“…Aeroponics is able to produce large numbers of minitubers in one generation that can be harvested sequentially, eliminating the need for field production, thereby reducing costs and saving time [7]. This technique was applied to effectively produce minitubers of yam (Dioscorea rotundata and D. alata) in Nigeria and Ghana [11,12]. Aeroponics could be an alternative production system for other high-value root and rhizome crops, such as great burdock (Arctium lappa) [13], ginger (Zingiber officinale) [14], medicinal crops, such as Urtica dioica and Anemopsis californica [15] and saffron (Crocus sativus) [16].…”

Aeroponics is a relatively new soilless culture technology which may produce food in space-limited cities or on non-arable land with high water-use efficiency. The shoot and root growth, root characteristics, and mineral content of two lettuce cultivars were measured in aeroponics, and compared with hydroponics and substrate culture. The results showed that aeroponics remarkably improved root growth with a significantly greater root biomass, root/shoot ratio, and greater total root length, root area, and root volume. However, the greater root growth did not lead to greater shoot growth compared with hydroponics, due to the limited availability of nutrients and water. It was concluded that aeroponics systems may be better for high value true root crop production. Further research is necessary to determine the suitable pressure, droplet size, and misting interval in order to improve the continuous availability of nutrients and water in aeroponics, if it is to be used to grow crops such as lettuce for harvesting above-ground parts.

“…The improved agronomic practice fields had significantly (P<0.01) higher total tuber yields compared to the farmers’ practice fields across the locations despite the season (Figs 2–4). Availability of moisture is critical for yam to sprout and establish during early growth stages and vital to bulk bigger tubers(11,17–20). Higher rainfall during 2015 cropping season (Fig 1) might have ensured yam establishment and increased overall yields compared to 2016.…”

1516 With about 70% of yam tuber been water, yield is critically affected during bulking as a result 17 of onset of temporal drought. As a consequence of climate change, farmers who are into 18 Dioscorea rotundata (white yam) production for local and international market lose their 19 investments mainly due to erratic precipitation, drought spells culminating into low yields of 20 just 12t/ha compared to the potential of about 22-49t/ha depending on the variety. Innovative 21 land uses technologies with higher and sustained productivity for yam production are 22 imperative. This study verifies improved agronomic package for sustainable yam production 23 in yam growing areas in the forest -savannah transition zone of Ghana during the 2015 and 24 2016 cropping seasons. The improved agronomic package included use of ridging as seedbed, 25 seed treatment before planting, fertilizer application at a rate of 30:30:36 N:P 2 0 5 :K 2 0 kg/ha 26 plus 15 kg/ha Mg and 20 kg/ha S as MgSO 4 and the use of minimum stakes (trellis; 30-50% 27 less number of stakes used by farmers staking). This was compared with farmers' practice 28 which consisted of mounding, no fertilizer application and no seed treatment. The results 29 revealed significant (P ≤ 0.01) yam yields of more than 60% difference between the improved 30 agronomic practice and farmers' practice from Ejura, Atebubu and Kintampo yam growing 31 communities. Adoption of improved agronomic practices does not only sustain yam 32 production and address deforestation but also provide higher returns on investments 33 promoting climate resilience by small holders.

Thus, a potential catastrophe for smallholder farmers and the millions of people who 43 regularly grow rain-fed full season crops such as yam, cocoyam, rice etc.(2-5). Choices about 44 what to grow are often dictated by the ability of the rainfall regime to support moisture for 45 plant growth (6). One way around this would be to breed for varieties with shorter crop 46 maturity durations or management interventions that build on the resilience of cropping 47 production systems to reduce shocks if the shocks from the climate change cannot be done 48 away with. Evidence suggests that climate smart agriculture can make a contribution to 49 mitigation by supporting more efficient use of fertilizers, weed management and reduced 50 staking options in yam production (1,7,8). 51 Yam, an important staple food crop across West Africa is a major non-traditional export 52 crop in Ghana contributing to about 16% of the National Agricultural Gross Domestic Product 53 (9,10). However, there are a number of challenges that hamper the production and 54 productivity of yam. Predominantly amongst them are; inade...

“…Another important aspect is related to the use of canes for vine propagation by classical techniques (by cuttings), by hydroponic or aeroponic techniques systems (Maroya et al, 2014) and by grafting. Basal internodes and buds have a higher vigor, followed by ones with middle placement on the canes length, the terminal buds having a weaker vigor.…”

“…Samples were taken from the vine experimental plots of BUSAMV Timisoara. The canes were analyzed over the entire length (19 internodes; IN [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] ), from each internode being extracted samples, which have been subjected to drying under controlled conditions.

The purpose of study was to assess the rate of water loss from the canes of the grapevine of vines in relation to internodes position on vine chords and degree of wood maturity. The biological material was represented by grape cultivar Burgund mare, to which were analyzed individually all internodes distributed on the chord length (internodes number IN [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] ). The rate of water loss and associated parameters (maximum rate of water loss -RWL Max , total drying time -T, time to achieve RWL Max -t RWLMax ) were determined from the Burgund mare vine cultivar, in controlled condition. Parameters studied were associated with dry matter content (refractometric method), degree of maturity of the wood, and internodes positions on chord. RWL Max had higher values in the basal internodes (IN 2 ; RWL Max = 0.252±0.005 g/min) and lower in the apical internodes (17)(18)(19) ; RWL Max = 0.202±0.011 g/min). RWL Max distributions values, according to the position of internodes on cane was described by a third degree polynomial function, statistical safety (R 2 = 0.949, p<0.01). Dry substance content in internodes (sugar) was correlated with the total time of water loss (T; R 2 = 0.945), the time to reach the maximum rate of water loss (t RWLMax ; R 2 = 0.855), and maximum rate of water loss (RWL Max ; R 2 = 0.984).
