NURSERY TECHNOLOGY

NURSERY TECHNOLOGY FOR IMPORTANT TREE SPECIES

Forestry as a sector plays a vital role in the socio-economic and rural development of a country apart from its role in maintaining ecological stability particularly in a developing country like India. Forests are a traditional source of a multitude of products particularly with regard to fuelwood, fodder, small and constructional timber and have sustained large masses of population. The vast potential of forests to generate employment especially in rural areas, thereby contributing to rural incomes and poverty alleviation has remained unutilized.

The country's forests are under tremendous pressure due to the indiscriminate removal of timber, fuelwood, fodder and other forest produce.

Though there are various afforestation and plantation programmes being implemented by the State Forest Departments, Forest based industries, NGOs, etc., availability of quality planting material well in time and in close proximity to areas where afforestation is to be taken up remains a major constraint in taking up large scale afforestation of wastelands, private lands, etc.

The National Forest Policy stipulates that one third geographic area of the country should be brought under forest/tree cover. Keeping the same in focus, the Approach Paper to the X Five Year Plan has targeted to bring 25 percent area under forest/tree cover by the end of the Tenth Plan period and 33 percent by the end of the Eleventh Plan period. It also emphasises on establishment of modern nurseries on a catchment area basis to provide quality planting material. The steady depletion of forest resources and increasing deforestation has brought into focus the realisation that the active participation of the communities is necessary for the success of any forest regeneration programme. It is also well known that village communities would have little incentive to participate unless they benefit directly.
Promotion of decentralised nurseries through credit in the rural areas will lead to easy and timely availability of planting material and in the process lead to creation of employment opportunities and income generation in the rural areas. Forest nurseries will be one of the means for active participation of the communities in future forest regeneration programmes. The proposed large scale afforestation will require establishment of decentralised nurseries through credit support.

The decentralised nurseries can be established by farmers, SHGs, State Forest Development Corporations, forest based industries, NGOs, etc.

The nurseries should plan to produce healthy plants covering timber, fuel, fodder, fruits, non-wood forest produce and even ornamental species having good demand in the locality. Besides this the prevailing agro-climatic conditions in the area should also be taken into consideration while selecting the species.

An area of 0.25 ha. has been considered for a viable nursery wherein 1.25 lakh seedlings can be raised. The size of the nursery may be increased according to the borrowers category, capacity and demand for planting material. The nursery should be on a gently sloping land to ensure proper drainage. Site preparation will be done by ploughing and hoeing the land. Initially the nursery will be raised in mother beds and will be pricked out in polypots. It should have water as a perennial source to ensure adequate supply in hot weather and to reduce costs. The shape will be rectangular and would measure 100m x 25 m.

Ten seed polybeds would be raised of 10m x 1m i.e. 10 sq m. The number of polybeds required at this stage is at 1:12 ratio i.e. 12 polybeds for each of the primary/seed polybeds. The 1.25 lakh seedlings will be raised in a total of 120 polybeds (1000 seedlings per polybed) of which 1.20 lakh seedlings would be raised in polybags and remaining 5000 will be naked rooted seedlings.

The seedlings will be hardened in the nursery by reducing the water supply over a period of time and exposing them to sunlight over different durations. This would make them capable of facing adverse weather conditions once they are transplanted onto the field. The nurseries are temporary in nature and are of five year duration. During the summer months, shading may be provided by using polythene sheets or shading nets. Bamboo mats can also be used for providing shade. Protection measures may be taken like fencing the area with barbed wire.

The total cost of raising a nursery with 1.25 lakh seedlings has been estimated at Rs.2.172 lakh for the first year. The capital cost works out to Rs.0.802 lakh to be incurred in the first year. The recurring cost works out to Rs.1.37 lakh. The detailed item wise and year wise unit cost is furnished below assuming a wage rate of Rs.50/- per manday.

Since the saplings would be ready for plantation anywhere from the 6th month to 12th month depending on the species, returns will be generated from the first year onwards. The returns have been calculated by taking 10% mortality and 90% of actual sale of the surviving saplings. The cost has been considered at Rs.2.50/- per sapling.

The beneficiaries may contribute towards down payment ranging from 5 to 25% depending upon their category, i.e., small and other farmers in accordance with NABARD's norms. Beneficiaries own labour can also be taken as his contribution towards the margin money requirement.

The loans extended by the banks to individual farmers and / or groups of individuals such as co-operatives under Wasteland development projects are eligible for refinance from NABARD to the extent of 100% of Bank loan.

The rate of interest on refinance from NABARD will be as per the circulars issued by NABARD from time to time. The rate of interest to be charged to the ultimate borrowers would be decided by the financing banks. However for working out the financial viability and bankability of the model project we have assumed the rate of interest as 12%.
