Hydroponic cultivation of kesum using deep water culture (DWC) system can be an alternative option for kesum growers in increasing crop yields. The deep water culture system is a method in which liquid fertiliser solution is given directly to the plant roots without any medium and water flow. The study’s main objective was to determine the effects of nitrogen concentration on growth, yield and phytochemical content of kesum cultivated using hydroponic system. Plants were grown under one of four nitrogen concentration solution regimes and the experiment was conducted under a side netted rain shelter. The four treatments comprised of 200 mg/L, 100 mg/L, 50 mg/L and 0 mg/L of nitrogen concentrations. The experiment was arranged in Randomized Complete Block Design (RCBD) with 4 replications. Plants were selected randomly and harvested eight weeks after planting. Plants grown supplemented with 100 mg/L of nitrogen concentration gave the best growth performance and biomass yield. They produced the highest plant height (78 cm) and fresh biomass yield (174 g per plant). Meanwhile plants supplemented with 50 mg/L of nitrogen concentration produced the highest Quercetin-3-glucuronide (Q3G) (98.261 mg/mL) and Quercitrin (61.367 mg/mL) compound compared to the other treatments. However, plants treated with 0 mg/L of nitrogen concentrations exhibited major nutrients deficiencies symptoms and die after 3 weeks of planting. Hence, it can be concluded that the kesum plants cultivated using hydroponics’ deep water culture system supplemented with 100 mg/L of nitrogen concentration gave the highest plant growth and biomass yields. However, to obtain higher Quercetin-3-glucuronide and Quercitrin compound, 50 mg/L of nitrogen concentration is recommended.","PeriodicalId":299553,"journal":{"name":"Asian Journal of Soil Science and Plant Nutrition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130006100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kuntze) is a highly valued plant known for its refreshing taste, medicinal properties, and health benefits. It is an evergreen shrub or small tree belonging to the Theaceae family. The productivity and quality of tea leaves and liquor are strongly influenced by edaphic and environmental factors. However, the cultivation of tea faces significant challenges due to the increasing occurrence of drought associated with global warming and climate change. In this review, we have summarized the potential effects of drought on the growth, productivity, and liquor quality of tea. Drought exerts substantial impacts on the physiological, biochemical, and morphological features of tea plants. For instance, under drought stress, there is a reduction in leaf activity, including chlorophyll production, photosynthetic rate, and CO2 uptake. Drought periods also lead to decreased shoot initiation and extension rates. However, it is important to note that responses to drought can vary depending on factors such as tea variety, cultivar diversity, agricultural management practices, and study techniques. While drought-induced biochemical damage may occur, it is often reversible, and the plant can recover upon rehydration. Irrigation strategies employed during dry periods have been shown to have a significant positive effect on tea yields, making it a promising option for enhancing productivity in drought-prone regions. Furthermore, the cultivation of drought-tolerant tea cultivars, along with the application of micro and macro-nutrients, as well as hormone treatments, can contribute to improving the post-drought recovery process. Studying the influence of drought on tea productivity offers an opportunity for frontier research, aiming to understand the intricate relationship between tea leaf productivity and liquor quality. Additionally, investigating the factors that contribute to stress recovery in tea plants holds promise for enhancing cultivation practices and ensuring the sustainability of tea production in the face of changing climatic conditions.","PeriodicalId":299553,"journal":{"name":"Asian Journal of Soil Science and Plant Nutrition","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133021119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was arranged in a split-plot design with three replicates. Data indicated that applying compost treatment appears to be more successful in reducing pH and bulk density of soil than biochar. Application of biochar treatment reduced electrical conductivity meanwhile, compost increased it. Hydraulic conductivity, total porosity, organic matter content, moisture constants of soil,  cation exchange capacity were increased by applying all tested soil amendments in two seasons. All Soil amendments caused a marked improve in soil available nitrogen, phosphorus and potassium content. Meanwhile, compost treatment was the best one in increasing available nitrogen and potassium content. Compost application with all foliar spray had given a first order while foliar application under biochar addition had the second one. Data investigated that potassium silicate treatment increased grain & straw yield, harvest index, yield efficiency, 1000 grain weight, carbohydrates and protein. It is clearly observed that compost with potassium silicate treatment was superior to biochar with all foliar treatments of increasing nitrogen, phosphorus, and potassium concentration of grain and straw yields and its uptakes.","PeriodicalId":299553,"journal":{"name":"Asian Journal of Soil Science and Plant Nutrition","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114695897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, their manufacturing is an energy-intensive process which causes greenhouse gas emissions, which can lead to climate change. Therefore, it should evaluate the possibility to use organic sources such as Azolla as a partial substitute for synthetic nitrogen fertilizers in cultivation, as this may reduce the cost of fertilizer inputs, and promote sustainable agriculture. So, a field trial was carried out in the Tag El-Ezz Experimental Farm (30°56' 12.88\" E longitude and 31°31' 47.64\" N latitude) during seasons of 2021/2022 and 2022/2023 to assess the additive of nitrogen recommended dose (NRD=178.6 kg N ha-1) as combined treatments of urea (46.5%N) as mineral nitrogen source and Azolla (4.0 %N) as organic nitrogen source. Also, the exogenous application of zinc (zinc sulfate, 22.8% Zn) and copper (copper sulfate, 21.8 %Cu) was evaluated. The tested plant was wheat (Cv. Giza 171). The nitrogen treatments [T1: 100% of NRD as urea (control),T2:75% of NRD as urea+25% of NRD as Azolla,T3:50% of NRD as urea+50% of NRD as Azolla, T4: 25% of NRD as urea +75% of NRD as Azolla and T5: 100% of NRD as Azolla] represented the main plots, while exogenous application of the studied elements [F1: control (without spraying),F2:Zn (at rate of 200 mgL-1) and F3: (Cu at rate of 20 mgL-1)]  represented the sub main plots. The findings illustrate that wheat plants grown under T2 treatment had  the highest values of growth performance (e.g., fresh and dry weights and total chlorophyll), yield and its components (e.g., grain yield, spike length and weight of 1000 grain) and biochemical traits (e.g., carbohydrates and total protein) compared to the corresponding wheat plants grown under other  studied N treatments, as T1 treatment (control) came in the second order followed by T3 treatment, while T4 and T5 treatments came in the last order, respectively. Regarding the external applications, the cu foliar application was the superior treatment followed by Zn treatment, while the control treatment came in the last order. Generally, the maximum values were recorded under combined treatment of (T2xF3). On the other hand, some soil fertility parameters like A-N, A-P and A-K were affected due to all studied treatments. Finally, it can be concluded the possibility of using Azolla as a partial substitute for synthetic nitrogen fertilizers. Also, the obtained results confirm the vital role of both Zn and Cu in wheat plants.","PeriodicalId":299553,"journal":{"name":"Asian Journal of Soil Science and Plant Nutrition","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124617667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The financial benefits of tin mining were short-lived and cannot be quantified with the consequences of its devastation, which is still negatively impacting on the environment. Many of the devastated lands were abandoned due to soil infertility. Smallholder farmers are battling with restoring soil fertility for crop production. This study was conducted on smallholder farms in a devastated and abandoned area due to tin mining of the Bukuru-Rayfield, Sabon-Gida mining zone of Jos Plateau where contrasting organic interventions by farmers were observed. This was also confirmed by laboratory and geostatic spatial variation. A total of 35 soil samples were taken at a depth of 0-20cm, prepared and analyzed in the laboratory.  Continuous surfaces were later generated through geostatistics. Results indicated that organic matter had significant negative correlations with exchangeable acidity (-0.879), clay (-0.633) and silt (-0.616) but significant positive correlations with potential hydrogen (pH) (0.885), nitrogen (N) (0.991), phosphorus (P) (0.954), potassium (K) (0.911), calcium (Ca) (0.920), magnesium (Mg) (0.911) and sand (0.824). Most of these correlations were done at 0.01 level of significance. High concentration of pH, organic matter (OM), N, K, Ca, Mg and sand occurred in the north western part of the study area (Farm A). In contrast, exchangeable acidity, silt and clay had less concentration in the north western part of the study area (Farm A), with highest concentration in the W and SW parts (Farm C). Spatial variability from geostatistics indicated that all the soil variables had strong spatial dependency. The results of this study unveiled that nutrients needed for higher productivity were made available by the smallholder farmer of farm A through dumping of households’ domestic wastes for ten years. These abandoned mining sites later became agriculturally productive. This study will serve as advisory to smallholder farmers as a way of improving soil productivity in tin-devastated farmlands.","PeriodicalId":299553,"journal":{"name":"Asian Journal of Soil Science and Plant Nutrition","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130417971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various soil parameters such as sand, silt, clay content, CEC, ESP OC, ECe, pH, and CaCO3 were determined. Afterward, the geostatistics approach using ordinary kriging interpolation and semivariogram was applied to produce a spatialized and detailed map for each soil parameter. Spherical, Exponential, Gaussian, and J-Bessel geostatistical models were used to define the spatial variability of soil properties based on RMS, MSE, and RMSSE. Based on the TOPSIS method, the soil quality index (SQI) and its ranking under land use types in the study area were calculated. The results of SQI ranged from 38.75% to 55.82% and 27.53% to 52.72%, and 5.75% to 26.73% for old cultivated, new cultivated, and desert soil, respectively. The SQI was classified into three regions. The first has a fair quality index and covers 56.48% (403.91 km2) of the total geographical area (TGA). The soils of this region are located mainly in old cultivated soils and some new ones. The second region was observed in some newly reclaimed soils and desert soils and extended over an area of about 27.75% (198.45 km2). These soils have low values of favorable studied indicators, leading to negative effects on the SQI that are defined as poor. The third region is very poor quality, covers about 15.77% (112.78 km2) of TGA, and is located mainly in desert soils with low beneficial and high non-beneficial studied indicators.

However, the use of herbicides as a means of control presents significant risks for human health and the environment. The abandonment of these products for more ecological alternatives such as cover crops is imminent. Aims: This study aimed to compare the relative abundance and the density of the main plant-parasitic nematodes in the roots of banana and cover crops according to three weed management treatments. Study Design and Methodology: The experimental design was a three-repeat Fisher block of three treatments consisting of implementation of A. repens and D. adscendens as cover crops and spraying of two synthetic herbicides (glufosinate and glyphosate) for weed management. The relative abundance and density of nematodes in the roots of banana and cover crops were assessed quarterly after extraction by the rapid double centrifugation-flotation method and enumeration under an optical microscope. Results: Both cover crops and banana plants had their roots infested by the major parasitic nematodes evaluated (Radopholus similis, Pratylenchus spp., Helicotylenchus spp., Meloidogyne spp., Rotylenchulus reniformis and Hoplolaimus pararobustus). These infestations were not a function of weed management treatments. Compared to the use of herbicides, A. repens and D. adscendens used as ground cover did not significantly increase or decrease nematode dynamics in the plots. Individuals extracted from the roots of the cover crops, and particularly from D. adscendens, were more numerous than from the roots of the banana plants. In terms of proportions, Pratylenchus spp., R. similis, Helicotylenchus spp. and Meloidogyne spp. were most abundant. R. reniformis and H. pararobustus as well as various nematodes (plant parasites: Hirschmanniella spp., Xiphinema spp., ..., and non-plant parasites: fungivorous, carnivorous, bacterivorous, ...) were in the minority.
