The experiment was laid out in RCBD considering eight treatments and three replication. The variety Pusa manjri was selected and the combinations of treatment were T₁= 40kg P/ha, T₂= 80 kg P/ha, T₃=20kg N/ha and 40 kg P/ha,T₄= 20kg N/ha and 80 kg /haP, T₅= 40kg N/ha and 40 kg P/ha, T₆= 40kg N/ha and 40 kg P/ha, T₇ = 60kg N/ha and 40 kg P/ha,; T₈= 60kg N/ha and 40 kg P/ha.

All the organic manures, 40kg/ha potassium and combinations of nitrogen and phosphorous were applied at the time of transplanting of bottle gourd in the plot according to the doses that is to be applied in the plot. On the basis of this experiment, it may be concluded that the application of nitrogen and phosphorous combination (60 kg N + 80 kg P per ha) increase the vegetative growth as well yield of bottle gourd. In treatment T₈the vegetative parameters like leaf area, average length of fruits, vine length, number of branches per plant, length of laterals branches shows positive response to the increasing nitrogen and phosphorous combination. It has also the positive impact on the reproductive attributes like Days to appearance of first female and male flower, number of female flower, umber of male flower and on the yield attributes of Pusa manjri variety of bottle gourd under the climatic condition of Kanpur. Therefore, it can be concluded that the increasing rate of nitrogen and phosphorous with the fixed proportion of potassium may increase the vegetative growth yield attributes as well the quality of fruits.

It is recommended to the bottle gourd growers for the application of combination of nitrogen and phosphorous for Pusa manjri variety of bottle gourd under which gives better growth and yield is (60 kg n + 80 kg P per ha) for higher production to bottle gourd under Kanpur condition.
