Abstract
A field experiment was conducted at the farmers field in Auard village of Jewargi taluk in Kalaburagi district of Karnataka state during Kharif 2024 to study the effect of sulphur, zinc and boron on the yield and quality of chilli in Vertisol. The experiment was laid out in a RCBD with ten treatments replicated thrice. The results revealed that the application of 100% RDF + sulphur @ 30 kg ha-1 through bentonite sulphur (90%) + 0.1% zinc EDTA (12%) + 0.2% Solubor (19%) as foliar spray at flower initiation (45 days), flowering (60 days) and fruiting (75 days) stages recorded significantly higher nutrient uptake and economics viz. nitrogen, phosphorus, potassium, sulphur, zinc and boron uptake and was statistically on par with 100% RDF + sulphur @ 20 kg ha-1 through bentonite sulphur (90%) + 0.05% zinc EDTA (12%) + 0.1% Solubor (19%) foliar spray at the same stages while the lowest values were recorded in control.
