Present investigation on ‘Responses of crop geometry, bio-fertilizers, and phytohormones on seed yield and quality traits of fenugreek (Trigonella foenum graecum L.). Carried out during winter season (2020-21 and 2021-22) at research field of Department of horticulture, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwavidyalaya, Gwalior Madhya Pradesh. The field experiment consists twelve treatments combinations of two spacing (30 cm ×10 cm and 25 cm ×15 cm), three Bio-fertilizer (Rhizobium, Phosphate Solubilizing Bacteria and Potassium Mobilizing Bacteria) and two levels of phytohormones (GA3@200 ppm and NAA @100 ppm). The work was conducted in FRCB Design with three replications. The significantly maximum value of yield attributes viz., No. of pods / plant (50.68), Pod length (21.20 cm), Pod weight (0.3174 g), No. of seeds / pod (16.21), Test weight of seeds (16.04 g) Seed yield (0.96 kg/plot) and Seed yield (21.22 q/ha) under the S₁– (30 cm ×10 cm) spacing. Whereas significantly maximum value of quality traits viz., Protein (24.82%), Carbohydrate content (47.41%), Vitamin-A (61.09 IU), Ascorbic acid (4.98 mg/100 g), Fat (7.55 g/100 g) also recorded under the S1 (30 cm ×10 cm) spacing. The highest value of yield attributes viz., No. of pods / plant (51.58), Pod length (21.49 cm), Pod weight (0.3183 g), No. of seeds/pod (16.68), Test weight of seeds (16.49 g) Seed yield (0.97 kg/plot) and Seed yield (21.59 q/ha) were found to be significantly maximum with seed inoculation with Rhizobium. The significantly highest value of quality traits viz., Protein (24.93%), Carbohydrate content (47.55%), Fat (7.88 g/100 g) also were found to be significantly when seeds inoculation with Rhizobium, while Vitamin-A (61.13 IU) and Ascorbic acid (5.14 mg/100 g) significantly maximum when seeds inoculation with Phosphate Solubilizing Bacteria. Foliar spray of GA₃ @200 ppm was significant higher in yield attributes viz., No. of pods / plant (51.66), Pod length (21.17 cm), Pod weight (0.3186 g), No. of seeds/pod (16.91), Test weight of seeds (16.51 g) Seed yield (1.00 kg/plot) and Seed yield (22.11 q/ha). Foliar spray of GA3 @200 ppm also was found significant higher in yield attributes viz., Protein (24.54%), Carbohydrate content (47.53%), Vitamin-A (61.12 IU), Ascorbic acid (5.01 mg/100g), Fat (7.83 g/100 g). All interaction effects were non-significant, except spacings x growth regulators (A x C) which were significant for yield and quality traits- No. of pods / plant and Carbohydrate content %.
