    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).

    Distribution and ecology of metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 in Mindanao, Philippines
    Patano, 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.

    Enhancing herbage growth, yield and quality of stevia (Stevia rebaudiana bertoni) using bio-organic nutrients in varied soil media
    Calapardo, 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.
