AGRONOMIC PERFORMANCE OF SUNFLOWER AS INFLUENCED BY SULPHUR NUTRITION AND SULPHUR OXIDISING MICROORGANISMS
Journal Title: International Journal of Microbiology Research - Year 2017, Vol 9, Issue 1
Abstract
Field experiment was conducted during kharif 2014 at STCR Farm, M.P.K.V., Rahuri (Maharashtra). Twenty treatment combinations consists of four levels of sulphur (0, 15, 30 and 45 kg S ha-1 respectively) and five sulphur oxidizing microorganisms (Thiobacillus thiooxidans, Thiobacillus ferroxidans, Aspergillus awamori, Aspergillus niger and consortium respectively) were laid out in Factorial randomized block design with three replications. The sulphur application @ 45 kg ha-1 to kharif sunflower significantly increased seed and oil yield (19.89 q ha-1 and 812.48 kg ha-1).The yield contributing characters of sunflower viz., number of leaves, leaf area, plant height, head diameter, number of filled, unfilled and total grain per capitulum were significantly influenced by the 45 kg ha-1 sulphur application. Thiobacillus ferroxidans sulphur oxidising microorganism was found beneficial for all the yield attributing characters except number of unfilled grains per capitulum. The interaction effects were significant.
