Abstract:
A field experiment was laid out in a zinc deficient soil in Kuttanad area,
Alleppey district, Kerala to study the effect of different levels and methods of zinc
application with and without lime, on the growth and yield of rice. Foliar application
of Q.5% and soil application of 20 kg/ha zinc sulphate resulted in significantly
higher yield of grain. Root dip treatment with zinc oxide suspension recorded
an increase in grain yield over control. The effect of application of lime
alone and in combination with zinc, however, could not result in a significant
increase in the yield of grain or straw. The study revealed the importance of
zinc application to rice grown in the water-logged acid soils of Kuttanad.
