    Growth performance of pechay ( Brassica chinensis) in the fabricated growing media for hydroponic system using different combinations of dried banana leaves and coconut coir
    Orbita, Fernando M., Jr. (Davao del Sur State College, 2024-05)
    Hydroponics is a practice that involves plant propagation in a nutrient-filled solution rather than soil, it is an agricultural approach for producing more with less. Growing media is important for seed germination, seedling development, and seedling growth. However, production cost is rather expensive due to the higher cost of commercially available growing media. This study entitled, "Growth Performance of Pechay (Brassica chinensis) in the Fabricated Growing Media for Hydroponic System Using Different Combinations of Dried Banana Leaves and Coconut Coir" was conducted utilizing banana leaves and coco coir as a potential growing media for pechay in a hydroponic system. The study was carried-out using a Completely Randomized Design (CRD) with four (4) treatments replicated three (3) times. T1 (control-hydroponic foam), T2 (25% coco coir and 75% banana leaves), T3 (50% coco coir and 50% banana leaves), and T4 (75% coco coir and 25% banana leaves). The data gathered were evaluated with One-Way Analysis of Variance at the level of 5%, and the least significant difference (LSD) test was additionally utilized to determine the difference between treatments. The results revealed that there was a significant difference in terms of bulk density with a P-value of 0.0000, and in terms of yield of T2 in the yield of T1 and T3 with a P-value of 0.0191. It also revealed that the treatments had no significant difference in terms of water holding capacity, length of roots, plant height, and number of leaves with a P-value of 0.2681, 0.2075, 0.0948, and 0.0692 respectively. The results of the cost per unit production showed that the prices of the fabricated growing media were much lower than the hydroponic foam. Supported by the result of the benefit/cost ratio, it was revealed that utilizing T3 as a growing media for pechay could be beneficial since it has a higher BCR than Treatment 1. This concluded that the fabricated growing media with a balanced concentration of banana leaves and coco coir could be on par with the commercialized hydroponic foam.

    The influence of coco peat and coco coir media on germination of lettuce using hydroponic
    Bastida, Inna Mae (Davao del Sur State College, 2024-05)
    The study able to determine the germination of lettuce under SNAP hydroponics nutrient solution. Using different mixture of treatment and nutrient solution. The root length, plant height, number of leaves, germination rate, and water pH were determined. The data was gathered using a Randomized Complete Block Design. The result that root length average range 4.3-5.1 cm. While plant height average range 3.5-8.2 cm. In number of leaves average range 2.4-3 pcs. Germination rate average range 7.3-7.4. There's no significant difference in terms of root length, plant height, number of leaves and germination rate of lettuce.

    Water consumption and growth of pechay in Kratky method at different depth level of nutrient solution under shaded condition
    Canon, Kirby S. (Davao del Sur State College, 2024-05)
    Green crops are currently cultivated using a hydroponic method. However, the production cost is quite expensive due to the higher cost of commercial nutrient solutions. The purpose of the thesis study was to explore the possibility of reducing the quantity of nutrient solutions and their impact on the growth of pechay. The study was carried out using a Completely Randomized Design (CRD) with three treatments replicated three times. T1 (2 inches depth), T2 (3 inches depth), and T3 (4 inches depth). The collected data were analyzed using a One-Way Analysis of Variance (ANOVA) at a significance level of 5%. The Least Significant Difference (LSD) test was employed to ascertain the variations between the different treatments. The analysis indicated that the treatments revealed significantly varied in root length with a P-value of 0.0010. Further, the analysis indicates that there is no statistically significant difference in terms of mean daily water consumption, plant height, number of leaves, breadth of leaves, plant yield, mean daily difference temperature nutrient solution, and mean daily difference pH level, as indicated with P-values of 0.03272, 0.3787, 0.4376, 0.3787, 0.0727, 0.2997, and 0.4029 respectively.
