Passion fruit farming is still an unexplored kind of fruit farming in Uganda. Apart from the fact that passion fruits, just like any other fruit, has its good and bad seasons, but when properly looked after, these fruits can enable a farmer generate significant income. However, they cannot just blossom, they must be properly planned for to get the best fruits and results.
Thus, knowledge of the best agronomic practices is vital. Lydia Nantabo, an agronomist, highlights the following that can be applied from preparation of land to harvest, storing and marketing.
Land preparation
The best soil for cultivation of passion fruits is sandy loam soil. But that is not a limitation on where to grow them. Once you have set the land for planting the passion fruits. Do the following:
Properly plough the land to allow easy penetration of water and nutrient before making the planting holes. Make them 60cm by 60cm (2ft wide and 1ft down)
Separate the first 30cm of the soil and mix it with the manure you are going to use for refilling.
Get well-decomposed manure and place it in the hole you are going to plant in, two weeks before planting.
You can drench the soil-manure mix with fungicide to kill any fungi that might be in the manure.
If you are preparing to plant during a dry season, water the holes a day before but if it is during the rainy season, you can go ahead and plant.
The spacing from hole to hole or plant to plant is 3m by 2m or 10ft by 7ft. The size of the holes is determined by the labour for at the pruning stage. If you are doing it on your own, you could make bigger spaces or according to your preference.
If you have no labour, avoid planting them too close to each other as this will be tedious during pruning.
During planning, make sure you remove the polythene bags that wrap the seedlings and dispose them off properly because they prevent water retention in the soil.
You can dip the seedling roots into a root stimulant. This allows proper and easy growth of roots.
Varieties
The major ones are the local purple traditional and the local purple hybrid. However, there are different varieties of passion fruits although, these are identified or classified according to the areas such as Masaka, Mbale and Kasese.
Soil and nutrition
This involves indulging in practices or applying substances that improve the soil’s qualities. This can be in terms of how fast the soil absorps nutrients or the rate at which the weeds will grow during the planting season.
Applying the right soil nutrients can improve its structure and yield better results.
Nantabo recommends using organic manure as this helps to balance up the soil although it is better to take a sample of the farm soil for testing so that you know of any missing nutrients.
Passion fruits grow best with soil nutrients such as nitrogen, phosphorous and potassium. The amounts of these nutrients vary at the various stages of growing.
You can add a soil conditioner such as humate. Application of the conditioner helps in soil enhancement, which allows the soil to quickly absorb of necessary nutrients.
If you used manure while planting, you are advised to add NPK (nitrogen, phosphorus, and potassium) after a month. In the second month, use TSP (Triple Super Phosphate) or SSP (Single Super Phosphate). You can then interchange it with CAN (calcium ammonium nitrate), which helps in the fruit tissue development and strengthening of the cover of the fruit.
Once you give the plant good manure, at planting and after three months, you can start harvesting as early as after six months although poor manure distribution to the seedlings delays harvesting even up to nine months.
It is recommended to use the fertilisers (organic and inorganic) interchangeably.
Marketing
There are different buyers depending on the target market.
These different markets or buyers range from traders, wholesalers, retailers, hotels, restaurants, supermarkets and individual customers. Depending on availability of market that is where the farmer will sell. Prices range from Shs1,500 to Shs10,000 or more depending on the market.
Weeding
During land preparation, the garden must be free of weeds. After planting, introduce grass bands which should be kept short to prevent it from overgrowing. The dry grass can then used to mulch or feed animals.
If you decide to weed, do not leave the ground bare.
You can intercrop the passion fruits with strawberries. They are good cover crops, which help to keep the soil covered.
Storing
The fruits can stay for more than two weeks when stored in a place with room temperatures. It is advisable to apply CAN before harvesting so that the shelf life of the passion fruits is prolonged. However, for many local farmers, what is produced is sold immediately.
Care and management
Pests and diseases in passion fruits are a result of planting infected seedlings or using infected seeds, over cropping or transfer by animals from one place to another.
Here, Lydia Nantabo, an agronomist, notes some of the common pests and diseases that affect the fruit and can result in poor fruit quality and quantity.
Aphids: These are pear-shaped, soft bodied insects, with long legs and antennae and are usually green or yellow. They can appear dark or black with or without wings.
Aphids suck the sap, which causes curling or cupping of infected leaves. These insects spread the virus that is responsible for woodliness. Their excreta coats the leaves and prevents photosynthesis from taking place.
Control can be through use of pesticides such as imidachroprude, Jackpot or Aabamectin. You can grow strong-scented plants such as onions, garlic or parsley at the boundaries of the garden. These attract aphids such that you trap them there and thereafter spray them. Avoid excessive application of nitrogen fertilisers as these attract aphids.
Leaf miners: These are black or yellow small flies of about 2mm long when adult. They lay eggs on the leaves that hatch into larvae, which feeds by mining the lower and upper parts of the leaf making long tunnels as they move.
Natural control can be through placing a yellow basin in the garden filled with water. The adult leaf miners are attracted to bright colour. When they fall in the basin, they can be trapped and killed.
Use chemicals that are systemic in nature. These are able to pass through the leaf layers into the plant sap. They include abamectin, thiamethoxam, cyromazine. Other pests that affect passion fruits include bugs, root nematodes, snakes and termites to mention but a few.
The common diseases include the following:
Fusarium wilt (Fusarium oxysporum fsp): This disease is also referred to as colar rot. This is because it affects the stem (colar) much more than any other part of the plant.
This disease may be spread through infected planting materials such as seedlings and seed. Farm tools and animals from infected sites can also carry the disease.
It deforms the xylem vessels that are responsible for the movement of water and nutrients in the plant system. This leads to the yellowing of leaves.
If the colar (stem) is attacked, it becomes brown, peels off and cracks vertically. This makes the vine wilt.
For a control measure, graft weak passion fruit varieties on to yellow root stock. This is because yellow root stock is resistant to the disease. Fields that are already affected with fusarium wilt should be left to rest from passion fruit for about six planting seasons.
During this period; other crops can be planted to break the cycle. Keep the orchard clean and free from plants that are affected. In case, there are affected plants, pruning should be done, the plants removed and disposed of. Avoid excessive use of fertilisers.
For chemical control, paint the colar with macozeb mixed with metalyxl to prevent further development of the fungus. Copper-based fungicides are also very effective.
Passion fruit blight (phytothora nicotiamea var parastica): This usually affects the leaves, which become thin, water-soaked, light brown in colour and eventually fall off. The stem turns brown, weak, wilt and later collapse and die out.
Good field practices can help reduce the disease drastically. All weeds should be kept low by slashing, plants should be pruned regularly and the pruned materials should be disposed of properly. Fruits that fall on to the ground should be picked and disposed of. Avoid vines touching the ground.
Chemical control includes use of macozeb, macozeb + metalyxl to spray on the crop. Farmers should spray at least once a week in case the prevalence of the disease is high, and once after every two weeks in case the disease incident is low.

Passion fruit is a perennial vigorous vine, which grows to give oval or round shaped fruit.

This vine is native to tropical regions of southern Brazil; this succulent fruit is also grown in Uganda and mainly in Masaka and Kasese districts’.

The fruit is easy to grow as it gives back to the farmer in only 8-12 months.

Where to Find Market for your Passion Fruits


In addition to the local Ugandan markets, the European and the growing supermarkets in Burundi, Dr.Congo, Rwanda and South Sudan present new market opportunities for passion fruits grown in Uganda. 

Common Passion Fruit varieties in Uganda



The purple Grandilla-Is popular for its scent and is locally known as Kasese, Masaka and Kenyan passion fruit variety. 

Highly resistant Kawanda hybrid- this is a cross between the local purple and the yellow passion fruits.

Yellow passion -This passion fruit is grown for its aromatic but rather acidic pulp.

Soil requirements for Passion Fruits



Passion fruit plants require fertile soils with plenty of mineral supply in order to achieve optimum growth and yields. 

A soil pH range of 6.0 to 6.5 is the best.

How to propagate Passion fruits in Uganda 

Propagate your passion fruits using either seeds, stem cuttings, or even grafted prop gules.

How to plant Passion Fruits in Africa



Plant passion fruit in at least (2x20) ft width and 3ft depth. 

The holes must be well fertilized. 

Open up the planting holes at least 2-3 months earlier. This gives room to kill the soil pests and it borne diseases. 

After mix the top soil with compost and then put it back, as this is very important at the initial stages. 

To further boost the plant growth, add NPK and CAN fertilizer at the climbing stage and when the branches start to develop.

Harvest your passion fruits 4-6 weeks after transfer to the main field. 

Trellis the fruit plant with 270 cm long and 15 cm in diameter posts. Place these posts in 60 cm deep holes spaced at 6 m apart in rows midway between the plants.

Opt for companion planting as you inter-crop passion fruits with green paper, onion, carrots and other short term veggies. However avoid crops like maizebananas; sugar canes as these are heavy feeders.

How to Harvest Passion fruits in Uganda


Harvesting of passion fruit stars from 8-12 months especially for the purple ones. 

Pick fruit when they turn from green to purple, and when the calyx has dried up leaving a small stalk attached. 

For processing, fruits should preferably be left to drop on to clean mulch. They should not be plucked from their stems. 

Usually fruits which have dropped can be collected once or twice a week. During the rainy season they should be picked up every other day and kept in a cool place.

Quick Tips for growing passions in Uganda



  • Deep plough the proposed site to open up soil for proper aeration and water filtration.

  • Open up planting holes of (45x45x45) cm in advance.

  • Mix the top soil with compost and then put it back to the hole.

  • Transplant the germinated seedlings at the onset of the rainy season.

  • Transplanting should be in the morning or late evening to reduce chances of their failure due to heat stress.

  • Alternatively you could start with seeds.

  • Soak the seeds in warm water to facilitate germination.

  • Leave the seeds to air dry before main planting is done.

  • Place the seeds in a 1 cm deep in polythene pots.

  • Thinly cover with soil and then water to facilitate germination.

  • When seedlings grow to a height of (20 to 25) cm, transplant them to their main location.

  • Harvest passions when the green cover of the fruit turns purple.

  • Invest in security by at your passion fruit garden by posting a full time Security guard and erecting a secure fence. This is especially useful during the harvest season.
