Bark: Neem bark contains tannins which are used in tanning, dyeing, etc. Compounds extracted from neem bark are used in production of some dental – care products. Neem bark is also tapped for gum.

Seed: Neem seed pulp is useful for methane gas production. It is also useful as carbohydrate – rich base for other industrial fermentations.

Neem tree has great potential to help small and marginal farmers in rural India, Africa and Latin America. Farmers, who have limited resources, can benefit in many ways from neem. There are easily exploitable, employment and income generation opportunities in the cultivation of neem and processing of neem products, some of which are possible in a decentralized manner on the basis of small investments.

According to some estimates, there are about 20 million neem trees in India. This inter-state estimate is slightly less than current estimate of 20 million. A neem tree normally starts fruiting after 3-5 years. In about 10 years it becomes fully productive. Under favourable conditions fresh fruit yield per fully grown tree is about 50 kg per year. If 50% are accessible and tapped, the total neem seed production may well reach the level of 5 million quintals. Present level of collection is far below 50% which shows the potential for additional employment and income generation. If commercial plantation and agro-forestry involving neem in popularized, the potential goes up significantly, with positive and large externalities for pesticides, fertilizers, livestock, dairying and other value-added products.
