Afforestation
Neem has been employed on dry sites in various localities for reforestation and Afforestation and as
a popular shade and avenue tree. It is very thrifty species and has been found to survive under very
exacting conditions. It is extensively used in rab regeneration of the fuel coupes in Tamil Nadu and
Andhra Pradesh and has given consistently good results. Telenkheri hill near Nagpur has been
afforested by planting nursery seedlings. In the Yamuna ravines, where intercalated pans of
calcareous nodules (kankar) frustrated attempts to raise babul plantations, basket plants of neem
put out at the break of rains inside thorny bushes in pits of 46cm x 46cm have given excellent results.
Neem has also proved successful in recent Afforestation works in the arid and semi-arid regions of
Andhra Pradesh, Maharashtra and Rajasthan. It is one of the species prescribed for growing within
railway station yards and along the strips flaking the railway track in the northern zone.
Neem can also be used for the Afforestation of ‘usar’ soil by good ‘non-usar’ soil. A pit 0.6m wide and
1.2m deep is quite adequate for this purpose, as it helps to break the kankar pan, if any, and provides
enough volume of normal soil for sustaining a moderate size tree. Depending on the nature of the
soil, adequate quantities of farmyard organic fertilizer and gypsum may also be applied in the pits
with advantage. In the case of salt-affected soils, watering during periods of drought and during the
following summer may become necessary. The rate of growth is slow and height of 6-12 m may be
expected in 20 years, with a diameter of 20-26 cm. Under these conditions, neem is likely to be short-
lived with an expected average life of 20-25 years. Such plantation of the site, making it fit for
moderate quality pasturage and poor wood production. Neem has been introduced into North, West
and East Africa where it is growing and reproducing well in the drier parts. In Sudan, it is used for
windbreaks around plantations.
