Shohruh Zafar o'g'li Abdullayev first of all, hydro-gel is a material that can retain much amount of water compared to its volume and also for a longer period of time. In non-irrigated /dry-lands/rain-fed areas the main constrains is water availability, where water is either deficient or available for a certain period of time. so there we could expect a bumper production if the period of water availability is increased or if it could be supplied during critical stages of growth. In this context Hydro-gel may act as a boon as it can hold a much amount of water in it and supply it uniformly throughout the entire growth period. As the crop doesn't encounter any kind of water stress so we could expect a good harvest.
besides the yield increase as it helps in maintaining a good soil moisture regime so there a good soil microbiological activity that will definitely adds to a better soil biological processes.
