Item Effect of carbide ash as a liming material on the yield of nuts in coconut palm(Kerala Agricultural University, 1979) Mathai, GItem Effect of fungicides and silica in the control of sheath blight disease of rice caused by Corticium Sasakii (Shiriai)(Kerala Agricultural University, 1981) Mathai, G; Paily, P V; Menon, M RResults of field experiments conducted at Vellayani, Kerala during 1974 indicated that Hinosan was significantly superior in reducing sheath blight disease intensity and in increasing the yield of rice due to better disease control. Application of silioa (250 and 500 kg/ha) had significant effect in reducting the disease intensity on the 75th day of sowing. Crude silica content in the plant was high at the 40th and 80th day of sowing but was low on the 60th day. Positive correlation was observed between the amount of applied silica and the crude silica content of plant.Item Effect of residue salt bitters on the yield and foliar yellowing intensity of coconut palm(Kerala Agricultural University, 1979) Mathai, G; Vasudevan Nair, K PItem Effect of soil application of fertilizers and micronutrients on root (wilt) disease and yield of coconut in the back water region of Kerala(Kerala Agricultural University, 1978) Mathai, G; Vasudevan Nair, K PItem Field evaluation of fungicides against Corticium sasakii (Shirai) matsumoto causing sheath blight on rice(Kerala Agricultural University, 1976) Mathai, G; Varadarajan Nair, PItem Fractional application of fertilizers for coconut Seedlings(Kerala Agricultural University, 1978) Mathai, G; Nair, P P V; Thampi, A MItem Relationship between yield of coconut and rainfall pattern in the back-water region of Kerala(Kerala Agricultural University, 1978) Mathai, G; Panicker, K SItem Studies on the effect of fungicides and silica in the control of sheath blight of rice caused by Corticium Sasakii (Shirai) Matsumoto(Division of Plant Pathology, College of Agriculture, Vellayani, 1975) Mathai, G; Paily, P VA field experiment to determine the effect of two fungicides under three levels of silica on the incidence and intensity of sheath blight of rice was conducted at the Agricultural College Farm, Vellayani during the crop season February to May 1974. The fungicides, hinosan and dithane M-45, were effective in reducing the intensity, per cent infection and rate of spread of the disease and thereby increasing the yield. Among the fungicides tried hinosan was significantly superior. Application of silica was found to have significant effect in reducing the intensity of the disease on the 75th day. However, the per cent infection, rate of spread and the intensity on the 85th day indicated that the effect of silica in imparting resistance to infection by the pathogen was not significant.
