Weeds infestation poses huge threat to agricultural crop production systems and their management in modern agriculture. It is imperative to reduce yield losses and ensure food security. In order to minimize herbicide application, a study was carried out to evaluate the allelopathic potential of leaves extracts tested on weed suppression in wheat crop under rainfed conditions. Leaves extracts of Moringa oleifera, Parthenium hystorophorus and Cannabis sativa alone and in different combinations along with a control (distilled water) were sprayed to explore the allelopathic potential for weed management in wheat-maize cropping system. Foliar application of moringa + parthenium + cannabis leaves extract was the best treatment to reduce the number of leaves, leaf length and shoot length of all tested weed species. Leaf chlorophyll content and photosynthetic rate of weed plants was significantly reduced under exogenously application of leaf extracts. Various phenolic compounds were also detected in parthenium, cannabis and moringa leaf extracts. Maximum phenolic compounds were found in parthenium followed by cannabis and moringa leaf extracts. The combination of leaf extracts of Moringa oleifera (MLE) with Parthenium hysterophorus (PLE) and Cannabis sativa (CLE) (water extract at 3%) was significantly impactful to suppress weeds in wheat and achieve higher wheat growth.

杂草的侵扰对现代农业中的农作物生产系统及其管理构成了巨大的威胁。必须减少产量损失并确保粮食安全。为了最大程度地减少除草剂的使用，进行了一项研究，以评估在雨育条件下对小麦作物中的杂草抑制进行测试的叶子提取物的化感作用潜力。辣木，爬山虎和大麻的叶子提取物单独和以不同的组合以及对照（蒸馏水）进行喷雾，以探索小麦-玉米种植系统中杂草处理的化感潜力。叶面喷施辣木+爬山虎+大麻叶提取物是减少所有测试杂草种类的叶子数量，叶长和枝长的最佳方法。在外用叶提取物的情况下，杂草植物的叶绿素含量和光合速率显着降低。在单性，大麻和辣木叶提取物中还检测到各种酚类化合物。在part草中发现了最大的酚类化合物，其次是大麻和辣木叶提取物。辣木（MLE）的叶提取物与Parthenium hysterophorus（PLE）和大麻（CLE）（3％的水提取物）对抑制小麦中的杂草和实现更高的小麦生长具有显着影响。
