Agronomy Division

Mandate of the Agronomy Division

To develop appropriate crop management practices and cropping patterns to realize higher productivity in different farming systems in the Dry Zone of Sri Lanka with  sustainable use of natural resources and effective management of abiotic stresses.


  1. Conducting training and awareness programs on following aspects
    • Agronomic management practices of OFC in different farming environments
    • Climate change impact on OFCs and mitigation  options
    • Potential for OFC cultivation in the dry zone
    • How to enhance productivity of OFCs
    • Productivity enhancement of different cropping systems
  2. Field investigations upon request by farmers or other stake holders to give recommendations on different field problems
  3. Technology dissemination through media and other campaigns like exhibitions

Research Areas

  • Biotic stresses due to water scarcity and high temperature.
  • Low productivity on rain-fed farming environments.
  • Poor soil fertility management.
  • Underutilization of cultivable lands.
  • High cost of production.
  • Crop diversification for food security and economic stability.
  • Yield optimization of new improved varieties through appropriate agronomic practices.
  • Suitable crop combinations for different cultivation environments.
  • Management packages for specific cropping environments.
  • Integrated soil nutrient management systems.
  • Identification of crop resilience and development of adaptation measures for climate change.


  • Integrated effect of mulching, deep ploughing and organic matter application was tested for chilli.
  • A feasibility study was carried out for big onion mother bulb production during off seasons in low rainfall areas during the late Maha season.
  • A demand driven Nitrogen application method was introduced for chilli.
  • Impact of canopy level temperature on pollen sterility of rice, soya and maize were studied under ambient conditions.
  • Impact of the high air temperature and the moderate moisture stress during anthesis on the canopy temperature, the pollen fertility and the spikelet fertility in Bg 366 and Bg 358 were studied.
  • A study on impact of organic mulches on big onion bulb production with paddy-husk, paddy straw, partially burnt paddy husk and gliricedia found that paddy straw mulch recorded the highest yield (38 t/ ha) with dark coloured bulbs.
  • In a study on the integrated effect of micro and macro nutrients and plant growth regulators on growth and yield of chilli found that there was no effect of micro nutrients when they were applied with organic matter. Although the growth was promoted by Plant Growth Regulators, no significant impact on yield was observed.
  • A new plant density recommendation (74 074 plants/ ha at 45 cm x 30 cm spacing with a proportionate increasing of N application).was given for hybrids under irrigated contion. The yield advantage was 20-25%.
  • Hybrid seed production technology was improved in maize by identifying appropriate bed types, plant densities and optimum flowering synchronization techniques.
  • The enhancement of drought stress tolerance in soybean crop by rhizobium inoculum used in Sri Lanka was identified.
  • Ideal initial seed moisture content, material used for storage and the location of the storage were identified for the enhancement of soy bean storage duration without decreasing the viability.
  • Dioscorea species with high yield potential under the dry zone conditions in Sri Lanka were identified.
