Performance of onion (Allium cepa L.) varieties for growth and yield parameters under central dry zone of Karnataka

Abstract

A study was conducted to ascertain the production potentials of different varieties of onion (Allium cepa L.) were carried out at Zonal Agricultural and Horticultural Research Station, Hiriyur, Chitradurga District, Karnataka during kharif season of 2013-14. A study comprises 14 varieties (Agri Found White, Arka Pragathi, N-53, Arka Niketan, Poona Pursangi, ArkaKalyan, Bhima Super, Mahalakshmi, Agri Found Dark Red, Agri Found Light Red, Satara Garva, Prema-178, NHRDF Red, and Bellary Red) and evaluated for growth and yield parameters under Central Dry Zone of Karnataka to identify the high yielding varities and were tested at this centre and laid out in randomised complete block design with three replications. The results revealed that, the highest and significant total bulb yield (282.63 q/ha) and marketable yield (251.83 q/ha) were recorded in the genotype Bhima Super. The parameters like polar diameter of bulb (4.98 cm), equatorial diameter of bulb (5.46 cm) and Average bulb weight (69.33 g) recorded significantly higher in the genotype Bhima Super.
