The major product from Guar is Guar Gum which is a natural thickening agent used in edible products. One of the major export from India is Guar Gum, with some more research and development in the process and better technology, it will be highly profitable to the farmers.
Climate and Seasons
It is a Kharif crop. Guar is tolerant to high temperature, which is able to grow under hot conditions and optimum temperature to obtain maximum yield is 15 to 35ºC. Cluster Beans requires a optimal temperature of 25ºC for proper germination of seed, with requirement of short photoperiod and long photoperiod for its flowering phase. The crop is photo sensitive, drought and salinity tolerant. It can be grown both in arid and semi – arid condition and grows as rain fed crop requiring 300 -400mm rainfall in arid regions. The crop generally requires dry weather during maturity. Guar is drought tolerant, hence with limited moisture it stops growing but doesn’t die, although maturity is delayed. If there is excessive rainfall, the beans might be destroyed or come out as diseased. The crop prefers a humidity of 60 to 70%.
Cluster beans can grown in various types of soil but it is grown best in sandy loam soils with rainfall of 300 – 500mm. It is tolerant to soil salinity and alkalinity. For good yield , the soil pH should be neutral i.e around 7.0. Although it is salinity tolerant, but pod formation and yield might reduce due to increased salinity. Due to its leguminous nature, it is able to grow in poorly fertile soil due to its nitrogen fixing ability.

In order for the plant to get soil aeration and better root development, the lands needs to be ploughed 2 or 3 times, which is followed by planking. One needs to make sure that weeds are removed so that the plant is germinated well.
Seeds are required for propagation purpose.
Sowing, Nursery and Transplanting
Guar seeds are sown by broadcasting method which involves spreading of the seeds in the soil, followed by ploughing of the soil so that seeds are properly mixed with the soil. Sowing depends on rain which is usually done in Kharif season, with ideal time being 1st or 2nd week of July.
