Abstract

                                An experiment was conducted at the Agricultural Research Station, Bhavanisagar. during summer and at Agricultural College and Research institute, Coimbatore during kharil season of 1978 with sunflower (variety EC 68413) with six irrigation treatments in main plots and four phosphorus levels in sub-plots. The results indicated that irrigation and phosphorus significantly influenced the LAI and CGR, but the effect on NAR and RGR was not significant. Irrigation at 1.05 IW/CPE ratio with 90 kg/ha of phosphorus recorded highest LAI and CGR in all stages of observation.
