Farmers’ experiences with low-pressure drip irrigation for vegetable production in Southeast Asia and the Pacific
(International Society for Horticultural Science, 2011-12-31)
Low-pressure drip irrigation has been introduced to small-scale vegetable farmers in several countries in Asia and Africa for almost two decades, but adoption and impact of the technology have been limited due to several ...
On-farm evaluation of pepper grafting technology for managing soil-borne diseases of sweet peppers during hot-wet season in highland tropics
(International Society for Horticultural Science, 2012-08-31)
A major constraint limiting yield and production of sweet pepper (Capsicum annuum) during the hot-wet season in the highland tropics is the high incidence of soil-borne diseases including bacterial wilt-BW (Ralstonia solanacearum) and Phytophthora blight-PB (Phytophthora capsici). High temperature and humidity during the wet season favor development of these soil pathogens. A technology on grafting sweet pepper scion onto chili pepper rootstock with resistance to both diseases and flooding was developed at AVRDC – The World Vegetable Center since 2002. Several chili pepper lines were identified with high resistance to BW and PB. From 2007 to 2008, on-farm trials were conducted in Nantou, Central Taiwan to evaluate disease resistance and subsequent yield of sweet pepper cultivars grafted onto resistant chili pepper rootstocks. In both years, the incidence of PB and BW was significantly (P<0.05) lower in grafted than non-grafted plants. Marketable fruit yields averaged over four sweet pepper cultivars (scions) were significantly (P<0.05) greater in plants grafted onto seven chili rootstock lines compared to non-grafted plants. Outstanding and high yielding sweet pepper cultivars were ‘Andalus’ and ‘Hazera’. Six outstanding chili pepper rootstock lines with low incidence of BW and PB were identified in these trials. This study indicates that grafting technology is effective in reducing soil-borne diseases of sweet pepper which leads to increased yield and production during the hot-wet season in tropical highlands....
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....

Electromagnetic effects on seed germination of moringa cultivars
(International Society for Horticultural Science, 2021-04)
Most recently, electromagnetic application in agriculture has increased since plant features were altered significantly in response to pre-sowing seed treatment. Moringa has an extraordinary range of industrial and medicinal uses. This miracle tree is an extremely precious plant with great nutritive importance. The aim of this study was to determine the effect of pre-sowing magnetic field (MF) treatments on seed germination and seedling growth in Moringa oleifera, M. peregrina and M. oleifera cultivar 'Periyakulam-1' (PKM-1). These laboratory experiments were carried out at the premises of the Sara bint Rached bin Ghonaim Research Chair for Cultivating non-Traditional Medicinal and Aromatic plants (SRC), PSAU, Alkharj (24°15'N, 47°30'E), KSA. Three treatments were established using a 75 mT (millitesla) MF with 30 min exposure duration to the seeds of: MFO (T1): seeds of Moringa oleifera; MFP (T2): seeds of M. peregrina; MFPKM (T3): seeds of PKM 1. The obtained results exhibited significant effects on most of the germination parameters; mean germination time (MGT), seedling vigour index (SVI), energy of germination (EG), and final germination percentage (FGP). M. peregrina exhibited the best attributes for most parameters compared to Moringa oleifera and M. oleifera cultivar 'Periyakulam-1' (PKM-1). These findings indicate the possible use of MF treatments for the seed germination and seedling growth of moringa that should be considered in further research studies....
