Formula for Calculating Yield Yield = ((May Rainfall x ) plus (June rainfall x -14.7) plus(July rainfall x 19.92) plus (August rainfall x 51.24) plus (September rainfall x ))
Formula for Calculating Yield Yield = ((5.34 x ) = plus (3.29 x -14.7) = plus(2.47 x 19.92) = plus (2.07 x 51.24) = plus (6.72 x ) = = Yield =
