Abstract

SUMMARY Under rainfed conditions in north west India, intercropping with soyabean, peanut, greengram and clusterbean reduced sunflower yields by 25–50%. The number of pods per plant and grain yield of the leguminous intercrops were also reduced. The maximum LER (1.05) was obtained from the sunflower–greengram mixture. Intercropping increased the protein percentage of the sunflower but decreased that of the companion legumes. It had no effect on percentage oil content of sunflower.
