Effect of Integrating Plant Growth Regulators and Micronutrients on Growth, Phenology and Seed Yield of Fenugreek (Trigonella foenum-graecum L.)

Abstract

An experiment was conducted during Rabi 2019-20 at College of Agriculture, Indore (Madhya Pradesh) to investigate the effects of Plant Growth Regulator (PGRs) and Micro-nutrient Application on Growth, Quality, and Seed yield of Fenugreek (Trigonella foenum-graecum L.). The nine treatments consisted of different levels of PGRs i.e. GA3 and NAA with micro-nutrient (Mixol) which contain zinc, iron, manganese copper, boron and molybdenum including control (No use of PGRs and micro-nutrients) viz. T1 = 50 ppm GA3 seed treatment + Mixol 1.0%, T2 = 100 ppm GA3 seed treatment + Mixol 1.0%, T3 = 50 ppm GA3 foliar spray + Mixol 1.0%, T4 = 100 ppm GA3 foliar spray + Mixol 1.0%, T5 = 25 ppm NAA seed treatment + Mixol 1.0%, T6 = 50 ppm NAA seed treatment + Mixol 1.0%, T7=25 ppm foliar spray + Mixol 1.0%, T8 = 50 ppm NAA foliar spray + Mixol 1.0% and T9 = Control. Data were collected on different growth characters (Plant height and number of branches), Phonological attributes (Days to first flowering, days taken to 50% flowering and days to taken seed maturity) and yield characters (Seed yield per plant (g), seed yield t/ha, number of pods per plant, length of pod (cm), number of seeds per pod) of fenugreek. Based on results of one year experimentation, foliar spray of GA3 at 100 ppm + mixol 1.0% was found the best treatment compared with respect to plant growth and seed yield of fenugreek.
