Abstract
A randomized complete block design with three replications was conducted in 2009-10 and 2010-11 growing seasons. Treatments were three different types of biofertilizers plus control, including 1-nitroxin (containing of Azotobacter sp. & Azospirillum sp.), 2- biophosphor (PSB, containing of phosphate solubilizing bacteria, Bacillus sp. & Pseudomonas sp.), 3- biosulfur (SSB, containing of Thiobacillus ssp.) and 4- control (no fertilizer). The results showed that application of biofertilizers resulted to 15 days shorter period to achieve maximum leaf area index and as a result, the maximum fraction of absorbed radiation and consequently sesame dry matter produced at the sixtieth day after emergence. Radiation use efficiency (RUE) in SSB and nitroxin was higher compared to control (1.31, 1.24 and 1.09 respectively) which resulted to highest biological and seed yield, seed oil and protein and harvest index. In this research, the total mean sesame RUE estimated of 1.19 g MJ-1 (R2=0.95).
