Statistical Assessment of Different Ways of Calculating Land Equivalent Ratios (LER) [PDF]
Experimental Agriculture, 1982 SUMMARYThe use in analysis of variance of six different ways of calculating the Land Equivalent Ratio (LER) was assessed. Criteria used are (1) normality of the residuals of LER values after fitting block and treatment effects, (2) precision of comparisons arising from the analysis of variance, and (3) possible bias in the means. These were examined in

Agrociencia, 2022 The historical milpa has contributed to food security of small farmer families due to its biodiversity. The objective was to evaluate indicators of food access [basic food baskets (BFB), minimum wages (MW) and real food security index (RFSI)], Land Equivalent Ratio (LER), and maximum net income (NI) obtained from the polyculture of native maize-husk ...
