Abstract
An investigation was conducted on cauliflower ( L. var. Palam Uphar) at CSK Himachal Pradesh KrishiBrassica oleracea Vishvavidyalaya, Palampur to study the effect of varying levels of sulphur and its Sources on various sulphur fractions in an Acid Alfisol of Himachal Pradesh. The experiment consisted of three levels (12.5, 25, 37.5 kg S ha ) and four sources (Sartaj natural gypsum, locally -1 available gypsum, elemental sulphur and single super phosphate) of sulphur. Available, water soluble, organic form of sulphur and total sulphur increased significantly with increased levels of sulphur. Whereas, in sources Sartaj gypsum recorded maximum available sulphur (12.4 mg kg ) and water soluble (9.8 mg kg ) followed by single super phosphate, locally available gypsum and elemental sulphur. Different -1 -1 sources of sulphur did not show any significant effect on heat soluble sulphur, organic sulphur and total sulphur. All sulphur fractions were significantly and positively correlated with available form of sulphur. However, highest correlation was observed with water soluble sulphur.
