| Abstract | The experimental study was for the field trials of yield response and soil nutrient change of sweet potato varieties to different fertilization treatment conducted atthehighland agricultural development station under the royal initiative, Ban Pa Kha, Kamphaeng Phet, Thailand. The objectives of this research are to compare yield weight and soil nutrient change of sweet potatounder different fertilizer uses. Trials were planted in 4 months by using two species of sweet potato (A) sweet potato cultivars Okinawan (Ipomoea batatasvar.batatas), and (B) Native sweet potato (IpomoeabatatasL.Lam.). The result show that yieldof sweet potato (A) was significantly lower than that sweet potato (B). The maximum yield weight was sweet potato (B) in plot 3(0.96 Kg/Tree), using 150 kg of compost fertilizerand the yield weight ofsweet potato(A) show the lowest yield weight in the plot 4(0.27 Kg/Tree), which was the controlplot with natural condition. Thechemicalfertilizer formula (N13-P13-K21) used inthesweet potato cultivation by Hmong hill tribe farmers werelower quantity of K and P, while the amount of N in suchformula used was suitable to the growing needs. However,the studies have also shown that sweet potato is unsuitable for upstream cultivation due to their high uptakeof soil nutrients., which could cause soil deterioration. |
