Item Kappaphycus dripping enhance seed germination and production of hybrid rice (PSBRc72H – Mestizo 1)Agudera, Juan P., Jr.; Caballero, Graciela L.; Revilla, Nila Nanette S.; Gliocam, Mariz (Southern Philippines Agri-Business and Marine and Aquatic School of Technology, 2013)This study was conducted in SPAMAST-CAS, Matti, Digos City and at New Ilocos, Magsaysay, Davao del Sur. The general objective of the study was to evaluate the germination, growth and yield of PSBRc72H as influenced by different levels of Kappaphycus Drippings (KD). Findings of the study revealed that hybrid rice seeds soaked for 12 hours with 20 ml of KD per liter of water enhanced germination to 86.67%. KD as foliar fertilizer improved the agronomic characteristics such as plant height in cm (45 DAT), number of tillers per hill (60 DAT) and number of productive tiller per hill; and yield components such as number of filled spikelets per panicle and 1,000 seed weight (g) thereby increasing the grain yield (t/ha) of hybrid rice. KD did not influence the length of panicle (cm).Item Distribution and ecology of metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 in Mindanao, PhilippinesPatano, Romeo R., Jr.; Mohagan, Alma B.; Ponce, Amy G.; Guiang, Maria Melanie M.; Malinao, Rodceal; Pescuela, Gretl Rae P.; Coritico, Fulgent P. (Department of Science and Technology, 2023-02)Metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 is a Mindanao-endemic species known only in Davao del Sur. Here, we recorded the species first in Bukidnon and the Cotabato region. Moreover, we also provide ecological notes of the species specifically the identities of its food plants, description of its habitat, and potential threats.Item Severity of bacterial leaf blight disease and yield of PSBRc72H (Mestizo1) as influenced by cultural practicesAgudera, Juan P., Jr.; Capili, Lolito N. (Southern Philippines Agri-Business and Marine and Aquatic School of Technology, 2013)A study on the severity of bacterial leaf blight disease (Xanthomonas oryzaepv. oryzae) and yield of PSBRc72H (Mestizo 1) as influenced by cultural practices was conducted at the Central Mindanao University Agricultural Experiment Station (AES), University Town, Musuan, Bukidnon from July- November 2006 to identify combinations of different cultural practices that could provide conditions unfavorable to bacterial leaf blight disease, their effects on the yield and agronomic characteristics; and correlate the different cultural practices, agronomic characteristics, yield components, severity of bacterial leaf blight the yield. The applications of controlled irrigation practices such as applied once a week, saturated and intermittent, any of the four NPK rates (80- 60-120, 100-60-120, 80-80-140 and 100-80-140) and planting at wider distances (20 cm x 30 cm and 30 cm x 30 cm) provided conditions unfavorable to bacterial leaf blight disease. Yield was higher if applied with continuous irrigation and planted 20 cm x 20 cm and 20 cm x 30 cm than applied with controlled irrigation which was intermittent, saturated and once a week and planted at wider distance (30 x 30 cm). Applications of any of the four NPK rates (80-60-120, 100-60-120, 80-80-140 and 100-80-140) did not affect the yield. Bacterial leaf blight disease accounted 33.49%; cultural practices 10.29 %; the agronomic characteristics 40.87%; and the yield components 8.78% respectively, on the variation in yield.Item Performance of corn (Zea may Linn.) to the application of mudpress-based organic fertilizerMacarayan, Olympio B.; Campaner, Alexander M.; Mercado, Marcelina Fe G.; Fuentes, Augie E.; Revilla, Nila Nanette S. (Southern Philippines Agri-Business and Marine and Aquatic School of Technology, 2013)The developed mudpress-based organic fertilizer (MBOF) had been tested to corn following the Fertilizer and Pesticide (FPA) protocol. The trial was conducted in Brgy. Dulangan, Digos City. Corn ear length and number of corn ears per plant were not affected by the fertilizer application. However, plant height, ear diameter, fresh weight of corn ear, dried weight of corn ear, weight of kernel after drying and computed yield were significantly improved by the application of inorganic and MBOF or their combinations. Positive response of corn was noted among these variables, thus, MBOF can be utilized as an ideal organic fertilizer.Item Cardaba productionCampaner, Alexander M.; Estimada, Geronima M.; Bayaron, Teresita B.; Labasano, Susana T.; Bontia, Lynette A.; Salibay, Ma. Asuncion L.; Melencion, Ralf O. (Southern Philippines Agribusiness and Marine and Aquatic School of Technology, 2008)PREFACE There is a general recognition in the Philippines and in Region XI of the importance of an appropriate cardaba banana farming for better yield and higher farm income. Appropriate production practices for cardaba crop is a basic requirement in sustaining cardaba farming. The important criteria of good, sound and appropriate cardaba production practices include good irrigation and drainage, maintained farm hygiene and soil fertility, timeliness of pest, diseases control, proper fruit care and handling and population control. Cardaba production is an important component in a coconut farming system as an intercrop. Also, it is grown in backyard/small scale, yet, its agribusiness potential is enormous. Good, sound and appropriate management for better production and higher farm income is the framework provided in the pamphlet. The authors wish to express their appreciation to the Commis[s]ion on Higher Education for funding the reproduction of this pamphlet as an important contribution towards the development and sustenance of cardaba in the country's agribusiness sector.Item Enhancing herbage growth, yield and quality of stevia (Stevia rebaudiana bertoni) using bio-organic nutrients in varied soil mediaCalapardo, Mara Jean Marielle; Manigo, Bryl I. (Penerbit Universiti Kebangsaan Malaysia, 2024)The present method of stevia propagation is still insufficient to meet its increasing demand. Moreover, the use of organic inputs as substitutes for inorganic fertilizers to improve soil quality and productivity is also desired. In this study, the effects of bio-organic nutrients and different growing media compositions on Stevia’s herbage growth, yield and quality were determined. A completely randomized design was used with 20 rooted stem cuttings per replication at one cutting per potting bag, laid in a 4 × 4 factorial arrangement. Growing Media (garden soil alone [GS]; GS + rice hull [RH]; GS + vermicompost [VC]; and GS+RH+VC) served as factor A while bio-organic nutrients (fermented fruit juice [FFJ]; vermi tea [VT]; seaweed tea [ST] and control) as factor B. There were 16 treatment combinations replicated four times. Results showed that GS+RH+VC consistently improved the survival rate, plant height, leaf and shoot count per plant, weight (fresh and dry), and herbage yield of Stevia. Furthermore, VT boosted the herbage yield and visual quality. In terms of interaction effects, plants grown in garden soil mixed with vermicompost (GS+VC) with VT application developed more leaves than other treatment combinations. Hence, these bio-nutrients and growing media composition significantly enhanced the production of Stevia.
