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 Resources and infrastructure in poultry farming in Matanao, Davao del SurAlquisar, Rose Anne T. (Davao del Sur State College, 2024-05)The main focus of the study was to determine the resources and infrastructure in poultry farming. The study was conducted with 15 registered poultry farming in Matanao, Davao del Sur. The result disclosed that majority of the respondents aged 41-60 years old, males, married. The result implied that in the poultry production type, it is evident that all 15 respondents are engaged in broilers/meat production and the number of years in poultry farming, the distribution is notable for its concentration in the 8 to 10 years range, with half of the respondents falling within this category. The resources and infrastructure of the poultry farming has no significant difference between the business profile in terms of a number of farmer, thus the null hypothesis was accepted. The substantial majority (86%) rely on loans, and a smaller portion (13%) access credit through cooperatives and 93.3% of respondents reporting this as their primary source of financial support. In terms of the types of feeds used, the data indicate that all respondent (100%) rely on commercially feeds and (100%) relies on water for their poultry farming operations and the duration of water testing, all respondents, again represented by a frequency of 15 and a percentage of 100%, conducted tests for a fixed period of 1 hour only and regarding the available mode of transport, it is noteworthy that all respondents, exclusively rely on open trucks for poultry transportation.Item Development of fishpond automated fish feeder system prototype with GSM notificationEnanoria, Janea Rose L. (Davao del Sur State College, 2024)Fish farmers rely on agriculture as their primary source of income, so they are looking for ways to produce higher quality of fish. Effective methods can help produce a lot of aquaculture products. The study aimed to develop a fishpond automated fish feeder system prototype with GSM notification for adult tilapia fish, addressing the persistent challenges of inconsistent feeding and insufficient awareness of water conditions. The system successfully monitors the status of water, including pH using the pH sensor and water temperature using the water temperature sensor, it also monitors the feed level in the tank using ultrasonic sensor and the time of feeding using real-time-clock (RTC). The study made it ideal for fish farmers. This reveals that using the prototype greatly enhances the agriculture field's performance, enabling the fish farmers to maintain stable growing conditions and the growth of their tilapia fish, as well as the successful sending of the readings from the sensor through SMS notification. Above all, the implementation of the fishpond automated fish feeder system prototype with GSM notification was successful in providing a convenient way for fish farmers to monitor their fish.Item Cost-efficacy of seaweed-based liquid biostimulant as pre-treatment prior to outplanting of Kappaphycus alvareziiMarquez, Kathleen Jane Z. (Davao del Sur State College, 2024-05)This experimental study determined the cost-efficacy of using seaweed-based liquid biostimulant (SLB) as a pre-treatment prior to outplanting Kappaphycus alvarazii and it was conducted at Sitio Biao, Barangay Cogon, Digos City, Province of Davao del Sur, Philippines. Five different levels of treatments were used; control farmers practices (T1), 9g of Urea Inorganic Fertilizer (T2), 10 ml seaweed-based liquid biostimulant (T3), 20 ml seaweed-based liquid biostimulant (T4), and 30 ml seaweed-based liquid biostimulant (T5). Four replications were done in each treatment and all were places randomly in farming site. The yield and specific growth rate (SGR) were recorded and the cost-efficacy of each treatment was analyzed. After 30 days of cultivation, a significant increase in the yield and growth rate were observed in all the treatments. Result also shows that as SLB increases its dosage, the yield and SGR of the Kappaphycus alvarezii after 30 days also increases. The cost-benefit ratios (CBR) of the five treatments in this study was also calculated. T3, T4 and T5 stood out as both portrayed a positive return on investment, at 1.01, 1.27 and 1.42 respectively.Item Growth and yield of lettuce under Kratky hydroponics using coco peat mixed with charcoal and oyster shell as growing mediaCañedo, 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).Item Estimation of potato (Solanum tuberosum) evapotranspiration using blaney-criddle method in Sitio Gagpang, Brgy. Alegre, Bansalan, Davao del SurDico, Joshua Cedrick (Davao del Sur State College, 2024-01)This research study aimed to estimate potato (Solanum tuberosum) evapotranspiration using the Blaney-Criddle method in Sitio Gagpang, Brgy. Alegre, Bansalan, Davao del Sur. The study collected temperature data from February to April 2022 and computed the reference evapotranspiration (ETo) and crop evapotranspiration (ETc) across different growth stages of the potato crop. Results show that the mean monthly temperature in the study area is suitable for potato planting, falling within the range of 15 to 20 C. The study also found that potato plants require significant water, and the computed ETo values of 5 mm/day, 4.98 mm/day, and 5.1 mm/day were within the range of water requirements for potato cultivation. Furthermore, the ETc of the potato crop varied across its growth stages, with the highest ETc in the reproductive stage. The findings can guide farmers in managing their irrigation practices and maximizing crop yields. Future studies may continue the investigation to the months beyond April or explore other irrigation systems that could be implemented in the study area. Overall, this study provides valuable information on potato crop evapotranspiration rates in Sitio Gagpang, Brgy. Alegre, Bansalan, Davao del Sur, and can aid in improving potato farming practices in the study area.Item Nutritional and sensory attributes of banana coffee produced from cavendish banana (Musa cavendishii) flesh at different maturity stageItang, Kris Caresza Kate C. (Davao del Sur State College, 2024-06)This study was conducted to utilized and process rejected cavendish banana fruits into coffee. Sensory evaluation (Aroma, Texture, Color, and General Acceptability), Nutritional Analysis (Protein, Fat, Fiber, Ash, and carbohydrates), and Microbial Analysis in terms of bacterial and fungi count were performed to assess the quality and characteristics of the banana coffee and were analyzed using T-test. In the overall rating, T2 got higher mean rating percentage of Aroma (3.26%), Texture (4.2%), Color (4.106%), and the General Acceptability parameter with 3.36%. For proximate analysis, T1 got higher content percentage in terms of protein (3.742%), Fiber (2.21%), and Ash (5.5%), and T2 for carbohydrates (86.8%) and Fat (5.6%). In microbial analysis, both treatments got equal bacterial count (total plate count) of <1.1 cfu/g however, T2 contained less yeast and molds count (fungi count) of 4.7 x 10 (2) cfu/g present in the composite sample. Based on the T-test result, only aroma difference was not statistically significant while texture, color, and general acceptability showed significant difference. Hence, this study still needs more modification in order to enhance the quality of processing cavendish banana into coffee.Item Marketing strtategy of small-scale food business in Digos City, Davao del SurYana, Rica C.

Cruz, Davao del SurAdo, Mariel Abe (Davao del Sur State College, 2024-05)The purpose of this research was to determine the indigenous farming practices of IP's in selected Barangays of Sta. Cruz, Davao del Sur using descriptive analysis. Most indigenous farmers were middle-aged, between the ages of 36 and 50 years old, no formal Education and with small family size, and are generally Bagobo-Tagabawa. Most of them are farmers who are married. They own a marginal-sized farm, and have been farming despite of the lack of training. The majority of indigenous farmers practiced "kammet" or deforestation, in which this activity is done by clearing tall trees and using tools that are made by indigenous peoples. By following these pre-planting practices, farmers were able to make their work less strenuous. In addition, "Bagobo-Tagabawa" is well-known for its root crops and fruit-bearing trees, which give farmers something to eat while they wait for their harvest .Multiple cropping is a traditional indigenous agricultural technique. Some farmers use organic manure, just like animal manure, twigs, and leaves. Farmers also stick to their traditional farming methods, they use sanggot to get rid of weeds. Before they harvest crops, there is a feast known as "Anig" this indigenous practice is typically done to thank God for their bountiful harvest. Neighbors help one another and give a portion of the harvest as payment in kind rather than cash.Item The value chain analysis of vegetables in Bansalan, Davao del SurSollano, 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.
