Challenges of devising nitrogen recommendation systems for open field vegetables
Large amounts of nitrogen fertiliser are often applied to field vegetable crops to ensure the maximum yield of quality produce. To avoid unnecessary environmental pollution the amounts of nitrogen could easily be optimised. However the process of devising nitrogen recommendation systems can be complex, as crops are so diverse and can be grown in intensive and varied rotations. Further information
Preceding crop and seasonal effects influence fungal, bacterial and nematode diversity in wheat and oilseed rape rhizosphere and soil
Crop rotation can have major influences on yield, which may be the result of changes in the composition of the rhizosphere microbiome In the current study we investigated the effect of preceding crops on wheat and oilseed rape yield, with associated changes in the rhizosphere and bulk soil communities of fungi, bacteria and nematodes using terminal restriction fragment length polymorphism (TRFLP) of rRNA genes. We conclude that overall, preceding crop had less impact on community composition than season or crop type, but that specific changes in communities at particular plant growth stages may have substantive impacts on crop growth.
The use of an electronic nose to detect early signs of soft-rot infection in potatoes
Massimo F Rutolo, John P Clarkson, James A Covington
In this paper we report on the detection of soft-rot in potatoes caused by the bacterium Pectobacterium carotovorum through the use of an array of low cost gas sensors. This disease results in significant crop losses in store (circa 5%) with associated negative financial impacts. As soft-rot is associated with a strong odour and there is forced air movement through potato stores, our aim was to investigate the potential of an array of low-cost gas sensors to detect the disease. The identified sensors offer promise for an automated in-store monitoring system
Inoculum potential of Sclerotinia sclerotiorum sclerotia depends on isolate and host plant
The soilborne fungus Sclerotinia sclerotiorum infects many important crop plants. Central to the success of this pathogen is the production of sclerotia, which enables survival in soil and constitutes the primary inoculum. This study aimed to determine how crop plant type and S. sclerotiorum isolate impact sclerotial production and germination and hence inoculum potential. These findings, once further validated in field trials, could be used to inform future crop rotation decisions.
Handbook of Pest Management in Organic Farming - Pest Management in Organic Field vegetables in Temperate Areas
Daniel, Claudia; Collier, Rosemary; Niggli, Urs and Koller, Martin (2018) Pest Management in Organic Field vegeatables in Temperate Areas In: Vacante, Vincenzo and Kreiter, Serge (Eds.)
Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production.
A laboratory simulation of Arabidopsis seed dormancy cycling provides new insight into its regulation by clock genes and the dormancy‐related genes DOG1, MFT, CIPK23 and PHYA
Footitt, S., Ölcer‐Footitt, H., Hambidge, A. J., Finch‐Savage, W. E
Environmental signals drive seed dormancy cycling in the soil to synchronise germination with the optimal time of year; a process essential for species fitness and survival. Previous correlation of transcription profiles in exhumed seeds with annual environmental signals revealed the coordination of dormancy regulating mechanisms with the soil environment. Here, we developed a rapid and robust laboratory dormancy cycling simulation using mutants in known dormancy-related genes. Involvement of the clock in dormancy cycling was clear when mutants in the morning and evening loops of the clock were compared. Dormancy induction was faster when the morning loop was compromised and delayed when the evening loop was compromised.
