Growth ,Yield And Fruit Quality Of Two Colored Sweet Pepper Hybrids As Affected By Different Sources of Nitrogen Fertilizers .

This research was carried out over two successive growing seasons (2022/2023and 2023/2024) at
the Experimental Greenhouse, Horticulture Department, Faculty of Agriculture, Minia University which
locates in Minia Governorate, Egypt (28.1243667 N, and 30.7289938 E). The study site was situated
within the middle Egypt region which has a semiarid climate with considerable temperature differences
between day and night. The experiment was conducted inside an ordinary unheated plastic greenhouse.
The experiment was laid out in a split-plot design with three replications throught CRBD: Two colored
sweet pepper hybrids (OLOM and KARMEN) were distributed in main plot and four nitrogen sources i.e.
urea, ammonium nitrate, and ammonium sulphate and bio-organic in sub plot.
The obtained results showed that both colored sweet pepper hybrids were differed each from other
on the growth parameters , yield and fruit quality depending on its genetical differences and its reaction
with environmental conditions, Also, the results indicated that hybrid OLOM was the best in most of the
measuremnt characters compared with KARMEN hybrid under the experimental conditions.
