Trial results in other crops
In Queensland’s Lockyer Valley, a trial in organic potatoes involved using Utrisha N in conjunction with a standard organic fertiliser program of organic soil ameliorants. Utrisha N is certified by OMRI and Australian Certified Organic for use in organic crop production. Potato yield increased by 8.3% compared to the standard organic fertiliser program, with more uniform tuber set and sizing, increasing marketable yield. This potentially helps processing efficiency due to the consistency of potato size.
The strong results were also reported from an onion trial site in the Lockyer Valley. Utrisha N was applied at the four-to-six leaf stage in conjunction with a standard fertiliser program of Preplant NPK blend, followed by in-crop soluble potassium nitrate and micronutrient program. Brown onion yield increased by 22.5% and red onion by 10%, compared to onions subject to the standard fertiliser program.
At Stanthorpe, a grower trial in Wombok returned an increase yield of 9% compared to a standard fertiliser program when 333g/ha of Utrisha N was applied at the four-leaf stage and in conjunction with a standard fertiliser program.
Corteva Agriscience Plant Health Manager, Dan Cornally, said with grower trials completed in many other horticulture and broadacre crops, including grapes, strawberries, wheat, canola and lentils, Utrisha N offered a new nitrogen management strategy for growers.
