In the soil, P massively precipitates to form insoluble complexes with the minerals. Cereals-legumes intercropping may promote cereal growth by increasing the amount of available P and N by the legume. The legumes N₂-fixing symbiosis rely on large quantities of phosphorus as a source of energy. The aim of this study was to evaluate the impact of faba bean-rhizobia symbiosis on the growth of barley plants in intercropping system. The study was carried out on two faba bean varieties (<em>Alfia</em> and <em>Karabiga</em>) and barley in a farmer's field in the Haouz region of Marrakesh. At the flowering stage of faba bean plants, growth, nodulation, acid phosphatase (APase) and phytase enzymatic activities and P contents were assessed in all plants parts including their rhizospheric soils. The results showed that intercropping increased barley's growth, P uptake and APase activity in comparison with the monoculture, especially in association with <em>Karabiga</em> variety. This association presented the highest shoot dry weight (SDW) of 2.48 g plant⁻¹ and P content of 7.64 mg g⁻¹ DW. Meanwhile, faba bean presented significant reductions in these traits in intercropping system. The nodulation of both varieties was not significantly varied in response to intercropping. Overall, it seems that faba bean-barley intercropping was beneficial for barley in terms of increasing the P availability and uptake through the stimulation of APase activity in the in the nodules as well as in the rhizosphere.</p></div>","PeriodicalId":100092,"journal":{"name":"Annals of Agrarian Science","volume":"16 3","pages":"Pages 297-303"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasci.2018.05.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76840588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
