Transforming Triple Cropping System to Four Crops Pattern: An Approach of Enhancing System Productivity through Intensifying Land Use System in Bangladesh

Table 6

Profitability of the four crops pattern over the existing pattern.

Cropping pattern	Gross return (Tk.·ha^−1)	Cultivation cost (TVC) (Tk.·ha^−1)	Marginal value (MVP) (Tk.·ha^−1)	Marginal cost (MVC) (Tk.·ha^−1)	MBCR
Mustard-onion/maize-T. Aman rice	539180	285542	147540	46894	3.14
