Multicote Agri reduced N application rate in Greenhouse Tomatoes

37.5% reduction in N application resulted in a slight and insignificant reduction in total yield, protein content and net income

 

Crop/cultivar

Tomato (greenhouse) / Hazera-189 (for fresh consumption)
Country / location Israel / southern part, Besor farm / July – December, 2005
Objectives Find optimal application rate of Mgro for highest total - and marketable yield with less labor and mineral fertilizers application, under this specific loamy-sand soil
Haifa product tested Multicote Agri 16-8-26 (90-0-100, % coated) (6M)
Application method Banding at 10 cm depth and 20 cm to the side of the line of plants
Tested treatments Control: A
A: Nutrigation of liquid NPK fertilizers at 660-240-840 kg/ha of N-P2O5-K2O, by drip irrigation at 2-days intervals throughout the growth cycle

Multicote Agri B - Multicote Agri 16-8-26 (90-0-100, % coated) (6M) 
1650 kg/ha (49-55-51% of commercial applied N-P2O5-K2O respectively)

Multicote Agri C - Multicote Agri 16-8-26 (90-0-100, % coated) (6M) 
2700 kg/ha (65-90-83% of commercial applied N-P2O5-K2O

Multicote Agri. D- Multicote Agri 16-8-26 (90-0-100, % coated) (6M) 
3750 kg/ha (91-125-116% of commercial applied N-P2O5-K2O

Conclusions 30% coating was superior to 70% coating, implying that the higher the avaliblitiy of N, the higher the productivity of the plants

37.5% reduction in N application by applying Multicote agri. resulted in a slight and insignificant reduction in total yield, protein content and net income
