Study of the herbicidal properties of aqueous extracts of Prosopis juliflora leaves on different yield parameters and yield

Millet is Alongside rice, maize and sorghum one of the main cereals grown in Senegal. However, its production still facing some challenges including weed pressure, lack nutrients water soil. This study aims to contribute improvement agricultural groundnut basin through sustainable management. Specifically, we intend to: 1-determine effect Prosopis juliflora extracts on stem growth yield, 2- characterize application date millet cobs stems, 3- determine yield. The treatments were made using 100 g leaf pounded infused 1000 ml for 24 hours. From resulting mixture, two dilutions (5% 10%) applied experimental plots. Each plot received 150 kg/ha nitrogen fertilizer (urea) 2 applications. results shows that Growth yield parameters (number cobs, number weight ears) variate depending year treatments. Yield components are inversely proportional grass cover. We recommend therefore increase concentration carry out a single weeding at beginning cycle order reduce infestation promote better development millet.
