Item Control of Arecanut Spindle Bug (Carvalhoia arecae Miller and China) Using Granular Insecticides(1976-06) Abraham, V.A.; Sathiamma, B.; Abraham, K.J.; Chandy KurianItem Effect of application of macro and micro nutrients and irrigation on the incidence of yellow leaf disease of arecanut(2007-02-08) Rawther, T.S.S.; Abraham, K.J.A field trial was conducted to study the effect of the application of macro and micronutrients and irrigation on tht incidence of yellow leaf disease of arecanut. NPK and micronutrients were applied in combination. Neither NPK nor micronutrients had any ameliorative effect on the disease while irrigation coupled with manuring maintained the yield at economic level.Item Effect of application of macro and micronutrients and irrigation on the incidence of yellow leaf disease of arecanut(2007) Rawther, T.S.S.; Abraham, K.J.A field trial was conducted to study the effect of the application of macro and microautrients and irrigation on the incidence of yellow leaf disease of arecanut. NPK and micronutrients were applied in combination. Neither NPK nor micronutrients had any ameliorative effect on the disease while irrigation coupled with manuring maintained the yield at economic level.Item Effect of intercultivation on production of arecanut, Areca catechu L.(2007-02-08) Sadanandan, A.K.; George, C.K.; Muralidharan, A.; Abraham, K.J.Effect of intercultivation in areca garden (digging with mammutty once in a year, digging with mammutty twice a year, digging with mammutty once in two years and no digging) was studied for six years (1969-1975) in the alluvial soils of CPCRI Research Centre. Peechi on the productivity of arecanut. Pooled data for six years showed that intercultivation in areca garden did not significantly increase the production of fruit or fruit weight.Item Effect of Palm Density and Levels of NPK Fertilizers on Yield and Quality of Coconut(1978) Abraham, K.J.Item Intercropping in Arecanut helps to build up farmers' economy(1974) Abraham, K.J.Item Microbial Profiles of Arecanut Soils Under Mixed Cropping with Special Reference to Arecanut Yellow Leaf(2007-02) Rawther, T.S.S.; Abraham, K.J.; Achuthan Nair, M.; Jayasankar, N.P.A mixed cropping experiment was started in 1975 in the yellow leaf diseased region of Palode with cow pea, NB 21 and guinea grass crop mixed with arecanut palms. The nitrogen fixing Azotobacter and Beijerinckia and phosphate solubilising microflora were enumerated in the arecanut soils during the years 1976, 1977 and 1978. The yield and disease status of the arecanut palms under mixed cropping were also recorded for the three years starting from 1976-78. The influenc of crop mixing in comparison with the control arecanut palms (palms without any crop mixing) has been discussed with emphasis on yellow leaf disease
