Chaudhary Charan Singh Haryana Agricultural University has developed a new mustard variety RH 0749 which has been identified for cultivation under timely sown, irrigated conditions in zone II comprising Haryana, Punjab, Jammu, Delhi and northern Rajasthan. Dr R P Narwal, director of research, said the yield from this variety was 15 per cent more than the existing high yielding varieties. This variety gave an average yield of 26-28 quintals per hectare in about 150 days. Its seeds were bold and had 39-40 per cent oil content. Dr Dhiraj Singh, head of the oilseed section, said weed experts of the university had devised a technique for the management of orobanche parasitic weed. The validation of this technology would enhance the crop productivity and production of rapeseed and mustard.
