Abstract
This study aimed to determine the most effective agricultural substrate such as 100% coco coir, 50% coco coir + 50% pumice, and 50% coco coir and 50% hydroton used in the production of bell pepper in automatic gravity-fed watering system. The study was conducted from March to May 2019 at LWRMC Farm, Central Luzon State University, Science City of Muñoz, Nueva Ecija. The study was analyzed using the Complete Randomized Design (CRD) and the Least Significant Difference (LSD) was used for the comparison among means. The study used low cost materials that were readily available in the market and constructed according to plan and their measurements. The performance evaluation of the system that affects due to different levels of compaction. Clarabel F1 was the variety of bell pepper used in the study the maximum height of bell pepper was 32.22cm. Results showed that the bell pepper planted in the 50% coco coir + 50% hydroton had the highest reading recorded among the three treatments in terms of height, number of leaves and number of nodes. Larger pore spaces mean better percolation, and some air holding capacity to keep root zone oxygenated this was the advantages of hydroton that made the 50% coco coir and 50% hydroton have the most successful treatment among the other. The initial investment on automatic gravity-fed calculated Php 14,296.70.
