Abstract :

Sesame is one of the oldest and most important oilcrops as main crop and second crop agriculture. This study was carried out to determine the effects of irrigation and nitrogen levels on physiology of summer sesame; var. AKT 101 was conducted at Agronomy Department Farm, Dr. Panjaao Deshmukh Krishi Vidyapeeth, Akola during summer season of 2012. Experimental results revealed that some growth parameters like AGR (Absolute growth rate for height and dry matter) was significantly higher with irrigation scheduling at1.0 IW/CPE (Irrigation water amount/Cumulative pan evaporation) at 45 to 60 DAS, NAR (Net assimilation rate) was highest with treatment 0.8 IW/ CPE ratio (Irrigation water amount/Cumulative pan evaporation) at 60 to 75DAS and RGR (Relative growth rate for dry matter (g g–1 day–1)) was highest with treatment 0.4 IW/CPE ratio at 30 to 45 DAS. And all this growth parameters using for growth analysis found significantly higher with nitrogen application at 90 kg N ha–1. Over rest of the combinations except in RGR it was found significantly higher with treatment 30 kg N ha–1 at 30 to 45DAS.
