Response of sorghum [Sorghum tricolor (L.) Moench] cultivars to weed management

A field experiment was undertaken at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan). Response of sorghum [Sorghum bicolor (L.) Moench] cultivars to weed management was found out during kharif 2010. Results showed that the weed free treatment gave significantly higher earhead weight, grain weight/earhead, weight of 1000 grains and grain, stover and biological yields and net returns. While the B: C ratio was highest under intercropping with cowpea+1 HW. The corresponding increases in grain, stover and biological yield due to weed free were of the order of 103.46, 23.77 and 38.37% over weedy check. Among cultivars, CSH 16 gave higher grain yield, net return and B: C ratio. CSV 20 recorded higher stover and biological yield. Minimum weed density and dry matter at harvest were recorded under intercropping with cowpea+1 HW.
