Effects of Salinity Sources on Growth, Physiological Process, Yield, and Fruit Quality of Grafted Rock Melon (Cucumis melo L.)

There is an increase in demand for high-quality rock melon the local market. Supplementing salt with a nutrient solution viable approach that can be implemented to improve fruit quality. Therefore, this study aims determine best treatment utilized quality without reducing growth, yield, and physiological process. The conducted by grafting (DAG) melon/bottle gourd at 18 days four sources of salinity: basic (BNS) (2.5 dS m-1), sodium chloride (NaCl) (50 mM) + BNS (7.1 potassium nitrate (KNO3) high strength (NS) m-1). plants were arranged randomized complete block design (RCBD) replications. Salinity induced using KNO3 sustained most growth variables, quality, relative water content, leaf gas exchange compared control. However, applying NaCl NS could sustain all processes components, such as total soluble solid sugar-acid ratio Fruit weight had reduced regardless salinity than those grown control their respective reduction 28.8%, 28.26%, 27.72%. To conclude, incorporating 50 mM feasible applied on grafted even though reduced. It due measured, capable sustaining processes, provides lower cost, easily accessible other salinity.
