Open publisher page 2 citations

Abstract

Trials were carried out in 1973-75 on brown soil derived from basalt; pearl millet [Pennisetum americanum] was sown at 150 000 plants/ha. Natural weed infestations were allowed to compete with the crop for specified periods. Weed competition reduced grain yields by 35-90%. The first 20-30 days was the most critical period for weed competition which affected tillering and panicle formation. The weeds were mostly annuals and were easily controlled by hand weeding or inter-row cultivation
