The efficacy of common salt, Gramoxone and Regione sprays as pre-harvest desiccants on bajra (Pennisetum typhoides L.) and sorghum (Sorghum vulgare Pars) was studied. Appreciable grain moisture reduction (7.5 to 21.5%) in sorghum had occurred when pre- harvest desiccants were sprayed at different stages of maturity. Moisture reduction in boot leaf and stem was not to this extent. Gramoxone at 0.10% (a.i) was more effective than the other desiccants tried. Moisture reduction was more pronounced in 48 hr than in 24 hr of spraying. The late tillering habit and uneven maturity in rainted bajra make it difficult to adopt pre-harvest desiccation.
