IDENTIFICATION, ISOLATION AND MULTIPLICATION OF HIGH YIELDING PLANT PROPAGULES
  • Superior phenotypes of non wood forest produce like Tamarindus indica, Azadiracta indica, Terminalia chebula, Emblica offcinalis, Sapindus emarginatus and bio diesel species like Jatropha, Derris indica have been identified through genetic combing.
  • Vegetative propagation like air layering, grafting, rooting of sprigs etc standardized.
  • 300 Malis trained in clonal multiplication technology.
  • 150 mist tents erected for Macro propagation.
  • Plus trees in species, Casuarina equisetifolia and Casuarina junghuniana have been identified for maximum bio mass production per unit area. Plus trees speceies, Teak, Melia dubia have also been identified for the producation of good quality of timber in short duaration.

PACKAGE OF PRACTICES FOR DIFFERENT SPECIES
To find out optimum cost effective package of practices for some fast growing economically important tree species such as:
Species Name Species Name Species Name
Swietenia macrophylla Casuarina junghuniana Bambusa balcooa
Eucalyptus tereticornis Casuarina equisetifolia Bambusa tulda
Dalbergia latifolia Atrocarpus integrifolia Bambusa nutans
Acacia hybrid Alstonia scholaris Bambusa vulgaris
Melia dubia Pterocarpus santalinus Melocanna baccifera
--- --- Thyrostachis oliveri
 
Different treatments with different pit sizes namely 45 cm3, 60cm3 ,80cm3 and 1m3 were adopted with and without appropriate bio-fertilizer doses. Planting techniques such as peripheral planting in 3m dia saucer, trench planting in tapering trenches, planting in the centre of saucer etc. were also tried for the above species. After four years it was found that the treatment of planting nine plants in periphery of three meter dia saucer in 45cm3 pit with application of bio-fertilizer produced maximum survival compared to the rest of the treatments. The treatment namely 1m3 pit with bio-fertilizers produced better results for the production of maximum bio-mass.
Similar package of practices experiments were carried out for the following species at different agro climatic zones.
Species Name Species Name Species Name
Bambusa balcooa Albizia richardiana Bambusa mukalba
Bambusa nutans Acacia hybrid Kaya senegalensis
Simaruba glauca Lannea coromadelica Eucalyptus Species
Jatropha curcas Casuarina junghuniana Acacia auriculiformis
Cassia siamea Delonix elata ---

STANDARDIZATION OF BIO-FERTILIZER PACKAGE FOR DIFFERENT PIT SIZES

Different bio-fertilizers namely vermicasting, VAM, Phosphobacter, Azospirillium were applied in three different doses for different pit sizes of 30cm3, 45cm3, 60cm3, 80cm3 and 1m3 for the following species and was compared with the controlled conditions.

Species Name Species Name Species Name
Acacia auriculiformis Ailanthus excelsa Melia dubia
Jatropha curcas Eucalyptus tereticornis Kaya senegalensis
Terminalia chebula Albizia lebbeck ---
Different doses of bio fertilizers has been standaradized for different size of pits is as follows
Pit Size 45cm3 60cm3 80cm3
Vermicasting 200g 500g 1kg
VAM 25g 50g 100g
Phosphobacter 10g 20g 25g
Azospirillium 10g 20g 25g
Tricoderma viridii 5g 10g 15g
Pseudomonas 5g 10g 15g
Standardizing Biofertilizer dose for different pit sizes with height variation in Neem.
STUDY ON SUITABLE MULCH MATERIAL
An attempt was made to identify cost effective, suitable mulch material for Simaruba glauca. Mulch material like saw dust, Casuarina needles, wood shavings, polymer, paddy chaff, etc., were applied to 3-4 inches thickness upto one feet radius around each plant.
Soil samples were collected at 60cm depth, before and three months after mulching and soil moisture % was tested and compared.
