Basil (Ocimum basilicum L.) is a medicinal species of Lamiaceae family, popularly known for its multiple benefits and high levels of volatile compounds. The species is considered to be one of the most essential oil producing plants. Also cultivated in Brazil as a condiment plant in home gardens. The objective of this study was to evaluate the effect of salinity on the growth of basil in nutrient solution of Furlani and to identify variables related to the salinity tolerance in this species. The first assay was performed with variation of five saline levels (0 - control, 20, 40, 60 and 80 mM NaCl). In the second assay six genotypes were evaluated in two salinity levels 0 and 80 mM NaCl. The height, stem diameter, number of leaves, dry mass and inorganic solutes in different organs, photosynthetic pigments, absolute membrane integrity and relative water content were evaluated. All biometric variables in basil were significantly reduced by salinity. Dry matter yield and percentage of membrane integrity were the variables that best discriminated the characteristics of salinity tolerance among the studied basil genotypes. Basil genotypes showed a differentiated tolerance among the genotypes, the ‘Toscano folha de alface’ being considered as the most tolerant and ‘Gennaro de menta’ as the most sensitive, among the species studied.

Pitombeira is a native fruit tree from Amazon and is exploited in an extractive way. Currently, there is no commercial cultivation of this crop since there are no technologies for cultivation, propagation methods, fertilization and irrigation. In this context, the aim of this study was to evaluate growth and dry matter of pitombeira seedlings (Talisia esculenta (A. St.-Hill.) Radlk.) under salinity levels with or without bovine biofertilizer. The experiment was performed in a nursery at the State University of Paraíba (UEPB), Campus IV, in Catolé do Rocha, Paraíba, from September to December 2015. It was adopted a completely randomized design (CRD) with 10 treatments and 4 repetitions, in factorial arrangement 5 x 2, corresponding to 5 salinity levels: (0,8; 2; 4; 6 e 8 dS m-1) with or without bovine biofertilization. Plant height, stem diameter, number of leaves, leaf area, total leaf area, Dickson quality index, dry mass of root, stem, leaf and the whole plant were analyzed. The increase in salinity provides a decrease in growth and dry matter of pitombeira seedlings. The use of biofertilizers mitigates the harmful effects of salinity on pitombeira seedlings.

A study was conducted in the Department of Agronomy, Bangladesh Agricultural University (BAU), Mymensingh from April to August 2012 to examine the salinity tolerance of eight jute varieties (CVE-3, C-83, CVL-1, BJC-7370, O-795, O-9897, OM-1, O-72) and two kenaf varieties (HC-95 and HC-2). Initially germination of these varieties were evaluated under six salinity levels viz. 0mM, 20mM, 40mM, 60mM, 80mM, and 100mM NaCl in the seed laboratory of the Department of Agronomy. Afterwards, all the varieties was grown in pots in the net house under four salinity levels viz. 0mM, 25mM, 50mM, and 75mM. The results from the germination study revealed that under control condition (0mM NaCl) all the jute varieties showed germination more than 80% both at 7 and at 14 days after seed sowing, whereas kenaf varieties had germination a little less than 80%. Among the jute varieties, O-72 showed the highest germination (92%), which was statistically similar with those of OM-1(91%), O-795 (90%), and C-83(87%). Salinity stress decreased germination drastically in all of the jute and kenaf varieties. A salinity level of 100mM caused the highest germination inhibition (74.70%) in jute variety CVL-1, which was very close to those of BJC-7370 and O-72. On the other hand, the lowest germination inhibition (51.11%) was recorded in jute variety O-795. The results of the pot trail showed that the plant characters of jute and kenaf varieties were affected significantly by salinity stress. All the varieties produced their respective plant height, number of leaves per plant, and plant dry weight under control condition (no salinity). Among these varieties, CVE-3 produced the highest plant height (145.2cm), and total dry weight (22.55g), whereas O-72 produced the highest number of leaves per plant (24.67). All these plant characters decreased sharply due to salinity stress irrespective of variety. However, the rate of decrease of plant characters occurred differentially in the jute and kenaf varieties. The highest rate of decrease in number of leaves (74.22%) was found from the variety CVE-3, whereas the lowest one was recorded from the variety HC-2 (51.68%). Salinity stress caused the highest decrease in total plant dry weight (73.68%) in the variety CVL-1 and plant height (73.64%) also in the variety CVL-1. On the contrary, the lowest decrease in plant dry weight (50.99%) was found in the variety O-9897 and plant height also in variety O-9897 (50.88%). Based on the results from germination test and pot trail, it can be inferred that jute variety O-9897 appeared to be the most salt tolerant followed by O-795, HC-2, HC-95, CVE-3, O-72, C-83, BJC-7370, OM-1, and CVL-1.

Lettuce plants, cv. Vera, were grown under five salinity levels in a hydroponical experimental set-up using a 0.15 m deep sand growing bed. A standard nutrient solution was used, with the following composition, in mmol L-1: 16.9 NO3-; 2.0 H2PO4-; 1.0 SO4- 4.0 Ca++; 10.9 K+ e 1.0 Mg++, and, in mg L-1, 0.42 Mn; 0.26 Zn; 0,05 Cu; 0,50 B; 0,04 Mo, and 4.82 chelated Fe. The five salinity levels compared as treatments were obtained by varying the concentration of the standard nutrient solution, reaching average electrical conductivities (EC) of 0.80; 1.93; 2.81; 3.73 and 4.72 dS m-1, for T1, T2, T3, T4 and T5, respectively. The nutrient solution at each salinity level was supplied from a reservoir by means of a flooded-type electrical pump, for 15 minutes, at intervals of 90 minutes during the day and 420 minutes during the night. A completely randomised experimental design was used with four replications and 20 plants per plot. Four plants of each plot were harvested at 32 days after planting, to determine shoot and root dry mass, shoot fresh weight, leaf area and number of leaves per plant. Number of leaves was 18 per plant and was not affected by treatments. Dry mass of leaves increased 24,4% from T1 to T3. No relationships were found on data from stem and root dry mass. A positive effect of EC was recorded on shoot fresh mass, which increased 28.5% from T1 to T2, and decreased 16.5% from T2 to T5. Maximum LAI estimated value was 4.3 m² m-2 for an EC of 2.6 dS m-1. Salinity levels above 2.0 and 2.6 dS m-1 reduce fresh yield and plant growth, respectively.

AMBIENTES DE LUZ E DOSES DE FÓSFORO NO CRESCIMENTO DE PLANTAS DE MANJERICÃO O objetivo do trabalho foi avaliar o desenvolvimento das plantas de manjericão cultivadas em ambientes de luz modificada com o uso de malhas fotoconversoras sob diferentes dosagens de adubação fosfata. O delineamento experimental foi em blocos ao acaso em esquema fatorial 4 x 3, sendo os tratamentos: 0;50; 100 e 200 kg ha-1 de P2O5, e três ambientes de luz utilizando malhas fotoconversoras nas cores : azul e vermelho com 50% de sombreamento e a pleno sol, com cinco repetições. Após 120 dias de cultivo foram realizadas análises de crescimento das plantas de manjericão, além do teor de fósforo nas raízes. Observou-se interação significativa entre as doses de fósforo e os ambientes de luz para as variáveis número de folhas, área foliar, área foliar especifica, razão de área foliar e razão de peso foliar. Plantas de manjericão cultivadas a pleno sol na dosagem máxima de fósforo (200 kg ha-1 P2O5) apresentaram resultados significativamente superiores em relação àquelas cultivadas sob sombreamento. Porém vale ressaltar que o ambiente sombreado proporcionou maior altura e produção de massa seca, além de maiores teores de fósforo nas raízes. Conclui-se que a interação das malhas fotoconversoras com a adubação fosfatada apresentou resultados positivos em relação ao desenvolvimento das plantas de manjericão.Palavras-chave: luminosidade, planta medicinal, sombreamento, ocimum basilicum L. ABSTRACT:The objective of this work was to evaluate the development of basil plants cultivated in modified light environments with the use of color shading nets under different dosages of phosphate fertilization. The experimental design was a randomized block factorial design 4 x 3, with the treatments: 0, 50; 100 and 200 kg ha-1 P2O5 using shading nets in colors: blue and red, with 50% shading and full sun, and five replications. After 120 days of cultivation, analyzes of the growth of basil plants were carried out, in addition to the phosphorus content in the roots. There was a significant interaction between phosphorus doses and light environments for the number of leaves, leaf area, specific leaf area, leaf area ratio and leaf weight ratio. Basil plants grown in full sun at the maximum phosphorus dosage (200 kg ha-1 P2O5) showed significantly higher results than those grown under shade. However, it is worth noting that the shaded environment provided higher height and dry mass production, in addition to higher phosphorus levels in the roots. It was concluded that the interaction of color shading nets with the phosphate fertilization presented positive results in relation to the development of the basil plants.Keywords: luminosity, medicinal plant, shading, Ocimum basilicum L.

Arugula is a crop of fast vegetative growth and short cycle, widely accepted worldwide. In Brazil, its production generates jobs and income for family farming. However, the use of saline water in the cultivation of this plant is one of the main factors that limit production. Given this situation, the objective of this study was to evaluate the growth of Apreciatta arugula cultivated under conditions of shading and salinity levels of irrigation water. The experiment was conducted in a greenhouse in the experimental area of the Agricultural Sciences Center of the Federal University of Alagoas, in the city of Rio Largo, AL. The treatments were obtained from the combination of two shading conditions (with shading and without shading) and five levels of electrical conductivity of the irrigation water (0.5; 2.0; 3.5; 5.0 and 6.5 dS m-1). The experimental design used was completely randomized in a 2 x 5 factorial scheme. Combined, the factors resulted in 10 treatments with four replications and one plant per plot, totaling 40 experimental units. Arugula plants were evaluated for leaf number, plant height, leaf area and dry matter of the aerial part. Increasing levels of salinity in the irrigation water, lead to a reduction in the number of leaves, plant height and dry mass of the aerial part of arugula plants cultivar Apreciatta. However, the use of shading together with the salinity of irrigation water up to 1.4 dS m-1does not affect the leaf area of arugula plants, being possible to cultivate without considerable losses.

The Impact

Introduction. Common basil (Ocimum basilicum L.) is one of the most valued and widely used spice plants. The highly valued raw material requires properly prepared soil, mainly rich in nutritions. Traditional use of single-component fertilizers, such as nitrochalk, superphosphate and potassium salt does not guarantee its uniform sowing in the field. The multi-component fertilizer is a safer option. Aim. The investigation was performer in order to assess the impact of multi-component fertilizers on the size and some quality features of the yield of common basil in experimental nutrient works. Material and methods. Three experimental nutrient works were performed in 2013-2015 in the cold greenhouse of the Institute of Natural Fibres and Medicinal Plants (Plewiska, Poland) with use of common basil cvar. ”Wala” seedlings. Fresh and dry mass of herb (after drying in a thermal dryer to a constant weight) and the content of essential oil (by steam distillation in the Deryng apparatus). The outcomes were statistically analyzed (analysis of variance). Results. The increase in dry matter of herb was noted with use of Salmag S fertilizer, as compared to the combination with traditional one-component fertilizers, regardless of the level of fertilization. The content of essential oil in the raw material did not depend on the type and size of the fertilizer used. Conclusions. The research results justify the use of specific multicomponent fertilizers in the cultivation of basil and will be implemented into practice (training, consulting) as a part of the introduction of rational fertilization principles.

The demand for salinity-tolerant turfgrasses is increasing due to augmented use of effluent or low-quality water (sea water) for turf irrigation and the growing turfgrass industry in coastal areas. Experimental plants, grown in plastic pots filled with a mixture of river sand andKOSASRpeat (9 : 1), were irrigated with sea water at different dilutions imparting salinity levels of 0, 8, 16, 24, 32, 40, or 48 dS m-1. Salinity tolerance was evaluated on the basis of leaf firing, shoot and root growth reduction, proline content, and relative water content.Paspalum vaginatumwas found to be most salt tolerant followed byZoysia japonicaandZoysia matrella, whileDigitaria didactyla,Cynodon dactylon“Tifdwarf,” andCynodon dactylon“Satiri” were moderately tolerant. The results indicate the importance of turfgrass varietal selection for saline environments.

The effects of 0, 30 and 60 mM NaCl and substrates (red peat, sand or 3:1:1 [w/w] mixture of peat, sand, or soil) on vegetative growth of lulo, an Andean fruit species, during 12 weeks were studied. The experiment was carried out by using 2000 cm³ of polypropylene plastic pots under greenhouse conditions. Plant height, number of leaves and nodes, leaf area, total plant dry matter (DM), and shoot/root ratio were evaluated. With the increase of salt concentration, the plant height, the number of leaves and nodes, the leaf areas and plant dry mass DM decreased, whereas shoot/root ratio increased. Sand grown lulo plants were most affected by salinity and presented total mortality at 60 mM NaCl. On the other hand, plants held either in peat or in substrate mixture developed larger height, greater leaf and node numbers, higher leaf area and dry matter content. Shoot/root ratio in control (soil) and sand-grown plants (30 mM NaCl) was lower.

The objective of this study was to evaluate the development of corn crop at different levels of irrigation water salinity in two concentrations of soil organic matter. The experiment was conducted at the Center for Agrarian Sciences of the Federal University of Alagoas. The experimental design adopted was the entirely randomized in factorial scheme 5 x 2, with four replications. The treatments consisted of different levels of electrical conductivity of CEa water (0,5; 1,5; 3,0; 4,5 and 6,0 dS m-¹) associated with the presence and absence of organic matter in the soil. The saline solutions were prepared with NaCl and distilled water, using the formula: TSD (g L-1) = 0.64 x CEa. At 40 days after emergence, the plants were collected and analyzed for the number of leaves, plant height, leaf area, shoot dry mass and dry mass of the root system and the relative chlorophyll index of the leaves. It was found that all the variables studied were affected by the increase in salinity levels of irrigation water and that the addition of organic matter in the soil in isolation provided a better development of maize plants.

ABSTRACT The capacity of a weed to adapt to the restriction of growth factors is directly related to its ability to compete for those resources with the cultivated species. An experiment was conducted to evaluate the effect of water restriction on the growth and biomass partitioning of four species of weeds. The experimental design used randomized blocks, with five replications. The treatments were arranged in a 4 x 2 factorial, with the first factor being the weed species (Waltheria indica, Crotalaria retusa, Cleome affinis and Commelina benghalensis) and the second, two water regimes: daily irrigation (Irr) and water restriction (WR). The number of leaves, leaf area, dry mass of the plant and its parts (root, stem and leaf), and the mass distribution among different organs (roots, leaves and stems) were determined. The water deficit in the soil increased the root dry matter for C. retusa, W. indica and C. benghalensis, however, it did not alter the mass of the stem of the weeds. C. retusa and W. indica suffered a reduction on the number of leaves, leaf area, dry matter of the leaves and the plant dry matter under water deficit. W. indica and C. retusa had a reduction on the percentage of biomass allocated to the leaves, and an increment on the percentage of the roots mass, while C. benghalensis and C. affinis had an increase only on the roots mass.
