Nitrogen (N) is a key nutrient for cotton cultivation, directly affecting growth, yield and quality of production.
Importance of nitrogen in cotton
Nitrogen contributes to leaf area growth, increases plant height and has a positive effect on the yield of sown cotton. However, excessive or inappropriate application can lead to negative consequences such as excessive vegetative growth at the expense of fruit set or increased susceptibility to disease.
Application time of nitrogen
Before or at sowing (basal fertilisation):
Purpose: To ensure sufficiency during the early stages of plant growth.
Quantity: Usually 10-12 units of nitrogen per acre, combined with phosphorus and potassium, are applied.
Period before or at the appearance of the combs (surface fertilization):
Purpose: To cover the increased nitrogen needs of the plant during the period of intensive vegetative growth and fruiting.
Quantity: Surface fertilisation covers about 50-60% of the total nitrogen needs.
Total nitrogen needs
For an expected yield of about 400 kg of sown cotton per hectare, the total nitrogen needs are between 15-20 kg per hectare.
NEOGRAN
NEOGRAN by ZIKO S.A. is a complex granular fertilizer with boron, ideal for the basic fertilization of crops with oilseeds such as cotton. Its composition includes:
Total nitrogen (20%): a combination of ammonia (59%) and urea (41%) nitrogen for immediate and prolonged nutrition.
Phosphorus (8% P₂O₅): 93% water soluble, ensuring immediate absorption.
Potassium (10% K₂O): 100% water soluble, improving fiber quality.
Boron (0.3%): contributes to flowering and fruit setting. Total sulphur (30% SO₃): improves the availability of other nutrients.
Instructions for applying NEOGRAN to cotton
Basic fertilization: apply 30-40 kg per acre before or at sowing, incorporating the fertilizer into the soil.
The use of NEOGRAN ensures the supply of essential nutrients to cotton, supporting healthy growth and achieving high yields. For more information, visit the NEOGRAN page.
