Abstract: An investigation was carried out to study the effect of different spacing’s and different levels of fertigation on quality parameters and cost economics of onion (Allium cepa L.) hybrid Arka Lalima at the Precision Farming Development Centre (PFDC), Department of Horticulture, UAS, GKVK, Bengaluru during 2015-16. The experiment was laid out in Randomized Complete Block Design with thirteen treatments and three replications. The performance of six spacings and fertigation at 80 per cent recommended dose of fertilizers (100:60:100 kg NPK ha -1) and 100 per cent recommended dose of fertilizers (125:75:125 kg NPK ha -1) with water soluble fertilizers (19: 19: 19, Urea and SOP) through drip fertigation was compared with soil application of normal fertilizers (Urea, DAP, MOP) and normal spacing 15 cm × 10 cm.The results revealed that treatment 5 i.e., Fertigation with 80 per cent recommended dose of fertilizers and plants spaced at 20 cm × 15 cmrecorded maximum bulb volume,(122.63 cc) Total soluble solids(12.17) brix and highest pungency (7.1 µ mol g-1) gross return (Rs.11,50,000), net returns (Rs.848301) and benefit cost ratio of (1:2.81)lowest bulb volume (41.53 cc),total soluble solids (10.01) brix, (gross returns Rs 7,08,000, net returns Rs. 2,57,682.06 and benefit cost ratio of 1: 0.72) was noticed incontrol (T13) in case of soil application of recommended dose of fertilizers and recommended spacing. But pungency was significantly lowest in T7(4.04 µ mol g-1) this might be due to smaller bulb size. From this investigation it can be concluded that fertigation with 80 percent recommended dose of fertilizers i.e., (100:60:100 kg NPK /ha) and the plant spaced at20 cm × 15 cm is ideal for getting goodquality parameters and economic returns of onion hybrid Arka Lalima by saving fertilizers cost nearly 20 per cent.
