Oil Palm, India
Oil Palm, India
Oil palm was introduced in India as a small-holders irrigated crop in 1989 to meet the ever growing demand for vegetable oils. It serves as a marked variation from traditional oil palm areas such as Malaysia and Indonesia, where it is cultivated as a rain fed crop in large nucleus estates.
Small-holders irrigated crop
Inefficient use of water
Fixed duration of power supply
Coarse to medium textured soils
Leaching of nutrients
Low water and fertilizer use efficiency
Low FFB yields
Why drip is needed?
Economic importance of oil palm in meeting vegetable oil and biofuel demand.
To conserve water, increase water and fertilizer efficiency.
To optimized FFB and oil yields.

Agronomic and technical support
Crop water requirement and irrigation scheduling: Depth and frequency of water application; water quality consideration and measurement of applied water.
Fertigation scheduling: Soil and water analysis, estimation of nutrient dose, selection of fertilizers and compatibility, application skill via drip system, and foliar diagnosis for nutrient deficiencies.
System operation and maintenance: Pressure reading, valves operation, measurement of applied water. Cleaning of filters, fertilizer tank, acid treatment, chlorination, etc.
Training and capacity building: Soil water plant relationships, drip irrigation and fertigation principles, benefits, limitations and utility; water quality and herbicide usage.
Improved FFB yield: Conventional basin irrigation - 15 to 18 tons/ha and with surface drip yield has increased by 10% (20 tons/ha) in the first year and by 25% (25 tons/ha) in the second year after installing drip.
Water requirement and saving: Conventional basin irrigation – 1940 mm/year/ha and with surface drip – 1310 mm/year/ha. The water saving is 32% or 630 mm/year/ha. As an illustration, the saved water can irrigate 0.48 ha.
Economic indices: Internal rate of return (IRR) is 74%, payback period is four years and the net present value (NPV) is US$ 6034/ha
Additional benefits: Improvement in fertilizer use efficiency, management flexibility, less weed growth, and uniform irrigation of oil palm on undulated terrains.
Drip irrigation in oil palm is a technically feasible and economically viable technology.
Farmer is willing to expand drip irrigation to the remaining oil palm area.
Government subsidies of 50% on drip system cost for use in oil palm.
Oil palm best management practices: Drip Irrigation and fertigation scheduling.
