“…The results indicate that acidity increased with the increase in the dose of fertilizers, especially with potassium. These results are in confirmatory with the results of [17] who reported that high dose of potassium fertilizer have a positive significant effect on tomato fruit acidity, while it disagrees with that of [18], [19] and [15] who reported that low NPK mainly phosphorus will produce fruits with high acidity. Table ( Although there were differences between the two seasons in ascorbic acid content, the highest amount of ascorbic acid was found from the moderate treatment T 2 with organic (26.7 g N + 10.0 g P + 53.3 g K + 2kg organic / m 2 .)…”

2 ) in each group, the each of these was mixed with 2kg organic/m 2 , 2kg/m 2 organic alone and control (without fertilizer) used as a sub plot. Hybrids were assigned to be the main plots. The seedlings were transplanted on one side of 80 cm ridges and 40 cm plant spacing. The organic fertilizer was incorporated in soil before planting, whereas the NPK doses were added as powder weekly after two weeks from transplanting. Fruit quality was accessed as percentage of marketable fruits/m 2 , fruit diameter, total soluble solid "TSS", fruit acidity and ascorbic acid content. The means were compared using Duncan Multiple Range Test (DMRT) at P < = 0.05. The results showed that T 2 from NPK combination with or without organic fertilizer gave significant positive effects on all quality parameters tested in both seasons. The results also showed that there was no significant difference between the two hybrids in response to NPK combination with or without organic. The quality values were decreased with increased fertilizer dose above T 2 showing that excessive NPK fertilization (T 3 with or without organic) for high quality tomato under evaporative cooling system is not recommended.

“…The lower percent acidity the lower will be the pH and vice versa. These results were in correspondence with (Abd-Alla et al, 1996;Sainju et al, 2003;Kaminwar & Rajagopal, 1994) who said that at low phosphorus concentrations plant will produce fruits having high acidity.…”

“…These energy rich ATPs can also be transmitted to other coenzymes like uridine triphosphate (UTP) and guanosine (GTP), which are required for cellulose and sucrose synthesis (Marschner, 1995). These results were in correspondence with (Abd-Alla et al, 1996;Sainju & Singh, 2003) concluded that phosphorous enhances healthy root growth which helps in efficient utilization of water and nutrients resulting a strong stem and foliage growth, production of large number of flowers and early fruit setting. As a result, phosphorus enhances the number and production of tomato fruits.…”

“…They reported that seed yield depends upon the number of pods, seeds and average seed weight pod -1 (Ali & Iqbal, 2003;Wajid et al, 2010) reported that nitrogen increases vegetative growth so automatically reproductive stag is delayed while phosphorus enhances reproductive growth and the yield is high. According to (Abd-Alla et al, 1996;Sainju & Singh, 2003) phosphorous has a major role in enhancing early flowering, fruit set and maturity. It also increases number of fruits and production of fruits.…”

The study was designed to assess the effect of organic phosphorus on the growth, yield and post-harvest fruit traits of tomato. Plants were fertilized with five levels of fertilizers (containing 20% organic mineralized P2O5, 30% decomposed organic matter and 2% organic nitrogen) with the rate of 20, 40, 60, 80 and 100 kg ha-1 accompanied with a control. Results showed that Maximum survival percentage, No. of picking/plot, fruit weight, plant height, number of branches, maximum yield was also obtained from the plots treated with 60 kg ha-1 fertilizer. Plots with 60kg ha-1 of organic phosphorus required less days to produce 50% flowering and 50% fruit setting. Fruit maturity duration and No. of defective fruits were also minimum in the plots where fertilizer were applied with the rate of 60 kg ha-1. Results of post-harvest analysis of fruits also revealed that different levels of organic phosphorus (organic phosphorus as a source) have no significant effect on fruit firmness but with the increase in storage time firmness decreases significantly. Total soluble solids were also reduced with the increased level of fertilizer, with the increase in storage time increased the total soluble solids in fruit. Ascorbic acid was found with higher concentrations in high levels of fertilizer which was reduced significantly with the passage of storage time. Fruit juice had maximum pH value in the control treatment which was significantly reduced with the increase of fertilizer level. However, pH started to increase when fruit was stored for more than 12 days. From the results it can be concluded that fertilization with 60 kg ha-1 , tomato plant can response better during pre-harvest and post-harvest period.
