Do they like extra fertilizer during their growth?
Or is it better to fertilize with dried cowdung a week before planting?

Depends how much of a crop you want. Tubers can be heavy feeders. You can start with amended soil, and then once a month supplement with an acidic form of nitrogen and a source of soluble phosphate. If you want to be "organic" I would recommend Fish Emulsion for the Nitrogen and Bone Meal for the phosphate -- but apply the bone meal about 3 weeks ahead of schedule. If you don't mind using water-solubles then I'd recommend using 21-7-7 Acid Forming formula with 11-45-8 Tuber Enhancer.
