“…These may be more appropriately suited to their villages' specific conditions and more appealing to local demands (Contreras-Díaz et al, 2017). Grafting is the standard practice for the renewal of elder cacao trees whose productivity started decreasing, but properly doing such procedure usually requires direct learning from technical assistants since a graft failure may compromise the tree itself (Sodré & Gomes, 2019). On the other hand, the adoption of irrigation implies that the water requirements are adequately covered and that the crop is highly likely to avoid ponding risks.…”

<p>Multivariate and ordered Probit models were used to study the determinants of the adoption and extent of adoption of agronomic practices among cacao farmers in Nariño, Colombia, with data from 353 farmers in the mountain region. Results suggest that farmers’ adoption decisions are made on a joint basis, further validating the use of a multivariate approach. The presence of illegal crops creates strong disincentives that affect the possibility of more significant technological improvements. Adequate access to agricultural technical assistance strongly increases rates of adoption. Evidence suggests that efforts are necessary to better target resource-poor farmers.</p>

“…PH-16 cacao has a high nutritional demand similar to other hybrids generated from crossing with Trinitarian plants [25]. PH-16 cacao shows a versatile adaptability to different climatic conditions, being found in commercial crops from humid to semi-arid zones [23,26]. This clonal variety displayed good production responses in semi-mechanized systems with chemical weeding control, sprayed pesticides and pruning, as well as the use of windbreaks and drip irrigation [26].…”

This clonal variety displayed good production responses in semi-mechanized systems with chemical weeding control, sprayed pesticides and pruning, as well as the use of windbreaks and drip irrigation [26]. Several attributes of cacao quality were analysed in samples from the PH-16 clone, including the total amount of free amino acids [1].…”

Free amino acids in cacao beans are important precursors to the aroma and flavor of chocolate. In this research, we used inferential and explanatory statistical techniques to verify the effect of different edaphic crop conditions on the free amino acid profile of PH-16 dry cacao beans. The decreasing order of free amino acids in PH-16 dry cacao beans is leucine, phenylalanine, glutamic acid, alanine, asparagine, tyrosine, gamma-aminobutyric acid, valine, isoleucine, glutamine, lysine, aspartic acid, serine, tryptophan, threonine, glycine. With the exception of lysine, no other free amino acid showed a significant difference between means of different edaphic conditions under the ANOVA F-test. The hydrophobic free amino acids provided the largest contribution to the explained variance with 58.01% of the first dimension of the principal component analysis. Glutamic acid stands out in the second dimension with 13.09%. Due to the stability of the biochemical profile of free amino acids in this clonal variety, it is recommended that cacao producers consider the genotype as the primary source of variation in the quality of cacao beans and ultimately the chocolate to be produced.

“…This working very difficult than other methods applied in dicotyledoneae plant. Sodré and Gomes (2019) state that plant buds as main source of mass plant is limiting number, different quality and very susceptible to environment. These technique need more skills and maintenance in field.…”

The one of human effort increasing productivity and high quality of cocoa is rehabilitating plant using plant materials with high production and resistant clones to Cocoa Pod Borer. The common methods using side and budwood grafting technique. The research objectives is to compare two grafting technology for old cocoa plant, community empowerment in developing side grafting of cocoa plants by means improve technical skills and develop of farmers in Mamuju Regency. The research was conducted for two years (2017 and 2018) used locations of farmers cocoa plantation in Papalang District, Mamuju Regency, West Sulawesi, Indonesia. The research was held in the two stages: (1) Consultation and coordination with relevant agencies such as: Plantation Service, Trade Service, Meteorological Agency at Provincial and District levels used interview techniques and secondary data collection (area size, number of cocoa farmers, production and productivity, sale and selling price, climatic and soil condition). This activity gaining support from the local government and other stakeholders related to cocoa development; (2) testing the cocoa vegetative propagation technique by side and budwood grafting at the farmer and seed breeder level. Observations were made on the percentage of successful plant connections, plant growth, number of seeds produced per unit time and business feasibility analysis used the B/C ratio. The results were showed that the success rate of the connection achieved was actually higher for side grafting than budwood grafting. The success rates of cocoa clones budwood grafting and side grafting at first month were 83.3 and 90.3%, respectively. Until the fourth month after grafting, the percentage of superior cocoa clones can planted in the plantation still more than 80%. The success rate of cocoa growing in second year (2018) at Papalang District after applied by two technical grafting. There are budwood grafting result only around 88.5%. The side grafting was showed the higher success rate about 94.5%. Finding of research at Mamuju, the attack of Cocoa Pod Borer (CPB) Conopomorpha cramerella Snellen, as the main pest insect of cocoa has potential decreasing plant productivity. As the conclusion of the research: (1) the success rates of superior cocoa clones budwood and side grafting at first month were 83.3 and 90.3%, respectively; (2) in the observation of second year (2018), there are budwood grafting result only around 88.5%. The side grafting was showed the higher success rate about 94.5%; (3) need more effort farmer control CPB and avoid insect population outbreak very fast in the plantation. This situation will change by transfer of new technology and more support from the Government for increasing cocoa productivity.
