Abstract

A field experiment was conducted at The College of Agriculture farm, Raichur on medium black soil during kharif,2021 to study the effect of date of sowing, row spacing and fertilizer levels on yield and economics of Kodo millet(Paspalum scrobiculatum L.) The results revealed that, early sowing during first fortnight of July recorded higher ear headweight (9.69 g), ear head length (6.41 cm), test weight (5.93 g), grain yield (2147 kg ha-1), straw yield (3701 kg ha-1), grossreturns (`87732 ha-1), net returns (`57008 ha-1) and B:C (2.85). However, sowing during second fortnight of July wasfound to be on par with first fortnight of July. Among fertilizer levels and row spacing, application of 125 % RDF with45 cm row spacing recorded significantly higher ear head weight (8.78 g), ear head length (6.18 cm) and test weight (5.52 g).Whereas, treatment receiving 125 % RDF with 30 cm row spacing recorded significantly higher grain yield (2164 kg ha-1),straw yield (3772 kg ha-1), gross returns (` 88443 ha-1), net returns (`56857 ha-1) and B:C (2.81)
