| Abstract | Currently, in agriculture, irrigation systems have been introduced been introduced to boost yields and mitigate risks from changing weather conditions when cultivating potatoes. Applying fertilizer along with the irrigation system enhances fertilizer efficiency, elevates yield, and improves quality. However, there is not yet a recommended frequency for fertilizing along with water irrigation. Therefore, an experiment was conducted using a randomized complete block design (RCB) with four replications and five treatments as 1. Apply Fertilize beside row 2. ½ rate beside the row and ½ with fertigation (1 time) 3. ½ rate beside the row and ½ with fertigation (2 time) 4. ½ rate beside the row and ½ with fertigation (3 time) 5. ½ rate beside the row and ½ with fertigation (4 time). Chemical fertilizer rate recommended rate based on soil analysis. Results showed that applying fertilizer at half the recommended rate as basal dressing and half divided into two applications through the irrigation system (Tr 3) Cassava has a high yield of 8.6 tons per rai. |
