From the above experimental finding it was be concluded that the Hybrid NBH-842 was statistically significant and higher in terms of growth parameters like vine length, earliness in flowering and maturity and variety NBH-842 yield parameters like fruit weight and fruit yield per vine while NBH-Manvi plus for fruit length, fruit diameter, and fruit yield per vine. Hybrid Prasad-100 showed best performance for quality parameters including TSS and Vitamin C content.
