The germination response of Lycopersicon esculentum was studied on different salinity levels from control (non-saline), 0.2,0.4,0.6 and 0.8% NaCl solution. Seeds germinating under salt stress exhibited decrease in saline media as compared to respective control. Seeds germinating with salinity and brassinosteroid (applied exogenously through roots and as foliar spray, 0.25 and 0.5 ppm) exhibited promotion in control as compared to their respective saline media. Plants treated with different salts concentrations (60 and 100mM) NaCl exhibited reduction in plant height, root length, number of leaves, number of fruits and biomass as compared to control while brassinosteroid having concentrations of 0.25 and 0.5 ppm (applied through roots and as foliar spray) caused promotion in plant height, root length, number of leaves, number of fruits and biomass in saline and non saline media. Plants treated with different salts concentration of (60 and 100mM) NaCl exhibited increase in Relative water content, leaf water loss, electrolyte leakage, shoot/- root ratio, root/- weight ratio and leaf/- weight ratio at both NaCl concentrations (60 and 100 mM) as compared to control, while stem/- weight ratio showed reduction at both salinity levels as compared to control while brassinosteroid applied in roots and as a foliar spray at 0.25 and 0.5 ppm concentrations exhibited reduction in stem/- weight ratio at high NaCl level (100 mM) as compared to control.

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.


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.

Tomato is an important horticultural commodity in Indonesia and plays strategic role in fulfilling daily needs of the public. The increase in production of tomato can be done by optimizing the provision of nutrients that support growth. The ability of bacteria as biological fertilizer to dissolve phosphate and produce IAA (Indole Acetic Acid) are important criteria for the use of bacteria as agents of plant growth promoters. The purpose of this study was to determine the ability of some isolates of Bacillus subtilis and Pseudomonas fluorescens in dissolving phosphate and produce IAA to enhance the growth of tomato. Phosphate test results showed that all isolates of B. subtilis and P. fluorescens capable of dissolving phosphate with the highest value indicated by P. fluorescens UB-PF5 (18 mm). All isolates of bacteria capable to produce IAA. The resulting value IAA ranged from 0.69 to 1.09 ppm with the highest value produced by B. subtilis UB-ABS2 (1.09 ppm). The test results on the parameters of root weight, root length, plant height and number of leaves showed that tomato treated with B. subtilis and P. fluorescens increased significant growth compared with watering only with distilled water. The highest increased root weight and root length were resulted by P. fluorescens UB-PF5 with values 97.10% and 64.83%, respectively. The highest increased plant height and number of leaves length were resulted by P. fluorescens UB-PF6 with values 38,80% and 30,7%, respectively.

Salinity is one of the limiting environmental factors for crop production. Chickpea has special importance among the legumes especially in arid and semi-arid regions and is sensitive to salinity. Therefore, it becomes necessary to make a plan to mitigate the salinity effect on this plant. For this purpose, an experiment was conducted in the net house of Department of Botany, Kurukshetra University, Kurukshetra to investigate the role of sulfosalicylic acid (SSA) at different concentrations (10-4, 10-5 and 10-6 M) in overcoming salinity stress imposed on chickpea plants in natural conditions. Different salinity levels (0, 50 mM, 100 mM and 150 mM) were applied and caused a significant reduction in morphological and yield parameters. Our main findings are as follows: (1) Salt stress has detrimental effects on growth and physiology of plants. (2) Application of SSA at 10-5 M was the most significant concentration in modulating the inhibitory effects of salt stress.

Saline irrigation water is becoming an important water source as fresh water is fast becoming a scarce resource in many areas of the world, including Eswatini, especially in arid and semi-arid regions.  A study to test the response of two varieties of spinach (fordhook giant and mustard) to salinity was conducted in a field pot experiment at the Faculty of Agriculture at the Luyengo Campus of the University of Eswatini.  The treatments were laid in a randomized block design (RCBD).  The experiment consisted of four treatments, each replicated twelve times.  Treatments were salinity levels of 0.0 dS/m, 1.5 dS/m, 2.0 dS/m and 3.5 dS/m.  All the treatments were subjected to similar agronomic practices. Spinach was grown and observed for a period of five weeks.  Plant height was measured and the number of leaves counted weekly throughout the experiment. Significant differences (P < 0.05) between salinity treatments were obtained for plant height beginning in week 2 but were more pronounced in week 3, 4 and week 5.  No significant differences were obtained for the number of leaves.  There were however, clear significant differences between spinach irrigated with none saline irrigation water compared to saline irrigation water.   It was concluded that irrigating spinach with saline water of more than 2.0 dS/m drastically reduce plant growth but not the number of leaves under the conditions of the experiment.

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.
