SUMMARY
An experiment was conducted under rainfed condition at Hisar, Haryana to study the influence of various agro-meteorological parameters (Agromet) i.e. temperature (Maximum & minimum), rainfall (mm), soil temperature (°C), radiation (MJm-1day-1), photosynthetically active radiation (PAR) in pearl millet. The research covers critical growing environments months of June, July and followed by 1 week of August (only in D3: 7 August 2021, late sown) in a semi-arid region, providing insights into how these factors interact and affect pearl millet development. The prevailing micrometeorological conditions within the canopy, wind speed (km/hr) and cloudiness on the growth and yield of pearl millet were impacted as the diurnal based. Results indicate that optimal growth is associated with specific ranges of rainfall, air temperature, soil temperature & moisture, and radiation components levels. On a rainy-day rainfall in the crop field reached a soil depth of 4.5 to 6 cm when a single day received ±2.5 millimetres of rainfall. The pearl millet crop was influenced as an average 12 rainy day and 9 crop rainy day required to complete the life cycle. An average ~49% deviation of rainfall over the normal was good and successfully harvested the pearl millet, in the positive %deviation of rainfall was negative or altered influenced to the third growing environment in this region. The grain and straw yield showed negative significant correlation with morning relative humidity.
Key words: Pearl millet, weather entities, semi-arid region, temperature, rainfall, crop yield
