Soil –

  • It is grown in variety of soil but deep alluvial, sandy loam soil and black soil having good drainage are ideal for doing sapota farming.
  • pH having 6.0-8.0 is optimum for sapota farming.
  • Avoid cultivation in shallow clayey soil and in high calcium content.

Climate – 

  • Sapota, being a tropical crop can be grown from sea level upto 1200 m. above m.s.l.
  • It needs warm (10-380 C) and humid climate (70% relative humidity) for growth and can be cultivated throughout the year.
  • Coastal climate is best suited for its cultivation.

Time of sowing:

  • Planting is mainly done in February to March and August to October month.
  • The ideal season of planting is June to December
  • Grafted on Manilkhara hexandra (Pala) rootstock.

SAPOTA APPROACH GRAFTINGDSC02231

  • For sapota farming, well prepared land is required.
  • To bring the soil to fine tilth, ploughing is done 2-3 times followed by leveling. 

Spacing

  • 8 x 8 m (156 plants/ha) for conventional planting.
  • Adopt high density planting at 8 x 4 m (312 plants / ha) for high productivity 
  • Planting
  • Dig pits of 1 m x 1 m x 1 m size and fill up with top soil mixed with 10 Kg of FYM, 1 Kg of neem cake .
  • Plant the grafts at the centre of the pit with ball of earth intact.
  • The graft joint must be atleast 15 cm above the ground level. 
  • After planting stake the plants properly to avoid bending or damage to graft joint during heavy winds.
  • Legumes and short duration vegetable crops may be raised as intercrop during pre-bearing stage.
  • Raising of intercrop serve as additional income and enriches the soil fertility by fixing the atmospheric nitrogen.
  • Depending upon climate and irrigation facilities, intercropping with pineapple and cocoa, tomato, brinjal, cauliflower, peas, cucurbits, banana, papaya can be done.

 

 

Pre emergence application of Stomp@800ml/acre or Diuron@800gm/acre is done for initial 10-12 months for the effective weed control.

  • Harvesting is done in July-September month.
  • But keep in mind not to harvest unripe fruits.
  • Mainly harvesting is done when fruits are having to fade orange or potato color and fruits having a less sticky milky color product and it is gets easily plucked from the tree.
  • Mainly 5-10 years old tree gives 250-1000 fruits.
  • After harvesting, grading is done and then storage is done at 20 C temperature for a period of 7-8 days.
  • Storage life can be increased for 21-25 days by removing ethylene and adding CO2 @5-10% in the storage atmosphere.
  • After storage packing is done in cardboard boxes and is used for long distance transportation.
  • February – June and September – October.
  • Ripen the fruits in air tight room by keeping a beaker containing 5000 ppm Ethrel + 10 g NaOH pellets in an air tight chamber (5 ml Ethrel in one lit of water is 5000 ppm).
  • Alternatively, fruits can be exposed to ethylene gas at 100 – 200 ppm for 18 – 20 hrs to induce ripening.
