Abstract
This study compares the effect of Hog Waste Organic Fertilizer (HWOF) and Commercial Inorganic Fertilizer (CIF) on the growth performance of pechay (Brassica rapa) in 7 Treatments: T1- pure soil; T2 - soil with CIF; T3- 20% hog waste; T4 - 40% hog waste; T5 - 60% hog waste; T6 - 80% hog waste; T7 – 100% hog waste. The experiment for 30 days was performed on a randomized complete block design (RCBD). The data gathered were analyzed using one-way ANOVA to determine the differences among the growth performances of pechay based on height, leaf width, no. of leaves, weight, and root length. The results present the physico-chemical analyses of both soil and hog waste fertilizers. Regarding the growth performances of pechay (Brassica rapa), T5 obtained the highest plant height - 108.27 cm and leaf width – 112.07 cm, which were significantly higher than T2 using CIF. The highest weight gain was obtained by T6, which was significantly higher than the other treatments followed by T5, but both were comparable to the samples of CIF, while T3 obtained the longest root length. Thus, the application of 60% to 80% HWOF yields comparable results with CIF. Hence, such application is recommended for community organic farming.
Highlights
Livestock production continues to be an essential part of the global agricultural system as meat consumption worldwide continues to rise [1]
Organic fertilizers produced from hog manure, Universal Journal of Agricultural Research 9(6): 248-257, 2021 yield benefits as they are rich in essential nutrients, such as Nitrogen and Phosphorous, which are required by the soil and necessary for plant growth [2]

Summary
Livestock production continues to be an essential part of the global agricultural system as meat consumption worldwide continues to rise [1]. In the Philippines, 80% of the total livestock production has been accounted from the swine industry [3]. Such a case has been observed in other parts of the world in Canada [4]. Rather than disposing of hog waste, studies have revealed that it may be utilized as an organic fertilizer [5], [6]. Organic fertilizers produced from hog manure, Universal Journal of Agricultural Research 9(6): 248-257, 2021 yield benefits as they are rich in essential nutrients, such as Nitrogen and Phosphorous, which are required by the soil and necessary for plant growth [2]. The study of [5] found that when applying hog manure on hybrid poplars, it has significantly increased their growth and helped improve the chemistry of the soil
