Optimizing Application of Phosphorus and Potassium to Processing Tomatoes under Drip Irrigation

IPNI-2007-CAN-ON28

The experiments will be conducted in a sandy loam soil with relative low soil tests for P and K at GPCRC, Harrow, ON. The treatments will include four fertilizer P rates ranging from 0 to 80 kg P ha-1, four fertilizer K rates ranging from 0 to 600 kg K ha-1, and two water management regimes including natural rainfall and natural rainfall enhanced with drip irrigation to best satisfy crop physiological needs in an optimum manner.

Interpretive Summary

Optimizing Application of Phosphorus and Potassium to Processing Tomatoes under Drip Irrigation in Ontario, 2009 Recent research has indicated that processing tomatoes require higher rates of N when grown with fertigation. The objective of this research is to determine optimum rates of P and K for the higher yields obtained in this production system.

Optimizing Application of Phosphorus and Potassium to Processing Tomatoes under Drip Irrigation in Ontario, 2008 Recent research has indicated that processing tomatoes require higher rates of N when grown with fertigation. The objective of this research is to determine optimum rates of P and K for the higher yields obtained in this production system.
