Effect of plant population density and varietal differences on yield and yield components of onion (Allium cepa L.) in North Eastern Nigeria
Abstract
Onion is grown extensively during dry season in the North eastern Nigeria for bulb as well as leaves production. The local producers were known to use random density planting in the field. This study is aimed to determine the optimum plant density for different local cultivars (Ex-Borno, Kano Red, Local Red and White). Trials were carried out at Bululu irrigation site of Bade District in Yobe State, Nigeria during 2010/2011 and 2011/2012 season. The results indicated that the cultivars respond well with the 30 plants/m2 while the Ex-Borno cultivar proved to be prominent among the cultivars studied with an average of 6.406t/ha.
