Table 9 Linear regression models of relationships (y = a + bx) between sesame yield parameters and inorganic N fertilizer application

From: Effect of manure sources and rates on nitrogen replacement value, sesame yield and nutrient content under drip irrigation system

Yield component Constant (a) Regression coefficient (b) r2 Probability Significance level
Seed yield (kg ha−1) 100.1 8.59 0.93 < 0.001 ***
1000-seed weight (g) No significant relationship     
Capsule no. plant−1 44.1 1.84 0.71 0.009 **
Branch no. plant−1 No significant relationship     
Plant height (cm) 101.4 0.605 0.89 < 0.001 ***
Seed oil content (%) No significant relationship     
  1. Application rates of inorganic N were: 0, 36, 72 and 108 kg N ha−1
