Figure 2. Effect of P supply on root-shoot ratio (cm root/ g shoot) pot-1 of safflower and sunflower in sandy soil and loamy soil. For a given species and a given soil type, means within each column followed by the same capital letter are not significantly different. * indicates significant difference between the two columns at each P supply (A and B) or a given plant species (C and D) at the same P level. P< 0.05, n=3
