Growth and yield of fenugreek (Trigonella foenum-graecum L.) as influenced by bio-fertilizers and chemical fertilizers

The field investigation was was conducted at Department of Plantation, Spices, Medicinal and Aromatic Crops of College of Horticulture, R.V.S.K.V.V. Mandsaur (M.P.) during the year 2020–2021. All the treatments accompanied such as bio-fertilizers (Azospirillum @ 5 kg ha⁻¹, Rhizobium@ 1.5 kgha⁻¹ and PSB@ 5 kg ha⁻¹) and chemical fertilizers (Nitrogen, Phosphorus and Potassium @40:20:20 Kg ha⁻¹), while the plants in the control plots were shown without any application of supplements in Randomized Block Design in three replications. Result revealed that, T₉ - 50% RDF + 50% Rhizobium recorded maximum plant height (11.90, 40.84, 73.33 and 76.24 cm), number of leaves (20.90, 44.77, 90.89 and 69.44 plant⁻¹), dry weight (0.19, 3.65, 19.71 and 22.08 g plant⁻¹), leaf area (22.76, 128.22, 147.35 and 124.53 cm² plant⁻¹), leaf area index (0.248, 0.451 and 0.453), lead area duration (22.32, 40.57 and 40.79), crop growth rate (0.039, 0.178 and 0.0484), relative growth rate (0.0417, 0.0925 and 0.0450), number of pod (82.51 plant⁻¹), number of seeds (15.91 pod⁻¹), pod length (12.21 cm), seed yield (9.72 g plant⁻¹ and 27.77 q ha⁻¹), biological yield (84.36 q ha⁻¹), test weight (12.80 g), harvest index (33.89%) and B: C ration (3.44:1) while, they were lowest in T₁ -control at 30, 60, 90 days after sowing and at harvest, respectively.
