Study on the Effect of Seedbed Types, Urea Fertilizer Rates and Intercropping of Sorghum with Legumes on Striga Incidence

June 14, 2021 Agricultural Sciences 0

Sorghum is important for its grain, which is used as food, animal feed, seeds, and in the brewing of local bear. Its stalks are used for shelter, animal feed, and as a source of sugar at times. Damazin Research Station, Damazin (Latitude 11°47’34N, Longitude 34°21’55 E) and approximately 343.01 meters above sea level (MSL) for two consecutive seasons 2006/07 and 2007/08. There were three kinds of seed beds used. In a Striga-infested field trial, these were flat (control 1), normal ridged, and tied ridged. The purpose of this study was to determine the prevalence of witch weed (Striga spp.) and the performance of sorghum under various treatments. The procedures were followed: two rates of urea fertilizers were applied at 103.5 and 207.0 kg/ha; four leguminous plants, namely Bambara nuts (Vigna subterranea L. Verdc.; Groundnuts (Arachis hypogoea L.); Clitoria (Clitoria ternatea); and Desmodium spp.) were intercropped with sorghum, Sorghum bicolor L. Moench (cv. Wad Ahmed) and Standard ridged seedbeds effectively reduced Striga population and dry weight, according to the results. Clitoria spp. is a legume. Intercropping with sorghum significantly reduced sorghum height, and the application of urea fertilizers, regardless of rate, increased sorghum grain yield as well as Striga population.
