Biological inputs lift sugar beet yields as UK growers adapt to new pressures

As UK sugar beet farmers face mounting challenges from unpredictable weather, tighter regulatory frameworks, and escalating disease pressure, biological crop inputs are emerging as a commercially viable part of the modern crop management toolkit.

Recent independent trial work by Richard Austin Agriculture, supported by Unium Bioscience, has shown that products such as T6P and Klorofill can deliver a significant uplift in yields and crop quality. In trial plots, yields increased by over 13%, with untreated crops averaging 75.52 tonnes per hectare compared to 85.5 T/ha in plots treated with T6P. Klorofill delivered similarly strong results at 84.66 T/ha.

Beyond raw yield, the treatments also improved sugar concentration—particularly T6P, which raised sugar levels above 17%. Lower amino nitrogen levels under Klorofill treatment further indicate improved processing efficiency and product quality.

Mark Hemmant, Technical Manager at Agrovista, the exclusive distributor of both products, said the results validate field observations over the past seasons. “These biologicals help crops maintain health and performance under pressure, which translates directly into returns for growers.”

According to Unium Bioscience commercial manager Andrew Cromie, crop observations throughout the growing season aligned with the biologicals’ known modes of action. A first application in June supported chlorophyll development at a key stage for photosynthesis, while a second in September aided sugar translocation to the root. “The improvements are measurable,” Cromie said. “We’re seeing healthier plants, improved photosynthesis, and more efficient carbohydrate distribution—especially under stress.”

Klorofill, in particular, appears to help manage oxidative stress by reducing haem accumulation in sugar beet plants, thereby supporting leaf function during adverse conditions. T6P enhances sugar movement toward the taproot, contributing to both root mass and sucrose levels.

“These trials reinforce that biologicals are not only environmentally sound but also economically effective,” Cromie added. “They build resilience into the crop and reduce the need for synthetic inputs.”

With growing interest in sustainability and yield efficiency, the results are likely to attract further attention from growers ahead of the next planting season. For many, the integration of biologicals may offer a practical pathway to meet both regulatory and productivity goals.
