    Effect of liming on available nutrients and yield of paddy in the acid soils of Kuttanad
    (Kerala Agricultural University, 1974) Kabeerathumma, S; Money, N S
    The significance of lime application to the acid paddy soils of Kuttanad with respect to enhancing available nutrients and yield of paddy varieties was studied. Lime application apart from correction of harmful effects of acidity, increases the availability of essential nutrients and provides better conditions for their assimilation thereby resulting in enhanced yields of rice. The study has also brought out the inherent difference in the nature of acidity between Kari and Karapadom soils and in their capacity for utilisation of applied fertilizers.

    Performance evaluation of banana cultivars in the reclaimed alluvial soils as intercrop in coconut gardens
    (Kerala Agricultural University, 1995) Alice Antony; Inasi, K A
    Field experiments with different banana cultivars were conducted during the period 1988-92 in the coconut gardens of the Regional Agricultural Research Station, Kumarakom, Kerala to identify promising dessert and culinary types having good performance in the plant and ratoon crops. The results revealed that Palayankodan (AAB) was the host suited dessert cultivar for intercropping in coconut gardens since it gave the highest yield and highest net returns per ha in plant and ratoon crops. The study also indicated the suitability of Bathesa (ABB) and Monthan (ABB) the culinary types, for coconut gardens.

    Characterisation and classification of wetland soils of north Kuttanad
    (Kerala Agricultural University, 1997) Manorama Thampatti, K C; Jose, A I
    Fifteen profiles representing acid saline soils of North Kuttanad were studied for their characterisation and classification. Soils were light grey to dark brown / black in colour, sticky and plastic, subangular blocky in structure, and sandy to clayey it) texture, with random deposits of lime shells and organic matter. Faint to prominent reddish yellow or brown mottles were observed from surface downwards. Soils were highly acidic (pH 4.0-5.0) and mildly saline (EC 0.33-1.39 dS m'). Both acidity and salinity increased with depth. The soils were high in organic carbon, CEC and ECEC, but base saturation was less than 50 per cent. Taxonomically, 93 per cent of North Kuttanad belongs to the soil order Entisol and seven per cent to Inceptisol. At subgroup level, 78 per cent of the area is occupied by Typic Sulfaquent and seven per cent each by Fluventic Dystropept, Typic Tropofluvent, Typic Fluvaquent and Typic Tropopsamment.
