Abstract:
Evaluating fertilizer quality is important in selec
ting the appropriate fertilizers for
agricultural production. In this experiment, the ef
fectiveness of Composite Inorganic
Fertilizer (CIF), Composite Organic Fertilizer (COF
) and Foliar Spray of Multi-Nutrients
(FSMN) on the growth, yield, and fruit quality of c
herry tomato (
Lycopersicon
esculentum
Mill.) were compared. The results showed that the a
pplications of fertilizers enhanced the
leaf area, photosynthesis rate, fruit setting rate,
and average fruit weight, and yield. The
fruit setting rate and average yield in COF treatme
nt increased by, respectively, 25.16%
and 81.91% when compared to the control (without fe
rtilization). Also, the contents of
reducing saccharide, vitamin C, and lycopene in tom
ato fruit improved, especially in the
COF treatment, in which the contents of saccharide,
vitamin C, and lycopene were higher
than the control by 40.84%
, 28.74% and 13.97%. Treatment CIF had similar effe
cts on
growth and yield when compared to COF, but the infl
uence of CIF on the fruit quality
was lower than that of COF. Meanwhile, treatment CI
F also had the highest contents of
nitrate and nitrite in the fruit (2.32 and 1.42 mg
kg
-1
, respectively). In this study, FSMN
was ineffective when used separately.
