(During the Period of 2019-2023) 

  1. Forty nine native ornamental species collected from BR hills under Tribal plan project were established at filed gene bank (Conservatory) ICAR-IIHR in the shade net House. And all the plants are adapted to Bangalore conditions. They are maintained evaluated and multiplied.
  2. Based on the nutrient uptake studies we have standardized dose of fertilizers with drip irrigation and mulching is as follows. Marigold: Recommended dose of NPK for 95: 75:170 kg NPK/Ha.Nutrient requirement of marigold was in the order of K > Ca > N > Mg >P>S>Fe>B>Mn>Zn>Cu.
  3. China aster: Recommended dose of NPK for China Aster  is 180 / 50/ 190 kg /Ha.Nutrient requirement of China aster was in the order of N >K > Ca>P > Mg> S > Fe >Mn > Zn> Cu. With this 20 % of water and 25%o of nutrient saving can be achieved
  4. Identification of Pollutant absorbent ornamental shrubs/trees as a cost- effective means to mitigate air pollution by assessing Air pollution Tolerance Index using the total ascorbic acid content, total chlorophyll content, leaf extract pH and relative water content in the leaves of tree/shrubs. A total of APTI of 80 different trees and shrubs of Bengaluru city was estimated along with dust accumulation and carbon stock data. Information on root depth of all the trees under study was also reported in order to choose for different locations of the city. And documentation about the biodiversity supported by these trees was also prepared. This information will be very much use full for all developmental agencies of city administration.

 

Varieties / Technologies Developed: 

 

Technology: Holistic soilless growing system was developed called ARKA Growing System of Vertical Garden for foliage plants (Chlorophytum comosum, Sanseveria trifasciata, Syngonimum podoplryllum white and Peperomia obtusifulia for growing foliage plants) in vertical gardens. The whole package is cost effective which would have the actual cost Rs 580/sq.feet compared to commercial package (Rs 1300 to 20,000/ sq.feet).

Arka urban HortiKit

Product: To meet the needs of the urban population with the objective of converting barren terraces and backyards into multifunctional gardens, We have come out with Arka Urban HortiKit. The kit contained seven of the institute's released technologies, including Ark fermented Cocopeat, flower and vegetable seeds, bio pesticides, and a consortium.
