EFFECT OF WATER STRESS AND LIQUID PARAFFIN SPRAYING ON SEEDS YIELD AND ACTIVE CONSTITUENT TRIGONELLINE IN FENUGREEK (Trigonella foenum-graceum L.)

Abstract

A field experiment was conducted during the winter season of 2013-2014 in Silty loam texture soil to study the influence of water stress and spraying with liquid paraffin on seeds yield and Trigonelline concentration. Main plots concluded stopped irrigation after 122 and 157 days from sowing, the third treatment represented continuing irrigation until the end of the season, and foliar spray with 0 and 0.5% liquid paraffin as sub plot. The results showed that full irrigation gave significant increase in seeds yield kg ha-1 and concentration of Trigonelline mg kg-1 (2167.3 and 1.043) respectively, whereas the foliar spraying of liquid paraffin (0.5%) gave significant increase of seed yield kg ha-1 (1757.61). The interaction between full irrigation and foliar spraying of (liquid paraffin 0.5%) had significant effects on seed yields and concentration of Trigonelline were 2282.3 kg h-1 and 1.141 mg kg-1 respectively.
