Abstract:
The study was conducted to determine the best performing potato entry applied with organic fertilizer based on yield and resistance to pest and diseases; determine the kind of organic fertilizer that will produce plants with high yield under La Trinidad, Benguet condition; determine the best combination of organic fertilizer and potato entry that will give the best performance in terms of yield and resistance to pest and diseases; and determine the return on cash expenses (ROCE) on potato production.
Among the four potato entries, Tawid was the most vigorous. Entries Omega, Tawid, and 2.21.6.2 were the most resistant to late blight at 60 DAP. Entries Tawid and 2.21.6.2 were highly resistant to leaf miner. The application of organic fertilizer may have contributed to the resistance of the plants.
Based on marketable yield, entry Tawid produced the highest.Plants applied with
Murasaka produced the highest marketable and total yield. Entry Tawid applied with Murasaka registered the highest return on cash expenses.
Based on the results, entry Tawid could be recommended for organic potato production under La Trinidad, Benguet condition. Application of organic fertilizer is possible for potato production under La Trinidad, Benguet condition.
