    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.

    Growth and yield of lettuce under Kratky hydroponics using coco peat mixed with charcoal and oyster shell as growing media
    Cañedo, Ranel A. (Davao del Sur State College, 2024-06)
    A study was conducted in March in sitio Balutakay Managa, Bansalan, Davao del Sur to investigate the growth and yield of lettuce using Kratky hydroponics. The growing media consisted of cocopeat mixed with charcoal and oyster shell. This study employed a Completely Randomized Design (CRD) consisting of three (3) treatments and five (5) replications. Specifically, the purpose of this research was to identify the growth and yield of lettuce under Kratky hydroponics using cocopeat mixed with charcoal and oyster shell as growing media in terms of plant height, number of leaves, root length and yield. In terms of plant height, treatment 1 (87.5% (266 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest mean height with (20.240 cm) while treatment 2 (82.5% (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the lowest mean height with 19.508 cm. In number of leaves, treatment 1 (87.5% (266 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest number of leaves with (14,000 cm). In root length, treatment 2 (82.5%), (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the highest mean root length with (20.624 cm) while treatment 3 (77.5%) 5.6 g) cocopeat, 7.5% (22.8 g) charcoal, 5% (15.2 g) oyster shell) had the highest mean plant yield with (0.121 kg) while treatment 2 (82.5%), (250.8 g) cocopeat, 7.5% (22.8 g) charcoal, 10% (30.4 g) oyster shell) had the lowest mean of (0.109 kg).

    The value chain analysis of vegetables in Bansalan, Davao del Sur
    Sollano, John Doery L. (Davao del Sur State College, 2024-06)
    Several studies have shown that vegetables have high market potential and contribute substantially to household incomes and nutrition, The resurgence of vegetables' importance in human nutrition is accompanied by a need to understand the interactions among various actors in their value chain to determine ways to add value to produce and improve marketing efficiency. However, the study was conducted to determine the value chain analysis of vegetables by identifying the factors of value chain and the constraints that the vegetables farmers experienced by the vegetables farmers, the study was conducted in Bansalan, Davao del Sur but conduces only on 5 major contribute of common 5 vegetables products that consider as highest major contributor on income where as; Alegre, Balutakay, Bonifacio, Sto. Nino and Darapuay and for the vegetables where as Cabbage, carrot, bell pepper, tomato and raddish. Majority of the respondents were males, married, fall under the age gap of 31-45 years old with a high school level of educational attainment, and had a experience in farming of 11 years and above also had a income generated of 11,000-15,000. The highest mean scores, with a rating of 4.87, suggest that demand and sales analyses are frequently emphasized in the value chain analysis within the community of vegetable farmers. The demand analysis registering at 4.95 of the vegetables value chain, that the quantity of purchases is consistently very high. The highest mean rating, at 4.92, signifies that the selling price is clear and frequently noticed in the process of selling vegetables. The constraints such as credit issues, shortages of required chemicals, government policies, and intense competition with unlicensed traders are commonly observed in the vegetables value chain with a highest mean of 4.44.
