Monitoring Nitrogen Status of Organically-grown Strawberry Cultivars by Using Chlorophyll Meter Reading

Monitoring of Cultivars Identity and Genetic Stability in Strawberry Varieties Grown in Egypt

A simple and routine method for the analysis of tissue culture-derived strawberry plants for somaclonal variations is a prerquist for pricise monitring of quality control during rapid mass micropropgation. Similarly, molecular identification of different varieties is an important element for efficient and effective management of strawberry genetic resources. This study reports on the use of RAP...

Nitrogen isotope composition of organically and conventionally grown crops.

Authentic samples of commercially produced organic and conventionally grown tomatoes, lettuces, and carrots were collected and analyzed for their delta15N composition in order to assemble datasets to establish if there are any systematic differences in nitrogen isotope composition due to the method of production. The tomato and lettuce datasets suggest that the different types of fertilizer com...

Simple Assessment of Nitrogen Nutrition Index in Summer Maize by Using Chlorophyll Meter Readings

Rapid and non-destructive diagnostic tools to accurately assess crop nitrogen nutrition index (NNI) are imperative for improving crop nitrogen (N) diagnosis and sustaining crop production. This study was aimed to develop the relationships among NNI, leaf N gradient, chlorophyll meter (CM) readings gradient, and positional differences chlorophyll meter index [PDCMI, the ratio of CM readings betw...
