Improving smallholder dry season vegetable production through increased water productivity with low cost drip irrigation technology in Cambodia
(International Society for Horticultural Science, 2011-12-31)
In rainfed cropping systems limited water supply is a major constraint for increased crop production during the dry season. The use of affordable drip irrigation systems can increase crop yield, water use efficiency, and labor productivity in dry season vegetable production. Farmer participatory research was conducted in Cambodia during the 2008 dry season to evaluate the performance and benefits of a low-cost drip irrigation system for improving small-scale vegetable production. The effect of integrating improved soil nutrient management through fertilizer deep placement on crop yield and economic returns were determined for selected vegetable crops. Compared with traditional practice of hand-watering, drip irrigation increased yield of chili (Capsicum annuum), cucumber (Cucumis sativus), and eggplant (Solanum melongena) by almost 50%, but reduced average net income by 25%. Drip irrigation decreased water use by 33%, and increased water use efficiency by 63% and labor productivity by 74%. The use of fertilizer deep placement with drip irrigation resulted in higher yield (18%) compared with commercial NPK fertilizer irrespective of irrigation methods. Significant response was shown in yard-long bean (Vigna unguiculata var. sesquipedales) with 35% yield increase and 50% increase in net income. Under drip irrigation the use of fertilizer deep placement reduced water use by 48%, increased water use efficiency by 70% and labor productivity by 78%. This study demonstrated the potential benefit of low-cost drip irrigation and fertilizer deep placement for improving smallholder vegetable production in Cambodia during the dry season through higher yield, increased water use efficiency, and higher economic returns and labor productivity compared with farmers’ traditional practice of hand-watering and fertilizer application....
Progress in research and development of moringa at the World Vegetable Center
(International Society for Horticultural Science, 2017-05-09)
The World Vegetable Center has a collection of over 50 moringa accessions, majority of which belong to M. oleifera. The planting of this species in southern Taiwan started some 35 years ago. The World Vegetable Center initiated research on moringa in 2001. A small project was established to introduce and evaluate a number of moringa accessions collected from Asia, Africa and USA. The accessions were evaluated for growth characteristics and horticultural traits, aiming at high leaf production and nutritional value. A total of 50 accessions were collected and from this collection, seeds of 42 accessions representing four species (Moringa oleifera, M. stenopetala, M. drouhardii and M. peregrina) were germinated and transplanted to the field for seed multiplication, characterization and evaluation. Twenty-two accessions produced sufficient seeds for replicated evaluation trials and seed distribution. Ten promising accessions were selected and evaluated in replicated trials over a two-year period. Among those, three accessions showed fresh young shoot yield averaging 20-40 t ha<sup>-1</sup>. The effects of leaf type (age), harvest season and variety on nutrient content were investigated as a component of this study. Results showed no significant differences for most nutrient contents among accessions. Mature leaves are more nutritious than young leaves or shoots. Nutrient content varied with harvest season. Calcium, vitamins A and E were higher in hot-wet season in southern Taiwan than during winter, whereas Fe and vitamin C were higher in cool-dry season than in summer. Subsequent field evaluation studies revealed the variability of Moringa accessions in terms of horticultural traits. The accessions varied significantly in plant height, stem diameter, leaf and stem biomass, number of side shoots, tolerance to flooding and survival after heavy rainfall and strong wind brought about by tropical typhoons. Superior and promising accessions are being multiplied to meet the increasing demand for seed and planting materials of moringa. During the last ten years, the World Vegetable Center has distributed moringa germplasm to universities, government organizations, non-governmental organizations and private companies in 15 countries. The Philippines, Malaysia, Thailand, Germany, Vietnam, Egypt, The Netherlands, and Pakistan were the top recipient countries. Moringa is also distributed in seed kits for home garden projects in Asia and Africa....
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....
