Journal Title: Scientific Journal of Pure and Applied Sciences - Year 2014, Vol 3, Issue 6
Abstract
In order to investigate the effects of zinc, boron and sulfur on yield, yield components and comparisom oil and protein in rapeseed var. Hyola 401, an experiment was conducted in Iran, markazi province in 2011. A field experiment with completely randomized block design was performed with eight treatments in three replicates. Treatment consisted control, Zn, B, S, Zn+S, Zn+B, B+S and S+B+Zn. Sulfur treatment was added at the rate 150 kg ha-1 before sowing, and Boron was added as H3BO3 at the rate of 9 kg ha−1, ZnSO4·7H2O at the rate 25 kg ha−1 were foliar applied to the solution equally at three growth stages (three leaves, beginning stem elongation and when first flowers open) of rapeseed. Results showed that there were significant differences among treatments on given traits, grain yield, oil yield, plant height, thousand-grain weight, biological yield. Higher grain yield (1936,05 kg ha-1), oil yield (740,6 kg ha-1), thousand-grain weight (4,3 gr) and biological yield (9835,5 kg ha-1) were obtained from S+B+Zn treatment. Maximum plant height (109,8 cm) was obtained from S+B treatment. So this research showed that application of B, S and Zn fertilizers with basal fertilizer can help to increase quantitative and qualitative yield in rapeseed.
