Abstract:
A field experiment was conducted during summer, 2019 and 2020 to study the effect of multi-tier cropping systems in elephant foot yam [Amorphophallus paeoniifolius (Dennst.) Nicolson] for efficient resource utilization and profitability in coastal Andhra Pradesh. The experiment was carried out with ten treatments in three replications. The experiment consist of different multitier cropping systems with elephant foot yam grown as main crop along with eighteen intercrops grown in different treatments. The results revealed that among the different multitier cropping systems elephant foot yam + sweet corn + cowpea (T₇) recorded superior values for dry weight of weeds and weed smothering efficiency when compared to other multitier cropping systems during both the years of experimentation (2019-20 and 2020-21) and in pooled analysis.
