Intensive tillage practices demand more resources, damage soil quality, and reduce crop yields and profit margins. Crop diversification along with conservation agriculture (CA)-based management practices may reduce external input use, improve resource-use efficiency, and increase the productivity and profitability of intensive cropping systems. A field study was conducted on loamy soil in a sub-tropical climate in northern Bangladesh to evaluate the effects of three tillage options and six rice-based cropping sequences on grain, calorie, and protein yields and gross margins (GM) for different crops and cropping sField crops research108791https://www.ebi.ac.uk/biostudies/studies/S-EPMC9846111biostudies-literatureReduced tillage and crop diversification can improve productivity and profitability of rice-based rotations of the Eastern Gangetic Plains.PMC9846111Hoque MATimsina JZiauddin MATMKrupnik TJGathala MKHossain MfalseReduced tillage and crop diversification can improve productivity and profitability of rice-based rotations of the Eastern Gangetic Plains.Intensive rice (<i>Oryza sativa</i>)-based cropping systems in south Asia provide much of the calorie and protein requirements of low to middle-income rural and urban populations.
