CHOW CHOW (Sechium edule)
Two types: Green fruited and White fruited.
Requires well drained acidic soil with a pH of 5.5 - 6.5 and thrives best in a temperature range of 18 - 22°C and at an altitude of 1200 - 1500 m. In plains it comes up well during winter season.
Planting is done during April – May
Preparation of field
Dig pits of 45 cm x 45 cm x 45 cm at a spacing of 2.4 x 1.8 m and fill up the pits with 10 kg of FYM, 250 g of urea, 500 g of Super phosphate and 500 g of Muriate of Potash.
Fully matured and sprouted fruits collected from high yielding vines are planted in pits @ 2 – 3/pit.
Weeding is done as and when necessary. At initiation of vine growth, stake the plants. Provide pandal at a height of 2 m. Prune the plants to ground level during winter from second year after planting.
In hills, pruning is done during January. Apply 250 g of urea for each vine after pruning and at the time of flowering.
For controlling scales, mealy bugs and aphids spray Dimethoate 30 EC @ 1 ml/lit.
1. Collect the damaged fruits and destroy.
2. The fly population is low in hot day condition and it is peak in rainy season. Hence adjust the sowing time accordingly.
3. Plough the field to expose the pupae.
4. Use polythene bags fish meal trap with 5 g of wet fish meal + 1 ml. Dichlorvos in cotton 50 traps are required/ha, fish meal + Dichlorvos soaked cotton are to be renewed once in 20 and 7 days respectively.
Vectors can be controlled by spraying Dimethoate 30 EC 2 ml/lit or Methyl demeton 25 EC 2 ml/lit thrice at fortnightly intervals.
About 25 - 35 tonnes/ha can be obtained.
