Response of cluster bean (Cyamopsis tetragonoloba L. Taub.) to organics and fertilizers in hyper arid region: A review

Akshika Bhawariya* and Gayathri

Cluster bean (Cyamopsis tetragonoloba L.Taub.), also known as guar, is a coarse, drought-tolerant legume that is primarily grown during the kharif season in arid and semi-arid regions of the country. Important minerals such as calcium, phosphorus and iron are generally lacking in cereals but abundant in this legume. The natural polysaccharide water-soluble polymer found in endosperm, known as galactomannan gum, is the primary product used in many industries. Cluster bean cultivars with a high gum content (>32%) are more suitable for export. Panchagavya and Jeevamrut are affordable, eco-friendly organic concoctions crafted from cow by-products such as dung, urine, milk, curd and ghee. Panchagavya is an effective plant growth stimulant and organic product that can help promote growth and provide immunity in the plant system. Panchagavya contains growth regulatory substances such as Indole-3-Acetic Acid (IAA) and Gibberellic Acid (GA), which are required for crop growth. Jeevamrut stimulates significant biological activity in the soil, making nutrients available to crops. Cow urine has anti-fungal properties and is a good source of plant nutrients. Cow manure is high in minerals, specifically nitrogen, phosphorus and potassium. When mixed with soil, it promotes the growth of beneficial microorganisms.
