Effect of sulphur application on soil improvemet and wheat production

Abstract: A field experiment was carried out on winter season 2012/ 2013 with wheat (Bani swif 1) grown on a clayey soil at Sids Agric. Res. Station to study the effect of sulphur (S) application and micronutrients (Mi) i.e. Fe, Zn, Mn and Cu on some properties of soil and available macronutrients in soil as well as the grain and straw yields of wheat and they chemical composition. Sulphur was added at rates of 0, 250, 500 and 1000 kg /fed alone or with afore named micronutrients which sprayed at the rate of 0.1 % Fe in the form of chelated (6%), 0.05 % Zn in the form of chelated (14 %), 0.05 % Mn in the form of chelated (13 %) and CuSO4 at rate of 1 g / L. The experiment was conducted in a randomized complete block design with 4 replicates.
The obtained results showed that the values of soil moisture retention (field capacity, wilting point and available water) were increased with increasing sulphur addition. The available contents of NPK in soil were increased with S application alone , and these increases were more pronounced when micronutrients were added. The highest treatment was found to be a mixture of 1000 kg S + Mi. This treatment reflected its positive effect on the grain and straw yields of wheat, where the highest increasing percent in the grain and straw yields of wheat reached 15.02 and 20.80 %, respectively. Data also indicated that addition of S with Mi to the studied clayey soil markedly increased the contents of NPK in wheat grains and straw, particularly at the highest rate of sulphur and Mi.
On the other hand, application of S at rate of 500 kg /fed beside sprayed with Mi gave the best treatment for all the previous parameters, because there no big differenc between 1000 kg S /fed + Mi and 500 kg S /fed + Mi or not significant
