Abstract:
... Increase in machinery size and its random traffic at fields cause soil compaction resulting in damage of soil structure and degradation of soil functions. Nowadays, rapid methods to detect soil compaction at fields are of high interest, especially proximal sensing methods such as electrical conductivity measurements. The aim of this work was to investigate whether electromagnetic induction (EMI) c ...

Abstract:
... Large scale germplasm screening for Chilo partellus resistance in maize is solely based on visual scoring of damage by leaf injury rating (LIR), where the accuracy in judging a genotype comes by experience of the person, who logically integrate certain symptoms such as levels of growth retardation. Since the pest spends more than half of its larval period damaging the stalk, a quantitative phenoty ...
