Abstract


An experiment was conducted in Completely Randomized Design (CRD) with seven treatments replicated three times to evaluate the relative efficacy of different seed treatments in controlling bruchids [Callosobruchus chinensis (L.)] and their effect on seed quality parameters during storage of cowpea variety KBC-2. In the storage study of six months, different seed treatments were used viz., Malathion 5 per cent dust, pongamia oil, neem oil, neem leaf powder, sand and ash. Among the different seed treatments it was observed that sand layer of 2.5 cm thick above the seeds stored was found to be effective in maintaining minimum development of bruchid population (3.6 per 100 seeds), 10 per cent seed damage, 3.13 per cent weight loss of seeds, 67.3 per cent seed germination and 20.8 per cent protein content at the end of storage, followed by neem oil treatment
