It was observed that 98.89% out of 44 fields sampled were infested with the rice root nematode, H. oryzae. Based on the prominence value (a combination of the frequency of occurrence and abundance) of H. oryzae, the highest population was found in Tatkon Township and the lowest in Lewe Township. The highest population of H. oryzae from soil and root were observed in Sinthukha and the lowest population was found in Shwethweyin. All summer rice varieties surveyed were observed to be either susceptible or highly susceptible to H. oryzae. In two different cropping sequences, rice-blackgram-rice cropping sequence had the lower nematode population than that of rice-rice cropping one. Moreover, the lower nematode population was also found in direct seeding than in transplanting method. The tested 12 rice varieties were inoculated with 2000 nematodes per plant. Plant height, tiller number, fresh shoot weight, fresh root weight, dry shoot weight, filled grain percent, 1000 grain weight and final nematode population were recorded at harvest. Among tested 12 rice varieties, Yet-90 and Sinthukha were rated as highly susceptible and Pawsanmwe and Manawthukha as susceptible to H. oryzae. The other eight varieties; Thukhamwe, Pyitawyin, Salt tolerant Sinthwelatt, Shweasean, Myaungmyamay, Pyimyanmarsein, Submergence\r\ntolerant 1 and Shwethweyin were found as moderately resistant varieties. Conclusively, the most infested region was Tatkon Township in Nay Pyi Taw Union Territory and the only economical way to control rice root nematode is the use of resistant rice varieties and avoidance of monocropping and transplanting practices."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Rice Root Nematode"}, {"interim": " Hirschmanniella oryzae"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "filename": "Ei Ei Mon (PTY-93) Thesis.pdf", "filesize": [{"value": "2673 Kb"}], "format": "application/pdf", "licensetype": "license_free", "mimetype": "application/pdf"}]}, "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": "Mon, Ei Ei"}]}]}, "item_1583108359239": {"attribute_name": "Upload Type", "attribute_name_i18n": "Upload Type", "attribute_value": "Publication"}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_name_i18n": "Publication type", "attribute_value": "Thesis"}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_name_i18n": "Publication date", "attribute_value": "2018-11"}, "item_title": "Population Density of Rice Root Nematode, Hirschmanniella oryzae (Luc and Goodey, 1964) in Nay Pyi Taw Union Territory and Response of Some Rice Varieties", "item_type_id": "21", "owner": "1", "path": ["1582963567848/1582969177975"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000186", "publish_date": "2020-03-05", "publish_status": "0", "recid": "186", "relation": {}, "relation_version_is_last": true, "title": ["Population Density of Rice Root Nematode, Hirschmanniella oryzae (Luc and Goodey, 1964) in Nay Pyi Taw Union Territory and Response of Some Rice Varieties"], "weko_creator_id": "1", "weko_shared_id": -1}
