ABSTRACT

Field experiment was conducted at Regional Agricultural Research Station, Nandyal during post rainy season (maghi), 2015-16 to study the response of white sorghum to irrigations and nitrogen levels. The results of the experiment revealed that higher values for growth parameters viz., plant height and number of green leaves per plant were recorded with two irrigations. However, as regards the dry matter production, at 30 DAS, there was no significant difference among irrigation levels but at 60 and 90 DAS significantly higher dry matter was produced with two irrigations than no irrigation. Higher number of grains per panicle, grain weight per panicle, grain and stover yield was recorded higher with two irrigations where as 1000 grain weight was non significant with irrigations. All growth and yield parameters, grain and stover yield was higher with the application of 180 kg N ha-1 and lower values were obtained with the application of 90 kg N ha-1.
