Proper potassium nutrition is critical for maximizing rice grain yields. Timing of K fertilizer application is an important management tool in maximizing K use efficiency. Maximum efficiency is acquired when K+ is applied so as to be available for uptake by the plants as needed. Unbalanced potassium fertilization has negative effects on crop quality and on crop resistance to pests and diseases. The purpose of the present study was to evaluate the effect of potassium on growth and yield of rice and to find out the best suited scheme / timing of potassium fertilizer application for rice crop. With this regard, pot experiments were conducted at the screen house of Department of Soil and Water Science, Yezin Agricultural University during the dry and wet season of 2014. In this investigation, a recommended dose of potassium fertilizer (37 kg ha-1) was used and eight treatments i.e. T1 (all potash applied as basal), T2 (all potash applied at 25 DAT), T3 (all potash applied at 45 DAT), T4 (½ potash applied as basal and remaining ½ at 25 DAT), T5 (½ potash applied as basal and remaining ½ at 45 DAT), T6 (½ potash applied at 25 DAT and remaining ½ at 45 DAT), T7 (1/3 potash applied as basal, 1/3 at 25 DAT and remaining 1/3 at 45 DAT) and T8 (Control - no K applied) were performed.\r\n\r\nBase on the two season results, yield and yield components with potassium use efficiency were responded to different time of potassium fertilizer application. T6 (½ potash applied at 25 DAT and remaining ½ at 45 DAT) and T2 (all potash applied at 25 DAT) produced more grain yield in both seasons. Lower grain yield was achieved at control and only basal application treatments. The greater potassium use efficiency was obtained by the application of potash at 25 DAT and two splits at 25 DAT and 45 DAT treatments. According to the results of this study, basal application of potash (traditional method) can be replaced by a late application of potash at 25 DAT and two equal split applications of potash at 25 DAT and 45 DAT can be promoted for getting maximum benefit. However, further investigations should be conducted to confirm the effect of potassium at field level."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Potassium"},{"interim":" fertilizer management"},{"interim":" split application"},{"interim":" rice yield"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-05-05"}],"displaytype":"preview","filename":"Khin Pyone Nwe (AGC - 81) THESIS.pdf","filesize":[{"value":"703 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/50/files/Khin Pyone Nwe (AGC - 81) THESIS.pdf"},"version_id":"9142f320-6d16-4b10-b5b5-a161f0015cad"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_journal_title":"Yezin Agricultural University"}]},"item_1583103147082":{"attribute_name":"Conference papaers","attribute_value_mlt":[{}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_supervisor(s)":[]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Nwe, Khin Pyone"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Thesis"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2015-09"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"https://yauor-yau.archive.knowledgearc.net/handle/123456789/248"},"item_title":"POTASSIUM FERTILIZER MANAGEMENT ON RICE CULTIVATION","item_type_id":"21","owner":"1","path":["1582969147534"],"publish_date":"2020-03-05","publish_status":"0","recid":"50","relation_version_is_last":true,"title":["POTASSIUM FERTILIZER MANAGEMENT ON RICE CULTIVATION"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T00:26:34.739684+00:00"}
