Abstract:
The study was conducted to determine the effect of intercropping corn on the growth and yield of different cassava varieties at San Carlos City, Pangasinan; identify the cassava variety which responds best to intercropping with corn based on growth and yield; determine the interaction effect of cropping system and cassava varieties; and determine the profitability of growing different cassava varieties under different cropping systems.
Cropping system did not significantly affect the growth and yield of cassava varieties. Among the cassava varieties, Rayong 5 emerged 12 days after planting (DAP) while Lakan 2 and Golden Yellow emerged a day earlier. Rayong 5 had the highest yield, highest dry matter content and highest return on cash expense.
There was no significant interaction effect of cropping system and varieties on the growth and yield of cassava.
Intercropping cassava with corn had higher return on cash expense compared to monocropped cassava. Specifically, Rayong 5 intercropped with corn gave the highest return on cash expense.
