An experiment was carried out to study the growth, yield and cost economics of papaya (Carica papaya L.) cv. Red lady as influenced by different irrigation and fertilizer levels. This experiment was conducted at PFDC (Precision farming development centre), Department of Horticulture, UAS, GKVK, Bengaluru during 2018-19 and 2019-20. The experiment was laid out with twelve different treatments replicated thrice. The spacing followed was 1.8 m x 1.8 m. The highest yield parameters under protected and open conditions revealed that, significantly the highest yield per plant (77.70 kg) and yield per hectare (239.77 tons) was achieved under protected conditions, while an average yield of 39.64 kg per plant and 122.32 tons yield per hectare was obtained under open field conditions with the same irrigation and fertilizer levels @ 50%, 80% and 100 % E pan (mm/day) + 125 per cent recommended dose of fertilizers. The highest cost benefit ratio in papaya cv. Red lady grown under open filed condition was 1:2.35 with the application of 50%, 80% and 100% E pan (mm/day) + 125 per cent RDF, whereas, for every one rupee invested the cost benefit ratio was to the extent of 1:3.03grown under naturally ventilated polyhouse structure, whereas the least vegetative, yield parameter and also lesser cost benefit ratio was observed in T1 - I1F1 30%,50% and 60% E pan(mm/day) +75 % RDF at 90, 180, 270, 360, 450 and 540 days after transplanting under open field and protected condition respectively.
