Ultrasonic (US) – induced growth and yield potentials of fenugreek (Trigonella foenum-graecum L.) plants under SO2 fumigation

Abstract

The fenugreek plants raised from seeds preconditioned with 2 MHZ ultrasound were found better suited to mild doses of SO2 applied under fumigation experiments. The leaf dry matter was promoted to the extent of 66.3percent at T4 – S1 and leaf area upto 42.2 percent at the same treatment. The seed yield was favoured to higher degree with 69.7 percent enhancement at T2 – S1 and 67.0 percent at T3 – S1.
