In a trial that was conducted in Tongjiang, China,
Haifa china agronomists examined the advantages of using drones to apply Poly-Feed™ Stim Armor on a rice crop, In comparison with the foliar application of MKP (the farmer actual practice).
After 3 rounds of foliar application, the results amazed all: Grain yield increased by 14% which resulted in a big revenue.
► Increased grain yield
►Increased grain weight
►Increased net income
►The stalk is stronger than framer practice, more resistance to lodging
Trial objective: Evaluate the benefits of HaifaStim™ Armor applied via drones on rice crop.
Location: Tongjiang,Jiamusi, China.
Application dates:
► 1st foliar on June 15th, 2021
► 2nd foliar on July 13th, 2021
► 3rd foliar on Aug 3rd, 2021

Notes:
1.local growers also don’t use any plant nutrition for foliar at early . They prefer 15-15-15 30Kg/mu for base dressing, 30-0-5 10 Kg/mu for side dressing
2.In Jiamusi area, 100% drone for foliar, no famers use conventional back sprayer at all.

Also by applying Poly-feed™ stim ARMOR, the stalk is more resistant to lodging than framer technique.
Poly-Feed™ Stim ARMOR combines the nutritional values of Poly-Feed™ foliar with the benefits of silicon.
The silicon added to Poly-Feed™ Stim ARMOR is in the form of fully soluble stabilized silicic acid, which ensures availability for plant uptake, and high efficiency.
The silicon benefits for the plant are:
♦ Improves overall health
♦ Better uptake of nutrients (K,P and Ca)
♦ Lessen drought stress
♦ prevent excessive uptake of N and P
♦ Eases toxicity of Mn, Cd, As, Al, and Zn.
