The experiment was carried out at Dr.YSRHU- Regional Horticulture Research Station, Lam, Guntur - 522034, Andhra Pradesh from September 2024 to May 2025 Factorial Randomized Block Design comprising fifteen treatment combinations replicated thrice with two factors i.e., nutrients levels at three viz., 75% RNP, 100% RNP, 125% RNP and foliar nutrition at five levels i.e., foliar nutrition each sprayed at (75, 100 and 125 DAP). All the parameters pertaining to growth, yield were recorded and analysed as per the standard procedures. Among nutrient levels 125% RNP (N3) performed best with respect to growth, yield, viz., plant height (102.40 cm), number of branches per plant (15.31),number of fruits per plant (210.02), fruit yield per plant (164.63 g), fruit yield per hectare (44.41q/ha), Fruit length (12.41 cm). Among foliar nutrition F4 (Nano Urea + Nano DAP @ 5 mL L⁻¹) foliar nutrition each sprayed at 75, 100, 125 DAP performed best with respect to growth, yield parameters, viz., plant height (104.80 cm), number of branches per plant (15.37), number of fruits per plant (217.01), fruit yield per plant (180.89 g), fruit length (12.77 cm), fruit yield per hectare (47.11 q/ha), Among the interaction (N3F4), 125% RNP (Nano Urea + Nano DAP @ 5 mL L⁻¹) foliar nutrition each sprayed at 75, 100, 125 DAP shows best results in plant height (109.43 cm), number of branches per plant (15.62 cm), Fruit length (13.33 cm), and (N2F4) 100% RNP (Nano Urea + Nano DAP @ 5 mL L⁻¹) foliar nutrition each sprayed at 75, 100, 125 DAP shows best results in number of fruits per plant (228.23), fruit yield per plant (198.93 g), fruit yield per hectare 49.79 q/ha).
