A field experiment was conducted during Zaid-2017 and 2018 to study the “Effect of integrated nutrient management on plant growth improvement of ridge gourd.” at Horticulture farm, SKN College of Agriculture, Jobner, Rajasthan. There were twenty four treatment combinations replicated thrice in a randornized block design. The result of the experiment showed that the plant growth of ridge gourd was significantly increased with integrated use of manure, fertilizers and bio-fertilizer. Integration of vermicompost with inorganic fertilizers and microbial inoculants has efficiently contributed in mineralisation of unavailable forms of nutrient to the available form. The results revealed that the vines of ridge gourd fertilized with 100% of RDF of NPK + vermicompost @ 8.3 t/ha and Azotobacter + PSB recorded maximum vine length, number of branches per plant, leaf area and total cholorophyll content alongwith early initiation of first female and male flowers and maximum number of female and male flowers per vine.Hence, the above integration is essential for improving growth parameters of ridge gourd grown in sandy loam soils of Rajasthan.
