Fig. 1From: Chickpea shows genotype-specific nodulation responses across soil nitrogen environment and root disease resistance categoriesChickpea shoot dry weight and soil N environment account for the number of nodules per plant. Linear regression plot of shoot dry weight (DW) for the six genotypes of chickpea grown with three levels of available N (HN (paddock soil + N), MN (paddock soil—N) and LN (sand:soil 2:1)) as predictors of the numbers of nodules per plant, r2 = 71.9, standard error of observations 9.97Back to article page
