The nutrient release rate in nano fertilizers can be controlled as per environmental conditions like soil moisture percentage, temperature fluctuations and soil acidity level to effectively increase the efficiency of nutrients for plant growth. An experiment was conducted during the year 2021 to find out the best combination in nano nitrogen, nano Zn and nano Cu on certain growth and yield characters of ridge gourd (Luffa acutangula L.) cv. COH 1 at Chidambaram,Tamil Nadu, India. The data collected for the growth and yield parameters were put through to analysis of variance for randomized block design (RBD). The treatments were scheduled as follows: T1–100% RDF, T2- 50% RD-N+100% RD-P+100% RD-K+nano N, T3–25% RD-N+100% RD-P+100% RD-K+nano N,T4–T2+nano Zn (a)+nano Cu (a), T5–T2+nano Zn (b)+nano Cu (a), T6–T2+nano Zn (a)+nano  Cu (b), T7–T2+nano Zn (b)+nano Cu (b), T8–T3+nano Zn (a)+nano Cu (a), T9–T3+nano Zn (a)+nano Cu (a), T10–T3+ nano Zn (a)+nano Cu (b) and T11–T3+nano Zn (b)+nano Cu (b). The results generated from the experiment were statistically significant (P≥0.05) for all the growth and yield characters recorded. The combination of 50% RDF with nano nitrogen @ 2.5 ml, nano zinc @ 4 ml and nano copper @ 4 ml was observed to be significantly superior over other treatments. It recorded profuse growth and yield in respect of maximum vine length (9.69 m), number of primary branches (7.87/vine), number of leaves (251.65/vine), number of fruits (26.60/plant), fruit length (52.36 cm) and fruit weight (472.74 g) were found significantly superior over all the other treatments. This study identified that the combined application of 50% RDF along with nano nitrogen, nano zinc and nano copper had significant influence on certain growth and yield characters on ridge gourd.
