Abstract:

A field experiment was conducted to assess the impact of sulphur fertilisation on the yield and quality of small onion (CO (On) 5) grown in S deficient black soil (Vertic Ustropept) which was sandy loam in texture with available S content of 7 mg kg-1. Ammonium sulphate and Single super phosphate were the two sources of sulphur applied along with recommended doses of N, P and K at the levels of 0, 20 and 40 kg S ha-1 with and without VAM. The bulb yield increased significantly with the application of ammonium sulphate with recommended dose of fertilizers at the higher level of 40 kg S ha-1 (6.5 t ha-1) which was 31.07% higher over the control (4.48 t ha-1). However, application of VAM with ammonium sulphate and RDF at higher levels was also statistically on par with the same combination without VAM. The highest sulphur content (0.754%) and sulphur uptake in bulbs (19.83 kg ha-1) were higher with application of ammonium sulphate @ 40 kg S ha-1 + RDF. The quality parameters of small onion like ascorbic acid and pyruvic acid were also higher with the application of ammonium sulphate and recommended dose of fertilizers at 40 kg S ha-1.
