• Irrigation

  In the first year, irrigate on alternate days; from the second year until bearing, twice a week as needed. From the 5th year, the source gives a schedule by region and month. For example, in the eastern region for best yield: drip 80 litres/palm/day in March–September and 50 litres/day in October–February, with lower amounts for water scarcity. For drip, open four 30 cm pits 1 m from the trunk, place the dripper inside a slanting 40 cm PVC pipe so water drips 30 cm below the surface, and fill the pits with coir pith.

• Manures and fertilizers per palm

  From the 5th year, per palm per year: 50 kg FYM, compost or green manure; urea 1.3 kg (560 g N), superphosphate 2.0 kg (320 g P2O5) and muriate of potash 2.0 kg (1200 g K2O), in two equal splits in June–July and December–January. Apply in a circular basin 1.8 m from the base, mix in and irrigate; the soil must be moist at manuring. In the 2nd, 3rd and 4th years, smaller fractions of this dose are used (see the source for the exact fractions). Fertigation at monthly intervals with 75% of this dose is also given.
