Pepino

Resource by Plusfarm

The Pepino melon is an herbaceous Andean fruit grown mainly for its juicy and aromatic fruits. It has leaves resembling those plants and if left un-pruned grows into a low dense bush and has more a scrambling nature like a determinate tomato. It thrives well in tropical climate of Kenya and its soils. The fruit is typically a bright green or yellow green and often has some red or purple striations. The flesh is golden yellow when ripe with a narrow seed cavity. The melon is entirely edible; skin, flesh and seeds. The fruit is very sweet and juicy.

Cultivation

Ecological requirements

cool season crop tolerant to conditions areas with an altitude range of 1500-3000 M ASL.for optimal performance, a temperature range of 12°C-24°C is suitable. Production is affected by relatively high temperatures. Rainfall requirement annually is between 800-1200mm.

The plant should be planted at a spacing of 2-3 feet.

Soil requirements

The plant requires well-drained loam soils with a pH of 6.5-7.5. The plants should also be well watered and weeded. The soil depth requirement is 30 cm. Pepino plants may be grown in sandy, loamy, or even heavy clay soils, although they prefer alkaline, with an acid. Pepinos should be planted in sun exposure and in moist soil.

Crop Management

The crop also adapts well to greenhouse cultivation, training the plants up to 2 m tall, and obtaining yields that are 2-3 times larger than those obtained outdoors. They are propagated by cuttings since they are established easily without rooting hormones. It is grown in a manner similar to its relatives such as the tomato, though it grows naturally upright by habit and can thus be cultivated as a free-standing bush, though it is sometimes pruned.

Additionally, supports are sometimes used to keep the weight of the fruit from pulling the plant down. It has a fast growth rate and bears fruit within 4 to 6 months after planting. It is a perennial but is usually cultivated as an annual. Established bushes show some tolerance to drought stress, but this typically affects yield. The plants are parthenocarpic, meaning it needs no pollination to set fruit, though pollination will encourage fruiting.

Post Harvest

Fruits mature within 30-80 days after pollination. However, the fruits do not mature at the same time. Fruits should be picked only when completely mature in order to assure the highest flavour and sugar content.

Ripe flesh of the fruit is pale yellow-orange in colour. Fruits are harvested once they have fully ripened and can be stored for several days.

They can be eaten wholly and are also useful in making desserts and as addition to fruit salads. Don’t be tempted to harvest fruit before they are really yellow since they won’t have acquired full sweetness. Ripe flesh is a very pale yellow-orange in colour. Pick the ripest fruit in the cluster, and the others will continue to mature. Handle carefully since they bruise easily. They can be stored on the kitchen bench for several days, or in the refrigerator for several weeks provided the temperature is not below 5° C.
