Varieties of Oil Palm:

1. Tenera: It is the hybrid type and widely cultivated
2. Dura: It has a thick shell and cultivated locally
3. Pisifera: It is fruit-bearing variety having no shell

Growth period and water requirement :

Stage of Growth
Parameter	Initial Stage	Crop Development	Mid-Season	Late Season	Growth Period
Oil Palm					Perennial Crop
Duration Days	60	90	120	95	365 Days
ETm ( mm )	Use appropriate values of Kc and ETo				2000-2500 mm/year
Kc 20% canopy	0.40	0.45	0.50	0.55	-
Kc 50% canopy	0.50	0.60	0.60	0.65	-
Kc 70% canopy	0.60	0.65	0.70	0.75	-

Drip System Recommendation From Premier Range:

Crop Spacing (m)	No. of plants/ha	Lateral Spacing (m)	Product Selection Premier Range	Emitter Discharge (1ph)	Emitters per plant Micro jets per plant
9 m x 9m (triangular)	143	7.79	ONLINE- TABE/ MICRO JETS	8lph/14 lph 40-60 LPH	6 2

Fertilizer Recommendation :

Oil Palm tree	N-P-K dose kg/ha
Farmyard manure	75 to 100 kg FYM or 90 to 100 kg of green manure applied 3 months after planting
Fertilizer Macro	N -First year 125 tons /year/ ha. Second-year, 250 tons/year/ha and 370 tons/ha/year after the third year P- First year 180 tons /year/ ha. Second-year, 360 tons/year/ha and 520 tons/ha/year after the third year K- First year 90 tons /year/ ha. Second-year, 190 tons/year/ha and 280 tons/ha/year after the third year
Fertilizer micronutrients	Magnesium and Boron are critical for Oil palm growth. Magnesium applies at a rate of 15, 30 and 45 tons/ha/year from 1st, 2nd and 3rd year onward. Boron 5, 10 and 20 tons/ha/year from 1st, 2nd and 3rd year onward.
