Multicote Agri reduced N rate and applications

Multicote Agri reduced N rate and applications

 

19% reduction in the total applied nitrogen resulted in no yield reduction

 
 

Crop/cultivar

Maize

Country / location / date  France (south west), Dept. #31, Mr. Michel Pierre Cooperative Toulousaine de Céréales/ Summer 2002
Objectives

Maintain total yield with reduced N rate and less applications

Haifa product tested Multicote Agri 45-0-0 2 Months (25% coated + 75% uncoated urea)
Application method Top Dressing Banding at 10 cm under, and 20 cm to the side of the future line of plants
Tested treatment

Multicote Agri:
134 kg/ha of N as Multicote Agri  (80% of commercial N application) @ age of 4 leaves

Control:
60 kg/ha of N as TD of urea @ age of 4 leaves + 205 kg/ha of N as urea by TD @ age of 8 leaves

treatment results

Grain yield - (MT /ha)

Control – 14.3

Multicote Agri – 14.7

Conclusions A 19% reduction in N, all applied at the age of 4 leaves, by banding the CoteN close to the plants roots, has not caused any decrease in the yield. This represents a marked saving in both N fertilizer and application costs, as well as conforming with legal environmental constraints
