Succulent leaves of two accessions of Baobab (Odo-Ere and Okoloke) grown under three poultry manure rates (PM) (0, 15 and 30 t ha-1) were harvested and assayed for proximate, mineral, vitamin and anti-nutrient compositions using standard analytical procedures in replicated trials. Results of the analysis of variance revealed a significant (p<0.05) effect of accession and poultry manure on some proximate, mineral, vitamin and anti-nutrient contents of Baobab leaves. Accession sourced from Okoloke contained higher carbohydrates and protein while Odo-Ere accession had higher moisture content. Application of 15 t ha-1 of PM increased moisture content. The effect of accession was non-significant (p>0.05) on mineral contents. No application of PM enhanced iron, iodine and zinc concentrations. Vitamins B6, E and carotenoid contents were higher in Okoloke. Application of 30 t ha-1 of PM increased vitamin B6 and carotenoids. Odo-Ere produced higher flavonoids, oxalate and phytate while Okoloke contained higher phenol. Application of 30 t ha-1 of PM increased phenol content. Plants grown without PM and plants treated with 15 t ha-1 of PM topped regarding saponin. Biplot analysis revealed wide variability in nutritional qualities of Baobab leaves in response to the combined effects of accession and poultry manure. The results provided further insight into the utilization potential of leaves of Baobab. Furthermore, the results showed that poultry manure application could have a positive impact on the vitamin, proximate and anti-nutrient contents of Baobab leaves.
在重复试验中，采集了两种猴面包树(Odo-Ere和Okoloke)在三种禽粪率(PM)(0、15和30 t hm -1)下生长的多肉叶片，并使用标准分析程序分析了近物、矿物质、维生素和抗营养成分。方差分析结果显示矿物质含量差异显著(p0.05)。没有施用PM提高铁、碘和锌浓度。维生素B6、E和类胡萝卜素含量较高。施用30 t hm -1 PM可增加维生素B6和类胡萝卜素。Odo-Ere的类黄酮、草酸和植酸含量较高，而Okoloke的酚含量较高。施用30 t hm -1 PM可提高苯酚含量。不施用PM的植株和施用15 t hm -1 PM的植株在皂苷含量方面达到最高水平。双图分析显示猴面包树叶片的营养品质在加入和禽畜粪便的综合作用下具有广泛的变异。研究结果进一步揭示了猴面包树叶片的利用潜力。结果表明，施用禽粪对猴面包树叶片维生素、近因营养素和抗营养素含量均有显著影响。

As Syria enters its tenth year of crisis, the problem of food insecurity has increased and has become a critical issue at the local and global levels. The aim of this research is to measure the farm households’ food security status in the coastal area, using a set of internationally approved measures, which are the Food Consumption Score (FCS), the Reduced Coping Strategies Index (rCSI), and the Consolidated Approach to Reporting Indicators of Food Security (CARI). The research relied on collected preliminary field data using a questionnaire form during the months of October and November of 2019, the study was conducted on a random sample of 382 farm households distributed between Lattakia and Tartous governorates based on their percentage of the total number of households. The results showed that the food consumption score gave the lowest level of food insecurity among households, followed by the Food Security Index of the Consolidated Approach to Reporting Indicators of Food Security. While the reduced coping Strategies Index gave the highest level of household food insecurity, where the value of these three indicators was 20.6, 21.6, 47.2% respectively. The study recommended the necessity of using multiple indicators to measure the different dimensions of food security, and that the combination of indicators can improve the measurement of food insecurity, as this reduces the false possibilities, whether positive or negative, and the misclassification of households’ food security status.

In this study, the essential oils from the rhizomes of six species belonging to the Zingiberaceae family, including Zingiber zerumbet, Curcuma pierreana, Globba macrocarpa, Alpinia conchigera, Stahlianthus campanulatus and Amomum sp., collected in Binh Chau-Phuoc Buu Nature Reserve were isolated using hydrodistillation, and their constituents were identified via Gas Chromatography-Mass Spectrometry. A total of 91 constituents have been identified from essential oils. These compounds were classified into 4 clusters by Agglomerative Hierarchical Clustering (AHC) and Principal Component Analysis (PCA) analysis. The principal constituents of the essential oils isolated from four species, C. pierreana, S. campanulatus, A. conchigera, and Z. zerumbet contained camphene (18.82%), α-copaene (11.75%), p-xylene (21.86%), and α-santalene (17.91%), which were significantly different from those in previous reports. Furthermore, this study revealed the chemical constituents of essential oils of G. macrocarpa and Amomum sp. for the first time. Accordingly, artemisia triene (22.21%), β-pinene (13.57%), 4,6,8-trimethylazulene (11.1%), 2-tert-butylquinoline (9.86%), β-patchoulene (7.06%), α-elemene (6.93%), and β-ocimene (6.0%) were the major compounds in essential oils of G. macrocarpa rhizomes whereas the oil of Amomum sp. was found to be rich in 2-carene (21.82%), fenchyl acetate (14.26%), 3-carene (8.28%), bornyl acetate (7.7%), and D-limonene (7.13%).

Paddy fields in Indonesia, on average, have a very low content of organic matter (organic C < 2%). This organic matter’s low content will affect the carbon stock. The management system as well as soil type could affect carbon stock in the soil. This study aims to determine the dynamics and carbon stock in paddy fields with different management systems and soil types. The research was conducted in Karanganyar Regency; Sukoharjo Regency and Klaten Regency. Factors observed include organic, semi-organic, inorganic management systems and soil types (i.e., ultisol, vertisol and inseptisol). Soil sampling was carried out 3-5 days after harvest. Each combination of the management system and soil type was taken with three soil sample points at two depths (0-20 cm and > 20 cm) with three repeats. The parameters hedied include organic C, dissolved organic C, microbial C, pHH2O, total N, CEC, soil texture and bulk density. Soil depth and the interaction of management systems and soil types affect the total organic C. Total organic carbon is highest in vertisol soils with an organic management system (2.59%) and a depth of 0-20 cm (2.24%). Carbon stock (82.62 tons ha-1) in vertisol soils with organic management systems is higher than in vertisol soils with semi-organic and inorganic management systems, with a C stock of 71.19 tons ha-1 and 68.4 tons ha-1.

Land use / land cover is a fundamental variable for the sustainable management of resources as well as for the study and understanding of environmental phenomena. Nowadays, it has become essential in most mapping and monitoring inventories of environmental phenomena. This study aims to assess the changes affecting land use / land cover in the municipality of Dori. The methodological approach is based on the interpretation of Landsat images from three periods (1995, 2006 and 2015). Cartographic data analysis revealed a decrease in the area of natural formations by 16.86% and an increase in anthropized areas by 80%. The matrix of changes made it possible to observe that the tree steppe underwent a more marked transformation of 6.45% into shrub and grassy steppe; 1.42% in rainfed crops. The conversion of shrub / grassy steppes into mosaics of fields is notably observed with a conversion of 13.77%. The study found that human activities are the main drivers of observed changes in land use and occupation in the study area, but variability in rainfall likely also contributed to these observed changes. The results of this study therefore constitute fundamental elements that will help decision-makers in decision-making for the sustainable management of natural resources.

In order to study the effect of different manure and chemical fertilizer levels on qualitative and quantitative characteristics of safflower in the condition of irrigation with municipal wastewater, an experiment was conducted as split plot basis of randomized complete design in Lakhshah region locate in Zahedan city, Iran. The treatments were comprised of two levels of irrigation, W1= Well water and W2= Treated wastewater, in main plots and sub plots consisted of F1: control (without consumption of manure and chemical fertilizer), F2: Recommended manure, F3: Half of recommended manure and chemical fertilizer (N, P and K), and F4: Recommended chemical fertilizer (N, P and K). The results showed that Treatment of treated wastewater had a positive and significant influence on all yield components, and the most influence was shown on 1000 seed weight. Also, irrigation with wastewater significantly increases the dry and fresh yield and grain yield of safflower than ordinary water. Among the fertilizer treatments, complete treatment of chemical fertilizer N, P and K had the greatest effect on increase of yield and grain yield components. In this experiment, water treatment hadn’t significant effect on accumulation of Cr, pb, Fe and Mn in safflower grain, and soil. While, fertilizer treatment had only a significant influence on the accumulation of Fe and Mn in safflower grain, but between these treatments wasn’t saw any significant difference on the accumulation of Cr and pb. In general, the results of this experiment showed that irrigation with wastewater and application of complete fertilizer with manure is recommended.

Dual-purpose barley and wheat production is a valuable resource to fill feed gaps and grain production, but availability at drought and heat stress conditions is still not clearly studied. Two experiments were conducted at semi-controlled green house to determine biomass production at vegetative stages, chlorophyll content and grain yield. Experiment 1 consists of four clipping treatments on wheat, i.e. one, two, three times clipping and un-clipping control. Experiment 2 combined two clipping treatments (one clipping and un-clipping) and two levels of water (low: 40 % of field capacity; normal: 85 % of field capacity) on barley. Wheat grain yield was severely affected by increasing clipping number under heat stress. Total biomass at one clipping was the same level as control treatment. Although physiological maturity was delayed 8 days from control to 3 times clipping application, biomass and yield remained below the control application due to shrinkage in plant height and other organs size. Clipping and water levels at barley significantly impacted biomass and plant height, but all traits were not related by interactions clipping x water level. The clipping application in heat stress reduced total biomass by 21.3 and 30.4 % in well-watered and dry conditions, respectively. Contrary to what is expected, it seems clear to obtain satisfactory forage and grain yield by optimizing the management technique, growing in dual-purpose production in wheat and barley in warm environments.

This study analyzed the effect of plant hormones, zeatin, 6-benzyl amino purine (BAP), kinetin, and thidiazuron (TDZ) on the growth of Tartary buckwheat sprouts and analyzed the fresh weight, shoot and root length, and production of phenolic compounds. All the hormone-treated plants at the lowest concentration (0.1 mg/L) showed the highest levels of growth parameters (fresh weight, shoot, and root length) when compared to the control. Among the various hormones treatment, the plant treated with 1 mg/L of BAP, kinetin, and zeatin showed the highest total phenolic level, whereas the TDZ showed the highest accumulation of total phenolic at the lowest concentration (0.1 mg/L). A total of 6 compounds were identified (4-hydroxybenzoic acid, caffeic acid, chlorogenic acid, p-coumaric acid, rutin, and trans-cinnamic acid) were quantified by high liquid performance chromatography (HPLC) after treatment of plant with different concentrations of hormones. Among these individual phenolic compounds, at the higher hormonal concentration (1 mg/L) the rutin showed the highest accumulation in BAP, zeatin, and kinetin treated sprout, whereas in the TDZ treated sprout the rutin content was highest at the lowest concentration (0.1 mg/L). From these results, it is suggested that BAP, zeatin, and kinetin at the lowest concentrations might positively enhance the growth of buckwheat sprouts, whereas at the highest hormonal treatment the accumulation of the phenolic compounds was higher. However, in TDZ treatment the growth and phenolic compound accumulation were highest at the lowest concentration. From these results, it is showed that suitable concentrations might enhance the growth and phenolic compound accumulation in Tatary buckwheat sprout.

The importance of active and passive remote sensing data integration appears strongly on cloudy days. The lack of passive remote sensing data on cloudy days prevents the benefit of large-scale satellite data in cloudy areas, while the advantage of active remote sensing, it could penetrate the cloud and collect data underneath the cloud. The main objective of this paper is to determine the benefits of combining active and passive remote sensing data to detect actual evapotranspiration (ETa). Sentinel-1 radar data represents active data, while Landsat-8 represents passive data. Multi-date data for Landsat-8 and Sentinel-1 were used during the 2016 summer season. The characteristic soil texture in the study region is clay. The meteorological data were used to estimate ETo based on the FAO-Penman-Monteith (FPM) process, while the Lysimeter data were used to test the estimated ETa. Landsat-8 data are used to measure the Normalized Difference Vegetation Index (NDVI) and the Crop Water Stress Index (CWSI). Crop Coefficient (Kc) is calculated on the basis of NDVI. The CWSI, Kc, and ETo were then used to determine ETa. Backscattering (dB) C-band Synthetic Aperture Radar (SAR) data extracted from the Sentinel-1 satellite was correlated with Kc and used to estimate ETa. The Root Mean Square Error (RMSE) reported relevant results for active and passive satellite data separately and the combination process. For Sentinel-1, Landsat-8 and combination methods, the RMSE reported 0.89, 0.24, and 0.31 (mm/day) respectively.
