dc.description.abstractAmong the diseases affecting areca palm (Areca catechu L), yellow leaf disease is one of the most important diseases based on the nature of the disease and extent of damage. Its etiology is unknown. During the present survey, 18 per cent of the palms in Trichur district (Kerala State) were found to be affected by the disease. The severity of the disease varied. In areas where the water table was above 7-5/77, the disease was noticed in 20 per cent of the palms- In areas where the water table was 1.5 to 3m below ground level the disease was observed in 20 per cent of the palms and only in 12 per cent of the palms where the water table was below 3 m. Log-likelihood ratio test conducted to examine the relationship between water table and disease incidence showed that the disease incidence was not independent of water table.en_US
