Abstract:
... A critical factor in the in vitro propagation protocols of sugarcane is the survival and plants growth under ex vitro conditions. The objective of this research was to determine the effect of VIUSID Agro® and FitoMas-E® during the ex vitro acclimatization of sugarcane, cultivar C90-469 under conditions of a shade house. Three concentrations (0, 0.5 and 0.8 mL L⁻¹) of both biostimulants were evalua ...

Abstract:
... Continuous cropping of soybean often causes significant declines in yields of soybean because of the outbreaks of soil-borne fungal diseases. It has been reported that wild crops often harbour a unique microbiome to benefit the host plants. Thus, it is necessary to find the different community structures of the rhizomicrobiomes associated with cultivated and wild soybeans in their continuous cropp ...

Measuring the effect of LC on agricultural production (ELCAP) is helpful for the planning of LC activities. In the past, it is difficult to measure ELCAP at regional level due to the lack of field observation, the change of crop planting structure, and high cost of sample collection. Satellite data have large ...
