Comparison Analysis of Tajuk's Onion Production Efficiency (Allium Ascalonicum) in Rejoso Sub-District-Nganjuk

Nganjuk is one of production area for Tajuk's onion. This research aimed to compare the results of technical and allocation efficiency from Tajuk's onion production in rejoso sub district, whether there are any differences or not.
