Abstract
Aim of this experiment is to study the impact of irrigation techniques on microclimate of wheat crop in terms of temperature and humidity. Randomized block design is used on the wheat crop (Triticum aestivum L.) variety Karan Narendra (DBW 222) at research farm of ICAR-CSSRI, Karnal during the Rabi 2021-22. In conventional practice treatment, higher temperature fluctuation was observed and was 0.5-1°C cooler as compared to other plots. Drip irrigation treatment showed most stable crop microclimate in terms of canopy temperature and humidity dynamics. A sharp rise in temperature at maturity cause dryness in crop and leads to lower productivity. Except at physiological maturity, canopy was cooler than the ambient air, while relative humidity was higher both during morning and evening hour.
