in order to determine radiation use efficiency and phenological and physiological characteristics of three maize hybrids on seven plant densities, an experiment was conducted during 2006 growing season in mashhad, iran. three maize hybrids including late-rippening maize (704), medium-rippening (504) and early-rippening maize (260) and seven plant densities including d1=3, d2=5, d3=7, d4=9, d5=1...

as compared to ksc 704 hybrid with 9.844 t/ha, the maize hybrid, ksc 705(k3640/3 × mo17) produced an average grain yield of 11.120 t/ha over seven locations evaluated in final trials for two consecutive years (2007-8). in advanced yield trials done in 2011, across seven locations, this hybrid performed the highest grain yield, 10.450 t/ha, while ksc 704 produced 8.513 t/ha. in addition to the g...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

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...
