    Effect of lime, phosphorus and rhizobium inoculation on the growth and yield of cowpea
    (Kerala Agricultural University, 1982) Samuel Mathew; Koshy, M M
    An experiment to study the effects of lime, phosphorus and rhizobium inoculation on the growth and yield of cowpea was conducted at the College of Agriculture, Vellayani during 1979. About 24^ increase in the yield of cowpea could be obtained by the application of lime at 300 kg/ha. Phosphorus application or seed inoculation with rhizobium culture did not produce any beneficial effect on the growth, nodulation or yield of cowpea under Vellayani conditions.

    Sodium chloride nutrition of coconut palms
    (Kerala Agricultural University, 1984) Samuel Mathew; Jose, A I; Narayanan Nambiar, P K; Kannan, K
    An experiment was conducted at the Coconut Research Station, Pilicode, Kerala to study the effect of substitution of potassium applied to coconut by sodium. Twentyfour year old coconut palms grown in laterite soil and which received N,P and K at the recommended dose were selected for the study. Replacement of potassium applied as KCI at the rate of 1000 g K20/palm/year to the extent of 50% or even 75% by Na.,0 applied as NaCI for 5 years did not reduce the yield of nuts. Application of NaCI at this rate for 5 years to the laterite soils of Pilicode receiving fairly good rainfall did not alter the pH, EC and aggregate stability of the soil.
