Abstract:The present experiment was conducted during
Kharif season 2018-19 and 2019-2020 at Agronomy farm, Department of Agronomy, College of Agriculture, Dapoli to study the correlation between blue beetle incidence and weather parameters.
Results revealed that morning relative humidity in S1V1 (r=0.702), S1V2 (r=0.661), S1V3 (r=0.739), S1V4 (r=0.684), S1V5 (r=0.746), S1V6 (r=0.762), S1V7 (r=0.705), evening relative humidity in S1V1 (r=0.597), S1V3 (r=0.638), S1V4 (r=0.572), S1V5 (r=0.612), S1V6 (r=0.638), S1V7 (r=0.605) was found to be positively significant. While, maximum temperature in S1V1 (r=-0.704), S1V2 (r=-0.622), S1V3 (r=-0.711), S1V4 (r=-0.650), S1V5 (r=-0.684), S1V6 (r=-0.708), S1V7 (r=-0.677), S1V8 (r=-0.579), S2V5 (r=-0.618), S2V6 (r=-0.616), S2V8 (r=-0.582) and bright sunshine hours S1V1 (r=-0.585), S1V2 (r=-0.591), S1V3 (r=-0.670), S1V4 (r=-0.601), S1V5 (r=-0.666), S1V6(r=-0.687), S1V7 (r=-0.638) was found to be negatively significant. Remaining all of the weather parameters were found to be non-significant.
