Silviculture and Forest Management

This division was created in August 1992 and has assumed critical importance in the semi-arid tropics where high mean annual temperature and low variable rainfall are serious constraints in crop production. It is engaged in designing agro forestry models for improving land use in various agro-climate regions based on different tree-crop production systems, their spatial geometry, production of goods and services and their ecological impact. The division also carries out regular market survey of  timber and non-timber  forest  products and socio-economic studies. The research priority of the division is to develop site specific  agro forestry systems which  is socio-economically  viable and acceptable by the farmers  residing nearby. So  far various agroforestry systems like Silvi-agri system, silvi-horti-agri system, Silvi-medicinal system, Silvi-pastoral system, agri-lac systems were developed by the division.

This Division is the core division of TFRI, Jabalpur. The mandate of the division is to carryout researches on various aspects of Non-Wood Forest Products viz. conservation, cultivation, sustainable harvesting and value addition of NWFPs including medicinal and aromatic plants, biologically active phyto-chemicals, gums, mucilage, dyes, fibre yielding species, tree borne oilseeds of forest origin and biofuel.

This division was established to pursue applied research on silvicultural and forest management aspects. The activities of this division have been focused mainly on the development of nursery and planting techniques of various species, seed technology, seed ecophysiology, regeneration of forest species, assessment of silvicultural management systems, sustainable harvesting techniques of medicinal plants. 

Ongoing Projects:

(A) In Agfoforestry field

  1. Development of multitier cropping (Silvi-Agri-Spice) system

  2. Development of lac based agroforestry (Silvi-Agri-Lac system)

(B) In NWFP Field

(1)    Evaluation of Schleichera oleosa (Kusum) fruits for their nutritional value and development of value added products for economic development of local people.                                        ID No. 190/TFRI/2012/NWFP-2(34),  Project period:  2012 – 2016

Under this project, Kusum fruits were collected from the forest areas in the month of June & July. The pulp was separated from fruits and evaluated for nutritional value (protein, fat, carbohydrate, fiber, vitamin-C etc.). A protocol for storage of pulp was also developed. Different value added products like Kusum vati, Kusum squiash, Kusum sarbat, Kusum Murabba etc. were prepared.

(2)    Standardization of processing and storage techniques of Malkangni (Celastrus panuculatis), Paheda (Terminalia belerica) & Baividang (Embelica tsjeriam-cottam) fruits/Seeds.  ID No. 206/TFRI/2013/NWFP-1(37), Project period:  2013 to 2016                                             

Under this project, fruits/seeds of selected medicinal plants were collected form Madhya Pradesh & Chhattisgarh state. The fruits/seeds were dried in sun-shade & oven and powder was made.  The powdered materials were evaluated for their active ingredients using HPTLC technique. The sun dried fruits/seeds were found to have more active ingredient. The dried materials were stored in different containers like Jute, polythehe, tin, plastic, steel and these stored materials were evaluated for their active ingrediants at three months intervals to find out the appropriate storage conditions & suitable containers.

(3)    Standardization of non-destructive harvesting practices of Commiphora wightii (Guggal) gum oleogum resin in Madhya Pradesh ID No. 208/TFRI/2014/NWFP-1(NMPB)(38)   Project period: 2014 to 2017

 For standardization of non-dustructive harvesting practices of Commiphora wightii (Guggal) gum oleogum resin, different girth size plants were selected at Bhind, Morena and Gwalior districts and different type of incisions were made for tapping of oleogum resin.

(C) In Silviculture Field

  1. Studies on the effect of different level of seed collection on natural regeneration of Sal (Shorea robusta) in Chhattishgarh. (Externally funded)

  2. Germination ecophysiology of two important tropical forest tree species : Schleichera oleosa and Pterocarpus marsupium.

  3. Standardization of the techniques for germination, collection and maintenance of maximum viability of four important tropical species: Bridelia retusa, Sterculia urens, Boswellia serrata and Saraca indica.

Major Achievements:

A. In agroforestry

B. In NWFP

Standardization of Non-destructive harvesting practices

           

Arjuna: Bark harvesting

1015

Maida: Bark harvesting

 ·         A non-destructive harvesting practice for MFP-Cyperus scariosus R Br. (Nagarmotha) was standardized. For sustainable harvesting of Nagarmotha, on first priority 90% plants and on second priority 80% plants should be harvested uniformly from the whole plot to insure proper regeneration.

Significant achievements:

In Agroforestry

PROJECT  1: Evaluation  of  medicinal plant based agroforestry  system (Silvi-medicinal) under existing teak plantations.  (ICFRE funded project)

Achievements :

  1. Successfully  established and grown medicinal plants (except Gloriosa ) under Silvi-medicinal system at On Station Research (OSR) and On Farm Research(OFR).
  1. Under the Silvi-medicinal system, C. longa performed significantly better followed by C. speciosus  and G.superba in terms of tuberous yield and qualitatively (its active ingredient).
  1. Hence data indicates that Curcuma and Costus can be grown successfully under the 12 year old teak plantations  as these crops are shade loving in nature.

 

         PROJECT 2 : Evaluation of productivity of maize in Dalbergia sissoo (Shisham) and Zea mays (Maize) Agro forestry system.

        (ICFRE funded project)

Achievements :

  1. Established Sissoo-zea mays system as an OSR trial at TFRI campus- by doing cultural operation like ploughing, weeding and manuring of the experimental plot of two year old Dalbergia sissoo plantation which were established in 21 plots ( size 10m x 10m) at 3 different spacings of 4m x 4m, 5m x 5m and 6m x 6m  and  3 plots were kept as blank outside the plantation area.
  1. Data on growth and yield of both agriculture as well as tree crops were recorded and data indicates that maximum yield was found in the spacing of 5m x 5m for the agri-silviculture system.

PROJECT 3 : Sustainable Development of  new Bamboo Agroforestry techniques for increased income generation in the Central Indian States. (NBM funded project)

Achievements :

  1.  Two bamboo species like Bambusa nutans  and  Dendrocalamus strictus were  selected for bamboo based  Agri-silviculture system. So far two agriculture crops viz. wheat in Rabi season and Urad in Kharif season were intercropped  with these bamboo species.
  2. Motivated farmers of  Gwalior and Chhindwara districts of Madhya Pradesh  and Raipur  and Devpur of  Chhattisgarh  through training and distribution  of seedlings towards adoption of bamboos in their field.
  1. Successfully established bamboo-wheat and bamboo-urad Agri-silviculture system as an OSR.
