Abstract

Nine organic amendments, namely, Bishkatali leaf dust, mustard cake, sesame cake, jute seed dust, Neem leaf dust, Neem cake, Neem seed dust, Bankalmi leaf dust and rice husk were used in controlling rice ufra disease in three Boro seasons during 1994-1996. The amendments were applied at the rate of 200 kg/ha except for rice husk (500 kg/ha). All the amendments reduced the damaged tiller, ufra 3 and total ufra significantly and gave higher percentage of healthy panicles and increased yield over control (diseased). In all seasons, due to application of Bishkatali leaf dust, mustard cake, sesame cake, jute seed dust, Neem leaf dust, Neem seed dust, Bankalmi leaf dust and rice husk the yield was increased that ranged from 61.60-67.17, 56.07-71.43, 67.98-75.98, 65.78-78.51, 62.25-76.10, 61.79-79.06 and 62.53-80.16, 61.01-71.43% respectively over the control (diseased). The organic amendments could be used as the alternatives of nematicides for the control of ufra disease.
