Abstract

Sulphur and sulphur oxidizing bacteria required by oilseed and pulses crop in sulphur deficient soil for maintaining soil fertility and stabilized crop production with this the present experiment was conducted on medium black calcareous soil to study the effect of sulphur sources and sulphur oxidizing bacteria (SOB) on yield, quality of summer soybean and soil nutrient status in FRBD using three replications during year 2022 at Instructional Farm, Krishigadh, Junagadh Agricultural University, Junagadh (Gujarat). The treatments consisted three sources of sulphur  (SS) viz., gypsum, elemental sulphur and cosavet (fertis) each of  20 kg ha-1 and sulphur oxidizing bacteria (SOB) viz., 0.0, 2.0, 3.0 and 4.0 lit ha-1 with three replication. The experiment consisted of twelve treatment combinations. The results indicated that yield attributes as well as seed and stover yield, oil and protein content were significantly higher with application of cosavet (fertis) and SOB @ 3 lit ha-1. The seed yield of soybean increased to the tune of 14.26 and 19.72 per cent with application of cosavet (fertis) (SS3) and SOB @ 3 lit ha-1 (SOB3) compared to treatment of elemental sulphur (SS2) and control (SOB1), respectively. The higher availability of S nutrient with application of cosavet (Fertis) and SOB @ 3 lit. ha-1 as compared to other sulphur sources and control treatment, respectively. The significantly higher sulphur oxidizing bacteria count also higher with 4.0 lit ha-1 (SOB4) as compared to control (SOB1).

Keywords: Soybean, sulphur sources, SOB, yield, quality, available nutrients status
