“…This is confirmed by Ayankanmi et al [32] showed that treatment with 2% urea increased the number of roots per cut (38.16%) on the 20th day after transplanting. The results obtained in our study corroborate those of Igwilo (2003) [35]. According to these authors, the use of a hormonal solution composed by 50 ppm AIA 3 , 5 ppm GA 3 and 10 ppm Benzyladenin increases the number of roots per vine cuttings of D. rotundata.…”

“…2010)[38] who found the formation of roots of vine cuttings from two clones of D. rotundata three weeks after transplanting onto a medium containing sand. In addition,Igwilo (2003) [35] reported that after 14 days, cuttings of the Obiaoturugo variety (D. rotundata) showed a high rooting rate. In our study, the highest mean root number was recorded with growing media containing 0.25% NPK8-8-8 (20.3), 25 ppm AIA 3 (17.7) and mixed media 25 ppm AIA 3 + 5 ppm GA 3 + 0.5% NPK (16.5).…”

Vine cutting is an effective solution to solve the problem of seed availability in yam cultivation. This study was conducted to improve the recovery and rooting rate of vine cuttings of Dioscorea rotundata. Two-node cuttings from five (5)-month-old hybrid plants were grown in liquid media consisting of phytohormones (AIA 3 and GA 3) and liquid fertilizer (NPK 8-8-8) at different concentrations. Observations were made weekly from the 21st day after transplanting and focused on the survival rate of the cuttings, the number of roots emitted and the number of minitubers initiated. The results obtained showed a significant effect of the different growing media on the survival rate, rooting and production of minitubers. The best survival rates were obtained for cuttings grown in NPK (8-8-8) at 0.25% (100%) and AIA 3 at 25 ppm (93.3%). The highest averages root number was recorded with growing media containing 0.25% NPK 8-8-8 (20.3) and 25 ppm AIA 3 (17.7). Growing media with 0.25% NPK (8-8-8) and 25 ppm AIA 3 provided the highest average numbers of minitubers initiated, respectively 5 and 4.6. Growing medium containing 0.25% NPK 8-8-8 has been identified as the one that allows better roots emission and minitubers production by yam vines cuttings.

“…Moreover, in contrast with the results observed by Anand et al [21]) and Ford et al [20] who obtained an improvement of rooting either with Ipomoea and Prunus cuttings, development of salicornias roots was severely inhibited when treated with GA3+CNH (Table 4). All the plants previously treated with GA3 showed a root growth depression, as observed by other authors on different kinds of plant cuttings [19,[22][23][24]. One of the explanations for rooting inhibition could be that explants were exposed to light as it happened with Carvalho et al [22] and Carvalho [25].…”

Details of investigation to evaluate the effects of the number of nodes (one, two or three) of Sarcocornia fruticosa explants on growth and multiplication rate of plantlets are presented in this paper. The responses of the 3-node explants to some supplementary sources of different aminoacids and growth regulators indol-3-acetic acid, 6benzylaminopurine and gibberellins A3 were also analysed. Plantlets from 3-node explants showed a marked increase in growth and number of lateral shoots, indicating that Sarcocornia does not respond well when explants are very small. The addition of 100 mg l -1 casein hydrolysate plus 150 mg l -1 glutamine, and 100 mg l -1 casein hydrolysate plus vitamins showed to be good growth promoters in micropropagating Sarcocornia, giving longer plantlets and higher multiplication rates.

“…According to Igwilo (2003), yam setts can be multiplied into millions through yam propagator organs which substantially increase the volume of planting materials thus increasing the quantity of the crops harvested. It is possible to cut yam tubers into smaller fragments, or minisetts and thereby increase the coefficient of multiplication.…”

The study investigated farmers’ adoption of yam minisett technology in Agricultural Zone 3, Rivers State, Nigeria. The objectives of the study were to examine farmers’ level of awareness of yam minisett technology in the study area, to access the extent of adoption of yam minisett production technique in the study area, examine the constraints to adoption of yam minisett technology in the study area and to determine the influence of yam minisett utilization on the yield of yam in the study area. The study adopted a survey research design. A sample of 360 farmers was selected using random sampling technique. Structured questionnaire was used for data collection. Frequency, percentages, mean and standard deviation were used to analyze and realize the objectives of the study. The findings of the study reveal that farmers in the study area had low awareness level about the yam minisett technology and adoption of the yam minisett technology. Cost of innovations, lack of technical efficiency and low sprouting rate of minisetts, poor extension delivery service and the top-down extension approach which does not take cognizance of farmers-identified production problems, lack of youth participation and involvement in farming (yam production) as a result of search for white-collar jobs, socio-economic characteristics such as educational level or background, and lack of land to commercially produce in quantity, among others are constraints to the adoption of yam minisett technology in the study area. It was recommended that the farmers should be encouraged to engage in training and to seek financial assistance in order to overcome the problem of scarcity and high cost of inputs.
