Abstract:
... The objective of our analysis was to demonstrate a novel application of production risk (probability of a yield falling below a certain level) and yield stability analysis based on the totalized yield across a `sugar beet–winter wheat–spring barley´ crop rotation. We evaluated a long-term experiment spanning more than 60 years regarding the effect of mineral NPK fertilization and the additional su ...

Abstract:
... To improve the quality of fertiliser centrifugal spreading, several control devices have already been developed to manage some disruptions occurring on horizontal fields. However, controls which manage disruptions on non-flat fields due to changes in tractor attitude (pitch and roll) have not been developed. In this study, the design of a new control device is developed for a twin-disk spreader by ...

Abstract:
... Spring-summer production of lettuce under greenhouses is highly affected by Tipburn development, a physiological disorder attributed to localized calcium (Ca) deficiency. As Ca is distributed along the plant tissues together with the water flux, Tipburn development is related to environmental conditions. Until now, no growing condition that avoids this disorder, without an associated yield penalty ...
