The effect of different level of boron yield, quality and shelf life of knol-khol indicated that the boron level T₉ (RDF + Borax 2 kg soil application +0.2% B through borax as foliar application) recorded maximum average weight of knob (183.7 g), knob yield/ ha (98.43 q), marketable knob yield per plot (8.51 kg), marketable yield per ha (91.64 q) and B:C ratio (2.43). Where as treatment T₁₀ (RDF + Borax 3 kg soil application + 0.3% B through borax as foliar application) recorded significantly better quality parameters i.e. total soluble solids (5.2°Brix), dry matter (7.14%), ascorbic acid content (55.21 mg/100 g), less cracking percentage (5.15%) and shelf life (7.66 days) as compared to others. Overall precise boron application was proved to be beneficial for good knob, less cracking percentage, higher marketable yield, better quality and more shelf life of knol-khol.
