Effect of Different Spacing and Varieties on Growth, Quality and Yield in Onion (Allium cepa L.)

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).
