Effect of pinching and plant growth regulators on yield and quality of fenugreek (Trigonella foenum-graecum)

A field experiment was conducted to find out the effect of pinching and plant growth regulators on yield and quality of fenugreek (Trigonella foenum-graecum L.) cv. Pant Ragini during 2020-21 at Department of Horticulture, H N B Garhwal University, Srinagar (Garhwal), Uttarakhand. Minimum days taken to first and 50 % first pod formation (89.88 and 93.97 days), significantly maximum length of pod (11.23 cm), pod diameter (2.13 mm), pods/plant (51.85), number of seeds/pod (18.92), seed yield/plant (8.02g), seed yield/plot (657.78 g) and seed yield/ha (39.70 q), and quality parameters, viz. TSS (13.08 ⁰Brix) and ascorbic acid (60.73 mg/100g) were recorded with seed soaking of S₁ (GA₃ 50 ppm). Among plant growth regulators, foliar spray of G₁ (GA₃ 50 ppm) twice (30 and 60 DAS) took minimum days to first and 50 % first pod formation (89.88 and 93.97 days), maximum length of pod (11.23 cm) and pod diameter (2.13 mm), number of pods/plant (51.87), number of seeds/pod (18.85), seed yield/plant (7.86g), seed yield/plot (609.62 g) and seed yield/ha (37.13 q) and quality parameters, viz. TSS (13.75 ⁰Brix) and ascorbic acid (62.29 mg/100g) of different pinching applications, P₁ (no pinching) took minimum days to first and 50 % first pod formation (90.55 and 94.31 days) and different yield application of P₂ (double pinching at 60 DAS) were maximum length of pod (10.91 cm), pod diameter (2.50 mm), number of pods/ plant (54.87), number of seed/pod (18.61), seed yield/ plant (7.11 g), seed yield/plot (596.40 g) and seed yield/ha (35.51 q), highest TSS (11.73 ⁰Brix) and ascorbic acid (60.16 mg/100g).
