Potato Production in Sri Lanka A.G.C.Babu Deputy Director (Research) Agricultural Research & Development Centre Sita Eliya Sri Lanka
Sri Lanka Total area : 65,610km2 Major Agro ecological Regions: Dry Zone Intermediate Zone Wet zone Major Potato growing districts: Nuwara Eliya Badulla Major Seasons: Yala Maha Nuwara Eliya Feb. July Sept. – Jan. Badulla June – Sept. Oct. – Feb. ·Badulla ·Nuwara Eliya
Seed Potato Production Seed Requirement: 16,125mt DOA certified seed production: 10% Imported seeds: 10% Informal seeds: 80%
Tissue culture Laboratory • Capacity 100,000 in-vitro plants/year • Capable of meeting national demand • Net house • Limited capacity – 65m2 • 25,000 RSCC/month/variety • Polytunnels • 4000m2 • 14 mt/yr Facilities Available for seed production
Informal Seed Production No proper seed production A portion of ware potato Introduced Quality seed production by providing G0 Technologies adopted by the Research Station Repeated harvesting techniques: Soilless growth media 30-40 tubers/plant Aeroponic: 80-100 tubers/plant Hydroponic: 80-100 tubers/plant
seed • High cost • Poor quality • Limitations in seed production beyond G3 • Limitations in seed production of new, better varieties • Limited Land for seed production • Limitations in storage facilities • Short term storage • long term storage • storage management Constraints
Use of modern technologies for high quality seed production. • Provide high quality seed producing units • Develop new varieties suited to different agro ecological regions of Sri Lanka. Objectives
Production of virus free potato mother plants - in-vitro techniques • Use of biotechnological tools for virus indexing & diagnosis of other disesases • Modifications to existing hydroponic system to increase productivity • Testing & implementation NFT culture • Development of well-organized seed supply chain through farmer organizations Activities
Monitoring and diagnosis of major diseases & insects in seed production sites • Certification of seed potato production • Trainings (Local & Foreign) • meristem culture and rapid propagation of virus-free plantlet • G0 production technology based on the culture medium; hydroponic and aeroponics • standard cultivation technology for seed potato; • late blight forecasting techniques; • winged aphid monitoring technology • certification system for informal seed potato; • demonstration of standard cultivation techniques ….contd
demonstrations for farmers • G0 production • Field multiplication of G0 • Storage • Facilitate farmers with necessary inputs • Construction of Hydroponic system • Providing storage facilities • Adaptability testing of new varieties • High yielding & Blight resistant • Heat tolerance ….contd
Increase capacity of G0 production • Free availability of G0 • Training farmers on G0 production • Awareness programmes – Importance of high quality seed • Research activities for • Productivity increment • G0 production of different varieties • Efficient techniques for disease diagnosis • Commercial scale G0 production Suggestions
Increased availability of quality seed potato • Increase national average productivity from 17.5t/ha to 20t/ha • Strengthening informal seed production • Towards self sufficiency in ware potato Project Impacts & Recommendations
Establishment of village level G0 production units • Increase G0 production from 1mn to 2mn tubers Future Plan
