The experiment carried out to find out the “Impact of mulching materials and fertigation levels on papaya (Carica papaya L.) cv. Red Lady under protected cultivation was carried out at the Instructional Farm (Horticulture), Career Point University, Alaniya, Kota during 2024-2025. The experiment was laid out in Factorial Randomized Block Design with thrice replication including twelve treatment combinations, comprising like Factor- A treatments N and K % is F1-120 %, F2 100%, F3-80%. Factor -B split treatments S1-10 and S2-20 Factor -C M1- Organic mulch and M2- Black polythene mulch

The application of fertilizer on productivity was found most effective improve in papaya crop. The highest plant height (115.41, 153.13 and 190.84 cm), leaves was found to be maximum (31.62, 55.13 and 65.97) at 150, 200 and 250 DAT, fruit weight was found to be maximum (1.09 kg), fruit yield per plant found to be maximum fruit (22.79 kg/ plant, total soluble solids was found to be higher (10.70 0brix), maximum ascorbic acid (41.26 mg/100g) under all treatment F2 (fertilizer level 100%).

Fertilization split significantly height growth period on all the observation the increase in plant height was found to be maximum (115.11, 156.66 and185.68 cm), number of leaves was found to be maximum (28.54, 50.60 and 64.53), at 150, 200 and 250 DAT The maximum fruit weight (0.980 g), fruit yield maximum (20.14 kg/plant) maximum total soluble solids (10.05 0brix), ascorbic acid was found to be maximum (38.06 mg/100g), were observed in Fertilization split 20

The use of black polythene in plant height was found to be maximum (123.81 cm) at 150DAT, number of leaves maximum (27.85 and 49.88 at 150 and 200 DAT be maximum fruit weight 0. 980 kg), under treatment M2 (Black polythene mulch). The fruit yield was found to be maximum (19.84 kg/plant), maximum total soluble solids (10.03 0brix), maximum ascorbic acid (37.62 mg/100g) under treatment M2 (Black polythene mulch).
