Abstract

In order to evolution of radiation use efficiency (RUE) of sesame in the condition of using biological and chemical fertilizers and calculation of light extinction coefficient (K), an experiment was conducted in the year 2013 in RCBD design with 3 replications and 10 treatments. Treatments included biological fertilizers of nitroxin, Biophosphor, biosulfur, the mixture of nitroxin-Biophosphor (Ni+BP), the mixture of nitroxin-Biophosphor-biosulfur (Ni+BP+TB) and chemical fertilizers of Urea, Triple superphosphate, the mixture of Urea-Triple superphosphate (U+P), the mixture of Urea-Triple superphosphate-Sulfur (U+P+S) and Control. Results showed that light extinction coefficient of 0. 7 was an acceptable value. Biological and chemical fertilizers increased leaf area index (lai) and RUE of Sesame and generally, chemical fertilizers increased RUE more in comparison of biological fertilizers. The highest value of lai (3. 42 and 3. 32) belonged to U+P+S and U+P. RUE values in mixture treatments of biological and chemical fertilizers especially for Ni+BP+TB and U+P+S (1. 34 and 1. 41 respectively) were greater than its values in the sole application of fertilizers. Urea increased radiation use efficiency of sesame (1. 34) more than nitroxin (1. 14), while the amount of increase of radiation use efficiency in triple superphosphate (1. 26) and Biophosphor (1. 25) was almost identical. Therefore, it is recommended that fertilization of sesame be done by using the mixture of some different biological or chemical fertilizers in order to maximizing RUE by compliment of plant nutritional needs.
