“…In situations in which pollination rates are of concern and when labor costs allow, artificial pollination management strategies have been implemented for cacao (Francis K. Padi, C.R.I.G., 2018, personal communication) as well as other perennial crops (Pinillos and Cuevas, 2008). A hand-pollination program launched in 2017 by the Cocoa Health and Extension Division of the Ghana Cocoa Board observed greater yields than the previous year (Francis K. Padi, C.R.I.G., 2018, personal communication).…”

Artificial pollination management strategies are a potential solution to improving the livelihoods of smallholder cacao farmers by increasing crop productivity in situations when pollination services are limiting. However, field-based research trials evaluating the yield benefits of artificial pollination management strategies within intensified cacao systems are lacking. Thus, in an intensively managed cacao system, we evaluated the effects of artificial pollination condition (i.e., pollen genotype, pollination intensity, and pollination synchrony) on fruit development and yield in three high-yielding cacao clones. Artificial pollination, regardless of intensity, significantly increased fruit set and yield. Pollination synchrony had a significant effect on cherelle survivorship; older cherelles had greater survival rates across all developmental stages than younger cherelles. Yield differed between genotype crosses and varied according to the pollen donor used, highlighting the importance of understanding self- and cross-compatibility when selecting clones for cultivation. Pollination intensity had no significant effect on harvested yield, indicating that more rigorous research is needed to identify the pollination intensity required for optimized yield under artificial pollination conditions. We conclude that strategies to enhance flowering, pollination rates, and pollination synchrony while ensuring adequate tree nutrition may increase productivity in cacao. Future research evaluating numerous cacao clones across multiple years and locations may help us to understand the region-specific effects of intensive management strategies on the long-term sustainability of enhancing cacao tree productivity.

“…In some rare circumstances where high value crops are grown beyond their native range, such as cherimoya (Annona squamosa) grown in Spain, there are no suitable insect pollinators available, necessitating that producers employ labor-intensive artificial pollination methods (Gonzalez et al, 2006). Artificial pollination is usually accomplished by directly applying pollen to floral stigmas by hand using brushes (Pinillos and Cuevas, 2008); however, recent engineering advances have resulted in cost-effective pollen sprays for use in small orchards (Sakomoto et al, 2009). …”

“…Ease in doing controlled and efficient pollination due to complete outcrossing Dichogamy encourages outcrossing through temporary separation of male and female parts hence with the technique of controlled pollination it is easy to repair the crop load (Pinillos and Cuevas, 2008). As with Annona cherimoya, where protogynous dichogamy is demonstrated, hand pollination shows better results in fruit yield and quality (Richardson and Anderson, 1996).…”
