Abstract:

Glass house pot experiment was performed to test the effect of soil texture and depths on the emergence of seeds of various weeds grow in the fields of wheat. Seeds of different weed species were sown in three different depths (2cm, 4cm and 6cm) of both sandy loam and clay loam textured soil. Pots were fully labeled according to type of species, soil textured class, sowing depths and replicates wise. Pots were placed in the glasshouse in a completely randomized block design. From this study, Avena fatua L. and Vicia sativa L. showed significantly more germination i.e., 46±3.69, 48±3.85 respectively than the remaining four other types of weed seeds. The lowest germination i.e., 20±1.59 was found in the case of Galium aparine L. There were also observed that seed germination (P<000*) significantly decreased with the increase of seed sowing depth. Increasing the depth more and more, decreasing the germination of seeds, because deep sowing seeds were under the less pressure of oxygen, which is very important for the vital activities of seeds. Sandy loam texture soil was best for maximum germination of seeds (P<000*). The aim of experiment was to investigate the suitability of various species seeds under the soil texture and seed sowing depth.
