    Characteristics of coconut types in orissa
    (2002) Dash, D.K.; Hameed Khan, H.
    A survey was conducted in the coconut growing areas, Sakhigopal, Brahmagiri, Konark and Kakatpur of Puri districts, Orissa. Seventeen forms of tall and dwarf varieties were identified based on size, shape and colour of nuts. Characterization of forms was made base on the vegetative, reproductive and nut characters. Local strain Bana recorded to be superior yielder. Dhanei noted for more number of female flowers and Suryabana for dwarfness and ivory skin colour.

    Collecting coconut diversity of Orissa, India
    (2004-12) Kumaran, P.M.; Arunachalam, V.; Dash, D.K.
    Ten coconut populations of Orissa, lndia were collected from Konark, Sakhigopal and Purl. uuring rne survey, data pertaining to vegetative, reproductive and fruit component characters were recorded on source populations. The same has been subjected to principal component analysis individually for understanding the divergence. Of the three sets of data used, fruit component characters gave very good results with 82 % of variation explained by PC1 and PC2. The accessions Odissi Giant and Bana were found to be distinct considering this data. When we used the characters having high PC loadings in all the three sets of data, the accession Narangi also joined the cluster containing Bana, although only 66% of variation was explained by PC1 and PC2. During recent cyclone that hit the region severely took toll of many humans and perennial plants. This effort conserved most of coconut diversity of the state which otherwise would have been vanished.

    Performance of coconut varieties in sandy soil of coastal Orissa
    (2006) Dash, D.K.; Acharya, G.C.; Garnayak, L.M.
    Performance of coconut varieties on growth, yield attributing characters and leaf mineral content of coconut palms was studied in sandy soil of coastal Orissa. The experiment was conducted at the AlCRP on Palms, Konark with ten varieties. The yield attributing characters were significantly influenced by the variety and season. More number of leaves and spadices production was observed in rainy season. Maximum button shedding was observed within two months of spadix opening. Rainy season spadices experienced least button shedding percentage as compared to other seasons. The leaf N, P, K content was higher in rainy season.

    Root distribution pattern of coconut and its influence on nutrient uptake in littoral sandy soil of coastal Orissa
    (2010) Dash, D.K.; Pattanayak, S.K.; Samal, P.P.
    The perfonnance of two hybrids and their parents considering the good and poor bearing characters of coconut were evaluated at AICRP on Palms, Konark, Orissa to find out the effective root zone and its influence on nutrient uptake and yield. The effective feeder root zone was found within the radius of0-200 cm and at depth of0-60 em from the trunk. The yielding behavior ofpalms had a direct relation to the number ofroots, nutritional status ofroot and the leaf. The bearing palms showed higher level ofleafand root N, P, K and root CRC than the poor bearing palms. The N, P and K content ofroot and root CRC were higher at the surface soil and gradually decreased with increase in depth ofthe profile.
