Two errors introduced during composition are being rectified herein.
The note to Table 1 erroneously defined “qt” as quart, while it should be quintal. The table with the revised note is below:
Table 1. Economic Data for Crops and Crop Production Functions in Case Study 1 (Data from Kumar and Khepar 1980)
CropCrop price (Rsqt1)Crop total fixed cost (Rsha1year1)Crop production function

Paddy89.02,439.68Y=5.93840.035206W+2.412043W0.5

Note: qt = quintal; Rs = Indian Rupee; W = depth of irrigated water (mm); Y = crop yield (qtha1).

On page 04016025-6, in the paragraph below Eq. (16), the third line included an extraneous “$”. It should read, “crop j (AU$ kg−1); CFIXj = fixed annual cost of crop j.”
ASCE regrets these errors.
