Response of Three Wheat (Triticum aestivum L.) Genotypes to Flawheat Biofertilizer and Sulfur in Mazandaran Province

To evaluate the effect of biofertilizer and sulfur on yield and morphophysiological traits of three wheat genotypes. A split plot factorial design experiment based on completely randomized block design with four replications was performed at Gharakhail and Baykola research stations of Mazandaran province in 2014-2015. The wheat genotypes were Gonbad, Ehsan and Tirgan; the sulfur treatments consisted of levels of zero, 250 and 500 kg.ha-1 (along with Tiobacillu ssp < /em>) and biofertilizer of zero and two l.ha-1 (via treating seeds). The traits studied were plant height, leaf area index, number of fertile spikes, seed yield, plant fresh and dry weights, and protein percentage of seeds. Results showed that Flawheat biofertilizer had significant effect on leaf area index, plant dry weight, number of fertile spike and seed yied, and application of two liters of biofertilizer improved the traits under study. The highest plant height (117.7 cm) was observed in Tirgan cultivar by using 2 kg.ha-1 of flawheat biofertilizer and 250 kg.ha-1 of sulfur. In all three cultivars of Gonbad, Ehsan and Tirgan, consumption of 2 l.ha-1 of flawheat and 250 kg.ha-1 of sulfur increased wheat dry weight compared to the control. Tirgan cultivar with 5298 kg.ha-1 produced highest seed yield by using two liters of Flawheat and 250 kg of sulfur per hectare. Based on the results obtained, it can be concluded that Tirgan among the three cultivars studied in the central and eastern regions of Mazandaran province, produced higest seed yield by using of 250 kg.ha-1 of sulfur and the application of two liters per hectare of Flawheat.
