Majajigua, Sancti Spiritus, Cuba (Cuban Ministry of Sugar) |
Variety: unknown Planting date: unknown Seeding rate: unknown Soil type: "gleyish" Vertisol |
Vitazyme application: 1 liter/ha during active tillering |
Comments: Despite the fact that the crop was not harvested, the Vitazyme treated crop was darker green 10 to 12 days after application, showing the product's effect to stimulate chlorophyll development. It was also noted that Vitazyme reduced plant stress during drought conditions.
