Influences of irrigation interval,nitrogen fertilization and plant spacing on tomato fruit yield and quality

On-Line Sorting Maturity of Cherry Tomato Bymachine Vision

The cherry tomatoes online sorting according to their maturity is an important procedure after harvest. This research proposed an automated cherry tomato grading system base on machine vision. Three images of different angles are obtained from each cherry tomato, allowing the inspection of approximately 90% of the fruit surface. 9 features were extracted from the one cherry tomato images. In or...

Efficiency of nitrogen fertilization in spring wheat

An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...
