An investigation on the “Effect of Planting Time and Spacing on Economics and Quality of Multiplier Onion (Allium cepa L. var. aggregatum Don.) cv. Meitei Tilhou” was carried out during the rabi season of 2019-20 in the Horticultural research field, College of Agriculture, CAU, Imphal from November 2019 to April 2020. The layout of the experimental field was carried out in Factorial Randomized Block Design (FRBD) with three levels of spacing (S1: 10 cm × 10cm, S2: 10 cm × 15cm, S3: 15 cm × 20cm) and four levels of planting time (P1: 10th November, P2: 25th November, P3: 10th December, P4: 25th December). From the present investigation, it was observed that quality parameters like TSS (21.36 0Brix) and Dry matter (17.34%) were higher at closer spacing (10 cm × 10cm).While better shape index of the bulb (1.32) and higher harvest index (79.91%) were recorded in wider spacing (15 cm × 20cm). Planting time had a significant effect on Dry matter content of the bulb and Harvest index; early planting time (10th November) recorded higher Dry matter (16.18%) and Harvest index (79.11%). The interaction of closer spacing 10cm×10cm and early planting date 10th November planting resulted in maximum gross returns (₹1,026,000/ha), net returns (₹ 843,591.50/ha), and higher benefit to cost ratio (B:C) of 4.62: 1.
