Abstract

Hairamine a protein hydrolysate obtained from human hair is a growth promoter as a biostimulant. A field experiment
was conducted at the Research Farm of the Faculty of Agriculture, Maharishi Markandeshwar (Deemed to be University),
Mullana, Ambala (133207) during the Rabi season of 2023-2024 to evaluate the response of three wheat varieties DBW
222, WH 1270 and DBW 303 to Hairamine for its effect on grain yield and its attributes. The experiment was conducted
in randomized block design with three replications. Three foliar sprays of Hairamine 4 ml/litre of water were applied at
30, 60, 90 days after sowing. Observations were recorded on 5 randomly selected plants from each plot for plant height,
chlorophyll content, nitrogen content, stem girth, stem strength, angle of declination, number of grains per spike, test
weight, grain yield and bacterial population. The rhizospheric soil was analysed for microbial colonies in control and
Hairamine treated plots. Significant increase in various plant characters and microbial colony number was observed in
Hairamine treated plots in all the three varieties. The grain yield and stem strength were enhanced by 14.5% and 25.4%,
respectively. Therefore, Hairamine application can be recommended as potential bio stimulant for increasing grain yield
and lodging resistance in wheat under climate change.
