Abstract:
A field experiment was conducted at New Area, Department of Millets, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during Thaipattam (January-February) 2021 on sandy clay loam. Eight treatments were followed with boron nutrition. T₁ : Recommended Dose of Fertilizer (RDF = N, P, K, S, Zn), T₂ : RDF + 5 kg/ha boron ( Soil application), T₃ : RDF + 2.5 kg/ha boron (Soil application) + 0.2% foliar spray at panicle initiation (PI) and flowering, T₄ : RDF + 2.5 kg/ha boron (Soil application) + 0.4% foliar spray at panicle initiation (PI) and flowering, T₅ : RDF + 2.5 kg/ha boron (Soil application) + 0.6% foliar spray at panicle initiation (PI) and flowering, T₆ : RDF + 0.2% foliar spray at panicle initiation (PI) and flowering, T₇ : RDF + 0.4% foliar spray at panicle initiation (PI) and flowering, T₈ : RDF + 0.6% foliar spray at panicle initiation (PI) and flowering and were tested in randomized block design with three replications. Results indicated that application of RDF + 2.5 kg/ha boron (Soil) + 0.6% foliar spray at PI and flowering (T₅) registered higher plant height, dry matter production, panicle length, 1000 grain weight, filled grains panicle^-1 and grain yield over the control (T₁).
