A. Krishna et al., Effect of planting pattern and nitrogen on fodder maize (Zea mays) intercropped with cowpea (Vigna unguiculata), I J AGRON, 43(2), 1998, pp. 237-240
A field experiment was conducted during 1991 and 1992 under rainfed conditi
on in clay loam soil with different planting patterns and nitrogen manageme
nt in maize (Zea mays L.)+ cowpea [Vigna unguiculata (L.) Walp.] intercropp
ing and mixed cropping system for getting higher fodder yield. Green and dr
y fodder yields of maize + cowpea mixed cropping at 30 cm (24.36 and 4.32 t
onnes/ha) and 45 cm (20.30 and 3.27 ton nes/ha) were significantly higher o
ver maize alone. Intercropping of maize and cowpea (30 + 60 cm) could produ
ce 8.26% higher crude protein. Nitrogen application had significant linear
response. At 180 kg N/ha green and dry fodder yields of 27.14 and 5.13 tonn
es/ha were recorded. Higher N application lowered crude fibre content.
