The area around the tree should be 1 ½ times the size of the canopy and should be kept clean of weeds for the first 2 years to avoid competition. No fertilizer is required, but well-rotted manure at planting is beneficial. Cover the scion and the rootstock by wrapping them with grafting tape.į. Insert the scion into the rootstock and tie them together.Į. Make a wedge cut of the scion of a similar length of 2.5-3.0 cm and sharpen it.ĭ. Vertically cut down the stock between the two leaves to a depth of 2.5 – 3.0cm.Ĭ. Cut and remove the actively growing part of the rootstock, leaving two functional leaves.ī. Scions for grafting are harvested from select mother plants. Grafting is done 3-4 weeks after transplanting into potting bags. Seedlings are ready for grafting when they attain more than two functional leaves and the cotyledons are still attached to the young stem. This composition can sustain the plant for an average of three months after transplanting the pre-germinated seeds in them. The seedlings are transplanted in potting bags (6" x 9"). The recommended soil media for cashew nut seedlings is in the ratio of 2:1:150 where: 2 is two buckets of soil, 1 is one bucket of well-decomposed farmyard manure, and 150gms of DAP. The pre-germinated seeds are transplanted into potting bags when the radicals (tap root) are 2.5 –3cm after 7-10 days. Seeds that sink are planted in pre-germination beds. The selected seeds are taken through a flotation test in water. The first step is a visual selection of seeds to remove diseased or deformed seeds. Propagation through grafting starts by raising rootstock propagated from local cashew nut varieties. Do not interplant young trees with pasture because of the high competition for water during the dry season. Most annual crops can be used apart from cotton and sweet potatoes, which are host plants for Helopeltis bugs, major pests of cashew. Intercropping can be done before the canopies close.
