The number of parameters and training time of the competing methods for crop yield prediction.

Measures	Models
	Ridge	Lasso	RF	DFNN	RT	3D-CNN	YieldNet
Number of parameters	8641	8641	Non-parametric	923,882	Non-parametric	3,167,490	1,436,050
Training time (min)	0.42	1.94	155.14	31.46	1.44	759.4	2.89

The training time indicates the total time needed for training models for both corn and soybean yield prediction. The models were trained on an Intel i7-4790 CPU 3.60 GHz.
