Abstract:
Aims: To evaluate the “Correlation and Regression Studies of Growth, Yield Attributes and Yield of foxtail millet (Setaria italica L.) Under Different Varieties and Landraces”. Place and Duration of Study: The experiment was carried out in the Rabi season of 2022-23 at Experimental farm in Karunya Institute of Technology and Sciences, Coimbatore. Experimental field was silty clay loam in texture with medium in available N (273.0 kg/ha), high in available P2O5 (21.5 kg/ha) and high in available K2O (425.0 kg/ha) and lower level of organic carbon (0.29%). Study Design: Randomized Block Design (RBD). Methodology: The treatments consisted of 8 foxtail millet varieties and landraces viz., T1 - ATL-1 (Control), T2 - SiA-3222 (Garuda), T3 - SiA-3088 (Suryanandhi), T4 - SiA-3085, T5 - SiA-3156, T6 - SiA-3233 (Reynaudu), T7 - Mookanthathinai and T8 - Koranthinai. Results: Grain yield was highly significant positive correlation with N uptake (r = 0.996**), DMP at harvest stage (r = 0.984**), K uptake (r = 0.981**), P uptake (r = 0.966**) and straw yield (r = 0.954**). From the regression, N uptake (R2 = 0.993**), DMP (R2 = 0.968**) at harvest is the important positive component of grain yield in foxtail millet followed by K uptake (R2 = 0.962**), P uptake (R2 = 0.934**) and straw yield (R2 = 0.911**). Conclusion: From the result of correlation and regression, it was concluded that in terms of grain yield, the foxtail millet varieties and landraces are influenced by the DMP at harvest stage, N uptake, K uptake, P uptake and Straw yield.
