Growth and Yield of Potato as Affected by the Different Rates of Alnus Compost Enriched with Processed Chicken Manure in Balili, La Trinidad Benguet

Abstract

The study was conducted to determine the growth and yield of potato (cv. Gloria) applied with different rates of Alnus compost enriched with processed chicken manure; determine the best rate of Alnus compost enriched with processed chicken manure on the growth and yield of potato (cv. Gloria); and to determine the profitability of using Alnus compost enriched with processed chicken manure on potato production. The different rates of Alnus compost enriched with processed chicken manure applied on the potato plants showed no significant effect on plant height, plant vigor, leaf miner infestation and potato late blight infection. Significant effect was shown on the number and weight of marketable tubers. Application of 15kg of Alnus compost plus 5kg of processed chicken manure produced the highest number of marketable tubers and gave the heaviest total yield. Highest ROCE was obtained from potato plants applied with 5kg Alnus compost plus 5kg of processed chicken manure.
