    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.

    Identifying suitable sites for pump irrigation system from open source and shallow tube well in selected areas of Davao Del Sur through geographic information system-based water resources assessment
    Trondillo, M. J. F.; Generallao, I. C .; Valleser, R. A. R.; Lopez, M. T.; Janson, A. Z., Jr.; Bejarasco, J. A.; Toriales, I. R., Jr. (2019-05)
    This paper features the Geographic Information System (GIS) in identifying suitable sites for small scale irrigation projects (SSIP) particularly pump irrigation system from open source (PISOs) and shallow tube well (STW) through water resource assessment. The development of GIS-based assessment model for SSIP and resource map in aid of SSIP planning and development is limited in some municipalities. To develop a reliable GIS-base framework, the ArcGIS tool and spatial method was used in compiling specific factors with field analysis and developing regional resource map for SSIP. The results showed that STW in Digos City and Municipality of Hagonoy is 117 units and 17 units respectively. The average water depth in existing STW is within the 6.5 meters with capacity to irrigate 3 to 5 hectares per unit, low investment with high water use efficiency and simple to operate. It was found out that most STW is provided by Department of Agriculture-Regional Field Office XI and Local Government Units. The STW is suitable for Digos City with an area of 379.32 hectares. While the PISOS were identified with different range of pump horsepower. There are 10 units of PISOS in Digos City and 15 units in Hagonoy mostly provided by National Irrigation Administration-XI. It was found out that in Digos City the 1,855.53 hectares are highly suitable and 14,377.55 hectares are not suitable for PISOS. The results of this study may assist the decision making processes for planning and development of SSIP using the developed protocol and tools for different purpose in agricultural production in Davao del Sur, Region XI and the whole country.
