Abstract:
In the Rainforest of South caste "new vnrietks ed sweet potatoes (Ipomea

lower weed density than Umuspo 3. There was no interaction between the fertilizer combinations
and variety, suggesting that the orange-Heshed sweet potato varieties responded similarly to
nutrient management strategics
