Abstract:
... Vegetable intercropping is an alternative to the conventional system and characterised by a greater efficiency of land use and inputs. For this reason, it is a more sustainable and low greenhouse gas emission (GHG) cultivation model. Thus, the objective is to estimate direct and indirect GHG emissions and the carbon footprint per kilogram of vegetables produced using the intercropping and monocult ...

Abstract:
... Soybean is an important legume crop that displays the classic shade avoidance syndrome (SAS), including exaggerated stem elongation, which leads to lodging and yield reduction under density farming conditions. Here, we compared the effects of two shade signals, low red light to far-red light ratio (R:FR) and low blue light (LBL), on soybean status and revealed that LBL predominantly induces excess ...
