Experimental conducted aimed to entitle “Comparative Study of Irrigation and Fertigation Strategies on Performance of Papaya (Carica papaya L.) Under Shade Net House” was carried out at the Agriculture Farm (Horticulture), Career Point University, Alaniya, Kota during 2024-2025. The experiment was laid out in Factorial Randomized Block Design three replication with 09 treatment combinations, comprising like Factor- A treatments isI₁- Drip Irrigation IE/CPE- 0.4 ECP, I₂Drip Irrigation IE/CPE- 0.6 ECP, I₃- Drip Irrigation IE/CPE- 0.8 ECP. Factor -BRDF is F₁-60% RDF through fertigation and F₂-80% RDF through fertigation and F₃- 100% RDF through fertigation.

The application of irrigation on productivity was found most effective improve success all parameters of papaya. Plant height was found to be maximum (113.71, 154.90, 199.58 cm), maximum number of leaves (33.10, 54.28 and 68.78), The maximum number of fruit (20.24 fruit per plant), The maximum d fruit weight (0.910 g) Fruit yield was found to be maximum (18.42 kg /plant) Highest TSS (11.20 ⁰brix) and the ascorbic acid was found to be maximum (44.95 mg/100) under treatment I₃ (Drip Irrigation IE/CPE- 0.8 ECP).

Fertilization RDF significantly height plant height was found to be maximum (114.95, 151.04 and 203.90 cm) number of leaves be maximum (30.64, 52.70 and 66.85), Number of fruit was found to be maximum (19.46 fruit per plant), fruit weight maximum (0.877 g), Fruit yield be maximum (17.07 kg/plant) Fertilization RDF significantly height plant height was found to be maximum (114.95, 151.04 and 203.90 cm) number of leaves be maximum (30.64, 52.70 and 66.85), Number of fruit was found to be maximum (19.46 fruit per plant), fruit weight maximum (0.877 g), Fruit yield be maximum (17.07 kg/plant) TSS was found to be maximum (10.60 ⁰brix), ascorbic acid was found to be maximum (41.27 mg/100)under treatmentF₃ (100% RDF through fertigation).

Interaction effect of fertigation and RDF were recorded maximum plant height (125.33, 157.83 and 217.72 cm), highest number of leaves (34.85 and 57.54), maximum number of fruit (21.76), maximum fruit weight (1.07 kg), maximum fruit yield (23.28 kg), maximum TSS (11.66 ⁰brix) was recorded in (Drip Irrigation IE/CPE- 0.8 ECP+100% RDF through fertigation.
