That passion fruit is among the fruits that have great economic importance in Kenya cannot be gainsaid. The demand for passion in both local and export market is huge. Kenyan farmers have not fully exploited this opportunity due to various challenges that we are trying to address. For the past 6 months we have been on the ground working hand in hand with farmers in Nyahururu, Uasin gishu, kitale, and Migori to develop purple passion fruit orchards that meets the export market threshold. This article will highlight the various processes we applied to ensure effective cultivation, harvesting and marketing of passion fruits.
There are 2 types of commercially grown passion fruit in Kenya; purple passion fruit and the yellow passion fruit. At the moment, we are concentrating more on the purple passion fruit due to its potential for fresh market and juice extraction both in the local and export market. Purple passion is most suited to upper midlands and highlands with an altitude of 1100m-2500m above sea level with temperatures ranging from 18-28 degree Celsius. They can be grown in a wide range of soils provided there is adequate drainage with a soil PH of between 6.0 – 6.5. The cultivation site should be exposed to enough sunlight with an annual rainfall of 900mm – 2000mm per year. Irrigation systems can be designed and developed in areas that don’t experience enough rainfall. A single plant can consume 20 litres of water per week.
organically grown grafted purple passion seedlings
Passion fruit is propagated through seed, grafting and tissue culture. We raise our seedlings organically using beneficial fungi and bacteria that come from the soil to control pest and diseases from the initial stage of propagation. We solarize the soil and use Trichoderma that prevents nematodes and soil diseases and also promotes root growth and yields. Our rootstocks are raised from the bitter yellow passion variety called Zimbabwe and we graft using the purple passion scions. We do assist our clients in setting up a passion fruit seedling nursery once they have grown the plants. This comes in handy when one wants to replace diseased plants or plants that have reduced productivity. The seedlings can also be sold to other farmers offering an alternative source of income. If one is purchasing seedlings elsewhere ensure to get certified planting material from reputable seedling suppliers.
The passion fruit plant should be trained to grow on trellises for optimum growth and yield. The spacing of the poles is directly related to the spacing of the passion fruit plants. The poles are to be placed between 2 or 3 passion fruit plants, spaced 3 metres a part. Intermediary poles can be introduced to prop up the wire in case of heavy fruiting. The distance between rows is usually 3 metres and the rows should be parallel to the direction of the wind. During planting one should dig 2 by 2 feet holes and mix the top soil with organic manure before planting. Minimum investment for one acre passion orchard ranges between Kshs 80,000 to Kshs 100,000.
For optimum production, passion fruit plants need training, pruning, weeding, fertilising and crop protection. Start training the passion fruit vines at an early stage, allow 1-2 vines of each plant to run along the trellis as main vines, this allows laterals from the main vines to grow downwards bearing fruit. Prune to eliminate unwanted shoots and vines to permit systematic growth. The nutrient status of the soil will determine which fertilizer program to be embraced, for this reason a soil analysis and test is of great importance. Weed frequently to reduce competition for nutrients and unwanted pests and diseases. Ensure phytosanitary standards are highly observed, this will help reduce cases of diseases and pests that include fusarium wilt, woodiness virus complex, brown spot etc. We do have an integrated pest management strategy that we are implementing with the farmers we are working with to ensure that the fruits harvested can be accepted in different markets both locally and internationally.
The initial harvest can be expected from the 7th month. The fruit matures in 2 months after flowering and will naturally fall in the ground when mature. Export market destined should be harvested before they fall off naturally to increase the fruit’s shelf life. A mature vine can produce one main harvest and two smaller harvests annually. With proper planning and timing one can harvest all year round. We do organise capacity building training sessions that imparts practical and functional skills on IPM for passion fruit, proper harvesting, packaging methods and accessing markets both locally and internationally.
