EFFECT OF ORGANIC AND NANO NITROGEN FERTILIZATION ON SOIL PROPERTIES, CROP PRODUCTION AND NUTRIENTS UPTAKE BY CORN PLANT IN SANDY SOILS

A field experiment carried out at the experimental area of the El-
smallia station search, Egypt, during summer season of 2018 of three
compost fertilization rates (0, 10 and 20 ton/fed) were added before
planting. Meanwhile, nano- nitrogen fertilizers added levels (0, 3, 45
and 60 kg N /fed) as well as 100 kg N/fed mineral nitrogen
fertilizers; on grain yield (kg/plot), ear weight (kg/plot), grain yield
(kg/fed), length (cm), grain yield (Ardab /fed) of plant either nutrients
content and uptake by corn plant (zea mays L.) grown in sandy soil.
The obtained results showed that application of the compost
fertilization rates and nano- nitrogen fertilizers added levels added
alone or in combination with each other led to significantly increase
grain yield (kg/plot), ear weight (kg/plot), grain yield (kg/fed), length
(cm), grain yield (Ardab /fed) of plant. In addition, the phosphorus,
and potassium concentration (%) and uptake (kg/fed) by grain in corn
plant, significantly increase with increasing compost rates a combined
with nano nitrogen fertilizers, the highest values was recorded the
treatments of 20 ton/fed with100 kg N/fed. It was noticed that, the
highest values of N-uptake (kg/fed) at 20 ton compost with 60 kg
nitrogen level. This may be attributed to the positive effects of
compost manure and nano nitrogen fertilizers on available nutrient in
soil have demonstrated the importance of optimum mineral supply,

independent of nutrition. On the other hand, addition of compost
fertilization rates to soil in combination with nano- nitrogen fertilizers
caused a high increase of the available nitrogen, phosphorus and
potassium due to increase of soil fertility compared with control
treatment as well as improve soil properties. Generally, from these
results it can be concluded that the application compost fertilization
rates and nano- nitrogen fertilizers level improved all growth
component, some nutrients concentration (%) and uptake in grain of
corn plant.
