Advantages of use

Urea: Urea is the biggest source of nitrogen supply in the crop. By its use, there is no problem with the yellowing and drying of leaves. Urea accelerates the process of photosynthesis.

Zinc: Zinc helps in carbohydrate, protein and chlorophyll formation in okra plants. Which is responsible for driving metabolic reactions. This increases the production as well as the quality of the crop. In addition to zinc, it also makes sulfur available to crops. And sulfur helps in fruit formation in okra. Also, sulfur helps in protein formation.

Calbor: Calbor contains Calcium + Boron which is essential for nutrition, growth, photosynthesis, transport of sugars and cell wall formation.
