The current study was conducted during the 2019–20 kharif season at the Research Farm, College of Agriculture, OUAT, Bhawanipatna. To investigate the impact of calcium-based fertilizer on cucumber yield parameters, a total of seven treatments were employed in a Randomized Block Design (RBD) with three replications. When compared to RDF-only treatments, all of the treatments markedly increased cucumber growth, yield, and attributed attributes. When comparing the several treatments, the application of RDF + Calci-king @ 2 kg at 25 DAT and 40 DAT (T5) resulted with the highest plan height and flower setting

It is determined that applying RDF + Calci-king @ 2.5lit at 25 DAT and 40 DAT could result in increased cucumber growth characteristics and productivity. However, the application of RDF + Calci-king @ 2 kg at 25 DAT and 40 DAT resulted in a shorter time to blossom appearance (30.86 days). RDF + Calci-king @ 2 kg at 25 DAT and 40 DAT (T5) produced fruit with significantly higher yield metrics, including fruit length (16.04 cm), girth (13.62 cm), weight (154.92 g/fruit), and number of fruit/plant (16.95), as well as fruit yield (310.6 q/ha). This was statistically comparable to RDF + Calci-king @ 1 kilogram at 25 DAT, 2 kg at 40 DAT, and 2 kg at 60 DAT (T6) and RDF + Calci-king @ 2 kg at 25 DAT and 60 DAT (T7)
