effects of different quantities of sulphur and boron on quantitative and qualitative yield of bread wheat cultivar pishtaz

to study the effects of different amounts of sulphur and boron fertilizers on grain yield and grain quality of bread wheat cultivar pishtaz, an experiment was conduncted in karaj during two cropping seasons 2001-2003. three levels of sulphur (s0= 0, s1=250 and s2= 500 kgha-1) and three levels of boron (b0= 0, b1= 20 and b2= 40 kgha-1) were different treatments of the experiment arranged in rcbd with three replications in factorial. analysis of variance on grain yield indicated significant differences among the treatments. the highest grain yield and grain protein percent were obtained from the treatment in which the highest levels of sulphur and boron had been used
