Title: Influence of intercropping and weed-control measures on dry-matter accumulation and nutrient uptake by sunflower (Helianthus annuus) and groundnut (Arachis hypogaea) and their effect on succeeding maize (Zea mays)
Abstract: An experiment conducted during the spring seasons of 1996 and 1997 revealed that sunflower (Helianthus annuus L.) grown in 1:2 ratio of intercropping recorded significantly higher dry matter. However highest N and P uptake was recorded from. the sole crop. Intercropping suppressed the dry-matter accumulation and N and P uptake of groundnut. Weed-control measures enhanced the dry-matter accumulation of both sunflower and groundnut (Arachis hypogaea L.). Combined application of pendimethalin and 1 hand-weeding recorded the highest dry matter of both component crops. On an average, combined application of both weed-control measures showed 30.5 and 46.0% higher uptake of N and P by sunflower and 222 and 370% by groundnut respectively. Productivity and N uptake of maize (Zea mays L.) was significantly higher when it was preceded by intercropping of sunflower and groundnut. Weeds controlled by both pendimethalin and 1 hand-weeding also enhanced the productivity and N uptake by succeeding maize.
