    Comparative study of certain fruit qualities of twenty pineapple varieties
    (Kerala Agricultural University, 1978) Gopimony, R; Balakrishnan, S; Marykutty, K C
    A study was undertaken to evaluate the fruit quality of twenty pineapple varieties during the fruiting season of 1975-76 at the Pineapple Research Centre, Vellanikkara, Trichur. In fruit weight, Kew was found to be far superior to all other varieties except Smooth Cayenne. But in certain other dessert qualities like colour and texture of flesh, flavour, sweetness and T. S. S. varieties like Mauritius, McGregor, Ripley Queen, Queen and Valerabalanga were found to be superior to Kew. The variety Valerabanga was found to show a superior sugar-acid blend as compared to Kew. This suggests its use as a parent material in breeding works for further improvement of Kew.

    Effect of nitrogen nutrition on quality and storage behaviour of pineapple
    (Kerala Agricultural University, 1980) Balakrishnan, S; Aravindakshan, M; Marykutty, K C; Valsamma Mathew
    In studies on the effect of different levels of nitrogen nutrition on fruit quality and storage behaviour of pineapple, it was found that at harvest, the maximum reducing sugars, brix to acid ratio and sugar to acid ratio were registered at lowest level of nitrogen at 8g/plant As the level of nitrogen was increased to 12g/plant, total sugars increased, but there was a decrease as the level was further increased to 16g/plant. Acidity and TSS showed an increasing trend with increasing levels of nitrogen. During cold storage, higher levels of nitrogen recorded a decrease in reducing sugars. Maximum increase in acidity was recorded by the lowest level of nitrogen under both storage conditions. Increase in nitrogen level upto 12g per plant was found to have a favourable influence on total sugars in both open and cold storage conditions. Better retention of brix to acid ratio in cold storage and to reducing sugars in open storage was observed when the nitrogen dose was increased to 16g/plant.

    Screening of rice varieties for tolerance to acidity
    (Kerala Agricultural University, 1986) Marykutty, K C; Aiyer, R S
    A pot culture experiment wss conducted to screen out the most tolerant variety that could be grown in a highly acid soil from among 39 varieties cultivated in Kerala. The varieties were screened for tolerance to acidity using the method of D2 statistics, selecting the important characters and thus three clusters were formed. They were characterised as tolerant, medium tolerant and least tolerant varieties to acidity. Among the tolerant varieties, Jyothi variety ranked first.

    Residual effect of liming on soil characters
    (Kerala Agricultural University, 1987) Marykutty, K C; Aiyer, R S
    A pot culture experiment was conducted to study the residual effect of liming under continuous cropping to rice for 4 seasons with four different soils on soil characters. Soil reacidification rate was found to increase with the increasing levels of lime showing thereby that high rate of liming could cause reacidification problems defeating the very purpose of liming.

    Yield response to lime and residual effect of liming - A statistical evaluation
    (Kerala Agricultural University, 1992) Marykutty, K C; Aiyer, R S
    A pot culture experiment was conducted to study the residual effect of liming under continuous cropping with different soils on crop yield especially in terms of residual response patterns. The residual effect of liming is very much in evidence in the second succeeding crop for kole and kari soils and up to third crop for pokkali soils. In case of lateritic alluvium, application of lime at 0.25 LR has resulted in maximum yield. Response function for the first crop and residual response function for the second crop could not be worked out. This indicates that maximum yield might have been attained at a level of liming below 0.25 LR dose.
