Bray has modified the mitscherlich equation to
A. G = f (x1, x2, x3 . . . . . . . . xn)
B. $$\frac{{{\text{dy}}}}{{{\text{dx}}}} = \left( {{\text{A}} - {\text{y}}} \right){\text{C}}$$
C. Y = A (1 - 10-cx)
D. log (A - y) = log A - C1b - cx
Answer: Option D
Solution(By Examveda Team)
The equation introduced by Mitscherlich has been generally used to express nutrient-yield relationships as follows: $${\bf{y = A}}\left( {{\bf{1 - }}{{\bf{e}}^{{\bf{ - eb - ex}}}}} \right)$$Bray has modified the mitscherlich equation to $${\bf{log}}\left( {{\bf{A - y}}} \right){\bf{ = logA - }}{{\bf{C}}_{\bf{1}}}{\bf{b - cx}}$$
Where A = % theoretical maximum yield, y = actual yield obtained in q ha-1, b = native soil test value in kg ha-1, x = fertilizer nutrient applied in kg ha-1, c1 and c = constants i.e., the efficiency of soil and fertilizer nutrients respectively.
