Response of paddy to different sources and levels of sulphur and their effect on soil properties in southern dry zone of Karnataka

摘要

A field experiment was carried out at ZARS, Mandya, Karnataka during kharif season of 2005-06 to study the effect of different sources and levels of sulphur application on growth and yield of paddy and on properties of soil. The results revealed that application of bentonite and SSP at the rate of 60 kg S/ha recorded the higher growth, yield attributes and crop yield. The performance of SSP and bentonite were on par with each other and were significantly superior to gypsum. Soil properties did not differ significantly due to different sources of sulphur. Bentonite treated plots recorded maximum available sulphur followed by SSP and gypsum.
