GUAR CULTIVATION IN RAJASTHAN


Guar means "cow food" in Hindi. For best growth, the guar bean requires full sunshine, flashing rainfalls that are moderately frequent, and well-drained soil. However, it is extremely drought-tolerant and thrives in semiarid regions. Too much precipitation can cause the plant to become more "leafy", thereby reducing the number of pods and/or the number of seeds per pod that affects the size and yield of seeds. The crop is sown after the first rains in July and harvested in late October. It is grown principally in northwestern India and Pakistan with smaller crops grown in the semiarid areas of the high plains of Texas in the USA, Australia and Africa. The most important growing area centres on Jodhpur in Rajasthan, India where demand for guar for fracking produced an agricultural boom as of 2012.

Currently, India is the main producers of clusterbean accounting 80% production of the total world, whereas Rajasthan occupies the largest area (82.1%) under guar clutivation in the country. In addition to its cultivation in India, the crop is also grown as cash crop in other parts of the world (Pathak et al 2010). India is the source of about 80% of the world production of guar gum. Several commercial growers have converted their crops to guar production to support the increasing demand for guar and other organic crops in the United States.

Guar seed is grown in the northwestern parts of country encompassing states of Rajasthan 
(Churu, Nagaur, Banner, Sikar, Jodhpur, Ganganagar, Sirohi, Dausa, Bikaner, Hanumangarh 
and Jhunjhunu), Gujarat (Kutch, Banaskantha, parts of Mehsana, Sabarkantha, Vadodara 
and Ahmedabad), Harayana (Bhiwani, Gurgaon, Mahendragrh and Rewari) and Punjab 
(Bhatinda, Ferozpur, Muktsar and Mansa). 
Rajasthan is the largest growing state of Guar seed in the country accounting for 70% of 
total production. The other producers are Gujarat, Haryana, Punjab, Uttar Pradesh and 
Madhya Pradesh.

GUAR GUM


Guar Gum is an important ingredient in producing food emulsifier, food additive, food thickener and other guargum products. India is the largest producer of guar gum products. Its guar gum exporters, guar gum manufacturers, guar gum products suppliers, foo emulsifier exporter have reached to many countries and today there is a lot of demand for indian guar gum products, food additives, food thickener and other allied guar gum products.

Guar gum is extracted from the seed of Cyamopsis tetragonoloba, an annual leguminous plant originating from India and Pakistan, also cultivated in the United States. Guar Gum grows best in sandy soils, in areas of West, Northwest India and parts of Pakistan, which are ideal for it's farming. Jodhpur City in the North Western state of Rajasthan in India is the most important processing center of Guar Gum and contributes approximately 40% of the world's Guar Gum supply. Indian Guar Gum Products are exported and supplied all over the world by different guar gum exporters, guar gum manufacturers, guar gum suppliers and guar gum exporter. Many food emulsifier exporter also exports superior quality food additive, food thickener and food emulsifier.

Guar gum is an emulsifier, thickener, and stabilizer approved for use in a wide range of foods, cosmetics, and pharmaceuticals. Gum Technology Stabilizers are carefully controlled blends of various food ingredients. They are mostly natural vegetable gums which come from sources such as seeds, plant exudate and marine plants. These may be blended with other hydro-colloids or food ingredients such as fats or emulsifiers.



Industrial application of guar gum includes the textile industry where guar gum's excellent thickening properties are used for textile sizing, finishing and printing. In the paper industry Guar is used as an additive where It gives denser surface to the paper used in printing. And in the explosive industry guar is mixed in Ammonium Nitrate, Nitroglycerine and Oil explosives, where it helps maintain the explosive properties of the product even in wet conditions.

In the food, pharmaceutical and cosmetics industry, Guar Gum is used as an effective binder, stabilizer, dis-integrator and thickener. In bakeries, diaries and in production of meat and, dressings and sauces, Guar is an important natural food supplement with high nutritional value, for weight gain and cholesterol reduction. In cosmetics, especially shampoos and toothpastes, guar gum is used primarily as a thickening and suspending agent. In beverages, it is used as stabilizer for preparing chocolate drinks and juices.

GUAR GUM CULTIVATION IN INDIA


India is native of guar or cluster bean where it is used as a vegetable. From hundreds of years Guar has been used as vegetable in India. It is also used as a cattle food, and as a green manure crop in agriculture. Guar gum comes from the endosperm of the seed of the legume plant Cyamopsis tetragonoloba; an annual plant, grown in dry regions of India as a food crop for animals. There are various grades of Guar gums pure or derivative. Guar gum is a white to creamy coloured, free flowing powder and free from extraneous matter. Its ability to suspend solids, bind water by hydrogen bonding, control the viscosity of aqueous solutions, form strong tough films have accounted for its rapid growth and use in various industries. For example guar gum is used in paper, textile, oil drilling, mining, explosives, ore flotation and other various industrial applications.
The growing season of guar is 14 -16 weeks and requires reasonably warm weather and moderate flashing rainfall with plenty of sunshine. Too much rain can cause the plant to become more 'leafy' resulting thereby reducing the number of pods or the number of seeds per pod which affects the size and yield of seeds. The . the total size of Guar crop varies from year to year. After harvesting, when the pods become dry through sunlight, they are beaten off and during this process, the seeds come out of the pods.
