Hull Split NOW sprays
provide a great
opportunity to increase
this year’s nut size,
splits and yield and set
the stage for higher
yields next season.
However – many
conventional foliar
nutrient formulations
do not penetrate well, especially from mid-summer onward after the
pistachio leaf has hardened off and developed a thick waxy cuticle,
making them ineffective. But Agro-K’s Sysstem ® and Dextro-Lac ®
foliar product lines are designed to rapidly and completely move
through even the toughest, hardened off, waxy pistachio leaf – even in
late summer, making them extremely effective nutrient delivery tools.
Agro-K’s penetrating formulations allow growers to capitalize on the
freeride available with a summer Hull Split Navel Orange Worm spray to
apply the right nutrients, in right form, at the right time, in the right mix
and in the right place – the 5 R’s for foliar nutrition. Applying effective
nutrients based on a “Science Driven ” approach which can penetrate
leaf tissue will help maximize nut size and splits on this year’s crop,
increasing per acre returns. In addition, foliar nutrient programs added
to Hull Split NOW sprays will also increase next year’s crop. Even
though this year’s crop has not yet been harvested, by mid-season the
tree is already building next season’s crop. Take advantage of the free
ride to influence it!
In an August trial a mix of Agro-K nutrients, both micro and macro,
were applied to pistachio trees. Utilizing SAP testing methodology
over standard tissue testing allowed for analysis of “free nutrients”
only; meaning those nutrients currently mobile within the plant’s sap
and immediately available for plant use. Conventional tissue testing
measures what is already bound within the leaf structure and mostly
immobile. Measuring sap nutrient levels effectively detects recent
nutrient changes. The charts above show statistically significant
changes in six different nutrients 7 days after application. Zinc,
manganese, copper, molybdenum, potassium and phosphorus levels all
increased statistically vs. the control in the week after application.
This year, take advantage of your Hull Split NOW application to feed
your pistachio trees the key nutrients they need to maximize yield this
season and deliver higher yields next year.
