ovata l.), a study was conducted as split plot based on randomized complete block design with four replications at the natur...

in order to study the effect of different levels of the manure and foliar application of zn and mn fertilizers on the quantitative and qualitative yield of soybeans (var. williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two levels of mn...

In order to investigate effect of application of Nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of Randomized Complete Block Design with four replications was conducted. Four levels of Nitrogen fertilizer (N1: 100% chemical fertilizer, N2: 75% chemical fertilizer + 100% biological fertilizer, N3: 50% chemical fertilizer + 100% biologi...

in order to evaluate the effects of drought stress and plant density on yield, yield components and morphological characters of pinto bean (phaseolus vulgaris l.) c.o.s16 cultivar, a field experiment was conducted in split plot arrangement based on a randomized complete block design with three replications in research field of yasouj university during 2010. experimental treatments were pinto be...
