Item The Castor capsule borer Dichocrocis punctiferaus Guen. as a pest of cacao in India(2007-02-08) Chandra Mohanan, R.; Harishu Kumar, P.Item Cultural and manurial practices in cashew(2007-02-08) Harishu Kumar, P.Item Effect of aluminium on the growth of Areca triandra Roxb. in sand culture(2007-02-08) Harishu Kumar, P.Aluminium above 4 mg/1 reduced the growth of areca nut seedlings. Mobilisation of phosphorus from root to shoot was observed above 8 mg/1 aluminium.Item Effect of aluminium on the growth of cashew seedlings (Anacardium occidentale. L) in sand culture(2007-02-08) Harishu Kumar, P.Growth stimulation was observed with aluminium application at 12 mg/l Phosphorus mobilisation was observed from root to shoot above 8 mg Al/1Item Effect of NPK fertilisers and season on the root region microflora in cashew (Anacardium occidentale L.)(2007-02-08) Harishu Kumar, P.; Bopaiah, B.M.; Sreedharan, C.Effect of NPK fertilisers and season on the root region microflora of cashew was studied. Population build up of the microflora interacted conspicuously with the season under various fertiliser treatments. Bacteria and actinomycete population build up was recorded in post monsoon season. Fungal population and urease activity were more during pre-monsoon period. Phosphate solubilisers did not show conspicuous variations.Item Effect of season position and age of leaf on the major nutrient composition of cashew(2007-02-08) Harishu Kumar, P.; Rakiappan, P.; Nair, B.P.; Mohan, E.; Nagabhushanam, S.Item Leaf Nutrient Composition of Areca Palm (Areca Catechu L.) As Influenced by Moisture Stress and its Relation to Yield(2007-02) Harishu Kumar, P.; Yadukumar, N.; Shama Bhat, K.Item Leaf Nutrient Content of Cashew :As Influenced by Different Methods of Fertiliser Application(2007-02) Harishu Kumar, P.; Nagabhushanam, S.Among the three methods of soil application tested, double ring method seems to enable quicker absorption of NPK, closely followed by the pocket method than the traditional method. The leaf tissue concentration for the three major nutrients was also maintained in the two methods at a higher level and for a longer period.Item Nutrient distribution in cashew(2007-02) Harishu Kumar, P.Phosphorus, potassium, calcium and sodium contents of petioles are significantly higher as compared to leaf contents. Bark is found to contribute major portion of calcium and phosphorus to the main pool. An equilibrium is found to hold good among K-Ca - Na in the leaves of flowering and non-flowering shoots. A reduction in the ratios of K/p, Ca/N and Ca/p was observed from July to November in the leaves and petioles. Non-flowering shoot petioles recorded higher ratios of K/p, Ca/N and. Ca/p when compared to flowering shoots.Item Seasonal fluctuations in the major nutrient composition of cashew leaf tissue (Anacardium occidentale L)(1982) Harishu Kumar, P.; Murthy, K.N.; Nair, B.P.Item Standardisation of Leaf Sample Size for NPK Analysis in Cashew(Anacardium Occidentale L.)(1982) Harishu Kumar, P.; Nair, B.P.; Murthy, K.N.Item Variation in mineral composition of leaves of cashew (anacardium occidental L.)as affected by season,position and age(1982) Harishu Kumar, P.; Nair, B.P.; Rakhiappan, P.; Nagabhushanam, S.; Mohan, E.Flowering and fruiting had a depressive effect on the major nutrient composition of cashew leaves Leaves of top portions did not vary in their N P K contents with that of lower portions. Freshly matured leaves, emerged after fruiting recorded higher contents of NPK than the matured leaves of previous season. The variation among the trees with respect to NPK contents of freshly matured leaves is less as compared to older leaves.Item Yellow Leaf Disease Of Arecanut In Soil Fertility Studies(1976) Mohapatra, A.R.; Bhat, N.T.; Harishu Kumar, P.Item Yellow leaf spot of Cashew(1979) Menon, M.A.; Chandra Mohanan, R.; Harishu Kumar, P.; Rakkiyappan, P.; Nair, B.P.
