Hi
1. Guar technically is Cluster bean, very hardy crop
2. You can grow this in huge areas during rainy season as rainfed crop
3. Being a leguminous crop, doesn't require much nutrients, rather improves the soil fertility by way of fixing atmospheric nitrogen
4. Treat seeds before sowing with bio-fertliser Rhizobium @ 100 gram per kg of seeds
5. Apply 75 kg Single Super Phosphate, 25 kg Ammonium sulphate and 25 kg Muriate of Potash before or at sowing
6. For more details contact me @
