چکیده

The present study was aimed to elucidate the effect of elemental Sulphur timing and application rates on soil Ca release, Ca concentration in maize and its relationship with maize performance. After 0, 20 and 40 days of soil incubation with different amounts of elemental Sulphur including 0, 0.5, 1 and 2 g S kg-1 of soil, maize plants were grown for 45 days under glasshouse conditions. The experiment was laid out in randomized complete block design (RCBD) with factorial arrangement and four replications. Soil samples were provided before and after maize plantation and were extracted by the un-buffered and neutral extracting solutions. The nutrients in the solution were determined by an inductively coupled plasma spectrometer. The results exhibited that soil acidification by elemental Sulphur significantly increased Ca concentration in soil solution. However, soil acidification successively decreased Ca concentration in maize root, stem and leaves and it may intensify Ca deficiency in maize plants treated with high rates of elemental sulphur. In conclusion, application of elementals Sulphur at a rate of 1g S kg-1 soil is recommended for maize production in Bintang Series high pH soils of Malaysia. In conclusion, application of elementals Sulphur at a rate of 1g S kg-1 soil is recommended for maize production in Bintang Series high pH soils of Malaysia.
