Öğe THE RESPONSE OF COTTON (GOSSYPIUM HIRSUTUM L.) TO SOIL APPLIED ELEMENTAL SULPHUR UNDER BORON TOXICITY(Parlar Scientific Publications (P S P), 2016) Kurt, Firat; GultekinTemiz, MefharThis study was conducted between 2013 and 2014 to determine the effect of sulphur fertilization on boron toxicity in cotton. Two sulphur doses (0-1 that) as main plots and four boron doses (0, 2.5 ppm, 5 ppm and15 ppm) as subplots were arranged in randomized complete split block design. According to the results, despite lack of phytotoxic symptoms of B, 5 mg B kg(-1), B treatment showed significant effects on seed cotton yield, gin turnout, fiber maturity, and fiber elongation. However, the influence of B was uneven and inconsistent between years and among B dosages. Therefore, it could be concluded that higher doses of B applications should be avoided for higher lint yield and fiber qualities. In terms of S application, the amount of S dose employed in this study significantly decreased seed cotton yield and gin turnout; however, it had no effect on other lint quality parameters. This result may be of particular importance to the cotton growing soils with higher pH, which is required in applying higher doses of sulphur for optimum yields.
