Resumen:
Phosphytes are well-known compounds derived from
phosphorous acid and combined with
different cations, such as Potassium.
Phosphytes promotes, not only activation
of plant defense mechanisms plants but
also favor crop development. It was already reported that Potassium phosphyte (Kphi)
applied to seed tubers at 3 litre ha-1 promoted and earlier emergence and development of more
vigorous crops. The purpose of this work was to
assess the effect of Kphi applied to seed tubers on various physiological
variables during crop growth. A field
trial was carried out in a randomized block design with three replications of
potato processing cultivars Bannock Russet, Gem Russet and Shepody. Seed tubers
were treated with KPhi or water as control, immediately after seed cutting.
Kphi treated seed tubers promoted and earlier emergence, mainly in Bannock
Russet. Kphi treatments also increased stem number and stem diameter, advanced
tuber initiation and increase tuber number per plant. Also ground cover and
chlorphyll content were enhancing. Based on these results, it is concluded that
Kphi play an important physiological role by improving crop architecture and
yield components.
