Abstract
Agro meteorological conditions cause wide fluctuations in growth, development and yield of finger millet crop. Crop performance data on the popular finger millet crop variety INDAF-8, collected from field experimentation at Bengaluru during the period 1985-2001 was used to understand the role of the weather on finger millet yields. Among 10 weather variables / indices studied minimum temperature (Tmin), diurnal temperature range (DTR) and moisture adequacy index (MAI) were found to influence finger millet yields. Tmin during 4th to 8th fortnight after sowing (FAS) and MAI during 8th FAS were found to have a strong positive correlation with yields. DTR at 6th FAS and the frequency of days in a season above a threshold value of 11°C were found to have an impact on the finger millet yields. Step-wise regression technique resulted in identifying Tmin and MAI as critical weather parameters influencing the yields. An yield prediction model was developed that uses Tmin during 4th to 8th, DTR at 6th FAS and MAI during 8th FAS accounted for 63% variability in yields.
