Action Research on Energy Pillars Technology: This Technology is an customised technology for improved management of Fruit Orchards so as to enhance their productivity. The Centre has initiated Action Research adopting Energy Pillars Technology (EPT) for Citrus rejuvenation in which hands on demonstrations and trainings were conducted in different District covering 21 villages from 12 Blocks. About 315 farmers have been capacitated on the technology.
Action Research on Azolla as Biofertilizer for Paddy Cultivation: Azolla is a tiny fresh water fern commonly found in ponds, ditches and rice fields. It has been used as a biofertilizer for rice. Azolla is not popular to the rice growers in Meghalaya although it was found in many paddy fields across the State.
The Centre is conducting action research on propagation of Azolla as well as on-field trials of Azolla for improving productivity of Paddy.
Samples of Azolla were collected from paddy fields located at Nongjrong, EKH District and Liarkhla, Ri Bhoi District. They were multiplied and maintained at BRDC Experimental Farm, Laitmynsaw for generation of mother cultures. About 500 Kg of Azolla has been produced and distributed to different farmers across the State for trials. The final result is expected after harvest which will take place during October and November.

3. Action Research and on Farm Trials of Tomato (Laitkynsew Variety) at Mawlyngbna Village: Trial on propagation of the indigenous Tomato variety is being conducted in Mawlyngbna Village, Mawsynram Block, East Khasi Hills District. During the initial year, about 10 g seed had been introduced in which 1.4 quintal of the tomato was harvested.

4. Action Research on Bio-inoculants and Bio-control Agents: The Centre has taken up on-Lab production of Bio control agents, Bio-pesticide and Bio-fertilisers since 2014 as part of the sustainable green technologies programme to promote and adopt Green Integrated Pest Management (IPM) to the Farming communities. The following Bio-pesticides, Bio-fertilisers and Bio control agents are being produced and carried out in the Laboratory.
i)Bio-Pesticides: Trichoderma viride
ii)Bio-Fertilizers: The following types of biofertilizers are being produced in the laboratory:
a. Phosphate solubilising biofertilizers (PSB) eg. Bacillus and Pseudomonas
b. Plant growth promoting biofertilizers eg. Pseudomonas fluorescens
c. Nitrogen fixing biofertilizers eg. Rhizobium, Azospirillum
d.Phosphate mobilizing biofertilizer eg. Mycorrhiza
iii)Bio-Control Agents: Biological control is the use of natural enemies (called biological control agents) to reduce populations of pests such as insects and weeds. Trichogramma is being propagated/produced in the Centre as Tricho-cards.
