Abstract

Salinity indeed is a great barrier for crop production. An experiment was carried growth, yield and nutrient performance of a salinity tolerant sunflower cultivar on soils with different salinity levels. Salinity's impact on seed germination and vigour exponent were studied. Pot experiment was done with sunflower on different salinity levels (0.55; 2.80; 3.55; 5.05; 6.95; 8.35; and 11.25 dSm-1) were created by using NaCl following CRD with 3 replications. Diverse agronomic parameters and chemical parameters were analyzed. The highest plant height (146.0±3.2 cm) was observed at 0.55 dSm-1 and the lowest (80.3±4.8 cm) was observed in 11.25 dSm-1. The greatest amount of seeds pot-1(300.0 ± 4.619) was observed in 3.55 dSm-1 and least number of seeds pot-1 (170.0 ± 2.887) was recorded in 11.25 dSm-1. The most seed yield (19.80 ± 0.1299 t ha-1) was recorded in 3.55 dSm-1 and the least (6.3 ± 0.1299 t ha-1) in 11.25 dSm-1 soil salinity level. The superior K content in shoot (2.540 ± 0.02309%) was observed in 0.55 dSm-1 and the inferior K contents (1.190± 0.005774%) was recorded in 11.25 dSm-1. The maximum Na contents (2.960 ± 0.03464 %) was observed in 11.25 dSm-1 and the minimum Na contents (0.5800 ± 0.01155%) was observed in 0.55 dSm-1 soil salinity level. The effects of salinity on all agronomic parameters were significant. All the chemical parameters show statistically significant on different salinity levels. The seed yield of sunflower growing on different salinity levels can be produced considerable seed yield up to 8.35 dSm-1.

1. Introduction
In Bangladesh, sunflower is a relatively latterly exhibited crop for oil seed . Because it’s substantial amount of polyunsaturated fatty acids and 0 cholesterol. Sunflowers are grown all throughout the world and are particularly popular in regions with salty soils such as India and China. Sodium chloride salinity has harmed a huge percentage of Bangladesh's coastal area and southern areas . During the Rabi season, when cropland is left fallow, this spot could be seeded with the salinity tolerant species. That would be useful for both our nation and our farmers if any sunflower cultivars were released as salinity resistant is vital to enhance manufacturing oil seeds in our nation to be able to alleviate the oil seed issue shortages.
The rapid growth of the people on the planet and large proportion of agricultural grains are grown on low-quality soils that are sometimes salinized The salinity of soil is rising problem around the globe, and it drastically decreases agricultural productivity, in particular in areas where irrigating is necessary . In dry and arid parts of globe, salt stress presents a severe risk to agricultural productivity due to scarcity of rain and inadequate water and soil control approaches. . Global agriculture output is severely affected by high soil and irrigation water salinity (sodium chloride) . Just 10% of Bangladesh is lower than one meter beneath average sea level, and marine departures affect one-third of the country .
Photosynthesis is the main driver that determines growth of plants and output. It is evident that stomata and non-stomata duties are restricted in salt stress, leading to decreased transpiration, net CO2 absorption, and water consumption performance . The beginning of germination is signaled by elements encircling the embryo by the radicle appearing. The primary elements for salt stress are branch and root width since roots are situated directly contact the earth and draw moisture from it, while shoots distribute it to the remaining plant parts. Thus, the reaction of a plant to salt stress can be inferred a great deal from the length of its roots and shoots . High salt levels can prevent root and shoot expansion because it reduces the plant's capacity for utilizing water . Abnormal saplings can arise from metabolic and molecular issues caused by salt hatred, which can hinder or postpone germination. The consequences of salinity on plants include osmotic impacts, specific-ion toxicities, and dietary dysfunctions. . It not only affects the morphology of plants but also alters their metabolisms by inhibiting their growth.
2. Resources and Techniques
2.1. Trial Location and Material
The trial was carried out at the Postgraduate laboratories and the net home of the Department of Agricultural Chemistry at BAU, during the period July 2023 to June 2024. The test crop under investigation was used for assessing the salinity-tolerance of a sunflower cultivar. The Sunflower (cv. BARI Surjamukhi 2) seeds were collected from (BARI), Gazipur
2.2. Investigational and Pilot Approaches Techniques
The following nine salinity levels were established by adding different dosages of sodium chloride to soils to evaluate the growth performance of salt-tolerant and moderately plants that can withstand salt on soils with diverse salinity equality. For each treatment, three replications were employed. The study was conducted with a completely random design (CRD). There are 7 treatment with expected salinity levels (dSm-1) such as; T0 =0 (control), T2 = 2 (dSm-1), T2 = 2 (dSm-1), T4 = 4 (dSm-1), T6 =6 (dSm-1), T8 = 8 (dSm-1), T10 = 10 (dSm-1), T12 = 12 (dSm-1).
2.3. Collection of Data
Data collection was recorded germination percentage, vigor index, plant height (cm), root length (cm), shoot length (cm), fresh weight (g), dry weight (g), stem diameter (cm), diameter of pod (cm), number of seeds pod-1 and 1000 seeds weight (g) were measured . To calculate the dry mass (g) produced, the final weights of the root and stem were recorded. With the use of the proper screens and a flame release spectrophotometer (Jenway PEP-7), the amounts of sodium and potassium in each specimen were separated. Calcium and magnesium content was determined by the complicated metric titration technique with completing agent Na2-EDTA . Finally, the concentration of sulphur for an unknown test solution was calculated from the standard curve .
2.4. Analytical Statistics
Statistics were used to analyze the data. The three replicates' means ± standard error of the mean (SEM) were used to convey the findings. To ascertain the degree of significance, a t-test was employed, and using MSTAT-C computer package program in various characters was used to fit the graph.
3. Results and Discussions
3.1. Effect of Salinity on Seed Germination of Sunflower
The result shows the increment of seed germination percentage of sunflower with the days after seed sowing nonetheless, there was little variation in the germination % of sunflower at varying salt levels (Figures 1, 2). Moreover, the highest germination percentage (90%) was observed at lowest salinity treatment 0 dSm-1 and the lowest germination percentage (63.33%) was observed at the utmost salinity treatment 20 dSm-1. However, a reduction in sunflower seed germination was observed at 16 dSm-1 and 20 dSm-1 salinity level also found that Hysun-33 attained maximum germination at a salinity index of 1.15 dSm-1 for the whole of the period of testing, with the exception of the 30th day of germination, or from the 10th day (100%) to the 25th day (97%) of germination.

3.2. Impact of Salinity on Seedlings Vigor Exponent of Sunflower
The indicator of seedling vigor statistically significant variation was observed. In major findings from a Tukey's one-way ANOVA multiple comparisons test decline of seedlings vigour index in elevated soil salinity equality in comparison with control treatment. (Figure 3). Comparing treatment groups (12 dSm-1, 16 dSm-1 and 20 dSm-1to control groups (0 dSm-1), 4 dSm-1 and 8 dSm-1 The length of the sunflower's roots and shoots was significantly decreased, especially at 14.1 dSm-1 NaCl. At all salt levels, the expansion of sunflower shoots were more impacted than growth of roots. At every salinity treatment, the weight of the fresh shoots and roots was likewise significantly impacted. Similar results were also observed by .
