An experiment was conducted to study the inhibitory effects of leaf and litter leachates (extracts) of kikar (Acacia nilotica) on the germination of wheat (Triticum aestivum) maize (Zea mays), sorghum (Sorghum bicolor), millet (Pennisetum typhodeum), sunflower (Helianthus annus), brassica (Brassica compestris) and taramira (Eruca sativa). Seed germination of all sevel crops was significantly and negatively affected due to the application of extracts as compared to tap water treatment. Highest adjusted reduction in germination (89.67%) was recorded in Sorghum followed by Taramira (85.36%), while maize was least affected (60%).
