A 3-year field study was conducted during rainy (kharif) season of 1993-95
to evaluate different planting patterns of maize (Zea mays L.) and soybean
[Glycine max (L.) Merr.] intercropping. All the intercropping patterns were
superior in terms of maize-equivalent yield and income-equivalent ratio (I
ER) values to sole crops. All the intercropping patterns except, I addition
al maize row after every 2 rows of soybean (1:2) also recorded higher monet
ary returns than sole crops. Among different intercropping patterns of maiz
e and soybean, paired maize rows (either 30/90 or 45/90 cm)+2 rows of soybe
an gave the highest total yield, maize-equivalent yield, IER value, net ret
urn and benefit : cost ratio. The maximum value of relative not return (RNR
) over sole maize was computed under paired maize rows (45/90cm)+2 rows of
soybean.
