摘要

本研究于2020-2021年农季在Al-Muthanna省中部东北43 km的Al-Najmi区农业推广站进行了田间试验,以确定耕作深度和不同肥料组合对小麦(Triticum aestivum L.)某些性状及其杂草竞争的影响。试验采用双因子分割区设计,设3个重复。第一个因素;4种耕作制度(0、10、20和30 cm)处理。第二个因素;对照处理(P0 K0、P25 K30、P50 K60、P75 K90、P100K120 kg hm -1)的施肥组合。研究结果表明,不同耕作制度处理在大多数研究性状上差异显著,杂草减少。耕深为10 cm的处理,植株氮磷平均浓度最高。结果还表明,施肥组合F4在使植株氮、磷、钾平均浓度最高方面具有优势。

The effect of different tillage systems and fertilizer combinations on wheat ( Triticum aestivum L.) growth and some of yield components and its weed Competition
A field experiment was conducted during the agricultural season 2020-2021, at the agricultural extension station in Al-Najmi district, 43 km northeast of the , the center of Al-Muthanna Governorate, to determine the effect of tillage depths and different fertilizer combinations on some traits of wheat ( Triticum aestivum L.) and its weed competition. The experiment was applied according to the arrangement of the split block by two factors using the (RCBD) design and with three replicates. The first factor; four treatments of the tillage systems (0, 10, 20 and 30 cm). The second factor; fertilizer combinations with the control treatment (P0 K0 ,P25 K30 ,P50 K60,, P75 K90,P100K120 kg ha-1). The results of the study showed a significant difference for the treatments of tillage systems in most of the studied traits, weed decreased. The treatment of tillage depth of 10 cm was superior in giving the highest average concentration of nitrogen and phosphorous in the plant. The results also showed the superiority of the fertilizer combination F4 in giving the highest average concentration of nitrogen, phosphorous and potassium in the plant.
