Abstract

A field experiment was conducted at College of Agriculture Farm, Raichur on medium deep black soil during kharif, 2021 to study the effect of macro and micronutrients on nutrient uptake, yield and economics of teff (Eragrostis tef (Zucc.) Trotter). The results revealed that, application of 25:10:10 kg NPK ha-1 recorded significantly higher uptake of nitrogen (70.53 kg ha-1), phosphorus (19.97 kg ha-1), potassium (28.03 kg ha-1), grain yield (419 kg ha-1), straw yield (736 kg ha-1), net returns (Rs. 1,07,804 ha-1) and B:C (3.89). Among the micronutrients, combined application of ZnSO4 @ 5 kg ha-1 and FeSO4 @ 7.5 kg ha-1 recorded significantly higher uptake of nitrogen (59.39 kg ha-1), phosphorus (15.31 kg ha-1), potassium (23.45 kg ha-1), grain yield (361 kg ha-1), straw yield (602 kg ha-1) and net returns (Rs. 85,975 ha-1). The interaction effect of macro and micronutrients were non significant.

Conclusion

Application of 125 per cent RDF (25:10:10 kg NPK ha-1) along with combined application of ZnSO4 @ 5 kg ha-1 and FeSO4 @ 7.5 kg ha-1 recorded significantly higher nutrient uptake, grain yield, straw yield, harvest index, gross returns, net returns and benefit cost ratio. However, interaction effect of macro and micronutrients was found to be non significant with respect to yield and economics of teff.
