Research : Crop improvement activities in rice at ARS, Mannuthy resulted in the release of four rice varieties viz., Hraswa, Ahalya, Manupriya and Manuratna suited to Kole lands and other areas of rice cultivation. Manuratna is a short duration rice culture developed through reselection in rice variety Hraswa, maturing in 95-100 days. Average yield recorded by the culture is 5.6 t/ha with high per day productivity and is suitable for all the three seasons of Kerala. This culture is of much importance in the present situation of water scarcity, where very early varieties can act a pivotal role.

Other cultures in pipe line are E39 and E 56-2 in the early duration group and Cul. 6-08 and Cul.2-08 in the medium duration group. Aromatic varieties collected from different parts of India were evaluated at this station to find out aromatic varieties suitable for Kerala. Four varieties (Pusa Sugandh-2, Pusa Sugandh-4, Sugandhamati and Rasacadam) were identified to have high yield potential of above 5 t/ha with good aroma, milling and cooking qualities. Variety Hraswa is further refined to Hraswa-I, HS-13 & HS-16

Transfer Of Technology : The performance of the coconut hybrid, Kerasree produced by Kerala Agricultural University and Kerasankara produced by CPCRI are highly appreciated by farmers and they are in high demand in Thrissur and neighbouring districts. The above coconut hybrids are produced on farmer participatory activity and being sold to the farmers, under RF mode. About 25,000 hybrid seedlings are distributed annualy.

Farm Trials and Demonstration plots of different rice varieties and cultures were conducted in farmers’ fields at different locations throughout Kerala.

In rice the seeds of Hraswa and Manurathna were produced under farmer participatory mode and being sold to farmers.





Research : A state plan project entitled “Kole Land Crop Productivity Centre” and “Crop Security Intelligence Wing Centre” were completed in Kole Lands of Thrissur. The project aimed at monitoring of soil, plant, water, atmosphere and biotic changes with respect to time and season of planting and making concurrent changes. Paddy was raised in the project area and soil changes and plant growth were monitored in relation to different cultural operations like land preparation, weed control and water management. Another work in kole lands is studies on secondary and micronutrient deficiencies and their amelioration. Works on standardization of agro technologies for precision farming and validation of organic farming techniques are going on. 

Transfer Of Technology : A state plan project 'Kole Land Crop Security Intelligence Centre' completed. The project aimed at transfer of proven technologies to the Kole land farmers. Fifteen Kole land crop security Intelligence personnel deployed for the purpose, conducted keen observations of the field, soil and water and made timely  reporting of important changes if any. This facilitated providing early warnings on pest and disease problems so that farmers can take immediate steps to protect the crop. The project is continued as Pest and Disease surveillance and management in Kole lands and Strengthening Research in Kole Lands. An automatic weather station was also installed in Kole lands as part of the project.

The CSIW Officers regularly visited the paddy fields and recorded soil, crop, atmosphere and water related parameters with respect to pests, diseases, physiological disorders, soil and water quality parameters. Based on the analysis, they reported the conditions as well as provided technical messages to farmers on tackling problems. Due to frequent visits and interventions by CSIW Officers, an awareness could be created among farmers regarding the misuse of poisonous pesticides and to go for a safe crop production without using high quantity of pesticides. Farmers reduce unscrupulous use of pesticides and fungicides and non judicial use of chemical fertilizers due to their intervention in Kole lands. This also enabled us for the grass root level understanding of the constraints in Kole land cultivation and to come out with management and technical outputs to overcome these situations.

The Project "Rain Water Harvesting" is aimed at increasing the water availability of farm by introducing bunding, trenching, terracing etc. Soil is also conserved. The programme seems as a good demonstration piece to visiting farmers and students. The organic farm also attracts many visitors.

The scientists work as advisory committee members of research scholars.

Provides technical consultancy for ATMA, Kole Land Development Agency, Command Area Development Agency etc.

RKVY Project on “Enhancing Rice Production in Kerala and attaining partial Self Sufficiency” was also undertaken by the station with the objectives of monitoring and analysis of plant productivity under double cropping w.r.t. change in climate, soil and region in Kole lands, developing management options at macro level towards sustaining high productivity in Kole lands and providing service support system for farmers for sustained cultivation of Kole lands through the services of Food Security Army.
