Abstract: The effect of seed priming practices on growth, yield and economics of maize under rainfed conditions in south east Rajasthan on a clay loam soil was studied with various treatment seed priming treatments in kharif. Results reveals that, seed priming with KH₂PO₄ @2% for 6 hours recorded significantly higher maize grain yield (3059 kg ha^-1) followed by with K₂SO₄ @2% (3025 kg ha^-1) which were 24.15 and 22.75 percent higher over no priming (2464 kg ha^-1), respectively . The net monitory returns under these treatments were also obtained higher (Rs 50542 ha^-1 and Rs 50584 ha^-1, respectively) with benefit cost ration (3.07 and 3.05, respectively). Similarly, KH₂PO₄ @2% recorded highest RWUE (5.036 kg grain ha^-1 and Rs.69.75 ha^-1 per mm rainfall). Seeds primed with KH₂PO₄ @ 2% for 6 hour was significantly increased plant height (8.7%), dry weight of plant (41.5%), number of grains per cob(15.5%), cob length (17.69%), grain weight per cob (19.05%) and test weight (12.6%) in comparison to no priming.
