The Tropical Agriculturist. The Agricultural Journal of Ceylon February 1939

1939

The longer the toddy is kept before boiling the greater is the degree of inversion and fermentation and the poorer the storage capacity of the jaggery. [...] Furthermore it is only the aboveground portions of the plants which can be utilized and in the case of leguminous plants the nitrogen fixed by the bacteria in the root nodules of such plants cannot be supplied to the paddy crop owing to the difficulty of uprooting the complete plants from outside and turning them into the soil of the paddy field. [...] It is possible however that a legume may be found adapted to the conditions in paddy fields during the early stages of the growth of the paddy as in the case of the latter crop their roots are not of the true aquatic type but they are able to thrive because the algae in these fields are able to liberate oxygen which is utilized by the roots of the paddy plants. [...] The green manure seed was sown (a) mixed with germinated paddy at the time of sowing the paddy (b) prior to the ploughing of the field in preparation for sowing paddy (c) before the harvest of the paddy and (d) after the harvest of the paddy. [...] The removal of the protection either in the form of the natural vegetation or of the crop itself at once91 exposes the soil to the tropical sun and to rain.
