dc.description.abstractEn v - factors such as relative humidity and rainfall generally have been found to increase the incidence, I'd: and severity of diseases thereby reducing yield of crops. Study was conducted on five cotton varieties, arti , ■:dated with bacterial blight pathogen to determine the effects of rainfall and relative humidity on inch ' sew . eas higher in Yola (58.657c) at 13 WAS is assumed to be due to higher relative humidity (76-877o) and :• . ■ (2 - 40.6 mm) which favours disease development as against that of Mubi location which recorded lower ■ 5Li 17c) due to lower relative humidity (42 - 557o) and rainfall (37 - 73 mm). Results further revealed that 5AMCOT-8 had low incidence and severity in both locations with an incidence of667o and severity of 397c of ALS t- . 13 WAS in Yola and S27o incidence and 427o severity in Mubi. SAMCOT-10 and SAMCOT-9 varieties wen- found to be highly susceptible to the disease at the same period. SAMCOT-8 recorded the highest yield of 390.00 kgha'1 in Yola and 868.09 kgha'1 in Mubi while lowest yields of 227.17 kgha'1 was observed on SAMCOT-10 in Yola and 461.61 kgha'1 was obtained on SAMCOT-9 in Mubi. There is need to conduct further trials in these locations to confirm the reaction of these varieties. ' .verity of angular leafspot (ALS) and yield of seed cotton in Yola and Mubi.
