Comparative Studies on Effectiveness of Physical, Micronutrients, PGR and Botanical Seed Treatments on Growth and Yield of Fenugreek (Trigonella foenum-graecum L.)

Abstract

The experiment was carried out at a field experimentation centre, Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagraj (U.P). During Rabi season 2020-2021, to find out the suitable electric, magnetic, micronutrients, plant growth regulators and botanical seed treatments on growth and yield of Fenugreek (LFC-84). Different concentrations with different duration of seed treatments with control (untreated) were evaluated by screening 8 hours viz., Electric treatment (0.5A for 60 seconds and 1.0A for 60 seconds), Magnetic treatment (10mT for 15 min and 20 mT for 30 min), ZnSO4 (1% and 3% for 8 hrs), MnSO4 (1% and 3% for 8 hrs) Ascorbic acid (100 ppm and 300 ppm for 8 hrs), Moringa leaf extract (1% and 3% for 8 hrs). It has been reported that among all the treatments T6 - ZnSO4 -3% for 8 hrs has performed the best results in field parameters like field emergence, Plant height, number of branches per plant, days required to 50% flowering, days required to 50% pod formation, days to maturity, number of pods per plant, number of seeds per pod, seed yield per plant (g), test weight (g), biological yield (g), harvest Index (%) followed by Ascorbic acid 300 ppm for 8 hours and found to be lowest in control seeds. Hence seed treatment of Fenugreek seeds with ZnSO4 (3%) for 8 hours is the best treatment compared to other seed treatments.
