Abstract
The present experiment was conducted at the field of Horticulture Research Farm, Babasaheb Bhimrao Ambedkar University, Lucknow (Uttar Pradesh) during rabi season of 2019-2020. The experiment was laid out in factorial randomized block design (FRBCD) and treatments comprised of three varieties i.e. V1 (Agrifound Light Red), V2 (NHRDF-Red), V3 (NHRDF-2) and three planting spacing S1 (20×7.5cm), S2 (20×10cm) and S3 (20×15 cm). The parameters were observed viz. plant height (cm), number of leaves /plants, neck thickness (cm), bulb diameter (cm), Number of scales, bulb length (cm). TSS (ᵒbrix), ascorbic acid (mg/100gm ), total sugar (%), reducing sugar (%), non- reducing sugar (%), acidity (%) yield per plot (kg) and yield per hectare (q).The results of this study revealed that the combination application of variety (Agrifound Light Red ( V1) with spacing 20X 15 cm ( S3) was best under Lucknow conditions and lowest values were noted in of variety Agrifound Light Red ( V1) with spacing 20X 7.5 cm (S1).
