Performance of Integrated Nutrient Management and Foliar Spray of Micronutrients on Growth, Yield Attribute and Yield of Wheat (Triticum aestivum L.)

A field experiment was conducted during two rabi seasons of 2021-2022 and 2022-23 at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology Kanpur, (U.P.) The experiment was caried out in SPD (Split Plot Design) with fifteen treatment combination were replication thrice. fifteen treatment treatments combination consisted of three organic manure + RDF nutrient source (Control (100% RDF), 100 % RDF + Vermicompost @ 2.5t/ha, and 100 % RDF + FYM @ 5t/ha) put under main plot and five foliar spray of micronutrient control (No spray),Foliar spray of ZnSO4 @ 0.25% at tillering and booting stages, Foliar spray of Nano Zinc @ 0.5% at tillering and booting stages, Foliar spray of FeSO4 @ 0.25% at tillering and booting stages and M5- Foliar spray of ZnSO4 @ 0.25% + FeSO4 @ 0.25% at tillering and booting stages) allotted under sub plot. The study on yield attribute and yield of wheat. The result showed that the maximum increase growth parameters, yield attribute and yield of wheat viz plant height (cm), number of tillers/m2, and leaf area index and number of grain/spike, number spike/m2, total grain weight spike (g) and test weight (1000 grain weight) (g) and grain yield (t/ha) and straw yield (t/ha) recorded significantly higher with F2- 100 % RDF + Vermicompost @ 2.5t/ha treatments. Among the sub plot, M5- foliar spray of ZnSO4 @ 0.25% + FeSO4 @ 0.25% at tillering and booting stages produced significantly maximum highest grain yield (5.95 t/ha) and straw yield (7.94 t/ha)
