Item Growth and yield performance of loose-leaf lettuce (Lactuca sativa) under greenhouse condition using different levels of ventilation in Barangay Kapatagan, Digos City, Davao del SurRagomio, Ranel Q. (Davao del Sur State College, 2024-06)The study was conducted to evaluate the growth and yield performance of loose-leaf lettuce (Lactuca sativa) under greenhouse condition using different levels of ventilation in Brgy. Kapatagan, Digos City, Davao del Sur. A Complete Randomized Design was used as the experimental layout of the study with 3 treatments replicated 3 times. The treatments used were as follows: Treatment 1 (T1) = Ambient Airflow, Treatment 2 (T2) = 1 Intake Fan and 1 Exhaust Fan and Treatment 3 (T3) = 2 Intake Fans and 2 Exhaust Fans. It was evaluated during 15th, 30th and 40th day after transplanting. Data were statistically analyzed using Single Factorial Analysis of Variance (ANOVA) and Tukey's test was used to identify treatments that are significantly different from each other. The result on analysis of variance (ANOVA), shows that there were significantly difference among treatments in terms of plant height, number of leaves and yield of loose-leaf lettuce. Tukey's test results, revealed that the plant height of loose-leaf lettuce during 15th day after transplanting T1 and T2, T1 and T3 significantly differ from each other while, T2 and T3 has no significant difference. Result also revealed that on 30th and 40th day after transplanting T1, T2 and T3 has a significant difference from each other. In terms on the number of leaves on 15th and 30th day after transplanting Treatment 1 has significant difference against Treatment 2 and Treatment 3. However, Treatment 2 and Treatment 3 have no significant difference from each other. While on 40th day after transplanting results shows that T1, T2 and T3 has a significance difference to each other. In terms on the yield (g) of loose-leaf lettuce, all treatments show that treatment 3 was observed to be the best experimental treatments in all parameters.Item Processing of fiber based biofoam cups using sugarcane bagasse and cassava starch as plant container for hydroponic systemSarno, Ma. Rachel Anne N. (Davao del Sur State College, 2024-05)The study was designed to produce a fiber-based biofoam cup from different mixtures of sugarcane bagasse and cassava starch, an alternative to styrofoam cups as plant containers in a hydroponics set-up. The study was carried out with 3 treatments replicated thrice. The mixture was added with a constant amount of polyvinyl alcohol, glycerol and magnesium stearate by weight basis, and then coated with paraffin wax. The data for density, water absorption, solubility as well as the performance of the biocups in terms of plant growth (no. of leaves), plant mortality and pH level when used as plant containers in Kratky method were gathered through a completely randomized design and analyzed using the analysis of variance (ANOVA) and the Least Significant Difference (LSD) test at 1% and 5% levels. Only the treatment yielding the best results in terms of quality were evaluated for hydroponic application. Statically, the results indicate that the density and water absorption of the cups from the three treatments significantly varied with a P-value of 0.0055 and 0.0127 respectively. However, no significant difference was observed for the solubility of the biocups among the treatment with a P- value of 0.0827. Based on the results, treatment 3 exhibited the highest density and lowest values for solubility and water absorption among the treatments and was selected with the commercially available styrofoam cups as plant containers in Kratky method hydroponics set-up. For the duration of the observation period, all petchay plants survived resulting in a mortality rate of 0%. Furthermore, there was a significant difference in the number of leaves, as indicated by the P-value of 0.0059 while pH level was found to be lower (6.38) for treatment 3 than the control (6.40). The results suggest that biofoam cups are not best to be used as plant container in hydroponics, but due to its higher density, low water absorption and solubility it implies potential suitability for other planting materials, such as for seedlings.Item Water consumption and growth of spring onion (Allium fistulusom L.) under different nutrient solution depths in kratky hydroponics under shaded conditionsDabalos, Marc Jay P. (Davao del Sur State College, 2024-06)The study was conducted at Davao del Sur State College (DSSC), Brgy. Matti, Digos City, Davao del Sur, to investigate the effect of varying depths of nutrient solution on the water consumption and growth of spring onion. The experiment followed a Completely Randomized Design (CRD) with three treatments and three replications. The treatments were T1 (15cm depth of nutrient solution), T2 (10 cm depth of nutrient solution), T3 (5 cm depth of nutrient solution). The effect of the depths of nutrient solution was determined with regards to the water consumption, plant height, stem diameter, number of leaf, root length, number of shoots per plant and the temperature of nutrient solution. The gathered data was statistically evaluated using analysis of variance (ANOVA) at a significance level of 1% to 5% based on the results of the study, the nutrient solution depths showed no significant effect on the water consumption and growth response of spring onion (Allium fistulusom L.) and also to the nutrient solution temperature.Item Growth performance of pechay ( Brassica chinensis) in the fabricated growing media for hydroponic system using different combinations of dried banana leaves and coconut coirOrbita, 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.Item The influence of coco peat and coco coir media on germination of lettuce using hydroponicBastida, Inna Mae (Davao del Sur State College, 2024-05)The study able to determine the germination of lettuce under SNAP hydroponics nutrient solution.

(Davao del Sur State College, 2024-06)This study investigated the physical characteristics of Tacunan Green Dwarf (TACD) coconuts from a farm in Barangay Harada Butai, Padada, Davao del Sur. The farm spans 4 hectares, with 16-year-old trees grown at an elevation of 18 meters in clay soil. Farming practices involved fertilizer application and intercropping. Key parameters examined include major diameter, minor diameter, intermediate diameter, flesh thickness, shell thickness, geometric mean diameter, sphericity, surface area, fruit weight, shell weight, husk weight, coconut water weight, and flesh weight. A Complete Randomized Design (CRD) was used to evaluate the data using three treatments: Young coconut fruits (Treatment 1), fairly mature coconut fruits (Treatment 2), and mature coconut fruits (Treatment 3). The physical characteristics of young, fairly mature, and mature coconut fruits differ significantly (p < 0.05) according to the results of the Analysis of Variance (ANOVA) test. The mean major diameter (length) decreases as the coconut matures, wherein T1 had the highest value of 130.96 mm. T2 has the highest mean minor diameter of 116.17 mm and intermediate diameter of 117.48 mm. Flesh thickness was highest in T2 with 4.55 mm. The geometric mean diameter, sphericity, and surface area were also highest in T2, with values 119.66 mm, 0.94, and 45281.18 mm2, respectively, indicating optimal size and shape during the fairly mature stage. Weight components varied, with T2 having the highest mean fruit weight of 1075.32 g and water weight of 467.89 g, and T3 the highest flesh weight (384.82 g), while shell and husk weights were highest in T1, having values of 319.36 g and 2268.76 g respectively, and decreased with maturity. This study underscores the significant differences in the physical characteristics of coconut fruit across different maturity stages, providing essential insights into their growth and development patterns.Item Acceptability level of banana (Musa balbisiana) and calamansi (Citrus microcarpa) peels as alternative floorwaxRosit, Khitterine Fel l. (Davao del Sur State College, 2024-03)The objective of the study was to determine the acceptability-level of Davao del Sur State College’s Banana (Musa balbisiana) peels and Calamansi (Citrus microcarpa) peels as alternative floor wax. It was an invention product that could be further recycled into an item of excellent quality that would be valuable to families in terms of appearance, color, odor, slip-resistance and water-resistance. This research comprises five treatments and will have thirty participants. Demonstration of product innovation and a use of complete randomized design and a survey questionnaire with a predetermined rating scale using a Likert Scale of 1.00 to 5.00 was use to collect the data. The results of a descriptive-comparative research approach and analysis of variance (ANOVA) revealed that banana (cardava) and calamansi peels was more acceptable and treatment 3 had the highest mean and verbal description of being the most acceptable and ii valued by the respondents. Therefore, Treatment 3 is the best as it most acceptable than the control group in terms of the sensory characteristics conducted appearance, color, odor, slip-resistance and water-resistance. As a result, it may be improved and adapted for commercialization, thereby rendering it more appealing to buyers. Innovations and development of banana and calamansi peels as alternative floor wax are highly encouraged. It was recommended to use proper and accurate textile or fabric of rag in applying this alternative floor wax, and it was suggested, which is considered a major issue for environmental and green ecology, that this waste is dumped in landfills, contributing to pollution problems and environmental issues. Finding solutions to the world, particularly the Philippines, environmental problems as a result, this is the crucial initial step in resolving it.
