The effects of biological fertilizers on growth indices, yield and yield components of sesame cultivars (Sesamum indicum L.)

In order to evaluate the effect of biological fertilizers on the yield and yield components of three sesame cultivars (Sesamum indicum L.) an experiment conducted in the 2010-2011 in the form of split plots with randomized complete block design with three replications. Three cultivars of Sesam (Kalat, Esfarayen and oltan) allocated to the main plot and three biological fertilizers (nitroxin (A), phosphate solubizing bacteria (B), A+B and control) allocated to sub plot. Parameters such as SPAD readings, Leaf Area Index (LAI), Crop Growth Rate (CGR), Net Assimilate Rate (NAR), biological and economic yield, Oil content and yield, plant high, number of auxiliary branches, number of pods per plant, number of seeds per pod and 1000 seed weight were measured. Most of these parameters were not affected by the fertilizer treatments. However, there were significant differences between varieties. nitroxin+biophosphor measured plant height observed with nitroxin application. In this experiment, sesame did not respond to biological fertilizers properly and this seems to be associated with the nature of this plant and the fertilizer soil conditions and the status of biological.
