    Effect of potassium nutrition on the yield and quality of cassava
    (Department of soil science and agricultural chemistry, College of Agriculture, Vellayani, 1983) Gopalakrishnan Nair, P; Aiyer, R S
    Investigations were carried out as the College of Agriculture, Vellayani to find out the optimum dose and time of application of potassium to conserve in relation to yield and quality. For this purpose a seed culture experiment with nutrient solutions at varying duration of it application and a microplot field experiment with different levels of E were conducted during 1977-80. Before conducting the field experiment, two crops of cassavawere taken in the same plot without applying potassium and thus bringing down the available K to a low level.

    Studies on the salt-affected rice soils of Kerala
    (Division of Agricultural Chemistry, Agricultural College and Research Institute, Vellayani, 1963) Gopalakrishnan Nair, P; Subramoney, N
    A pot culture study was conducted using different salts in different concentrations so as to produce varying conductivities in the soil. The influence of different concentrations of various salts on the growth and yield characteristics of rice were studied. Fourteen typical soil samples from the salt- affected areas in Kerala were also examined for their chemical and mechanical composition.
