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.

Moringa Oleifera Lam

<p>A moringa (<em>Moringa oleifera</em> Lam) é uma árvore nativa da Índia e de elevada importância principalmente pelo seu valor nutricional, medicinal e de purificação da água. Este trabalho teve como objetivo avaliar o efeito de níveis de fertilização orgânica no crescimento e desenvolvimento inicial de mudas de moringa nas condições semiáridas do Estado da Paraíba, Brasil. O experimento foi conduzido em condições de túnel plástico, localizado no Centro de Ciências e Tecnologia Agroalimentar, da Universidade Federal de Campina Grande, Campus de Pombal, UFCG. Utilizou-se o delineamento inteiramente casualizado, com os tratamentos compostos de sete níveis de fertilização orgânica (0,0; 108,0; 216,0; 432,0; 864,0; 1728,0 e 3456,0 g.vaso<sup>-1</sup>), com quatro repetições. Foram avaliados os seguintes parâmetros: i) altura das plantas (cm), ii) diâmetro do caule (mm), iii) número de folhas, iv) fitomassa fresca das folhas, v) fiomassa seca da parte aérea (g), vi) fitomassa seca da raiz (g), vii) razão fitomassa seca da parte aérea/raiz (g) e, viii) comprimento da raiz principal (cm). A utilização dos níveis de fertilização orgânica influenciou significativamente o crescimento e desenvolvimento inicial das mudas de moringa. Com a elevação dos níveis de esterco adicionados ao substrato, observou-se o decréscimo das variáveis analisadas, tendo como melhor resultado o nível de 864,0 g.vaso<sup>-1</sup> para a altura da planta e o nível de 432,0 g.vaso<sup>-1</sup> para os demais parâmetros avaliados. O nível de 432,0 g.vaso<sup>-1</sup> provocou os maiores acréscimos na massa seca da parte aérea e comprimento das raízes. Os níveis de esterco bovino de 108,0 g.vaso<sup>-1</sup> e 432,0 g.vaso<sup>-1</sup>, promoveram um maior incremento para a razão entre a parte aérea/raiz e comprimento da raiz, respectivamente. Para produção de mudas de moringa de boa qualidade a aplicação de pequenas quantidades de esterco bovino é suficiente.</p><p align="center"><strong><em>O</em></strong><strong><em>rganic fertilization levels on the vegetative growth of moringa (</em></strong><em>Moringa oleifera<strong> Lam.)</strong></em><strong><em></em></strong></p><p><strong>Abstract</strong><strong>: </strong>Moringa (Moringa oleifera Lam) is a tree native of India and high importance especially for its nutritional value, medicinal and water purification. This work aimed to evaluate the effect of organic fertilization levels on growth and initial development of moringa seedlings in semi-arid conditions of the State of Paraiba, Brazil. The experiment was conducted in plastic tunnel conditions, located in the Centro de Ciências e tecnologia Agroalimentar da Universidade Federal de Campina Grande, Campus de Pombal, UFCG. We used a completely randomized design with the treatments composed of seven levels of organic fertilization (0,0; 108,0; 216,0; 432,0; 864,0; 1728,0 e 3456,0 g.vaso<sup>-1</sup>), with four repetitions. The following parameters were evaluated: i) plant height (cm), ii) stem diameter (mm), iii) number of leaves, iv) fresh weight of leaves, v) dry weight of shoots (g), vi) dry weight of the root (g), vii) dry weight ratio of shoot / root (g) and viii) main root length (cm). The use of organic fertilization levels significantly influenced the growth and early development of moringa seedlings. With the rise of manure levels added to the substrate, there was the decrease of the variables analyzed, with a best result the level of 864.0 g.vaso<sup>-1</sup> for plant height and the level of 432.0 g.vaso<sup>-1</sup> for the other parameters. The level of 432.0 g.vaso<sup>-1</sup> caused the greatest increases in dry weight of shoot and root length. The levels of bovine manure 108.0 g.vaso<sup>-1</sup> and 432.0 g.vaso<sup>-1</sup>, promoted a greater increase for the ratio of root / shoot and root length, respectively. To produce good quality moringa seedlings the application of small amounts of bovine manure is sufficient.</p>

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.
