43. Chinese varieties of rice have a short cycle, which means that they grow fast, in 4 months.
In regions where there is water all the year round, 2 crops can be grown each year.
If you want to plant 1 hectare of rice field, sow a nursery of 400 square metres.
Sow 12 kilogrammes of seed per 100 square metres. Apply fertilizers to a nursery of 100 square metres as follows:
1.2 kg of ammonium sulfate
1.5 kg of superphosphate of lime
1.7 kg of potassium chloride.
Transplant when the seedlings are 2 weeks old. Plant 4 to 5
seedlings per seed hole.
Leave 25 centimetres between rows and 25 centimetres between seed holes.
· Fertilizing and weeding.
After your first weeding, for every hectare of rice field apply:
100 kg of ammonium sulfate 50 kg of superphosphate of lime 35 kg of potassium chloride.
After your second weeding, for every hectare, apply:
200 kg of ammonium sulfate
100 kg of superphosphate of lime 65 kg of potassium chloride.
The seedlings are planted further apart; therefore more weeds will grow. You must weed often.
