There are many problems encountered in grafted seedlings in the nursery. The time taken for bud growth in the nursery undergoes many conditions such water shortage , malnutrient , pest, diseases problems etc. Obvious symptoms where plants had dry stem and leaves fallen is due to lack of water. Durian seedlings is very sensitive to shortage of water. However, water uptake can be estimated by several methods. I calculate water consumption of plants by using 'actual evapotranspiration (aET)' technique.
Malnutrition is another common problem such Nitrogen (N) and Potassium (K) deficiency. These deficiencies are mainly due to mobile ions in plants.
