A comparative study on the effectiveness of nature farming and conventional farming technologies on the growth and yield of Dapit-saka rice selection
(Central Philippine University, 2007-10)
The agronomic characteristics and yield of Dapit Saka rice selection grown using the conventional farming and nature farming methods were compared and the effect of the different nature farming concoctions against rice pests and natural enemies were evaluated from November 2002 to February 2003 in Bongco, Pototan, Iloilo. Results revealed that rice whorl maggots (Hydrellia philippina), white leafhoppers (Cofana spectra), green leafhoppers (Nephotettix virescens), brown planthopper (Nilaparvata lugens), rice stemborers (Scirpophaga innotata) and grasshoppers (Oxya hyla intricata) were found feeding on rice. Natural enemies observed included a mirid bug (Cyrtorhinus lividipennis), lady beetle (Micraspis crocea), damselfly (Agriocnemis spp.), ground beetle (Ophionea nigrofasciata), vespid wasp and spiders (Lynx spiders, Oxyopes spp.; dwarf spider, Atypena formosana; Orb spider, Argiope catenulata; and long-jawed spider, Tetragnatha maxillosa). It was noted that the use of nature farming technology and the absence of pesticides in the control resulted in more natural enemies. However, plants grown in conventional farming were significantly taller, had the most number of tillers, and heaviest panicles. These resulted in the highest grain yield of 3,466 kg/ha, a net income of P19,643.00 and an ROI of 130.80 % . These values exceeded those of plants in the nature farming technology by 1,641 kg/ha, P 5,612.65 and 25.80%, respectively....

Adaptability and horticultural characterization of different moringa accessions in Central Philippines
(International Society for Horticultural Science, 2017-05-29)
Eighteen moringa accessions from AVRDC - The World Vegetable Center were evaluated for their adaptability and horticultural characteristics in an observational trial at Central Philippine University, Iloilo City, Philippines from June 2009 to May 2012. The accessions originated from India, Laos, Philippines, Taiwan, Tanzania, Thailand and USA. Eight accessions had 100% germination, another eight had 80% while two accessions from Thailand had only 40% germination. All seeds that germinated developed into healthy seedlings with 75 to 100% survival. At 28 weeks after second pruning, accessions Mo-2 (USA) and Mo-40 (India) were the tallest whereas Mo-34 (India) was the shortest. Mean stem diameter ranged from 3.5 (Mo-34) to 8.5 cm (Mo-4, Thailand). Mo-38 (Thailand) had the most branches, whereas Mo-33 (Philippines) had the least. Two accessions from Thailand (Mo-4 and Mo-14) had the highest leaf fresh weight. However, Mo-6 (Thailand) produced the highest percent dry matter. Of the 18 accessions, only 11 developed flowers which started to appear 49 to 93 days after transplanting (DAT). Of these 11 accessions, only 9 produced pods which developed from 75 to 182 DAT. Mo-3 (Taiwan) developed the most pods but Mo-34 produced the most seeds one year after planting. Three years after planting, all the accessions except Mo-4 and Mo-6 developed flowers, pods and seeds with Mo-38 producing the most seeds per pod and Mo-15 having the most seeds per tree. Red mites (Tetranychus urticae), defoliators, leaf-footed bug (Leptoglossus phyllopus) and whiteflies (Bemisia sp.) were present in the field but caused only minor damage to plants. Stem rot was the only pathogenic disease observed. These results indicate that Mo-4 and Mo-14 are ideal for fresh leaves whereas Mo-2 and Mo-6 are ideal for dry matter production. Furthermore, Mo-15, Mo-7, Mo-9 and Mo-34 are desirable accessions for seed production....
A study on the nutritional quality of Moringa oleifera and Moringa peregrina
(International Society for Horticultural Science, 2021-04-15)
A study was conducted to determine and compare the growth characteristics and nutritional quality of M. oleifera and M. peregrina. Three moringa cultivars consisting of two M. oleifera cultivars (‘PKM-1’ and ‘Local’) and one M. peregrina cultivar were evaluated in pot experiments using a randomized complete block design with four replications. Pruning and sampling of leaves for biomass yield and nutritional quality analysis were performed when plants attained a height of 1 m. Young and fully expanded green leaves were sampled for nutritional analysis and biochemical components. Results showed that plant height and number of leaves differed significantly between the three cultivars. ‘PKM-1’ and the ‘Local’ cultivar were taller than M. peregrina, whereas, ‘PKM-1’ and M. peregrina produced a higher number of leaves than the ‘Local’ cultivar. There were no significant differences in the number of side branches among cultivars. Although there were no significant differences in leaf fresh weight among cultivars, M. peregrina and ‘PKM-1’ had a tendency of higher leaf fresh weight than the ‘Local’ cultivar. Both cultivars had significantly higher dry leaf biomass than the ‘Local’ cultivar. Significant differences in calcium, iron and anti-oxidant activity were found between the three cultivars. ‘PKM-1’ contained higher calcium than M. peregrina and the ‘Local’ cultivar. ‘PKM-1’ also contained higher iron than M. peregrina, but not significant compared to the ‘Local’ cultivar. Both ‘PKM-1’ and M. peregrina had significantly higher anti-oxidant activity than the ‘Local’ cultivar. Significant differences were also observed in nitrogen free extract, crude protein and crude fat. Nitrogen free extract content was higher in M. peregrina than in ‘PKM-1’ and ‘Local’ cultivar. The ‘Local’ cultivar contained higher crude fat than ‘PKM-1’ and M. peregrina. This study indicated that moringa cultivars differ in growth characteristics, selected nutritional qualities and biochemical components. Further studies should investigate and determine other nutritional qualities that are not covered including vitamins, amino acids and important anti-oxidants....
Moringa research and development project at Central Philippine University: Progress, challenges and opportunities
(International Society for Horticultural Science, 2021-04-15)
Moringa is a common backyard tree crop in the Philippines and is grown by many home owners as a source of green leafy vegetable. Although moringa is a popular crop, little research studies have been conducted in central Philippines. The College of Agriculture, Resources and Environmental Sciences at Central Philippine University initiated a research project in 2009 to: 1) identify and evaluate promising cultivars of moringa adapted to the growing conditions of Western Visayas and 2) develop improved crop management practices for increasing yield and production. Germplasm collection and evaluation identified promising cultivars with desirable horticultural characteristics from India, Laos, Philippines, Taiwan, Thailand and USA. From this field evaluation one promising cultivar, 'PKM-1' from India, was grown at four plant densities to determine leaf biomass production as influenced by plant density and harvest frequency. Maximum plant density of 40,000 plants ha<sup>-1</sup> and harvest frequency of 8 week intervals produced a high leaf biomass yield. A separate study was conducted to determine and compare the nutritional quality of Moringa oleifera and Moringa peregrina. Significant differences in calcium, iron and anti-oxidant activity were found between the species. Moringa oleifera 'PKM-1' contained higher calcium and iron than M. peregrina. Training workshops and seminars were conducted to transfer the technology and educate farmers on the multiple uses and benefits of moringa. The university has established linkages with the World Vegetable Center (Taiwan), Department of Agriculture and local NGOs in promoting moringa as a high-value crop. The university has proposed to organize a regional R&D center for moringa to address the challenges and opportunities facing moringa growers in areas of improved cultivars, seed production and propagation, crop management practices, post-harvest processing and quality, marketing and value chain enhancement....

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....
