Enhancement of professional education in solid waste management in the Philippines
The enhancement of professional education in SWM was through the offering of a 1-year post-baccalaureate degree Diploma in Environmental Resource Management and Technologies major in Solid Waste Management. It officially ...
How to promote a job change of dumpsite waste pickers? Evidence from a field experiment in the Philippines
Switching a waste disposal policy from open dumping to sanitary landfilling requires a job change of waste pickers. We conducted a field experiment at Iloilo in the Philippines which offers dumpsite waste pickers a new job ...
Adaptability and horticultural characterization of Moringa accessions under Central Philippines conditions
(AVRDC – The World Vegetable Center, 2013)
This study was conducted to determine the adaptability and describe the horticultural characteristics of Moringa oleifera Lam. accessions under central Philippines conditions. Eighteen Moringa accessions obtained from AVRDC – The World Vegetable Center were evaluated in observational trials at Central Philippine University, Iloilo City, Philippines in 2009. The accessions originated from India (3), Laos (1), Philippines (1), Taiwan (1), Tanzania (1), Thailand (10), and USA (1). Three-month-old seedlings were transplanted in nonreplicated plots at a spacing of 2 m between rows and 1.5 m between plants. Data were recorded on growth and stand survival, plant height, stem diameter, number of branches, fresh leaf yield, pod and seed production, and incidence of insect pests and diseases. Percentage seed germination ranged from 40 to 100%, with eight accessions having 100% and eight accessions 80% germination. Two accessions from Thailand had poor germination (40%). All seeds that germinated developed into healthy seedlings with 80 to 100% survival. At 28 weeks after second pruning, accessions Mo-2 (USA) and Mo-40 (India) produced the tallest plants (5.6 and 5.1 m, respectively), whereas Mo-34 (India) produced the shortest plants (2.9 m). Mean stem diameter ranged from 3.5 cm (Mo-34) to 8.5 cm (Mo4-Thailand). Mo-38 (Thailand) produced the highest number of branches (5.3), whereas Mo-33 (Philippines) showed the lowest number of branches (2.0) per plant. Two accessions from Thailand resulted in the highest leaf fresh weight, which exceeded 2 kg/plant from two prunings. Eight accessions produced leaf fresh biomass that exceeded 1 kg/plant. Mo-3 (Taiwan) developed the highest number of pods, whereas Mo-34 produced the highest number of seeds. Red mites (Tetranychus urticae), Coccinellid beetles (Coccinellidae), leaf-footed bug (Leptoglossus phyllopus) and whiteflies (Bemisia sp.) were present, but caused only minor damage to plants. Stem rot was the only disease observed in a few plants....
Horticultural characterization of AVRDC moringa germplasm in the Philippines and Taiwan
(International Society for Horticultural Science, 2015-12-06)
The major objective of this study was to evaluate a subset of the AVRDC Moringa oleifera germplasm collection for important horticultural traits in the Philippines and Taiwan. The 18 AVRDC moringa accessions originated from India, Laos, Philippines, Taiwan, Tanzania, Thailand and USA. Three-month-old seedlings were transplanted onto single-row raised beds spaced 1.5 m apart. Plants were arranged in a randomized block design with three replications. Data were collected on plant height, stem diameter, number of branches, canopy width, fresh and dry biomass (stems and leaves), days to flowering, and pod/seed yield. In Taiwan, one month after transplanting four accessions attained a plant height of above 1 m. Number of side branches ranged from 9 to 14 per plant. Differences in plant height and stem diameter were significant at 70 days after transplanting (DAT). Tallest plants (2.9 m) were observed in LSQUOMo-35RSQUO from Tanzania while LSQUOMo-8RSQUO from Thailand produced the largest stem diameter (36 cm). Leaf fresh weight and dry biomass was highest (15.8 and 9.2 t ha<sup>-1</sup>, respectively) for LSQUOMo-35RSQUO at 70 DAT. Survival and stand count decreased after two strong typhoons and severe flooding in 2009 and 2010. In the Philippines, accessions LSQUOMo-2RSQUO (USA) and LSQUOMo-40RSQUO (India) produced the tallest plants 28 weeks after second pruning. Mean stem diameter ranged from 3.5 cm (LSQUOMo-34RSQUO) to 8.5 cm (LSQUOMo-4RSQUO). LSQUOMo-38RSQUO (Thailand) produced the highest number of branches. Two accessions from Thailand (LSQUOMo-4RSQUO and LSQUOMo-14RSQUO) resulted in the highest leaf fresh weight, which exceeded 20 t ha<sup>-1</sup> from two prunings, while LSQUOMo-29RSQUO (India) produced the highest dry leaf biomass. Most accessions tolerated waterlogged conditions with 60-100% plant survival stand count. The results indicate that there are moringa accessions with promising horticultural traits for the high rainfall climate of Southeast Asia....
