Agriculture, Vellayani during December 1997 to September 1998 to study the
possibility and extent of substitution of K by Na in banana var. Nendran.
Substitution of K was tried at four levels viz., 25, 50, 75 and 100 per cent of
the recommended dose. The important growth characters of the crop viz.,
height and girth of pseudostem, total number of leaves, total leaf area and leaf
area index showed an increasing trend upto 50 per cent substitution of K by
Na. The total drymatter production was significantly higher upto 50 per cent
substitution. The maximum value for bunch yield was recorded by the
treatment T3 (50 per cent KCI + 50 per cent NaCl). The lowest yield was
registered by the treatment T6 which received no potassium and sodium.
Total and reducing sugars were highest for the treatment T 5 (100 per
cent substitution). Non reducing sugars was highest for POP recommendation.
Shelf life did not show significant variation among the treatments.
Uptake of nitrogen was highest for the treatment T 2. But the P uptake
was maximum in the treatment T3. Maximum value for available nitrogen was
recorded by the treatment T\. Available P was highest in T3. T\ registered
maximum value for available K while T 5 maximum for available Na.
Significant positive correlations were obtained between the uptake of
nutrients and bunch weight. Quality characters also showed significant
correlations between the uptake of nutrients. The highest benefit: cost ratio was recorded by the treatment T 3.
From this study it is to be concluded that there is a possibility of
substitution of potassium by sodium to a level of 50 per cent in banana var.
Nendran without much deleterious effects especially on the yield and quality of
the fruits.
