The area under guar is expected to rise by 28 per cent to 450,000 hectares in the coming kharif season, according to experts. The country had planted guar in about 350,000 hectares in the last kharif (summer) season. According to market analysts, the prices of guar are expected to remain in the range of Rs 28,000-30,000 per quintal as there is almost negligible stock left due to high demand, which will also encourage the farmers to sow the commodity again in a larger area.
