Shawer, S.S. and I.M. Abdalla( 2019). Effect of organic and nano nitrogen fertilization on soil properties, crop production and nutrients uptake by corn plant in sandy soilsJ.Biol. Chem. Environ. Sci., 2019, Vol. 14(1): 247-262
Abstract: 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, 30, 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.
