Potassium nitrate provides many positive effects on crops that lead to improvements in the quality of the yields:
- Improves plant resistance to biotic and abiotic stress
- Higher protein content
- Higher starch content in grains and tubers
- Higher vitamin C content
- Better colour and taste of the fruit
- Larger fruit size
- Thicker fruit skin
- Less physiological damage (wrinkling of the fruits’ skin and cracking of citrus fruits, ripening spots on tomatoes, etc.)
- Better quality during storage and transportation
- Longer shelf life
