Abstract

Yield, yield components, juice quality as well as competitive rela-tionships and economic evaluation of sugar-cane in response to inter-cropping with sorghum and soybean under different row spacings were investigated during 1995/1996 and 1996/97 seasons. lntercropping soybean or sorghum with spring sugar-cane reason‌ably improved number of intemodes/stalk, stalk weight, Brix%, sucrose %, fiber % and land equivalent ratio (L.E.R), while reduced number of millable cane, cane yield, top yield, purity%, sugar yield and monetary re‌turns. Sugar recovery did not alter with intercropping compared with pure stand of sugar-cane. Agressivity value of sugar-cane was positive for soybean and for sorghum was negative under intercropping systems. Increasing row spacings of sugar-cane was followed by an in-crease in stalk weight and a reduction in the number of millable cane, cane yield, top yield, sugar yield, monetary returns. The other studied characters did not change. It is clear that intercropping sorghum with sugar-cane was more profitable than soybean in respect to the monetary returns.
