Available sulphur status of rice growing regions of Mandya district, Karnataka

Abstract

A study was conducted with a view to assess the soil available sulphur status of rice growing regions of Mandya district. A total of 119 soil samples were collected manually randomly from 0-15cm depth Hobli wise, (4-5 samples/hobli) from seven taluks of Mandya district. The soil samples were analyzed and it is observed that out of 119 soil samples about 92 samples were found to be sufficient and 27 samples were deficient in available sulphur content. As per the statistical analysis 77.32 % and 22.68 % of the samples of the study area are sufficient and deficient in available sulphur content. The overall results portray that in different taluks of Mandya district, four taluks i.e Mandya, Maddur, S.R. Patna, and Pandavapura have recorded sufficient range of sulphur status, where as in other taluks namely Malvalli, K.R. Pet, and Nagamangala taluks with deficient sulphur status were observed. Nagamangala taluk has least sulphur status among taluks of Mandya district with all five hoblis showing deficiency range of sulphur status: barring Nagamangala taluka, the remaining taluks are sufficient in available sulphur hence an intelligent application of sulphur fertilizers and organic manures are right away recommended.
