“…), the plant biomass increased with fertilizer rates up to 200 kg NPK ha -1 but above this a reduction in biomass was observed. The result agreed with earlier reports that biomass yield increased with fertilizer application up to a certain optimal limit (Bradley et al, 1976;Shukla and Gupta, 1980;Almishaal et al, 1984;Alwan, 1986;Al-Mukhtar et al, 1987).…”

“…This created a technical problem for maintenance and mechanization of pumpkin production. The extensive foliage covering though genetic was enhanced by fertilizer application due to the fundamental involvement of NPK in the large number of enzymatic reactions as well as other metabolic, energy transfer and biological processes which hasten cell division and growth in plants (Al-Mukhtar et al, 1987). Similar results were obtained in the application of NPK fertilizer to Philodendron domesticum L., Cordyline terminalis and Codiaeum variegatum (Zaghloul et al, 1996;Atta-Alla et al, 1996;Reem, 1997).…”

Pumpkin (Cucurbita pepo L.) young leaves and vines are consumed as vegetables among the rural dwellers in Southwest Nigeria. It is a cheap source of protein, vitamins, fibres and antioxidants in their diet. Due to the intensive cultivation of available lands which affects the nutrient status of most soils and their productivity, the need to apply fertilizer on pumpkin became pertinent. Therefore, nitrogen, phosphorus and potassium (NPK) fertilizer influence on biomass accumulation in pumpkin was investigated for two consecutive seasons in 2010 at the Research Farm of Obafemi Awolowo University, Ile-Ife, Nigeria. NPK (15:15:15) compound fertilizer was applied at the rates of (0, 50, 100, 150, 200 and 250 kg ha-1) to C. pepo at 2 weeks after planting (WAP). At 8 WAP, the following morpho-physiological traits: vine length, vine diameter, number of internodes, internodes length, vine weight, number of leaves, total fresh and dry biomass assessed were significantly influenced by season and fertilizer effects. The combined analysis of variance (ANOVA) results showed that the effects of season (S) and fertilizer (F) are significant effect on all the traits. Season effect showed that the early season was better (p = 0.05) while the application of fertilizer beyond 100 kg of NPK per hectare was not statistically beneficial for biomass yield and its components. However, the significant S X F interaction on the total dry matter fitted well into a quadratic equation with significant R 2 values. The response curves showed higher response to fertilizer in the early than late planting season and a maximum biomass yield was attained at the application of 205 kg and 244 kg ha-1 of NPK (15-15-15) for early and late season cultivations, respectively.

“…Application of N, P and K has been reported to increase the growth and productivity of pumpkin and crops generally (Al-Mukhtar et al, 1987;Kumar et al, 1995). Mobile phosphorus and potassium have also been reported to be very important for the setting, development and storage of pumpkin (MacCarthy et al, 1990).…”

“…According to Gupta et al, (2021), boron application at a rate of at 2.5kg ha -1 is necessary to produce boron adequacy in soil. Abd El-Aal et al, (2010) and Al-Mukhtar et al, (1987) discovered that a foliage spray of urea and amino-vitiplus improved squash plant growth and fruit yield. This impact was less than that obtained when urea was applied, but it was greater than that obtained when amino-mix was applied.…”

Study was conducted In RCBD Design with three replicates to examine the impact of nitrogen application methods on the growth and yield of ridge gourd, evaluating 06 treatments comprising of various soil and foliar-applied N combinations. The following treatments were used: T1=Control (no N applied to the surface, no N applied to the leaves): T2=N at 75kg ha-1 through soil; T3=N at 75 kg ha-1 through soil+foliar urea at 1.5% concentration; T4=N at 75 kg ha-1 through soil+foliar urea at 3.0% concentration; T5=N at 100 kg ha-1 through soil; T6=N at100 kg ha-1 through soil+foliar urea at 1.5% concentration;T5=N at 100 kgha-1through soil+foliar urea at 1.5% concentration; The findings showe that various nitrogen application approaches had a major impact on all of the ridge gourd parameters calculated in this analysis (P0.05).
