Abstract

Influence of weather on pokkah boeng disease in sugarcane under North-West Alluvial Plains (Zone I) of Bihar

Highlights

  • The data on disease development and their angular transformed values as well as prevailing environmental factors presented in Table 1 reveal that disease incidence varied from 0.5 to 14.9 per cent during the course of investigation

  • The maximum incidence (14.9 per cent) of disease was observed during last week of August followed by 14.2 and 13.6 per cent during 1st and 2nd week of September, respectively

  • The correlation analysis revealed that minimum temperature, relative humidityand rainfall exibited significant positive correlations (r = 0.69**, 0.60**, 0.80** and 0.50**) with disease incidence, whereas maximum temperature and sunshine had significant negative relationship (r = -0.59** and -0.71**)

Summary

Introduction

The data on disease development and their angular transformed values as well as prevailing environmental factors presented in Table 1 reveal that disease incidence varied from 0.5 to 14.9 per cent during the course of investigation. The maximum incidence (14.9 per cent) of disease was observed during last week of August followed by 14.2 and 13.6 per cent during 1st and 2nd week of September, respectively. The maximum incidence (14.9 per cent) was recorded when corresponding weather factors viz., maximum temperature (°C), minimum temperature (°C), relative humidity (%) at 700 hrs.
