Rapid economic and population growth has led to rising atmospheric greenhouse gas emissions, necessitating adequate soil and crop management for enhanced CO2 absorption. Plant and soil microorganisms have various effects on atmospheric CO2 capturing. Chickpea (Cicer arietinum L.), a leguminous plant, establishes a symbiotic association with rhizobium bacteria and mycorrhizal fungi, enabling it to fix atmospheric nitrogen (N2) and sequester more CO2 into the biomass and then to the soil. However, the application type of fertilizers influences this plant’s growth and soil’s capacity to retain carbon (C). In this background, the current research aimed to explore the impact of various organic and inorganic fertilization methods on the growth and nutrient content of chickpea plants and nitrogen content and soil organic carbon. A long-term field trial was started in 1996 at Çukurova University Research Center, with the five treatments such as Control (without fertilizer), Animal manure (25 t ha-1), Mineral fertilizer (NPK), Compost (25 t ha-1), and Mycorrhiza + Compost (10 t ha-1). Chickpeas were planted and harvested in 2020. During harvesting, plant samples at 1 m2 area, and soil samples at 0 to 15 cm and 15 to 30 cm depths were taken. The shoot, root and pod fresh biomass and tissue C, P, K, N, and Zn concentrations were determined. Similarly, the soil P, organic C and total N concentrations were determined. The results of the study indicate that mineral fertilizer resulted in a notable enhancement in the shoot, root and seed biomass of chickpea plants. Furthermore, mineral fertilizer resulted in a higher concentration of carbon in the roots, while the treatments involving animal manure, compost +AMF, and compost showed higher concentrations of K in both shoots and seeds. Seed P concentration was higher when animal manure was applied and exhibited similarity to the compost treatment. In terms of soil properties, the application of animal manure led to increased levels of soil organic carbon and P. Moreover, the compost treatment showed an increase in organic carbon in deeper soil depth. At 15-30 cm soil depth, both animal manure and compost treatments contributed to improved levels of total nitrogen. The good effects of organic fertilizers on soil fertility and nutrient levels in sustainable farming practices are highlighted by these findings. When compared to mineral fertilizer, animal dung specifically showed considerable improvements in soil organic carbon, nitrogen, and phosphorus.
经济和人口的快速增长导致大气中温室气体排放量的增加,因此需要适当的土壤和作物管理来加强二氧化碳的吸收。植物和土壤微生物对大气CO2捕获有不同的影响。鹰嘴豆(Cicer arietinum L.)是一种豆科植物,它与根瘤菌和菌根真菌建立了共生关系,使其能够固定大气中的氮(N2),并将更多的二氧化碳吸收到生物量中,然后进入土壤。然而,肥料的施用类型会影响鹰嘴豆植物的生长和土壤的固碳能力(C)。在此背景下,本研究旨在探讨不同有机和无机施肥方式对鹰嘴豆植物生长和养分含量以及氮含量和土壤有机碳的影响。1996年在Çukurova大学研究中心开始了长期的田间试验,采用5种处理,如对照(不施肥)、动物粪便(25吨公顷-1)、矿物肥(NPK)、堆肥(25吨公顷-1)和菌根+堆肥(10吨公顷-1)。鹰嘴豆于2020年种植和收获。收获时取1 m2面积的植物样品,0 ~ 15 cm和15 ~ 30 cm深度的土壤样品。测定茎、根、荚新鲜生物量和组织C、P、K、N、Zn浓度。同样测定了土壤磷、有机碳和全氮浓度。结果表明,施用矿物肥能显著提高鹰嘴豆植株的茎、根和种子生物量。此外,矿物肥处理导致根系中碳浓度较高,而畜禽粪便、堆肥+AMF和堆肥处理的茎部和种子中钾浓度较高。施用动物粪便时种子磷浓度较高,且与堆肥处理相似。在土壤性质方面,施用动物粪便导致土壤有机碳和磷含量增加,堆肥处理土壤有机碳含量增加,土壤深度越深。在15-30 cm土壤深度,动物粪便和堆肥处理都有助于提高总氮水平。这些发现强调了有机肥料在可持续农业实践中对土壤肥力和养分水平的良好影响。与矿物肥料相比,动物粪便在土壤有机碳、氮和磷方面表现出明显的改善。

Agriculture remains an important economic sector in many developing countries. It is a source of growth and a potential source of investment opportunities for the private sector. Irrigation, therefore, currently plays a less significant role in African agriculture compared to other regions, as Africa’s irrigated cultivated land is much lower than the world average. This research study investigated the impact of irrigation system use in agriculture farming in Rwanda. A multi-stage sampling method was employed, whereby the Nyagatare, Kirehe and Rulindo districts, and three irrigation schemes such as Kagitumba, Nasho and Muyanza were first purposely selected. Finally, a simple random sampling was used to obtain a total sample size of 240 maize farming households, within these three irrigation schemes. The findings indicated that land size was significantly and positively associated with the water pump use. The water pump and sprinkler irrigation system use and farm income were significantly and positively correlated. The water user’s association’s membership and the water pumper drip and sprinkler irrigation systems were significantly and positively correlated. The findings of this research revealed that factors namely family size, education level, fertilizers, irrigation system, farming experience are statistically significant to influence productivity of maize crops at these irrigation schemes. In addition, the results of cost benefit and margin analysis indicated that the Net Farm Income (NFI) per ha at Nasho schme site was largest followed by Kagitumba and Muyanza scheme site was the lowest. However, the benefit cost ratio was the highest (2.3) at Kagitumba site, suggesting that one-dollar of investment at Kagitumba irrigation scheme generates 2.3 dollars of revenue. Some factors in this study were statistically and significant to influence the farmers’ willingness to pay for irrigation water in study areas. After the findings, the researcher suggested that farmers should be encouraged to better use agricultural inputs, high attention should be made on infrastructures in order to sustain and maintain them in long run, farmers should be encouraged to pay for irrigation water, public and private sector should increase investment and expand the drip and sprinkler irrigation system where possible in country.
农业仍然是许多发展中国家重要的经济部门。它是增长的来源,也是私营部门投资机会的潜在来源。因此,与其他地区相比,灌溉目前在非洲农业中所起的作用较小,因为非洲的灌溉耕地远低于世界平均水平。本研究调查了卢旺达农业灌溉系统使用的影响。采用多阶段抽样方法,首先有目的地选择Nyagatare、Kirehe和Rulindo地区以及Kagitumba、Nasho和Muyanza等三个灌溉方案。最后,采用简单随机抽样的方法获得了这三种灌溉方案下240户玉米农户的总样本量。研究结果显示,土地面积与水泵的使用呈显著正相关。水泵和喷灌系统的使用与农户收入呈显著正相关。用水户协会成员数与水泵滴灌和喷灌系统呈显著正相关。研究结果表明,家庭规模、教育水平、肥料、灌溉系统、耕作经验等因素对不同灌溉方式下玉米产量的影响具有统计学显著性。此外,成本效益和边际分析结果表明,每公顷净农场收入(NFI)以Nasho方案最大,其次是Kagitumba和Muyanza方案最低。然而,效益成本比在Kagitumba地区最高(2.3),这表明在Kagitumba灌溉计划上每投资1美元就会产生2.3美元的收入。本研究中部分因素对研究区农民灌溉用水支付意愿的影响具有统计学意义。在研究结果之后,研究人员建议应鼓励农民更好地利用农业投入,应高度重视基础设施,以便长期维持和维护它们,应鼓励农民支付灌溉用水,公共和私营部门应增加投资,并在可能的情况下扩大滴灌和喷灌系统。

The experiment was carried out in a total of 54 pots, with 3 replications according to the randomized plot trial design. In the experiment, broad bean (Vicia faba) plant seeds were planted as plant material. In the experiment, 3 irrigation levels were determined for restricted irrigation (50%, 75%, 100% of the field capacity), 3 levels were determined for mycorrhizal fungus (non-mycorrhizal, G. mosseae and indigenous mycorrhiza), and for biochar treatments, control and 1% biochar were implemented. As a result of the experiment, carbon analyzes of soil and plant samples were carried out. The data obtained in the study were determined to develop better at 100% irrigation level under the conditions of biochar and G. mosseae inoculation. Carbon and nitrogen values were higher in bean plants in pots inoculated with mycorrhiza and treated with biochar. These results imply that increased soil and plant performance under restricted irrigation conditions can result from the application of biochar and irrigation at level I100.
试验采用随机小区试验设计,共设54个盆栽,每3个重复。本试验以蚕豆(Vicia faba)植物种子为种植材料。试验中,限定灌溉3个水平(50%、75%、100%田间容量),菌根真菌3个水平(非菌根、G. mosseae和土生菌根),生物炭处理分别为对照和1%生物炭。根据试验结果,对土壤和植物样品进行了碳分析。研究结果表明,在100%灌溉水平下,生物炭和接种苔藓藓菌的条件下发育较好。在接种菌根和生物炭处理的盆栽中,豆类植株的碳氮值较高。这些结果表明,在限制灌溉条件下,生物炭的施用和I100水平的灌溉可以提高土壤和植物的性能。

The leasehold forestry aims to free the poor from a complicated cycle of poverty by institutionalizing and manipulating the local resources. This study is based on the structured and semi-structured questionnaire and an examination of both published and unpublished records. The study was carried out in 283 Leasehold Forest User Groups (LHFUGs) of the Gorkha district representing 8 different clusters. This study makes a clear effort to identify livelihood improvement in the Gorkha district through leasehold forest by taking into consideration livelihood assets (natural, physical, human, financial, and social). The condition of livelihood capitals in the study area was examined using a judgmental scoring technique that looked at the changes that occurred in five different capitals. Three indicators have been used for each of the assets and scores; +1, -1, and 0 were given to represent improved, degraded, and remained unchanged respectively. A spider web diagram was used to express the change. The results depicted that Chepang, Gurung, and Magar are the predominant indigenous peoples who benefited from the LHF. The result showed the constructive impact of the leasehold forestry program on each asset. The social, physical, human, natural and financial capital received an average total score of 0.778, 0.951, 0.748, 0.589, and 0.722 respectively. The most notable accomplishments were construction and access to the physical capitals including the effectiveness of constructions and advancement of knowledge about community development. Better-managed natural resources can help achieve both conservation and livelihood options.
租赁林业旨在通过将当地资源制度化和操纵,使穷人摆脱复杂的贫困循环。本研究基于结构化和半结构化问卷调查,并对已发表和未发表的记录进行了检查。该研究在廓尔喀地区283个租赁森林用户组(LHFUGs)中进行,代表8个不同的集群。本研究通过考虑生计资产(自然、物质、人力、金融和社会),明确了通过租赁森林改善廓尔喀地区生计的努力。研究区域的生计资本状况使用判断评分技术进行检查,该技术观察了五个不同首都发生的变化。每个资产和分数都使用了三个指标;+1、-1和0分别代表改善、退化和保持不变。用蜘蛛网图来表示这种变化。结果显示,Chepang、Gurung和Magar是受益于LHF的主要土著民族。结果显示了林业租赁项目对各资产的建设性影响。社会资本、物质资本、人力资本、自然资本和金融资本的平均总分分别为0.778、0.951、0.748、0.589和0.722。最显著的成就是建设和获得物质资本,包括建设的有效性和社区发展知识的进步。更好地管理自然资源可以帮助实现保护和生计选择。

Effective nutrient and fertilizer management practices play a pivotal role in sustaining agriculture and mitigating the effects of climate change. These practices have a direct influence on soil fertility and crop productivity. This study investigated the long-term impacts of different phosphorus (P) fertilizer doses (0, 50, 100, and 200 kg P2O5 ha-1) on biomass yield and grain nutrient levels of wheat crops as well as on selected soil properties. The experiment was established in 1998 at the Research Center of Cukurova University in Adana, Southern Turkey. The wheat seeds were sown in October 2020 and harvested in May 2021. The experimental design was a randomized complete block, comprising 12 plots and replicated three times. Soil samples were collected at depths of 0-15 cm and 15-30 cm and subsequently analyzed for total carbon, organic carbon (OC), total nitrogen (TN), and the number of mycorrhizal spores. At harvest, wheat plant samples were collected for evaluating total dry biomass, grain yield and concentrations of potassium (K), zinc (Zn), total carbon (C), and total nitrogen (N) in the grain. The result showed that there was a linear increase in the total dry biomass of wheat, however, grain yield started to decline at P200. The wheat grain nutrient concentrations did not differ significantly across P doses, except for higher concentrations of Zn and K at P50 and higher values of grain C and N at P100. However, there was a linear decrease in Zn concentration as the applied P dose increased. The soil OC and soil TN at 0-5 cm were significantly changed relative to the control. The highest levels of soil OC and TN were observed at P100. The number of mycorrhizal spores did not significantly change with the P dose, but a decreasing trend was observed at higher doses. In conclusion, based on the observed parameters of wheat grain yield, total biomass production, grain nutrient concentrations, and soil OC storage, the application of 100 kg P2O5 ha-1 outperforms other P doses. However, the agronomic efficiencies, soil nutrient balance, and environmental effects of the applied P dose require more research.
有效的养分和肥料管理做法在维持农业和减轻气候变化影响方面发挥着关键作用。这些做法对土壤肥力和作物生产力有直接影响。研究了不同磷肥剂量(0、50、100和200 kg P2O5 ha-1)对小麦生物量产量和籽粒养分水平以及部分土壤性状的长期影响。该实验于1998年在土耳其南部阿达纳的库库罗娃大学研究中心进行。小麦种子于2020年10月播种,2021年5月收获。实验设计为随机完整区,包括12个区,重复3次。在0 ~ 15 cm和15 ~ 30 cm深度采集土壤样品,测定总碳、有机碳、总氮和菌根孢子数量。在收获季节,收集小麦植株样品,评估总干生物量、籽粒产量以及籽粒中钾(K)、锌(Zn)、总碳(C)和总氮(N)的浓度。结果表明:小麦总干生物量呈线性增加趋势,但产量在P200时开始下降;不同施磷剂量下,小麦籽粒养分浓度差异不显著,但P50时Zn和K浓度较高,P100时C和N浓度较高。锌浓度随施磷剂量的增加呈线性下降。0 ~ 5 cm土壤有机碳和全氮与对照相比变化显著。土壤有机碳和全氮含量在P100时最高。菌根孢子数量随P剂量变化不显著,但随P剂量增加呈下降趋势。综上所述,从小麦籽粒产量、总生物量、籽粒养分浓度和土壤有机碳储量的观测参数来看,施用100 kg P2O5 ha-1的效果优于其他施磷剂量。然而,施磷量的农艺效率、土壤养分平衡和环境效应还有待进一步研究。

Phosphorus is one of the most important crop-limiting elements which plays a crucial role in the growth as well as the development of the plant. To meet the crop need and to obtain the efficiency of fertilizer they should be applied in appropriate doses. Thus, an experiment including six different doses of phosphorus as a treatment (0, 20, 40, 60, 80, and 100) kgha-1 was designed to identify the optimum dose of phosphorus for better growth and yield of spring maize. The study was carried out according to one factorial RCBD with four replications of six treatments at Satyawati rural municipality, Khaireni, Gulmi from February-June 2022. Maize seeds (Arun-2) treated with Bavistin were sown by maintaining a spacing of 75*25 cm2. Different observations like biometrical, phenological as well as yield-attributing characters were recorded. The results showed that the different doses of phosphorus significantly affected the recorded parameters. The plant height was found highest (164.92cm) with 100kg P2O5 ha-1 which was statistically similar to the plant height (155.57cm) obtained at 80kg P2O5 ha-1. The longest days to silking and tasseling were found at 0 kg P2O5 ha-1. Likewise, cob length (23.05cm), number of grains per kernel (26.76), and shelling percentage (74.48%) were highest in plants with 100kg P2O5 ha-1and number of kernel row per cob (15.19), number of grains per cob (406.22) 1 and grain yield (6203.29kg ha-1) was highest in plants with 80 kg P2O5 ha-1. The maximum harvest index percentage (38.13%) was obtained in 60 kg P2O5 ha-1. There was no significant variation of treatment on thousand-grain weight. This research showed that the treatment of 80kg P2O5 ha-1 was found to boost the yield of maize by enhancing the growth and yield attributes of maize. Thus, for a better and improved yield of maize 80 kg P2O5 h-1 is recommended in Gulmi.
磷是最重要的作物限制元素之一,对植物的生长发育起着至关重要的作用。为了满足作物的需要和获得肥料的效率,应施用适当的剂量。为此,设计了6种不同磷处理剂量(0、20、40、60、80和100)kha -1的试验,以确定春玉米生长和产量的最佳磷处理剂量。该研究于2022年2月至6月在Gulmi Khaireni的Satyawati农村市进行,根据一因子RCBD进行了四次重复的六种治疗。巴伐菌素处理玉米种子(Arun-2),播种间距为75*25 cm2。记录了不同的生物特征、物候特征和产量属性特征。结果表明,不同磷剂量对记录参数有显著影响。100kg P2O5 hm -1处理的株高最高(164.92cm),与80kg P2O5 hm -1处理的株高(155.57cm)具有统计学上的相似性。在0 kg P2O5 ha-1处理下,出丝和抽雄天数最长。同样,100kg P2O5 ha-1的植株的穗轴长度(23.05cm)、每粒粒数(26.76)和脱壳率(74.48%)最高;80 kg P2O5 ha-1的植株的每芯粒行数(15.19)、每芯粒数(406.22)1和籽粒产量(6203.29kg ha-1)最高。60 kg P2O5 hm -1的收获指数最高,为38.13%。各处理对千粒重无显著影响。本研究表明,80kg P2O5 ha-1处理可通过改善玉米生长和产量性状来提高玉米产量。因此,为了提高玉米产量,建议在Gulmi地区施用80 kg P2O5 h-1。

Our investigation included cabbage leaves for insecticides residue analysis. We had been treated by the formulation acetamipride (Mosiplan 20% SP) and profenofos (Ictacron 72% EC) and residues were estimated by HPLC. The findings demonstrated that for each insecticide, a different amount of residues were recorded over the trial period. Acetamipride and profenofos had early deposits of 0.88 and 1.85 ppm on and in unwashed cabbage leaves, respectively. Acetamiprid and profenofos residues on unwashed cabbage leaves were 0.50 ppm and 1.07 ppm, respectively, after the first day of spraying. These reduced to 0.11 and 0.39 ppm on washed cabbage with tap water. To reduce the concentration of pesticide residues in cabbage leaves, it is vital to wash the leaves with tap water as residue loss increases with the amount of time that has passed after spraying began until the end of the trial period. It indicates that acetamiprid was degraded faster than profenofos. These variations in the rate of disappearance of various insecticides could be related to variations in chemical formulation and structure as well as application rates. The safety time after which cabbage plants sprayed with acetamipride and profenofos may be picked up was the first and seventh days, respectively, according to maximum residues limits (MRLs).
我们的调查包括白菜叶进行杀虫剂残留分析。采用对乙酰氨基虫胺(Mosiplan 20% SP)和丙诺福(Ictacron 72% EC)两种制剂处理,HPLC法测定其残留量。研究结果表明,在试验期间,每种杀虫剂的残留量都不同。对乙酰氨基虫胺和丙诺福在未清洗的卷心菜叶片上和叶片上的早期沉积量分别为0.88和1.85 ppm。喷施第一天后,未洗白菜叶片上的啶虫脒和丙诺威残留量分别为0.50 ppm和1.07 ppm。用自来水洗过的白菜,这两种浓度分别降至0.11 ppm和0.39 ppm。为了降低白菜叶片中的农药残留浓度,用自来水冲洗叶片是至关重要的,因为从喷洒开始到试验期结束,随着时间的推移,残留损失会增加。结果表明,对乙酰咪啶的降解速度快于丙诺福。各种杀虫剂消失率的变化可能与化学配方和结构以及施用量的变化有关。根据最大残留限量(MRLs),施用对乙酰氨基虫脒和丙诺福后的安全采摘时间分别为第1天和第7天。
