“…Control treatment T 0 (K 0 Zn 0 ) produced the lowest straw yield (4.91 t/ha) which was identical with T 1 (K 0 Zn 100 ) treatment (Figure 1). In agreement with our results, Kausar et al (2016); Kamrani et al (2013); Heidari and Jamshid (2010) found that grain and straw yields of wheat increased due to application of potassium and zinc fertilizers at higher doses in salt-stress conditions.…”

Appropriate nutrient management could increase crop productivity in saline areas by reducing the harmful effects of soil salinity. A field experiment was carried out at farmer’s field of Botiaghata, Khulna to investigate the mitigation of soil salinity by efficient management of potassium and zinc fertilizers in rice. BRRI dhan53, a salt-tolerant rice cultivar during aman season, was used as a test crop. The experiment was laid out in a randomized complete block design with three replications where sixteen treatment combinations were used in a factorial arrangement. Potassium and zinc nutrients were supplied from potassium sulphate and zinc sulphate, respectively and they were applied in two splits, first split during final land preparation and second split at maximum tillering stage. Recommended doses of N, P and S fertilizers were applied to all the experimental plots. Results revealed that plant height, panicle length, number of effective tillers and grains per panicle increased significantly due to application of K and Zn fertilizers. All the yield contributing parameters showed higher values in T15 (K200Zn200) treatment compared to other treatments. Grain and straw yields of BRRI dhan53 responded significantly to the different treatment combinations. The highest grain yield (4.46 t/ha) was obtained in T15 (K200Zn200) treatment and the highest straw yield (6.27 t/ha) was also obtained in the same treatment. Higher doses of potassium and zinc also increased nutrient uptake (N, P, S and Zn) by BRRI dhan53. The K+/Na+ ratio was also found higher in grain (0.319) and straw (0.301) in T15 treatment. Therefore, result of the experiment indicated that application of higher doses of K and Zn fertilizers could alleviate the adverse effects of salinity in rice production by increasing nutrient uptake and maintaining higher K+/Na+ ratio.

Salt-tolerant wheat cultivars are essential for sustainable wheat production and global food security. The present study aimed to establish a reliable screening protocol as well as successfully isolated the potential salt-tolerant wheat varieties by discerning morpho-physiological parameters with multivariate analysis. Seventeen wheat varieties were evaluated at 0, 12, 15 and 18 dSm-1 salinity levels in a hydroponic culture system at the seedling stage. Moreover, in vitro callusing responses of four selected varieties were determined to clarify the salt tolerance capability at 0, 9, 12 and 15 dSm-1 salt treatments. The seedling growth of most wheat varieties was highly interrupted and reduced by the toxic effects of salinity, however, some varieties such as BARI Gom-32, BARI Gom-33, BARI Gom-31, BARI Gom-30, and BARI Gom-28 showed the lowest reduction under all salinity stress conditions. The total salt tolerance index (TSTI) showed that the cultivar BARI Gom-33 was the most salt-tolerant followed by BARI Gom-32 and BARI Gom-30 whereas BARI Gom-25 was identified as the most sensitive. These results were strongly supported by the principal component analysis (PCA) and Ward’s Methods Euclidean based clustering. In vitro results revealed that the lowest reduction of callus induction was recorded in BARI Gom-33 which might show the greatest tolerance to salinity by improving morpho-physiological characteristics against salt stress. Therefore, the identified genotypes might be employed as donor parents to develop salt-tolerant and high-yielding cultivars in the wheat breeding programme.

“…The obtained results are consistent with the most previous investigations, which pointed out the same direct correlation between antitranspirant materials and some element nutrient to tissues of soya bean (Yadav and Dashora 2003). Kausar et al (2016) reported that the nutrient uptake and accumulation such as Ca, Mg, K, and P were gradually increased by K application particularly under saline environments in both wheat genotypes. Abd El-Samad et al (2018) found that the potassium application that increased significantly gained the highest percentage values of total soluble solids (TSS), protein, N, P, and K of bean plants.…”

Potential role of kaolin or potassium sulfate as anti-transpirant on improving physiological, biochemical aspects and yield of wheat plants under different watering regimes

Background and objective: Certain substances with some physical and chemical activities can be used to decrease the transpiration rate and alleviate plant water stress through rising leaf resistance to the diffusion of water vapor. Wheat plant is considered as one of the most important and economic winter plants. So, the objective of this work is to evaluate the response of wheat plants (Triticum aestivum L.) cultivar Gimeza 7 to various concentrations of foliar application of anti-transpirant substances as kaolin (3 and 6%), potassium sulfate (100 and 200 mg/l). Materials and methods: Two pot experiments were conducted during 2016/2017 and 2017/2018 successive growing winter seasons under greenhouse conditions at the Experimental Station, in the National Research Centre, Egypt. The plants were exposed to various levels of water holding capacity (WHC) 80, 60, and 40%. Results: Water stress led to a decrease in growth parameters, yield components, photosynthetic pigments, and carbohydrate contents as compared to 80% of WHC. Meanwhile, water stress caused significant increases in some compatible solute (total soluble sugar, free amino acids, and proline) and some antioxidant enzymes activities. Foliar treatments of wheat plants with kaolin or K 2 SO 4 led to an increase in growth parameters, yield components, photosynthetic pigments, and carbohydrate constituents. More accumulation of the organic solutes of leaves (total soluble sugar and free amino acids), antioxidant enzyme activities, and some minerals (N, P, K, and Ca) was observed. Data also illustrated that the nutritional values of the grain yield of wheat were also improved when sprayed with kaolin and K 2 SO 4. Conclusion: The used substances are safe for the environment, and for the plant, potassium is an essential nutrient and its ability controls several biochemical and physiological responses in plants. Kaolin also can ameliorate plant physiology and consequently lead to higher yield production.
