ABSTRACT
Two field experiments were carried out during 2017/2018 and
2018/2019 seasons at Al –Hussein Society of Reclaiming and Cultivating
Land, 64 km Cairo Alexandria desert road, Giza Governorate, Egypt, to
study the effect of nitrogen with nano metric fertilizer rates and some micro
elements on Productivity and quality of canola c.v. Serw4. The experimental
design used was a split plot design with three replications. Each replicate
included 20 concentrates which were the combinations between five
nitrogen fertilizer rates, i.e., 10 kg N (mineral) +20% from recommended
nitrogen as nano. N / fed., 20 kg (mineral) +20% nano, 30 kg N +20% nano,
40 kg N (mineral) +20% nano. N, 50 kg N(mineral) +20% nano. N. were
allocated in the main plots, and four micro elements rates used as nano
metric fertilizers, Control (sprayed plants with recommended of Iron+
manganese), spraying plants with Fe + Mn at concentrations 100, 200, and
300 ppm concentrates, while micro elements were distributed randomly in
the sub plots. while 50kgN+20% nano/fed rate gave the maxmum for plant
height and number of branches/plant in the two seasons.
The obtained results showed that nitrogen fertilizer rates significantly
affected yield of canola and growth characters in both seasons. Application
nitrogen fertilizer with rate (40 kg N +20% nano. N/ fed) gave the highest
seed yield and 1000seed weight. The obtained results indicated that spraying
canola plants with Fe + Mn at concentrations 300 ppm increased yield and
growth characters in both seasons as compared with the control. However,
the obtained results indicate that to obtain higher characters for canola, it is
recommended that application nitrogen fertilizer with rate 40 kg N +20%
nano. N/ fed and applying spraying plants with Fe + Mn at concentrations
300 ppm under drip-irrigated and experiment soil condition.
