Session 3.4 promotion of teak under an agroforestry system

  2. 2. WCA 2014 2 TEAK: A VALUABLE AND PREFERRED SPECIES FOR PLANTING • One of the most valuable and highly sought after timber for its durability, decorative grains, lightness with strength, seasoning capacity without materially altering its shape, easy workability. • Easy to raise –Profuse seeding –Proven nursery and planting techniques • Hardy species –Can withstand biotic pressures –Can survive under even rain fed conditions and poor soils, however then, its growth will be slower. • Comparatively low planting & maintenance costs. • Fairly fast growing under favorable conditions • Timber prices constantly rising. • Easy marketability.
  3. 3. WCA 2014 3 TEAK: AN ELITE TREE • Teak had been treated as royal tree. • Nationalized timber: Monopoly of state govts. over its trade. • Most of the plantations raised by state forest departments and its agencies. • In private sector also, teak plantations raised by corporate bodies and large land holders only as long term investment. • Small farmers had perceived fear of reduction in crop yield due to shade effect of trees -Contd.
  4. 4. WCA 2014 4 TEAK: NOW, DARLING OF RURAL POOR TOO • Small land holders also are now planting teak as an investment to meet unanticipated emergency expenditures and treating it as an insurance crop. • Although, it depends on their socio-economic conditions and various land use opportunities available to them. • Teak is also a major component of agroforestry systems.
  5. 5. WCA 2014 5 PREVAILING AGROFORESTRY SYSTEMS IN MADHYA PRADESH • PARK LANDS – Presence of trees (naturally occurring or planted) widely scattered over large agricultural plots. – Trees provide shade and also act as roost for insect and rodent eating birds. – Prunings provide firewood. – Common tree species are teak, Babul (Acacia nilotica), Mahua (Madhuca latifolia) • SHADE SYSTEMS – Crops raised under tree canopies – Trees having fairly open canopies. Examples - Teak, Aonla (Emblica officinalis), Eycalyptus sp. – Understorey crops shade tolerant. Ex:- Turmeric, ginger, medicinal plants. -Contd.
  6. 6. WCA 2014 6 PREVAILING AGROFORESTRY SYSTEMS IN MADHYA PRADESH • STRIP ALLEY CROPPING – Crop strips alternate with single or multiple widely spaced rows of closely spaced tree species. – Alley width varies from 3 M to 10 M. – Most common tree species are teak and Khamer (Gmelina arborea) • BOUNDARY SYSTEMS/PERIPHERAL PLANTING – Field bund planting – Boundary planting/Live fence – Can easily accommodate more than 200 plants/ha – Popular among small farmers – Preferred woody prennials are: Teak, Bamboo, Khamer, Babool, Safed Siris (Albizia procera), Ratanjot (Jatropha curcas), Arjun (Terminalia arjuna) -Contd.

  8. 8. WCA 2014 8 • CONTOUR PLANTING ON SLOPING TERRAIN – Lands cultivated by small/marginal farmers (especially tribals) in several districts are situated on sloping terrain. – These lands are not much productive for raising of sole agricultural crops. – Cultivation practices are leading to soil erosion and nutrient loss. – Contour planting of tree species which require good drainage, such as Teak, is an ideal solution. – Most effective on lands with moderate slope of 2-7 % – Contour furrows form multitude of mini barriers across the flow path of run off. -Contd. PREVAILING AGROFORESTRY SYSTEMS IN MADHYA PRADESH
  9. 9. WCA 2014 9 PREVAILING AGROFORESTRY SYSTEMS IN MADHYA PRADESH • Stream and river bank planting – State has large areas situated on the lands of perennial rivers and seasonal streams. – Good plantations of Teak, Khamer, Bamboo etc have been raised on the banks of rivers & streams. • Block Planting – Apportioning a certain part of the land for growing trees in blocks – Spacing varies from species to species and also depends on the object of management. – Preferred by large land holders and absentee landlords. – Preferred species are Teak, clonal Eucalyptus, Khamer, grafted Amla, etc. • Homestead Plantations – Preferred species are Bamboo and edible fruit bearing trees

  13. 13. WCA 2014 13 CHOICE OF MODELS AND SPECIES UNDER AGRO FORESTRY • Choice of species and models location specific dependant on prevailing socio-economic, anthropogenic and environmental factors. • Ecological sustainability and fulfillment of diverse needs of food, fuel, fodder, medicinal herbs, NTFPs etc have traditionally been the main criteria. • But, of late, profitability is the over-riding consideration and therefore, teak is now one of the most popular tree species in all types of agroforestry systems.
  14. 14. WCA 2014 14 FACTORS MAKING TEAK A POPULAR CHOICE • Deciduous species remaining leafless for a considerable period during a year. • Can be raised with most of the arable crops-wheat, paddy, sugar-cane, soybean, mustard, groundnut, vegetables, medicinal plants, etc. • Kharif (rainy season) crops in rain fed areas and Rabi (winter) crops in irrigated areas can be easily raised with teak during initial 3-4 years without any drastic reduction in crop yields.
  15. 15. WCA 2014 15 GROWTH AND YIELD • Fairly fast growing under favorable conditions- well-drained fertile soils, irrigation, fertilizer application, etc. • Growth dependent on number of factors – Soil type – Irrigated / rain fed – Spacing – Tree/Crop combination – Type of planting (Block/row/boundary, etc.) – Inputs (Fertilizers, growth hormones, etc.) – Quality of planting material. – Height of 5-8 m and Girth 12-21 cm recorded for 3 year old plantation under fertigation whereas these figures were 2-3 m and 4-9 cm respectively under rain fed condition.

  25. 25. WCA 2014 25 LOK VANIKI SCHEME • Large number of patches of tree-clad lands/forests/wastelands available under private/community ownership or admin. control of Revenue Department. • Lying unmanaged yielding little or no economic returns. • Owners facing problems in getting permission for felling/transport/sale. • Tempted to somehow get rid of trees standing on these lands • Govt. of M.P. launched a novel voluntary scheme 'Lok Vaniki' to bring such lands under the fold of scientific management. Contd.
  26. 26. WCA 2014 26 LOK VANIKI SCHEME • Enactment of Lok Vaniki Act 2001 and framing of rules in 2002. • Private Forests and Community/Revenue Forests • Management by Private owner/Gram Sabha/ Village panchayat. • Preparation of micro plans for sustainable scientific management. • Detailed prescriptions about regeneration (including planting, protection, tree felling, harvesting, etc.) • Approval of micro plans of area up to 10 ha by D.F.O. and forwarding to MoEF.
