The estimation of horizontal and vertical airflow resistance is essential for fabricating storage cum curing structure for multiplier onion. The horizontal and vertical airflow resistance of multiplier onion (var. CO-4) was investigated at three different moisture levels of 80.8, 84.2, and 88.8% w.b., and the airflow rates varied from 1 to 1.7 m3 s−1 m−2. The horizontal airflow resistance was studied at three different depths of fill of 10, 20, and 30 cm. The resistance of multiplier onion to airflow increased significantly with increasing depth of fill, moisture content, and airflow rate. Models, namely Shedd's, Hukill and Ives equation, were investigated to explore the horizontal airflow resistance of onion. Shedd's equation was found to be the most suitable model with a high coefficient of determination and low RMSE value. The vertical airflow resistance was studied at a depth of fill of 5–15 cm and spacing between racks of 20–40 cm. The airflow resistance may be best expressed by the linear model with the highest adjusted R2 of .842 and a predictedR2 of .8053. The optimum curing conditions were obtained at an airflow rate of 1.15 m3 s−1 m−2, 14.5 cm depth of fill, and 35 cm spacing between racks.
