The experiment was laid out in a split-plot design, consisting of 4 rice residue and nutrientapplication treatments in potato in main plots and 4 nutrient application treatments in onion in subplots, replicated 4 times. Results showed that, growth and yield-attributing characters of potato increased significantly with the incorporation of rice residue and application of FYM. Tuber yield (34.0 t/ha) as well as nutrient uptake was significantly higher when rice residue was incorporated with 100% recommended dose of fertilizer (RDF) + 50 t/ha FYM in potato. Growth and yield attributes of onion were significantly higher with the application of 100% (RDF) + 50 t/ ha FYM along with the incorporation of rice residue in preceding potato and among the nutrient application treatments in onion, 100% RDF + 50 t/ha FYM treatment was significantly superior to rest of the treatments. Significantly higher bulb yield was also obtained under these treatments. The interaction between rice residue and nutrient-management treatments in potato and nutrient-application treatments in onion was significant for bulb yield of onion, which was significantly higher with the combination of 100% RDF + 50 t/ha FYM treatment in onion when rice residue was incorporated with 100% RDF + 50 t/ha FYM in preceding potato (35.8 t/ha) than all other treatment combinations, but it was statistically at par with the application of 100% RDF alone in onion when preceding potato received the same level of nutrients. Thus, in DSR-potato–onion cropping system, 50 t FYM/ha could be saved in onion crop when previous potato crop was supplied with 100% RDF + 50 t/ha FYM along with rice– residue incorporation without any yield reduction.\u0000","PeriodicalId":35528,"journal":{"name":"Indian Journal of Agronomy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139789857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
