    Effect of GREENTEC organic fertilizer on the yield of pechay (Brassica chinensis)
    Macarayan, Olympio B.; Campaner, Alexander M. (Southern Philippines Agri-business and Marine and Aquatic School of Technology, 2004-01)
    This study was conducted in the farmer's field of Barrio Pampanga, Lanang, Davao City from the period February to April 2001. It aimed to generate information on the agronomic effectiveness of 20 bags per hectare GREENTEC organic fertilizer and to evaluate the growth and yield response of pechay to different rates and combinations of GREENTEC organic and inorganic fertilizers. Results showed that growth of pechay in T5 (20 bags per hectare of GREENTEC organic fertilizer alone) was comparable to that in T2 (Ammophous - 3 bags/ha + Ammosul -12 bags/ha + Muriate of Potash-0.5 bags/ha), T3 (Amorphous -11/2 bags/ha + Ammosul - 6 bags/ha + Muriate of Potash - 0.5 bag/ha; T4 (T3 + T5) and T6 (T2 + T5) but much higher compared to T1 (no fertilizer). The yield of pechay in T5 was comparable to that of T2 and T3 but significantly higher compared to the yield of pechay in T1. By mixing 20 bags GREENTEC organic fertilizer per hectare with inorganic fertilizer rates in T2 and T3, highly significant increase in yield of pechay was observed (T6 and T4).

    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).

    Severity of bacterial leaf blight disease and yield of PSBRc72H (Mestizo1) as influenced by cultural practices
    Agudera, 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.

    Cardaba production
    Campaner, 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.
