Effect of integrated nutrient management on economics of herb production in lucerne

Abstract

The experiment was conducted to study the effect of integrated nutrient management on economics of herb production in lucerne (Medicago sativa L.) at the farm field of Krishi Vigyan Kendra, Konehalli, Tiptur Taluk, Tumkuru District during kharif and rabi seasons with nine treatments and four replication. The results revealed that the maximum fresh herb yield per hectare at first (193.52 q & 178.70 q), second (207.41 q & 213.89 q), third (209.26 q & 217.13 q), fourth (210.65 q & 218.98 q), fifth (211.11 q & 216.20 q), sixth (210.18 q & 208.33 q) and seventh harvest (208.33 q & 200.00 q) were recorded respectively during kharif and rabi season and also maximum net return (Rs. 1,38,270 ha-1 & Rs. 1,38,675 ha-1) and B:C ratio (2.743 & 2.749) were obtained respectively during kharif and rabi season with the application 50 % RDF + 25 % N through vermicompost + Rhizobium + PSB + VAM.
