A field experiment was conducted during summer (zaid) 2015 at Department of Horticulture, MJRP College of Agriculture & Research, MJRP University Jaipur (Rajasthan). The experiment consisted of eight treatments. Results of field experiment revealed that the minimum days (39.73) required to opening flower from sowing were recorded under application of 90 kg N + 60 kg P2O5 + 60 K2O ha-1, followed by application of 90 kg Nitrogen ha-1 (41.22 days), whereas the maximum days (44.21) were noted under absolute control. Whereas, Plant height was recorded the maximum under application of 90 kg N + 60 kg P2O5 + 60 K2O ha-1, after 40 days (28.10 cm), 60 days (75.40 cm) and 80 days (106 cm) and seed germination (91.96 %). Amongst fruit characters the maximum length of fruits (13.93 cm), diameter of fruits (2.6 cm), fruit yield plant-1 (258.18 g) and number of fruits plant-1 (30.54) were recorded under application of 90 kg N + 60 kg P2O5 + 60 kg K2O ha-1. The maximum yield (172.12 q ha-1) was obtained under application of 90 kg N + 60 kg P2O5 + 60 K2O ha-1 followed by application of 90 kg N +60 P2O5 ha-1 (163.12 q ha-1) and the maximum number of seeds fruit-1 was recorded (56.46) under application of 90 kg N + 60 kg P2O5 + 60 K2O ha-1. Application of 90 kg N + 60 kg P2O5 + 60 K2O ha-1 recorded significantly higher net returns (123084.10 Rs ha-1) and B: C ratio (2.13) which was found statistically superior over other treatments.
