Separating the impacts of crop diversification and rotations on risk (2001, methodology): “The diversified system is rarely practiced and can be were caused by low yields resulting from abnormally low precipitation (Varvel, 2000).considered artificial.”
Temporal Yield Variability under Conventional and Alternative Management Systems (2007, background): “To reduce the effects of variability on crop production, many growers rely on external inputs of fertilizers, pesticides, and tillage (Varvel, 2000).”
Crop Diversification for Improved Weed Management: A Review (2021, background): “Crop rotation is the practice of growing a series of crops sequentially over time on the same land, thus providing temporal variability [48].”
Wheat improves nitrogen use efficiency of maize and soybean-based cropping systems (2015, background): “…al., 2005; Meyer-Aurich et al., 2006a), decrease in yield potential and increased yield instability (Grover et al., 2009; Katsvairo and Cox, 2000; Lund et al., 1993; Meyer-Aurich et al., 2006a,b; Singer and Cox, 1998; Smith et al., 2008; Stanger and Lauer, 2008; Varvel, 2000; Yamoah et al., 1998a).”
