| Abstract | ||
| A field experiment was conducted in an field experiment of wheat research station that located in the Al-Warka locality northeast of Al-Muthanna province during the autumn season 2014-2015 in order to study the effect of add the agricultural sulfur of different dates and levels in the degree of reaction (pH) and the electrical conductivity (EC) of a soil plant with two cultivars of wheat Triticum aestivum L., a randomized complete block design with a style of split split plot with three replicates. The results showed that the agriculture sulfur addition of the level 2000 Kg S ha-1 was a significant effect in reducing the degree of reaction and increasing the degree of electrical conductivity to the soil planted with a two cultivars of wheat IPA-99 & Abu Ghraip for the stages before planting and at harvest which were sequentially 7.14 and 7.49 for the degree of soil reaction and 3.30 and 2.96 dSm-1 for the degree of electrical conductivity, also the date added in November for the harvest stage given the lowest means for the degree of reaction and higher mean of the electrical conductivity of the soil, which were sequentially 8.02 and 2.67 dSm -1. The added dates in September gave highest mean for the degree of electrical conductivity was 3.06 dSm -1 in the stage before planting, while there was no significant effect on the degree of the electrical conductivity for the three stages. The interaction between the levels add sulfur, added dates, and cultivars a significant effect to reducing the degree of reaction for the stages before planting and at harvest. | ||
