The Impact

Nickel is an essential element for normal physiological functions in plants. At higher doses (>50 mg/kg, as per WHO) it is toxic to plants and humans, which can bring about oxidative stress affecting the physiological functions of plants and is also considered carcinogenic to human beings. To manage nickel pollution in environment, proper chemical or phytoremediation techniques are required. In this regard nickel accumulator plants would offer a cost effective and environmental friendly phytoremediation method. In the present study, the nickel phyto-accumulation potential of Amaranthus viridis from soil was evaluated to check the tolerance level and the impact on selected morphological parameters like total biomass, plant height, root length and number of leaves. Nickel uptake by A. viridis was studied from Ni contaminated soil amended with20, 40, 60, 80 mg/Kg of Ni exposure under controlled conditions. Toxic effects and tolerance of the plant to toxic doses of nickel was evaluated by correlating the uptake per gram of biomass with various parameters of plant like its height, biomass, root length and, number of leaves.  Supply dependent maximum nickel uptake of 108 µg/gm and corresponding decrease in growth parameters were recorded up to 60 mg/Kg exposure. This study indicates the uptake of nickel by A. viridis increases with increase in supply up to 60mg/kg and beyond 60 mg/kg, the uptake decreases. The study also shows uptake of nickel per gram of biomass has a significant  negative correlation mainly with parameters like plant height (R= -0.71 at 0.05 level of significance) and total biomass (R = -0.83 at 0.05 level of significance) where as other parameters like length of root and number of leavers are not significantly affected (P>0.05) with uptake of nickel per gram of biomass.

Research was carried out to evaluate the effects of individual and combined application of organic, NPK (15:15:15), organic plus NPK (15:15:15), fertilizers on the growth parameters of tomato (Lycopersicon esculentum. Mill) in the greenhouse condition of The Oke – Ogun Polytechnic, Saki (Derived savannah), Oyo State, Nigeria. Study was conducted in complete randomized design (CRD). Treatments were at four levels and replicated three times. The soil used was loamy sand. Results showed that the highest average number of leaves (140), number of roots (136), root girth (19.3 cm) and root length (40.8 cm) were achieved in organic plus NPK, highest average plant height (78.4 cm) and stem girth (7.6 cm) was achieved at 50 gm level of NPK (15:15:15) fertilizer treatment, while the highest average leaf area (45.6 cm2) was achieved at 50 gm level of organic fertilizer, the control values were far reduced compared to other levels of treatments. The analysis of variance indicated that organic fertilizer, organic plus NPK (15:15:15) fertilizers had significant (p ≤ 0.05) effects on number of roots, plant height, stem girth, root girth, leaf area, root length and number of leaves. NPK (15:15:15) fertilizer had significant (p ≤ 0.05) effect on number of leaves, plant height and leaf area and no significant (p ≤ 0.05) effects on number of roots, stem girth, root girth and root length, however, 50 gm level of treatment of organic fertilizer had distinct improved significant (p ≤ 0.05) effects on four (4) growth parameters; number of leaves, stem girth, root girth and root length when compared with other levels of treatments for NPK (15:15:15), organic plus NPK (15:15:15) fertilizers, therefore, 50 gm level of organic fertilizer could be applied for better production of Tomato (Lycopersicon esculentum. Mill) in a loamy sand soil.

The study investigated the response of tree seedlings to different pot thickness. Chrysophyllum albidum G. Don (Ericales: Sapotaceae) seedlings were subjected to four treatments, T1 = 0.01 mm pot polythene thickness, T2 = 0.02 mm polythene pot thickness, T3 = 0.03 mm polythene pot thickness, T4 = 0.04 mm pot polythene thickness, 0.01 mm served as control. There were four treatments replicated five times making a total of twenty seedlings altogether. The experiment was arranged in Randomized Complete Block Design (RCBD). Growth parameters assessed fortnightly were plant height (cm), stem diameter (mm) and number of leaves. Soil temperature of each treatment at different time intervals were also monitored and recorded. Data recorded were analyzed using descriptive statistics and analysis of variance (ANOVA). The result showed that T1 had the best performance in terms of plant height and stem diameter while equal number of leaves were recorded in all the treatments. Analysis of variance (ANOVA) showed that there were no significant differences among treatments at 5% level of significance. This indicates that polythene pot thickness of 0.01 mm-0.04 mm can be used to raise C. albidum seedlings at the nursery stage. Soil temperature increases with polythene pot thickness. Hence, T4 gave the highest soil temperature of 36.7 oC. Soil temperature and seedlings growth increases with polythene pots thickness. For optimum growth and development of C. albidum seedlings in the nursery 0.01 mm polythene pot should be used.

AbstractMedicinal plants represent a valuable commodity due to beneficial effects of their natural products on human health, prompting a need for finding a way to optimize/increase their production. In this study, a novel growing media with various perlite particle size and its mixture with peat moss was tested for hydroponic-based production of Echinacea purpurea medicinal plant under greenhouse conditions. The plant growth parameters such as plant height, total fresh leave weight, fresh root weight, total biomass, total chlorophyll, leaf area, and essential oil compositions were assessed. Perlite particle size in the growing media was varied from very coarse (more than 2 mm) to very fine (less than 0.5 mm), and the ratio between perlite and peat moss varied from 50:50 v/v to 30:70 v/v. In addition, two nitrate (NO3−) to ammonium (NH4+) ratios (90:10 and 70:30) were tested for each growing media. The medium containing very fine-grade perlite and 50:50 v/v perlite to peat moss ratio was found to be most optimal and beneficial for E. purpurea performance, resulting in maximal plant height, fresh and dry weight, leaf surface area, and chlorophyll content. It was also found that an increase in NO3−/NH4+ ratio caused a significant increase in plant growth parameters and increase the plant essential oil content. The major terpene hydrocarbons found in extract of E. purpurea with the best growth parameters were germacrene D (51%), myrcene (15%), α-pinene (12%), β-caryophyllene (11%), and 1-Pentadecene (4.4%), respectively. The percentages of these terpene hydrocarbons were increased by increasing of NO3−/NH4+ ratio. It can be concluded that decreasing the perlite particle size and increasing the NO3−/NH4+ ratio increased the plant growth parameters and essential oil compositions in E. purpurea.

Sage and mountain sage belong to Lamiaceae family which have commercial importance from medicinal and aromatic plants in Turkey. The aim of this study was to evaluate the effects of different doses of selenium in salinity conditions on the morphological characteristics of sage (Salvia officinalis L.) and mountain tea (Sideritis sp.). Four different doses of selenium (5, 10, 20, 40 mg/l) were applied in without salinity (0) and salinity (250 mM NaCl/l) medium. The experiment was carried out in the split plot design with three replications in the climate chamber room of the department of field crops. When the examined properties were evaluated; plant height changed between 15.56-23.85 cm, number of branches 10.50-12.78 number/plant, number of leaves 52.78-92.00 number/plant, fresh leaf weight 2.48-7.51 g/plant, dry leaf weight 0.48-3.32 g/plant, fresh root weight 1.52-7.16 g/plant, dry root weight 0.19-1.24 g/plant, root length 26.18-36.07 cm, fresh shoot weight of 1.13-7.15 g/plant and dry shoot weight 0.13-0.38 g/plant. In mountain tea, the properties were determined for plant height as 3.26-5.93 cm, for number of branches as 2.50-6.33 number/plant, for number of leaves as 28.22-91.14 number/plant, for fresh and dry leaf weights as 2.42-11,03 and 0.45-1.91 g/plant, for fresh and dry root weights as 0.71-3.97 and 0.18-0.74 g/plant, for root length as 14.78-33.26 cm, for fresh and dry shoot weights as 0.29-2.28 and 0.12-0.41 g/plant were determined. As a result of this study, 5 mg/l selenium application in salinity conditions in both plants has reached high values in terms of fresh leaf weights. In addition to this, it was found that selenium applications in salinity conditions had positive effects on dry leaf weight in sage and fresh root and fresh shoot weights in mountain tea. As a result of correlation analysis, positive correlations were found between dry leaf weight and other characteristics especially in mountain tea in terms of traits examined in both plants.

PGPR (Plant Growth Promoting Rhizobacteria) is a substance that helps plant growth with the help of rhizosphere microorganisms. PGPR propagation can be done with liquid media. This PGPR propagation needs to be done because this substance has many benefits for agricultural cultivation. The application of PGPR to the test plant, namely the pakcoy plant, proved that there was an effect of giving PGPR to the plant. Observations on the test plants were carried out by observing several observation variables such as plant height, root length, number of leaves, wet weight and dry weight. The results of these observations showed that the effect on the test plants was seen in the variables of root length, wet weight, and dry weight. Meanwhile, the variable plant height and number of leaves did not show a visible difference.

Field trials were carried out during 2018 and during 2019 dry season periods at Federal College of Forestry and Mechanization Afaka Kaduna, located between latitude 10° 35”N and longitude 007° 21”E at altitude 644 m above sea level, to determine the effects of organic manure source and weeding frequencies on growth parameters of jute mallow (Corchorus olitorious). The experimental treatments consists of ten combinations of poultry manure + weed free, cow dung + weed free, goat dropping + weed free, poultry manure + weeding at 2 WAT, cow dung + weeding at 2 WAT, goat dropping + weeding at 2 WAT, poultry manure + weeding at 4 WAT, cow dung + weeding at 4 WAT, goat dropping + weeding at 4 WAT and  no organic manure application + no weeding which were laid out in a randomize complete block design (RCBD) and replicated 3 times The growth parameters observed  and measured were crop vigour score, plant height, shoot diameter, number of leaves and number of  primary branches. Result of the study showed that at harvest (8 WAT) all the treatments significantly affected the vigour of jute mallow crop and gave comparable score than the least observed with no nutrient + no weeding as control. The result revealed that plant growth at harvest exhibited significantly taller plant with application of poultry manure + weeding at 2 WAT. In conclusion the result obtained from the study showed that poultry manure at 4 tons /ha + weeding at 4 WAT resulted in taller plant height, wider shoot diameter, increased number of leaves, number of branches than all other treatment due to lower weed infestation, it is therefore recommended as the best treatment combination to obtained the best growth rate of jute mallow.

Our objective was to investigate the influence of alternative substrates based on stem decomposed by babassu and humic substances in the production of sunflower seedlings. The experimental design was randomized blocks, in a 3 x 4 factorial scheme (substrate x humic substances). Twelve treatments were studied, T1 (100% babassu stem decomposed (BDS) + 0 ml L-1 HS), T2 (100% BDS + 12.5 ml L-1 HS), T3 (100% BDS + 25 ml L-1 HS), T4 (100% DBS + 50 ml L-1 HS), T5 (50% DBS + 50% LAd + 0 ml L-1 HS), T6 (50% DBS + 50% LAd + 12, 5 ml L-1 HS), T7 (50% DBS + 50% LAd + 25 ml L-1 HS), T8 (50% DBS + 50% LAd + 50 ml L-1 HS), T9 (100% LAd + 0 ml L-1 HS), T10 (100% LAd + 12.5 ml L-1 HS), T11 (100% LAd + 25 ml L-1 HS) and T12 (100% LAd + 50 ml L-1 HS). Each treatment was performed in four replications with one seedling per plot, totaling 48 plots. The DBSxHS interaction provided increases in root length, root volume, basal diameter, number of leaves, plant height and parameters related to inflorescence. The substrate with 100% decomposed babassu stem, together with the dose of 12.5% humic substance, is the best option for producing 'IAC Uruguay' sunflower seedlings. Further research on the use of DBS and HS is needed to address the use and purpose in producing new crops.
