dc.description.abstract | Soybean, sulphur, SOB, yield, quality, nutrients content and uptake, available nutrients A field experiment entitled “Effect of sulphur sources and sulphur oxidizing bacteria (SOB) on yield, quality and nutrients uptake by summer soybean” was conducted on medium black calcareous soil at Instructional Farm, Krishigadh, Junagadh Agricultural University, Junagadh (Gujarat) during summer season of 2022. The field experiment was comprising of three sources of sulphur viz., Gypsum (SS1), Elemental sulphur (SS2) and Cosavet (fertis) (SS3) and sulphur oxidizing bacteria (SOB) viz., 0.0 lit ha-1 (SOB1), 2.0 lit ha-1 (SOB2), 3.0 lit ha-1 (SOB3) and 4.0 lit ha-1 (SOB4) in randomized block design (Factorial) repeated thrice were tested in the experiment, in respect of growth parameters, yield, yield attributes, content and uptake of nutrients like N, P, K and S at 30 DAS, 60 DAS and at harvest in stover and seed of soybean crop, status of soil available nutrients viz., N, P2O5, K2O and S at 30 DAS, 60 DAS and at harvest as well as bacterial population in soil at 30 DAS, 60 DAS and at harvest of crop. The experimental soil was medium black calcareous, clayey and slightly alkaline in reaction with pH2.5 8.2, EC2.5 0.3 dS m-1 . The soil was low in available nitrogen (230.00 kg ha-1 ), medium in available phosphorus (32.50 kg ha-1 ), medium in available potassium (280.00 kg ha-1 ) and low in available sulphur (9.55 ppm). The results revealed that growth parameters, yield, yield attributes, quality parameters and nutrients content and uptake were significantly influenced by the different sources of sulphur and sulphur oxidizing bacteria (SOB). The results of experiment indicated that plant height, number of pods per plant, dry matter yield at 30 DAS, 60 DAS and at harvest, seed and stover yield were observed maximum with application of cosavet (fertis). Similar trend also observed in case of quality parameters ABSTRACT like, protein and oil content. The nitrogen content in seed and sulphur content in seed and plant at 30 DAS, 60 DAS and at harvest, uptake of nitrogen, phosphorus, potassium and sulphur by seed and stover at 30 DAS, 60 DAS and at harvest significantly increased with application of cosavet (fertis) as a source of sulphur. The number of seeds per pod, phosphorus and potassium content in seed, nitrogen, phosphorus and potassium content in plant at 30 DAS, 60 DAS and at harvest did not influence by different sources of sulphur. The effect of sulphur sources on available nitrogen, phosphorus and potassium in soil did not produce any significance influence at 30 DAS, 60 DAS and at harvest of soybean. Availability of sulphur in soil significantly increased by application of cosavet (fertis). The application of SOB @ 3 lit ha-1 significantly increased the plant height, number of pods per plant, dry matter yield, seed and stover yield as well as protein and oil content. However, days to 50 % flowering and number of seeds per pod did not influence by SOB application. Application of SOB produced significantly favourable effect on nitrogen content in seed, sulphur content in seed and plant at 30 DAS, 60 DAS and at harvest of soybean. Significantly higher values of all these parameters were observed with application of SOB @ 3 lit ha-1 . While, SOB application did not exert any significant effect on phosphorus and potassium content in seed as well as nitrogen, phosphorus and potassium content in plant at 30 DAS, 60 DAS and at harvest of soybean crop. Application of SOB @ 3 lit ha-1 also significantly increase the uptake of nitrogen, phosphorus, potassium and sulphur by seed and stover of soybean crop. The available nitrogen, phosphorus and potassium in the soil at 30 DAS, 60 DAS and at harvest of soybean were remains unaffected under the different levels of SOB. While the available sulphur in soil at 30 DAS, 60 DAS and at harvest significantly increase with application of SOB @ 3 lit ha-1 . Application of SOB significantly increased the population of sulphur oxidizers at 30 DAS, 60 DAS and at harvest in soil, While, in case of different sources of sulphur did not produce any significant effect on population of sulphur oxidizers in soil at 30 DAS, 60 DAS and at harvest of soybean crop. The interaction effect of sulphur sources and SOB were found non-significant with respect of all growth parameters, yield, yield attributes, quality parameters, content and uptake of nutrients by plant at harvest, available N, P2O5, K2O and S at 30 DAS, 60 DAS and at harvest as well as sulphur oxidizing population in soil at 30 DAS, 60 DAS and at harvest of soybean. The quantitatively highest yield of soybean can be achieved by application of cosavest (fertis) @ 20 kg ha-1 and SOB @ 3 lit ha-1 in the medium black calcareous soils of South Saurashtra region of Gujarat. | |
