Abstract:
A field experiment was conducted during 1978-79 at the Agricultural
College Farm, Vellayani, Kerala, to study the effect of different methods of planting
(pit, ridge and furrow) and sizes of planting materials (small cormels of 15-25 g,
size, medium cormels of 35-45 g size, large cornrts of 55-65 g size and corms of
60-70 g size) on the growth and yield of colocasia (Colocasia escufenta (L.)
Schott. Among the different methods of planting, furrow method hastened
germination and increased the plant height, leaf area, LAI, average weight of corm
and total tuber yield. Among the different sizes of planting material, larger size'
groups hastened germination and increased the plant height. Average corm weight
and total tuber yield were the maximum in the case of medium sized cormels.
