Response of nitrogen and phosphorus on pointed gourd (Trichosanthes dioica Roxb.)

An experiment was conducted at horticulture farm, RRS, Agwanpur, Saharsa to find the effect of N and P2O5 on Pointed gourd (Parwal). Present study shows that the improvement in yield was due to increase in fruit length, fruit number and fruit length, fruit number and fruit weight under the influence of N and P2O5. Results shows that 50 Kg N/ha and 75 Kg N/ha was equally effective for this trait. Similarly, 30 kg P2O5/ha increased the fruit yield per plant in comparison with no application of P2O5. 15 kg P2O5/ha and also 30 Kg P2O5/ha and 45 kg P2O5/ha were on per for yield per plant. This showed that N and P2O5@ 45 kg /ha and 30 kg/ha, respectively, proved beneficial in increasing fruit yield as compared to their higher levels.
