Abstract

In order to study the effect of sulfur and Thiobacillus on some qualitative and quantitative traits of sunflower (cv. Hisun 25), an experiment was conducted as factorial based on Randomized Complete Block Design with three replications on research farm of the Gonbad Kavous University in 2013. The sulfur rate factor was in four levels: 0, 200, 400 and 600 kg sulfur per hectare and Thiobacillus bacteria factor was in four levels: 0, 10, 20 and 30 kg Thiobacillus per hectare. Results showed that the sulfur had a significant effect on plant height, 1000-seed weight and seed yield at 5% and on plant dry weight, oil percentage and oil yield at 1% probability. Effect of Thiobacillus on 1000-seed weight and seed yield at 5% and on plant height, plant dry weight, oil percentage and oil yield at 1% was significant. The maximum values of all traits were obtained from the highest amounts of sulfur and Thiobacillus. The highest plant height, 1000-seed weight, plant dry weight, seed yield, oil percentage and oil yield obtained from consumption of 600 kg S/ha. The maximum plant height, 1000-seed weight, plant dry weight, seed yield, oil percentage and oil yield belonged to consumption of 30 kg Thiobacillus/ha. The results of this study showed that effect of sulfur and Thiobacillus on some morphological traits, seed yield and yield components was less than percentage and yield of oil. This maybe has happened because of the sulfur role in oil production.

Abstract

In order to study the effects of different levels of sulfur along with Thiobacillus and zinc on qualitative and quantitative growth of canola cv RGS003, a factorial experiment was conducted based on an RCBD with three replications at the Agricultural Research Station of Gonbad in 2013. The first factor was the application of sulfur with Thiobacillus at four levels, i.e. without sulfur and Thiobacillus (S0), 500 kg sulfur ha-1 + 10 kg Thiobacillus ha-1 (S1), 1000 kg sulfur ha-1 + 20 kg Thiobacillus ha-1 (S2) and 2000 kg sulfur ha-1 + 40 kg Thiobacillus ha-1 (S2). The second factor consisted of two levels of zinc: without zinc (control) and 20 kg zinc sulfate ha-1. The results showed that all traits studied were significantly affected by sulfur with the exception of pod length. The effect of zinc was significant at 0.01 probability level of biological yield, seed yield, harvest index, straw yield, oil percent and oil yield. With an increase in application of sulfur mixed with Thiobacillus up to 1000 kg sulfur ha-1 + 20 kg Thiobacillus ha-1 (S2), all yield components increased except oil percent, but their further increase resulted in reduction of seed yield and yield components of canola cv RGS003. With the exception of oil content, the other traits studied were not affected by the interaction of sulfur by zinc.
