اثر متقابل مصرف کود با نوع خاکورزی بر میزان پنجهزنی گندم رقم مروارید

The research was conducted on Morvarid wheat cultivar in 2012-13 in split plot as a randomized complete block design in Agh Ghala region (Golestan province, Iran), were used from three levels of tillage including moldboard plow, chisel and no-till systems as main factors, and the seven levels of fertilizer compounds as sub-plots. Based on the analysis of variance, the number of infertile tillers were not affected by tillage treatments, but the number of fertile tillers were significant at the 1% level of probability. In different fertilizer treatments, fertile and infertile tillers showed a significant difference in the 1% level. No-tillage compared with tillage treatments showed lower fertile tillers, but the difference between moldboard plow and chisel were not observed. Fertilizer treatment recommended by the Buisky company with 2.79 had the highest number of fertile tillers, the treatments containing Buisky and chemical fertilizers compounds were in the next groups, common chemical fertilizers treatment was in the next class, and no-fertilizer treatment had the lowest number of fertile tillers. Overall, the tillage treatments were produced more fertile tillers than no-till system, use of fertilizers gave rise to further fertile tillers than the no-fertilizer treatment, and between different fertilizer treatments, the Buisky fertilizers significantly were effective in increasing the number of fertile tillers.
