Abstract

To study the effects of different substrates on the growth, development, yield and economic efficiency of Holland F1 Fadia cucumber variety planted at Hong Duc University, the experiment was designed in randomized complete block (RCBD) with 4 treatments and 3 replicates in Winter season 2018: 1) Treatment 1 (control): 10% surface soil + 50% coir + 20% pig compost + 10% rice husk ash + 10% rice husk; 2) Treatment 2: 20% surface soil + 40% coir + 20% pig compost + 10% rice husk ash + 10% rice husks; 3) Treatment 3: 30% surface soil + 30%o coir + 20%) pig compost + 10%) rice husk ash + 10% rice husks; 4) Treatment 4: 40% surface soil + 20% coir + 20% pig compost + 10% hun husk + 10% rice husk, with one cultivar of cucumber (Fadia Fl), The results showed that the substrates including 30% surface soil + 30% coir + 20% manure + 10% rice husk ash + 10% rice husk was suitable for the growth and development of cucumber plants, which had the highest tolerability, highest theoretical yield, highest real yield, achieving 53,43 ton/ha, highest profitsing attain 289,93 million dong/ha with good quality,
