Effect of Integrated Nutrient Management on Growth Yield and Quality traits of Sprouting Broccoli Brassica oleracea L var italica Plenck

Abstract

The present investigation entitled Effect of integrated nutrient management on growth, yield and quality traits of sprouting broccoli (Brassica oleracea L.var. italica Plenck). was carried out during Rabi season in consecutive years, 2021-22 and 2022-23 at the Vegetable Research Farm, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kalyanpur, Kanpur. The experiment was laid out in randomized block design with three replications. The soil of the experimental site was sandy loam in texture, low in organic carbon and medium in available nitrogen, phosphorus and potassium. The treatments consisted of T0: Control, T1: 100% RDF at 120: 80: 60, N: P: K (kg/ha), T2: 75% RDF + 25% N through FYM, T3: 75% RDF + 25% N through Vermicompost, T4: 75% RDF + 25% N through FYM + Biofertilizer, T5: 75% RDF + 25% N through Vermicompost + Biofertilizer, T6: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost, T7: 75% RDF + 12.5% N through FYM + 12.5% N through Vermicompost + Biofertilizer, T8: 50% RDF + 50% N through FYM, T9: 50% RDF + 50% N through Vermicompost, T10: 50% RDF + 50% N through FYM + Biofertilizer, newlineT11: 50% RDF + 50% N through Vermicompost + Biofertilizer, T12: 50% RDF + 25% N through FYM + 25% N through Vermicompost and T13: 50% RDF + 25% N through FYM + 25% N through Vermicompost + Biofertilizer. Biofertilizer includes Azotobacter + PSB (at 5 kg each per ha.) Results revealed that the treatment T11: 50% RDF + 50% N through Vermicompost + Biofertilizer, performed better with respect to growth characters at harvesting stage, with maximum values for plant height (51.67 cm), number of leaves per plant (19.03), length of leaf (49.47 cm), width of leaf (26.48 cm), plant spread (69.43 cm), stalk length (21.46 cm), stalk diameter (4.33 cm), yield and yield contributing characters, days taken to first head initiation (51.00 days), days taken to 50% head initiation (55.00 days), days taken to head maturity (71.67 days), weight of head with guard leaves (1290.62 g)
