Abstract
A field experiment was conducted to study the response of bajra hybrid (ABH-1) to spacing and nitrogen levels
in alfisols of scarce rainfall zone under rainfed conditions during kharif, 2015-16 at Agricultural Research Station,
Ananthapur. The experiment was laid out in Factorial Randomized Block Design and replicated thrice. The results
revealed that bajra sown at 60cm x 15cm produced higher growth, yield attributes, yield and economics. Among
different nitrogen levels, application of 80 kg N ha-1 resulted in tallest plants and 60 kg N ha-1 produced higher dry
matter production. Application of 100 kg N ha-1 produced higher leaf area and leaf area index, yield attributes,
whereas, grain yield was higher with application of 60 kg N ha-1 and straw yield was higher with application of 80 kg
N ha-1. Higher gross, net returns and B:C ratio was recorded with application of 40 kg N ha-1 compared to 60, 80 and
100 kg N ha-1 which in turn comparable to each other
