Parthenocarpic cucumber crop was fertilized with 125% of RDF application along with 7 days of interval, which improves growth parameters like plant height, number of primary, internodal distance, stem girth, leaf area and total chlorophyll content, number of fruits per plant, weight of fruit and fruit diameter under naturally ventilated polyhouse conditions. Significantly higher number of primary branches plant-1, number of fruits plant-1, fruit yield plant-1, fruit yield plot-1, fruit yield ha-1 were observed with application of 125% RDF 7 days of intervals upto 90 DAT. The improvement in quality parameters were also recorded with application of 125% RDF with 7 days of intervals upto 90 DAT. Available soil nutrient status in post-harvest soil samples were comparably found maximum than initial soil samples.
