Profile of relative humidity in wheat (Triticum aestivum L.) crop

Abstract

A field experiment was conducted at Research Farm, Dept of Agril Meteorology, CCS HAU, Hisar Haryana, India during the Rabi season in the 2017-18. Experimental designed laid out with split plot, as main plot treatment: three growing environment i.e. D1-1st week of November, D2-3rd week of November and D3-1st week of December with sub plot treatment viz., V1: WH-1105, V2: HD-3086, V3; HD-2967 and V4: WH-1080. Humidity in the atmosphere is of great biological importance. Measurements relative humidity was made at 2.30 hourly intervals throughout the observation day with the help of Psychrometric. The relative humidity profiles were lapse inside the crop canopy throughout the day but profiles were near iso-humic at 0930 hours in all treatments during both the crop seasons. Decrease in relative humidity with height from the ground.
