Abstract
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR, Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition to the control (without adding Zeolite T1), on wheat productivity within a bilateral crop rotation was followed, consisted of wheat and chickpea, and on the content of nitrogen, phosphorus and potassium in the surface layer of the soil .The research was conducted using Complete Randomized Block Design with three replicates. The results showed that the addition of zeolite to the soil led to an increase in productivity more than control amounted to 326.4 kg/ha for T2 which represents 12.57% , and to 410 kg/ha for T3 which represents 15.8%. Regarding productivity of straw, it is found that the addition of zeolite to the soil led to an increase in the amount of straw, it was 403 kg/ha for T2, which represents 10% and 538 kg/ha for T3 which represents 12 %. Also, it increased the amount of the available nitrogen and phosphorus by increasing the addition of the raw zeolite rates, and the highest value of the two indicators were reached at the level of 40 tons/ha. The statistical analysis confirmed the significant differences. As for potassium which, is able to be utilized by the plant has been increased by 10% and 17.5% with the increasing of zeolite addition at level 20 and 40 tons/ha, respectively. The highest increase in potassium was achieved at the add level 40 tons/ha.
Keywords: Natural zeolite, Wheat, Nitrogen, Phosphorus, Potassium.
