ASSESSMENT OF YIELD LOSSESS CAUSED BY BACTERIAL BLIGHT OF RICE IN UPPER DIR, KHYBER PAKHTUNKHWA PROVINCE

Abstract

The present study was conducted to assess the yield losses caused by bacterial brlight of Rice (Xanthomonas oryzae pv oryza) in Upper Dir a district of Khyber Pakhtunkhwa province of Pakistan during cropping season 2013-2014. Four rice growing locations of district namely Barawal Bandi, Satara, Maidan khwar and Thikar Kot were selected. In Upper Dir disease incidence (%) ranged between 57.14%-75% while disease severity (%) was between 36.04 to 66.12%. Highest disease incidence (75%) and disease severity (66.12%) was recorded from Barawal Bandi location whereas lowest disease incidence and disease severity was recorded from Thikar kot. Similarly maximum 1000 grain weight losses was also recorded in  Barawal Bandi while minimum 1000 grain weight loss was recorded in Thikar kot. It can be concluded that  Bacterial blight of rice was more severe in Barawal location and less severe in Thikar kot.
