- Soil and water conservation measures to be adopted.
For proper growth and survival, it is necessary to give one or two waterings after planting. This is specifically required in arid regions. Irrigation after planting is not a prerequisite in areas having sufficient soil moisture and precipitation. Higher survival rate and better rate of growth is reported when soil and water conservation measures are also adopted.Recommended Harvest :
