Abstract:
In India more than 68 % area is under dry land condition and more than 40 % of the area faces the problem of insufficient rainfall. To overcome this problem, Hydrogel may prove as a convenient and eco-friendly feasible option to achieve the goal of crop productivity under conditions of water scarcity. Hydrogels are cross-linked polymers with a hydrophilic group which have the capacity to absorb large quantities of water without dissolving in water. It is commonly known as plant gel or super absorbent polymers which can absorb 400-1500 times water by its dry weight. When its surroundings begin to dry out, the hydrogel gradually releases up to 95 % of its stored water. As it is hydrophilic in nature, it has good swelling capacity, lack of toxicity and controlled water released thus, it has an immense scope to grow ornamental plants. It plays an important role in conserving water, reducing irrigation frequency and release sufficient moisture to grow roots of ornamental plants. It improves plant growth and density, increase flowering and dense foliage. Moreover, it helps to plant withstand prolonged moisture stress as well as delays onset of permanent wilting point. Hydrogels also improve the physical soil properties like soil porosity, soil permeability and water infiltration which will significantly reduce surface runoff and soil erosion.
