"Kakaiba ang bulas at quality ng aking vegetables mapa-greenhouse man or open field gamit ang smart release foliar fertlizers na Seedling Booster, Nitroboost at Completo+ ng GameChanger Agriculture Corporation...kasama na sa aking production system and GameChanger protocols para malaki ang ani at maganda ang quality ng harvest!!!"

  • Tissue analysis at harvest revealed that a summer cabbage crop uses about 36.3KG/HA of Nitrogen, divided fairly equally between the head and the leaf and stump residue

  • Studies showed that Nitrogen uptake by the cabbage crop exceeded the amount of Nitrogen applied via fertilizers

  • In the 2016 trial, Nitrogen uptake exceeded amount applied (150 lb/A) by 35 to 73 lb/A (=23 to 48%)

  • Cabbage crop is a very efficient nutrient scavenger

Researcher's Conclusions

  • NITROBOOST at 6li/ha application applied 3x provided the highest yield with 49 tons/HA equivalent to 63% increase or 19 tons/HA higher than farmer's practice (T1 - RRGF) and better than the commonly used foliar fertilizer especially Brand E and Brand C

  • COMPLETO+ at 4li/HA applied 3x produced a yield of 44.67 tons/HA far better than the popular foliar fertilizers (Brands C, H, CG & G)

  • Application of half the rate of granular fertilizer plus application of COMPLETO+ at the rate of 4 li/ha applied 3x provided a 20% yield increase, indicative that the reduction is well compensated with the application of COMPLETO+

  • The same result was observed with NITROBOOST applied at 5 li/ha and half the rate of granular fertilizers

What is the optimal NITROGEN level for CABBAGE?

For superior growth and maximum yield using NITROBOOST & COMPLETO+, aim for a SPAD Meter reading between 74 and 155, indicating a healthy range of 3.50% - 6% nitrogen.
