Abstract

Fertiliser has traditionally been applied to the soil, and plants obtained nutrients from the soil via their roots. Previous research has shown that foliar nutrition can work in tandem with soil fertilisation, or even replace it. This work looked at four liquid fertilisers: Albina containing calcium; Indra that promotes antioxidant production and contains nutrients to enable their production; Lono K containing nitrogen and potassium; and Lono Plus containing nitrogen and calcium (all products Levity Crop Science, UK).

Albina and Indra were applied at 0.5, 0.75, 1 and 1.25 l/ha for three applications; Lono K and Lono Plus were applied at 1, 1.5, 2 and 2.5 l/ha for five applications. Stem length and diameter; number of stems and flowers; weight of stems; shelf life; and cost benefit were recorded and calculated.

All products at all application rates gave significant improvements over the grower standard edaphic fertilisation (EF) program. Considering the return on investment of applying the products, the 1 l/ha Albina, 0.75 l/ha Indra and 1.5 l/ha Lono K and Lono Plus application rates were the best.
