Achievements & Honours 21 Honours

As PI technology generated and included in the package of practices for Horticultural crops of Assam (2010-19)

1. Spindle rot (Phytophthora sp) of coconut seedling: Drenching of Bordeaux mixture (1%) in the coconut nursery bed immediately after the seedling emergence and continued based on disease pressure.

2. Management of stem bleeding (Theilaviopsis paradoxa) of coconut Scrape or chiselling out of the infected portion followed by wound dressing with tridemorph (1 ml/l) or carbendazim (1 g/l) and finally application of hot coal tar

3. Management of sclerotial wilt (Sclerotium rolfsii) of tuberose Dipping of bulbs in the solution of captan (0.3%) for 30 minutes before planting followed by soil drenching with captan (0.3%) @ 10 litre/m2 at monthly interval for three months Alternatively, pre-planting dipping of bulbs in the solution ( 10 g/l) of Trichoderma viride followed by soil application of T. viride @ 100 g/ m2 after mixing with FYM (1:10) at the time of planting

4. Management of leaf spot (Alternaria polyanthi) of tuberose Spraying of chlorothalonil or Iprodione(25%) + carbendazim(25%) (Quintal) @ 0.2% (2 g/l) or carbendazim (0.1%) at 10 day interval.

5. Management of leaf and flower blight (Alternaria dianthi) of marigold  Low temperature coupled with cloudy weather and continuous dizzling for more thane 2 days have a significant role in the epidemiology of leaf and flower blight of African and French marigold caused by Alternaria dianthi.Necessary prophylactic measure should be adopted in anticipation of such weather conditions. Three sprays with Mancozeb (0.25%) at 10 days interval will manage the disease  Routing Spraying of Mancozeb (0.25%) at 30,40 and 50 days after transplanting will will effectively protect the African and French Marigold from the disease.

6.Leaf blight of tuberose: Spray difenoconazole (0.1%) or iprodione + carbendazim (0.1%) or azoxystrobin (0.1%) at 7-10 days interval, starting the first spray at the appearance of disease symptom.

As Co-PI technology generated and included in the package of practices for Horticultural crops of Assam (2010-19)

7.Standardization of bio-fertilizer doses in dendrobium orchid:1. Standardization of bio-fertilizer doses Bio-fertilizer source of Azospirillum and Phosphobacterium each of 2g per plant at two months interval along with a regular spray of NPK ( 20:10:10) @ 0.2% twice a week has been found promising for growth and flower production in Dendrobium Var. Sonia.

8. Recommendation for tuberose germplasm: Hybrid Shringar and Prajwal have been recommended for commercial cultivation of Assam

9. Recommendation for gladiolus germplasms: Variety Red Candiman,White Prosperity,Novalux,American Beauty,Red Sea,Suryakiran,Tiger Flame and Dhanawantry have been recommended for commercial cultivation in Assam

10. Recommendation for tuberose germplasm: Considering the Benefit Cost Ratio GK-TC-4, Phule Rajani and Hybrid Arka Nirantara (single type) were recommended for commercial cultivation in Assam for their special features.

11. Micronutrients in gerbera: Manganese Sulphate @ 0.8% may be sprayed thrice in a crop cycle, at 45, 60 and 75 days after planting for better crop growth, flower quality and yield in field grown gerberas.

12. PHT on Anthurium: Considering the cost effectiveness of the different chemicals, post harvest treatment on anthurium flower spathe either with 50 ppm of Sodium hypochlorite plus 5% sucrose or 300 ppm of aluminum sulphate plus 5% sucrose have been found promising for better standing of vase life at consumers level.

13. Recommendation non Heliconia: Considering the market acceptability and gardeners choice Red Heliconias, shrimp heliconia (Heliconia pendula ) Bihai Yellow Dancer and Bihai Orange Dancer were recommended as cut flowers and border planting as shrubberies for commercial cultivation in Assam.

14. Weed management in gladiolus: Application of Atrazin @ 1.5 kg a.i./ha and Metribuzin 0.25 kg a.i/ ha Have been recommended for controlling weeds in gladiolus.

15. PHT on Gerbera: Tartaric acid 300 ppm alone and in combination with 2% sucrose solution or Aluminum Sulphate 300 ppm alone and in combination with 2% sucrose solution have been recommended as promising holding solution for extension of vase life of cut stalk of gerbera Cv.Red Monarch

16. Gerbera under Polu house condition: Considering the performances of various flower and sucker yield attributing characters the variety Renee, Sonata Tecta,Salvador, Shimmer, Pink Elegance & Destina have been recommended for growing under poly houses under Assam condition

17.PHT on Orchids: A holding solution containing 50% coconut water, 4% sucrose and 0.2%sodiumhypochlorite (NaOcl) significantly increased economic and total vase life in Dendrobium orchids

18. Tintin in tuberose: Tinting dip cut ends of tuberose spikes harvested at 2-3 buds open stage in the synthetic food dyes viz,. Respberry Red,Bright Blue and Orange Red @8% concentration for one hour for uniform tinting of petels.
