The pot experiment was carried out during two successive seasons (2016/2017 & 2017/2018) to study the effect of five levels of salinity and three levels of silicon (Si), as a foliar-spray application as well as their combinations on growth, productivity and chemical constituents of chia (Salvia hispanica L.) plants. Results showed that there was a negative relationship between vegetative growth measurements i.e., plant height, fresh weight and dry weight, flowering growth and yield parameters i.e., main inflorescence height, main inflorescence weight, inflorescences weight, seeds weights, weight of 1000 seeds and calculated seeds yield /m2 and root growth measurements i.e. root length, root weight and root diameter values and salinity treatments in both seasons. Hence, as the concentrations of salinity increased, the values of these parameters decreased to reach the maximum decreasing at the high concentration (4.69 dS m-1). Therefore, the combination treatment between 0.68 dS m-1 salinity concentration and 2000 ppm silicon scored the highest values of these parameters, in the 1st and 2nd seasons. Meanwhile, the maximum values of N, P and K contents were recorded by the combination treatment between 0.68 dS m-1 salinity concentration and 2000 ppm silicon in both seasons. Whereas, the highest values of free proline, sodium and chloride content were gained by the high concentration of salinity 4.96 dS m-1 especially those received silicon at 0 ppm in both seasons. Conclusively, the highest growth, productivity and chemical constituents of chia (Salvia hispanica L.) plant, it is preferable to grow the plants under saline water irrigation concentration at (0.68 dS m-1) and spray with silicon at 2000 ppm.

Set Up

The demand for sources of nutraceuticals has led to the rediscovery and diffusion of traditional crops such as chia (<em>Salvia hispanica</em> L.), whose leaves and fruits are rich in W3 fatty acids and anti-oxidants. Chia originates in Central America but it is rapidly expanding to new areas. A field experiment conducted at Atella in Basilicata (Southern Italy) was set up to test the response of chia to N top-dress fertilisation (0 and 20 kg ha<sup>–1</sup>) and to sowing density (D1=125, D2=25, D3=8 and D4=4 plants m<sup>–2</sup>) in a split-plot design with three replications. First results show maximum leaf area index values up to 7.1 and fresh vegetative biomass production at early flowering ranging between 50.87 (D4) and 59.71 (D1) t ha<sup>–1</sup>. Yield increased with plant density: a significantly (P&lt;0.01) higher production (398 kg ha<sup>–1</sup>) was reached in D1. N top-dressing had a detrimental effect on yield and corresponded to higher lodging and lower maturation percentage of seeds, though non-significant. Based on our first results it seems worthwhile to continue agronomical trials for chia in herbaceous systems of southern Italy for leaf production based on traditional genotypes, while fruit production might be pursued by adopting high sowing density and the search for longer-day genotypes.

Aim. Preparation of aseptic seedlings Salvia hispanica L., callus initiation in vitro and establishment of primary explants suitable for the callus production. Methods. Seeds are sprouted on our own modification of conventional methods. The non-hormonal Murashige-Skoog agarized nutrient medium was used as basic medium for the experiments. Parts of one-month seedlings (roots, hypocotyl, cotyledon leaves) were used as explants for the use of the colza. We added growth regulators (BAP, 2,4-D) in different concentration combinations into the nutrient medium for callus initiation. Statistical processing was performed in Microsoft Office Excel. Results. Aseptic S. hispanica seedlings have been obtained. The callus growth was initiated on all types of explants, the dependence of the callus intensity on the type of explants and the growth regulators content in the nutrient medium was established. Morphogenic callus and root-regenerants have been obtained. Conclusions. Hypocotyl was the most suitable primary explant for callus growth. Seedlings, leaves and roots showed low morphogenetic capacity. The nutrient medium with an elevated 2,4-D content was the most effective for initiation of callus genesis and proliferation of non-morphogenous callus. A high concentration of 2,4-D in the medium improves S. hispanica callus growth but suppresses its morphogenic ability.Keywords: Salvia hispanica (Chia), in vitro culture, callus.

Chia (Salvia hispanica L.) contains the highest level of omega- 3 fatty acid available in any cultivated plant source. The objective of this research was to find out the suitable planting time for chia in Bangladesh and to study the effect of planting time on its growth and yield. An experiment was carried out at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University (BAU), Mymensingh, during the period from November 2013 to July 2014 to study the growth, morpho-physiological yield contributing characters and yield of chia. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The collected data were analyzed statistically and the means were adjudged by DMRT using the statistical computer package program, MSTAT_C. The tallest plant (136 cm), highest number of inflorescence plant–1 (13.67), highest amount of total dry matter (305 g) and highest root length (7.767 cm) were recorded from November planting at harvest. However, leaf area plant–1 (207.2 cm2) and LAI (1.891) had also significantly higher from November planting at 90 days after sowing (DAS) compared to other planting times. November planting further recorded the higher CGR (33.43 g m-2 day-1) at the stage between 76–90 DAS and thereafter they decreased. Higher seed yield (1033 Kg ha–1), husk yield (888 Kg ha–1), seed yield plant-1 (4.773 g), husk yield plant-1 (2.840 g) were also recorded from November planting. In December planting the seed yield, husk yield, seed yield plant-1, husk yield plant-1 were 681 Kg ha–1, 340 Kg ha–1, 2.350g and 0.9467g, respectively. Lower seed yield (159 Kg ha–1), husk yield (166 Kg ha–1), seed yield plant-1 (0.6150 g) and husk yield plant-1 (0.5383 g) were recorded from January planting. Except total dry matter, other morpho-physiological characters, yield and yield contributing factors were less effective in January than other planting time. February and March planting did not produce any fertile spike resulting yield less vegetative growth. These results revealed that, November planting was found outstanding superiority for plant growth, yield and morpho-physiological characters of chia in Bangladesh.Asian J. Med. Biol. Res.

Corn (Zea mays L.) is an important crop in Brazil and is cultivated in all regions, including the semi-arid area of Brazil, where the occurrence of irrigation water with high concentration of salts is common. Evaluating the growth and yield of the maize hybrid 'AG 6690' irrigated with water of different salinity levels was the objective of this experiment. Sowing was performed in pots with 12 seeds on May 23, 2003, and seedlings were thinned to two plants per pot. Irrigation was accomplished when the mean soil matric potential of each treatment was approximately -30 kPa using water with seven different electrical conductivities (ECi), varying from 0.3 to 4.5 dS m-1, which were obtained by addition of NaCl and CaCl2 in the equivalent proportion of 1:1. The dry weights of all parts of the corn plants as well as their evapotranspiration and water use efficiency were reduced by salinity. Grain yield decreased by 21 and 20% for each unit increase of ECi and electrical conductivity of soil solution (ECs) above the respective threshold values of 1.7 and 4.3 dS m-1, respectivelly. Plants were able to maintain the leaf area index unaltered under moderate saline conditions.

Variations in the protein, lipid and fatty acid content of the commercial chia seed (Salvia hispánica L.) produced in Ecuador Resumen El objetivo fue determinar las variaciones en los contenidos de proteína, lípidos y composición de ácidos grasos de las semillas de chía producidas comercialmente en seis sitios de los ecosistemas de los Valles Interandinos (Altos y Bajos), Selva Lluviosa Pluviestacional y Bosque Seco Tropical, del Ecuador. El contenido de proteína fue más alto (p<0,05) en las semillas de Bosque de Oro (24,78%) y El Azúcar (24,35%) que las de los otros cuatro sitios, y sin diferencias significativas (P<0,05) entre ellos. Las semillas de Bosque de Oro (34,90%) y San Pablo presentaron el más alto contenido de lípidos, aunque sin diferencias significativas (p<0,05) con las de Salinas (32,65%) y Patate (31.97%). Las semillas originadas en Salinas presentaron el mayor (p<0,05) contenido de α-linolénico (66,75%), seguido por las de Patate (63,93%), Guayllabamba (63,57%), Bosque de Oro (63,53%) y San Pablo (62,70%). El ácido graso α-linolénico presentó una alta relación negativa con los ácidos grasos palmítico (R2 = 0,797; p<0,001), linoleico (R2 = 0,862; p<0,001), y oleico (R2 = 0,767; p<0,001). Palabras clave: aceite; ácidos grasos; chía; Ecuador; Salvia hispánica L. Abstract The objective was to determine the variations in the protein content, lipids and fatty acids composition of the chia seeds commercially produced in six locations of the Inter-Andean Valley (Low and high), Rainforest and Tropical Dry Forest ecosystems of Ecuador. The protein content was higher (p< 0.05) in the seeds from Bosque de Oro (24.78%) and El Azúcar (24.35%) than those originated in the other four locations and without significant differences (p < 0.05) between them. The seeds of Bosque de Oro (34.90%) and San Pablo had the highest lipid content, although without significant differences (p<0.05) with those of Salinas (32.65%) and Patate (31.97%). The seeds originated in Salinas had the highest (p<0.05) content of α-linolenic (66.75%), followed by those of Patate (63.93%), Guayllabamba (63.57%), Bosque de Oro (63.53%) and San Pablo (62.70%). The α-linolenic fatty acid showed a high negative relationship with palmitic fatty acids (R2 = 0.797; p<0,001), linoleic (R2 = 0.862; p<0.001), and oleic (R2 = 0.767; p<0.001).

Pots experiment were carried out in green house of National Research Centre, Dokki, Egypt, to study the effect of potassium and humic acid application to minimize the adversely effects of soil salinity on pea plants. Pots were divided into three main groups of soil salinity at levels (2.84, 6.03 and 8.97 dS m-1). These main groups were applied potassium sulfate at the rates 50 and 100 kg fed-1. Foliar application of humic acid was applied at a rate of 0.2%. Data presented that the application of K2SO4 at a rate of 100 kg fed-1 with humic acid a foliar spray at a rate of 0.2%, gave the highest values of plant growth parameters such as, Branch No., Leave No., Plant height, leaf area, Shoot fresh and dry weight. In addition to produce high chlorophyll a and b and carotene content as compared to other treatments and control under the different soil salinity levels. Application of K2SO4 (100 kg fed-1) with foliar spray of humic acid under high and moderate soil salinity condition increased pod weight, seed weight, seed dry weight over application of 50 kg   fed-1 and control. The highest values of studied chemical constituents in shoots and greens were obtained due to the application of potassium sulfate at100 kg fed-1 with humic acid. The combined effects of potassium application and foliar spray of humic acid had a positive effect on increasing the ability of pea plant tolerance to soil salinity and increasing of growth and yield production under saline soil conditions.
