Re­search for the 2017/18 sea­son is well un­der­way with tri­als planted and re­search pro­grammes half way through their in­ves­ti­ga­tion. Re­search is be­ing un­der­taken with both pro­cess­ing and seed crops and in Can­ter­bury, Manawatu and the wider Pukekohe re­gion.

Progress with the main re­search ar­eas for the up­com­ing sea­son is as fol­lows:

In­creas­ing potato yield through un­der­stand­ing the im­pact of crop ro­ta­tion and soil com­paction (Sus­tain­able Farm­ing Fund­ing, FAR project P15-01)

• This year will be the third and fi­nal year of the project.

• One as­pect not ad­dressed in Years 1 and 2 was the ef­fect of pre-plant (potato) cul­ti­va­tion on the soil qual­ity. By the time th­ese ques­tions were posed, cul­ti­va­tion work for spring 2017 potato crops was well un­der­way, and some early passes (in­clud­ing those in au­tumn 2017) al­ready com­pleted, there­fore the time­line needed to un­der­take this re­search would not fit into the third year of this SFF project. It was de­cided to save this work for a fu­ture project and in­stead con­tinue to pur­sue the seed health is­sue, which left some unan­swered ques­tions from Year 2.

Hot and cold psyl­lids (FAR project P17-04)

• The aim of the in­ves­ti­ga­tion is to pro­vide data on TPP
