Abstract
A comprehensive study examining the effects of organic and inorganic nutrient sources on the growth and yield of wheat was carried out during the Rabi season of 2020-21 at the Student's Instructional Farm, C.S. Azad University of Agriculture and Technology, Kanpur. The experimental design was a Randomized Block Design, with each treatment replicated three times across eight different treatments: Control (T1), 100% Recommended Dose of Fertilizers (RDF) (120:60:40 NPK kg/ha) (T2), RDF + Azotobacter (T3), RDF + Azotobacter + Farmyard Manure (FYM) @ 2.0 tons/ha + Phosphate Solubilizing Bacteria (PSB) @ 6.0 kg/ha + Trichoderma @ 5.0 kg/ha (T4), RDF + Vermicompost @ 2.5 tons/ha (T5), RDF + FYM @ 2.0 tons/ha + Vermicompost @ 1.0 ton/ha + Trichoderma @ 5.0 kg/ha (T6), RDF + FYM @ 2.0 tons/ha + Vermicompost @ 1.0 ton/ha + PSB @ 6.0 kg/ha + Azotobacter (T7), and RDF + FYM @ 2.0 tons/ha + Vermicompost @ 1.0 ton/ha + Azotobacter + PSB @ 6.0 kg/ha + Zinc @ 5.0 kg/ha + Sulphur @ 25 kg/ha (T8). The soil type was sandy loam with a pH of 8.13. The wheat variety Shekhar (K-1006) was planted on November 30, 2020, with a seed rate of 100 kg/ha and row spacing of 20 cm. The results indicated that the T8 treatment, which combined RDF, FYM, Vermicompost, Azotobacter, PSB, Zinc, and Sulphur, significantly improved plant growth characteristics such as height, fresh weight, dry weight, and number of tillers per plant, as well as yield-contributing factors including spike length, number of grains per spike, and test weight, compared to all other treatments. Specifically, the T8 treatment produced the highest grain yield, straw yield, and biological yield, recording 52.77, 67.55, and 120.32 quintals per hectare, respectively, which was significantly higher than the yields in treatments T1, T2, T3, and T4, and comparable to those in treatments T5, T6, and T7. Moreover, the T8 treatment achieved the highest gross income (Rs. 143,076.00), net income (Rs. 86,300.00), and benefit-cost ratio (2.52) when compared to all other treatments.
