The increasing rate of carbon dioxide (CO) emissions and its impact on global warming are a tremendous problem globally. To control these problems, the present research attempted to employ the for growth-dependent enhanced CO sequestration using cattle waste (cow dung, CD and cow urine, CU). Two experiments of growth using six different percentages of CD and CU (0.5, 1.0, 5.0, 10, 20 and 40%) were conducted to determine the optimum doses of CD and CU for the maximum growth of and to assess the growth dependent enhanced CO sequestration of using CD and CU. The maximum growth of was achieved at the doses of 10% CD (weight 2.15 g and number 77.5) and 0.5% CU (weight 2.21 g and number 79.5). The highest rate of CO sequestration was found in the treatments of 10% CD (346.83 mg CO) and 0.5% CU (356.5 mg CO) in both experiments. Due to possessing the huge biomass production and high CO sequestration properties of within a short span of time using the cattle waste (cow dung and cow urine), therefore, it can be concluded that the explored mechanism would be a simple and potentially novel approach in order to sequester the CO and transform into useful plant biomass for the minimization of CO emitting problems in the current global warming scenario.
二氧化碳（CO）排放量的不断增加及其对全球变暖的影响是全球面临的一个巨大问题。为了控制这些问题，本研究试图利用牛粪（牛屎，CD）和牛尿（CU）来实现依赖生长的增强型CO封存。进行了两个使用六种不同百分比的CD和CU（0.5%、1.0%、5.0%、10%、20%和40%）的生长实验，以确定CD和CU的最佳剂量，实现最大生长，并评估使用CD和CU的依赖生长的增强型CO封存。在10% CD（重量2.15克，数量77.5）和0.5% CU（重量2.21克，数量79.5）的剂量下实现了最大生长。在两个实验中，10% CD（346.83毫克CO）和0.5% CU（356.5毫克CO）的处理中发现了最高的CO封存率。由于利用牛粪（牛屎和牛尿）在短时间内具有巨大的生物质产量和高CO封存特性，因此，可以得出结论，所探索的机制将是一种简单且可能新颖的方法，用于封存CO并转化为有用的植物生物质，以最小化当前全球变暖情景中的CO排放问题。
