HI
Important cashew growing districts in A.P. are Guntur, Krishna. East and West Godavari, Srikakulam, Vishakhapatnam, Nellore and Prakasam.
CLIMATE
It requires a warm humid climate, with a minimum of 600mm rainfall, but well distributed rainfall is more important. Cashew thrives under a wide range of temperatures from 15 to 40 degrees centigrade. Cashew does not grow well in areas subject to frost and cold waves. It is also drought resistant.
SOILS
It has a high degree of adaptability and can be raised on any soil free from rocky strata or hard pan and water stagnation. The best soils for cashew are deep friable, welldrained sandy loam soils. Hilly slopes up to an elevation of 700 m above mean scale level can also be utilized for cashew cultivation.
Propagation
Cashew is commercially propagated by seed only. Vegetative propagation through air layering, side grafting, veneer grafting and epicotyle grafting is also possible. Planting material should be collected only from trees possessing all the desirable higher percentage of bisexual flowers, good fruit set, medium sized nut and high yielding capacity of 15-25 years old. Collected seed should be sun dried for 2 or 3 days for seed purpose.
After soaking the seed nuts for about 48 hours in water into hasten germination, they may be sown either insitu or in alkathene bags (25 x 15 cm) filled with garden soil mixed with stalk end up in tilted position. Generally 2-3 seeds are dibbled at the permanent site in pits (60cm x 60cm x60cm) depending upon the topography and fertility of the soil. Germination is completed within a month. One month after germination a single healthy and vigorous sedings is retained in the pit while the rest are removed . Seedling raised in alakathene bags, may be transplanted when they are about 2 months old, without causing any disturbance to the root system during monsoon rains.
Generally the plants are raised in square system of layout.
After care
For the first two or three years , regular watering is necessary for the better establishment of the young seedlings. The young seedlings are stalked and protected from scorching sun in summer by providing shade with palmyra leaves and from cattle damage by fencing. The allies are ploughed to suppress weed growth. The basin of young plants may be mulched with dry leaves to conserve moisture in summer and also to suppress the weed growth in the basins.
Intercroping
Cashew gardens are inter cropped during the initial years only. In forest plantations legumes like ground nut or horsegram are raised as inter crops. In other gardens, vegetables, tobacco and chillies nurseries are raised. However, legumes as inter crops are more beneficial to cashew.
Harvesting
Seeding cashew trees normally come to bearing in 3-5 years after 7 th year and by 10 th year yields will be stabilized.
Cashew flowers in January-February in A.P. Harvesting commences from April and ends May-June. The nuts take 45-60 days to mature. Generally, the fallen fruits are gathered from below the tree and the nuts are separated from the apple.
The separated nuts are dried for 2-3 days to bring the moisture content down to 10-12 % and stored in tins or gunny bags.
The tree yields in cashew vary very widely. An ideal cashew tree should give an yield of 20 kg raw nuts per tree per year. However, majority of the trees yield 2 to 3 kg per tree in the existing plantations.
Investment depends on what area you cultivate, mechanisation, labourers you use.
