Growth and Yield of Sweet Potato (Ipomea batatas) Applied with Different Levels of NPK under Siasi, Sulu Condition

Abstract

The study was conducted to determine the growth and yield of sweet potatoes applied with different levels of complete fertilizer (NPK). It aimed to determine which varying amounts of the complete fertilizer would give the highest expected results. This study was conducted in an area of 875 square meters located at Tulling, Siasi, Sulu. Each treatment was replicated four times to fit a randomized complete block design (RCBD). It was observed that there was a significant difference among treatment means. The findings indicated that complete fertilizer (NPK) at the rate of 45kgs/ha produced the highest yield and gave better growth performance compared to 35kgs/ha and 25kgs/ha. NPK enhances the growth and increases the yield of sweet potatoes. Proper care and management should also be strictly observed to prevent intervening variables from adversely affecting the growth and yield of sweet potatoes.
