Harvesting of Oil Palm- An Ambitious task behind Ag. Engineers By KusumaGuturu, II M.Tech, Dept. of Farm machinery & Power, Tamil Nadu Agricultural University, Coimbatore.
Oil palm(ElaeisguineensisJacq) • It is a tree without branches but with many wide leaves at its top • Native – West Africa • Cultivable area under oil palm: 15 million ha. (2009) • Area under oil palm (2009 – 10): 1,55,203 ha • India – 80% in A.P. and Karnataka • Economic life span: 25 – 30 years • No . of plantations : 140 – 150 per ha • Planting procedure: staggered • Plantation starts to produce fruits after 3 – years
According to world trade journal…. • Global production of oils & fats – 30% (48 million tonnes) • Global consumption – 25% • International trade in veg. oils - 60% • Thrives well at • 29° – 30°C (max) • 22° - 24°C (min) • Rain fall: 2500 – 4000 mm • Humidity: >80% • Sunshine: not <5 h/day • Soils: moist, deep, loamy and alluvial • Height : 7 – 13 m • Diameter: 45 – 65 cm • Fruit bunch weight: 15 – 25 kg • Duration of harvesting: 10 – 15 days • Problem statement
Institutes working on the problem: • DOPR • CIAE • TNAU • MOPB • State Agricultural universities

Conclusions: • The manual harvesting of oil palm has its own difficulties even though energy requirement for harvesting is reduced by ergonomic refinement of the machines. • The other harvesting equipments like cantas tool, pneumatic cutter, lifting platform perform better than the manual harvesting, but they have drawbacks of less reach of height, high initial investment, inquisitive in operation. • The harvesting Robot is good substitute for all these machines and to achieve all these objectives. The research towards agricultural robotics need to be focused to achieve these ambitious goals in oil palm harvesting
