Testing the difference between limiting yields in quadratic fertilizer response curves

Testing the difference between limiting yields in quadratic fertilizer response curves

Agronomy Journal 73(1): 136-138

The limiting yields of fertilizer response curves are necessary for comparisons of fertilizers and for estimating their availability coeff. A statistical procedure to test the difference between limiting yields of 2 quadratic response curves is presented. The test was contingent to the assumption that the estimated nutrient rates corresponding to the limiting yields were constants.
