RESEARCH ACHIEVEMENTS

Agrisilviculture

  • Hardwickia binata based agrisilviculture system developed and standardized for rainfed as well as irrigation conditions.
  • In Dalbergia sissoo based agrisilvicultural system under irrigated condition, blackgram and mustard yield was significantly better under deep ploughing as compared to normal ploughing.
  • At the age of five year, tree accumulated 34.50 t carbon/ha under naturally grown condition, 30.41 and 23.60 t carbon/ha under 50 and 70% canopy pruning in above and below ground biomass. N accumulation under 50%, 70% and naturally grown trees was 290, 222 and 325 kg/ha.
  • Three species of Glomus, two species of Acaulospora, three species of Gigospora and two species of Scutellospora were frequently recorded in rhizospheres of aonla, ber, chironji and laoda. Inter-cropping increased VAM activities in agroforestry systems in comparison to pure tree plantation.
  • Eucalyptus tereticornis based Agrisilculture, block plantation and boundary plantation showed significantly better above and below ground biomass in agrisilviculture than block plantation. Tree geometry had significant influence on growth and yield of intercrop wheat.
Agrisilviculture

Agrihorticulture

  • Aonla (Emblica ofiicinalis) based agroforestry technology standardised for the development of degraded lands of Bundelkhand region. Aonla varieties Kanchan and NA-7 have been identified highly renumerative as they have potential to yield 120 kg fruit /tree at the age of 10 years.
  • In-situ moisture conservation technique (stone mulching, deep basin, deep tillage+deep basin) significantly increased collar diameter of aonla plants and fruit yield. In 10th year of experimentation fruit yield ranged between 20.80 to 23.37 kg/plant under different conservation treatment against control (16.9 kg/tree).
  • Vegetative propogation technique of aonla through softwood cleft grafting on 5-6 months old seedling raised in polybags showed high establishment of plant on field transplant.
  • Bench grafting in aonla and ber, patch budding in bael and lasora and veneer grafting in chironji have been found highly successful.
  • In hortipasture studies, 12 fruit tree species were evaluated under natural pasture. Aonla, Mulberry, Lasora, Imli, Bael and Ber were found quite adaptive and feasible on the basis of survival, growth and yield.
Agrihorticulture

Silvipasture

  • Biomass production from degraded lands could be enhanced to 8-10 t/ha/year from 2-3 t/ha/year by introduction of leguminious trees, shrubs and herbs in natural rangelands.
  • Average daily gain in body weight of lambs and kids was higher (33 & 40%, respectively) under silvipasture system developed for semi-arid regions as compared to natural pasture during total grazing period of 478 days.
  • Evaluation of grazing on improved silvipasture system revealed that 5 goats and 5 sheeps /ha can be reared throughout the year. In addition, kids and lambs can be retained upto 6 months with satisfactory growth. The practice is economically viable.
Silvipasture

Tree Improvement & Silvipasture

  • Techniques for asexual propogation of high priority agroforestry species such as Anogeissus pendula, Hardwickia binata, Madhuca latifolia, Tectona grandis, Albezia procera, Bambusa spp., Morus species, Azardirachta indica, Albezia amara, Dalbergia sissoo and Mela dubia have been standardized.
  • Successful air layering in Hardwickia binata was achieved with 1000 ppm IBA + 500 ppm Kinetin + 50 ppm vitamin B complex resulting in 55% rooting during May. There was 100% survival in pots.
  • Anogeissus pendula was successfully regenerated through air layering with the treatment of 800 ppm IBA
  • Success achieved in propogation of Madhuca latifolia through air layering and stem cutting in the month of July and plants raised were successfully transferred to the field.
  • In Neem provenance trial, provenances of Dabra, Damoh, Shivpuri and Bhopal maintained their superiority over Jhansi since the establishment of trial (1994). progenies PT-6, PT-7, PT-15, PT-27 and PT-13 were performing well when compared to check i.e. Jhansi.
  • Out of 30 plus tree progeniesl of Dalbergia sissoo, progenies PT-2 and PT-6 proved thier superiority over check both in cultivated and degraded lands for growth and strightness.
  • 160 accessions of Jatropha and twenty seven sccessions of Karanj have been collected from different states of the Country and being evaluated for growth, seed yields and oil content at the Centre as well as farmers' field.
Tree Improvement

Social Sciences, Watershed & HRD

  • Studies on agri-horticultural system at farmers field with three fruit tree species namely Zizyphus mauritiana, Citrus aurantifolia and Psidium guajava at 6x6 m showed that yield of wheat was maximum in association with acid lime (2.2 t/ha) followed by Z. mauritiana (1.8 t/ha) and P. guajava (1.7 t/ha). The yield of groundnut was maximum in association with acid lime (0.4 t/ha) followed by Z. mauritiana and P. guajava. Fruit yield was maximum in Z. mauritiana (27.7 t/ha) followed by P. guajava and C. aurnatifolia.
  • Dynamic database on agroforestry/ forestry in India has been developed and named as "agroforestryBASE". agroforestryBASE is an independent module and the components include database management at the backend and application program at the front end.
  • In Research Projects Database, 199 agroforestry reasearch project covering 11 institutes and 25 agricultural universities have been entered. The database on MPTS (Multipurpose Tree Species) includes detailed information on 12 most important MPTS being utilised in agroforestry.
  • Field survey in Pratapgarh district of Uttar Pradesh indicated that area under aonla plantation increased with a linear trend and the production almost doubled in about a decade. The compund growth rate in the district was 4.02 percent with that of its production was 5.2 percent. The infrastructure for aonla industry in Pratapgarh district is encouraging with about 56 nursaries and 24 aonla processing units.
  • A watershed management programme has been initiated in Garh Kundar-Dawar, Dist. Tikamgarh (M.P.) on 850 ha area to demonstrate agroforestry technologies in participatory mode. Eight check dams were constructed to develop water resources. Marginal bunding of agricultural land (40 ha), gabion structures in 1st order stream (150 nos) were employed to check erosion.Agrihorticulture land use in 1.9 ha area on 5 farmers' field and live fencing on 1.7 ha are on 3 farmers' fiel were developed.
  • The Centre regularly organises Farmers' Day, Kisan Ghoshties to acquaint the farmers training with the current achievements on agroforestry.
