Most Cultivated Field Crops in Irrigated Agriculture in Turkey
The most cultivated field crops in irrigated agriculture in Turkey primarily include rice, corn, sugar beet, potato, cotton, and sunflower.
Cereals (Grains)
Rice
Water requirement: it is 788-4355 mm
Fertilizer requirement: Fertilization is commonly practiced for nitrogen, phosphorus, potassium, and zinc elements, which are most deficient in rice production areas.
Phosphorus fertilizer should be at a dose that provides 5-6 kg of P205 per decare.
Potassium Fertilization should be at a dose that provides a few kg of K2O per decare.
Nitrogen Fertilization nitrogen amount varies between 15-18 kg/da.
Zinc Fertilization 4-5 kg of zinc sulfate is applied per decare.
Corn
Water requirement: it is 725 mm
The first water when the plant height is 40-45 cm, the second water at the tassel stage, the third water during the ear formation period, and the fourth water at the milk stage, and the water to be given in each irrigation is 100 mm.
Fertilization requirement:
Nitrogen fertilization 27-30 kg per decare
Phosphorus fertilization 10 kg per decare
Potassium fertilization 10kg per decare
Industrial Crops
Alfalfa
Irrigation requirement:
it is 1250-1300 mm.
Fertilization requirement:
Nitrogen fertilization 2-3 kg per decare
Phosphorus fertilization 14 kg per decare
Potassium fertilization 15–20 kg per decare
Sugar Beet
Irrigation requirement: it is 700 – 800 mm.
Approximately 100–130 mm of water is given with each irrigation.
Fertilization requirement:
Nitrogen fertilization 14–16 kg per decare
Phosphorus fertilization 10 kg per decare
Potassium fertilization 8–10 kg per decare
Potato
Irrigation requirement: it is 400 – 800 mm.
Fertilization requirement:
Nitrogen fertilization 15 kg per decare
Phosphorus fertilization 6 kg per decare
Potassium fertilization 8–10 kg per decare
Cotton
Irrigation requirement: it is 400-600 mm.
Fertilization requirement:
Nitrogen fertilization 8 -10 kg per decare
Phosphorus fertilization 4-5 kg pure phosphorus (25-30 kg super phosphate) per decare
Sunflower (oilseed)
Irrigation
requirement: it is 700-800 mm.
Fertilization
requirement:
Nitrogen fertilization
6-8 kg per decare
Phosphorus
fertilization 5-6 kg per decare
Potassium fertilization 6–8 kg per decare
