Science Driven Nutrition Delivers
Increased Yields in Almonds
and Pistachios This Year and Next
Finishing this year's crop relies on well-timed nutrient
applications that satisfy the demands of hard-working trees.
Applying effective nutrients based on a " Science Driven "
approach will maximize nut size and splits on this year's crop,
increasing per acre returns.
In almonds and pistachios, next season's crop starts developing
now as vegetative tissue in the newly grown wood. To develop
into flowers, and ultimately nuts, these tissues undergo a series of
changes: floral induction, initiation, determination, and
differentiation. These changes are heavily influenced by mineral
nutrient and carbohydrate levels in the plant. To complicate
matters, many of these processes overlap and are competing
against the developing fruit for nutrients and carbohydrates.
To ensure that both this and next years' crops are a success, the
nutritional needs of the flower buds need to be addressed while
they are developing. Nutrient deficiencies during flower
development have irreversible consequences which lead to
reduced flower numbers, flowers with immature sex organs,
delayed and sporadic flowering, premature flower abscission,
decreased pollen count, and pollen viability. Zinc, manganese,
copper, molybdenum, and boron are all needed for the
development of healthy, viable flowers.
Applying the Right nutrients, in the Right form, at the Right time,
in the Right mix and in the Right place-Agro-K's 5 Rs of Plant
Nutrition-maximizes nutrient uptake, availability, and synergy
while minimizing nutrient antagonisms and wasted dollars.
In Pistachios, floral bud development begins as early as April,
continues throughout May and June, and then rests until October,
when differentiation resumes.
In almonds, floral bud development begins from roughly 2 weeks
prior to hull split up to a few weeks after, depending on the variety.
Female flower parts determine and differentiate first, while male
flower parts develop in late dormancy (generally December
through bloom).
Foliar nutrient applications at Hull Split in almonds and kernel
bulking to hull slip timings in pistachios provide the best
opportunities to nutritionally impact flower development for next
year's crop while reducing abiotic stress issues this year. Agro-K
nutritional tools applied at hull split help support and finish off this
year's crop, reduce stress factors, and begin to store key nutrients
needed to support a strong bloom and nut set next season.
Seabest 0-19-19 supports nut fill with potassium, reduces heat and
other stressors with potassium and seaweed, and supplies
phosphorus to help build carbohydrate reserves for next year's crop.
Sysstem-LeafMax is a one jug solution that contains all the
nutritional components needed to maintain chlorophyll levels and
activity in a formulation that easily penetrates thick waxy leaf cuticles.
Applying Seabest 0-19-19 and Sysstem-Leafmax at hull split in
almonds and bulking to hull slip in pistachios is a win-win for your
trees and your bottom line. Beginning to manage next year's
nutrient needs now will improve nut set, reduce nut drop, and will
increase both nut size and total yield. Don't miss the yield boosting
opportunity hull split sprays offer!
