Abstract:A field experiment was conducted during
Kharif and
Rabi season of 2017-18 and 2018-19 at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur in alluvial track of Gangetic plains in Central part of Uttar Pradesh. The field experiment was laid out in Randomized Block Design with twelve treatments
viz., T1: Control, T2: 125% RDN, T3: 100% RDN, T4: 100% RDN + 25% N through FYM, T5: 100% RDN + 25% N through Vermicompost, T6: 100% RDN + S (30 kg ha-1), T7: 100% RDN + S (30 kg ha-1) + Zn (5 kg ha-1), T8: 100% RDN + S (30 kg ha-1) + Zn (5 kg ha-1) + Fe (10 kg ha-1), T9: 100% RDN + S (30 kg ha-1) + Zn (5 kg ha-1) + Fe (10 kg ha-1) + B (1 kg ha-1), T10: 100% RDN + S (30 kg ha-1) + Zn (5 kg ha-1) + Fe (10 kg ha-1) + B (1 kg ha-1) + Azotobacter + PSB, T11: 100% RDN + 25% N through FYM + S (30 kg ha-1) + Zn (5 kg ha-1) + Fe (10 kg ha-1) + B (1 kg ha-1) + Azotobacter + PSB and T12: 100% RDN + 25% N through Vermicompost + S (30 kg ha-1) + Zn (5 kg ha-1) + Fe (10 kg ha-1) + B (1 kg ha-1) + Azotobacter + PSB and replicated thrice. After making individual experimental unit, the amount of fertilizer was applied as per treatment uniformly.
In hybrid rice crop, integrated nutrient management improved the growth and yield attributes such as panicle length, no. of grain per panicle, test weight and yield over the 100% RDN alone. The maximum improvement was notice with the application treatment T12 (100% RDN + 25% N through Vermicompost +S + Zn + Fe + B + Azo. + PSB) over the rest of the treatments. Similar trend was also observed in case of wheat crop. Application of treatment T12: 100% RDN + 25% N through Vermicompost +S + Zn + Fe + B + Azo. + PSB produced maximum number of growth attributed and yield was recorded.
