Fig. 6: Apparent effects of irrigation and planting data on rice NUE.
From: Data-driven strategies to improve nitrogen use efficiency of rice farming in South Asia
a,b, Effect of number of irrigations (a) and transplanting date (b) on rice NUE. Each grey dot represents the Shapley value for an individual field, with positive values indicating a positive impact on predicted NUE (shaded green) and negative values indicating a negative impact on predicted NUE (shaded red). See Methods for details regarding these Shapley values. The black line displays a trendline fitted to the data. Vertical x ticks represent the sample density. Irrigation data were unavailable for Bangladesh’s floodplains; hence, relationships are not shown in a. See Supplementary Information 6 for variable definitions.
