Abstract
The study entitled standardization of fertigation schedule and foliar sprays of micronutrients in onion (Allium cepa L.) was conducted at Horticulture farm, Main Agricultural Research Station, UAS, Raichur during 2018-19 to know the effect of fertigation and foliar sprays on growth, yield, quality and economics of onion cultivation. The use of WSF at 125 per cent RDF in combination with foliar sprays of boron (0.25 per cent) and ZnSO4 (0.5 per cent) significantly increased the important growth parameters such as plant height (79.98 cm), leaf length (75.25 cm) and dry matter content (25.35 g plant-1). Application of WSF at 75 per cent RDF through fertigation combined with foliar sprays of boron (0.25 per cent) and ZnSO4 (0.5 per cent) enhanced the yield and yield attributes such as bulb diameter (6.96 cm), average bulb weight (172.17 g), bulb yield per plot (32.80 kg) and yield per hectare (65.60 t ha-1). Application of WSF at 100 per cent RDF through fertigation in combination with foliar sprays of boron (0.25 per cent) and ZnSO4 (0.5 per cent) resulted in significantly maximum TSS (15.03 oB) and pungency (10.94 μmol/g). Among all treatment combinations of fertigation and foliar sprays, WSF at 75 per cent RDF + boron (0.25 per cent) and ZnSO4 (0.5 per cent) resulted in maximum (6.10) B:C ratio and minimum was recorded (3.48) in surface irrigation with 100 per cent RDF combined with water spray
