Influence of gibberellic acid on growth and quality of fenugreek (Trigonella foenum-graecum L.)

Abstract

Gibberellic acid (GA3) at 50 ppm, 75 ppm, 100 ppm and 125 ppm was sprayed to fenugreek at 40 and 60 days after sowing. GA3 @ 100 ppm promoted growth and produced highest yield (12.60 q ha-1), followed by GA3 @ 75 ppm (12.05 q ha-1) which, however, was at par with GA3 @ 100 ppm. Among quality parameters, carbohydrate was highest (45%) with GA3 @ 125 ppm whereas, crude protein content was highest (29.33%) with GA3 @ 75 ppm. The highest oleoresin content (0.3%) and highest essential oil content (2.8%) was recorded with GA3 @ 100 ppm.
