Era Boost Pro – Field-grown lettuce

Results of trials on the growth and yield of field-grown lettuce.

In addition to measuring the effect of Era Boost Pro on yield, this trial aimed to evaluate different strategies for applying the product. Frequency of application, product concentration and time of application were evaluated.

In contrast to many other trials, here the lettuce plants, though field-grown, were grown under mulch and irrigated to minimize the effects of environmental stress.

Among all the tested application techniques, the best results were observed when the crop received two applications. The first application was on seedlings in seed flats after germination and root system development (required in this case because the bacteria present in Era Boost Pro are rhizospheric bacteria).


The second application was made one month after transplanting in the field.

Applying the product on seedlings in the greenhouse is a very low-cost technique and easy to operationalize. This combination of applications increased the yield of lettuce by 23.4%.
