The goal of this study was to examine how improve the vegetative growth, nutritional status, productivity, and fruit quality Washington navel orange trees by examining effect foliar application ZnSO4 (0, 300, 600 mg/L) solutions in combination with CuSO4 200, 400 on trees, which were 11 years old grown clay loam soil a surface irrigation system. results showed that all investigated measurements...

Laser induced breakdown spectroscopy (LIBS) has become a powerful tool for the direct analysis of a large variety of materials in order to provide qualitative and/or quantitative information. However, there is a lack of information for LIBS analysis of agricultural products. In this work a LIBS system has been designed for the discrimination of Ca, Cu, Fe, and Na elements in Gannan Navel orange...

Concentrations of the macronutrients (K, Ca, Mg, Na, P and S) and micronutrients (Fe, B, Zn, Mn and Cu) in whole fruit, pulp, rind and albedo of fruit from young and mature 'Bellamy' navel orange trees were measured at fortnightly intervals during fruit development. The general order of abundance of the macronutrients were K > Ca > Mg ˆ P > S > Na and the abundance of the micronutrients followe...

6 Common techniques to monitor the quality of fruit at the time of harvest and in storage typically rely on destructive methods to measure physical properties such as firmness and hydration. The complex, inhomogeneous composition of most fruit mean that non-destructive ultrasonic methods for quality evaluation of fruit has typically been unsuccessful. A novel ultrasound method was developed whi...
