Abstract

Field experiment was conducted during 2000 and 2001, with five levels of NPK (kg/ha) viz., 75:25:75; 100:50:100; 125:75:125; 150:100:150 and 175: 125:175, to find out their effect on growth and yield of elephant foot yam and also to study the effect of intercrop on the growth of main crop. The soil was gangetic alluvial with sandy loam in texture, nearly neutral pH, good water holding capacity and moderate soil fertility status. The maximum plant length (89.5 cm), girth (19.2 cm), diameter of corm (21.32 cm), average weight of corm (2.21 kg) and yield (57.29 t/ha) were recorded with highest NPK level (175:125:175 kg/ha) but maximum canopy spread (123. 1 cm) and breadth of corm (11.64 cm) were observed with NPK level (150:100:150). The growth rate of different vegetative parameters of arecanut in inter-cropped block was more as compared to monocrop block. The results revealed that fertilizer schedule comprising 175:125:175 NPK (kg/ha) may be recommended for obtaining higher yield of elephant foot yam grown as intercrop in the young arecanut plantation without hampering the growth of main crop
