The aim of this study was to investigate the effect of foliar application of salicylic acid (SA) on alleviating Zn stress in young wheat plants. Two rigorous pot experiments were conducted with two spring wheat cultivars growing on soil artificially contaminated with Zn. The experimental design included three levels of soil contamination with Zn: 0, 300 and 700 mg kg−1, and three levels of SA concentration: 0, 0.5 and 1 mM. Foliar spray of SA was applied twice at an interval of two weeks. Wheat biomass was harvested two months after plant emergence. Both cultivars showed similar biomass reduction due to Zn phytotoxicity, but differed in the accumulation and distribution of this metal in the plant. The positive effect of SA foliar application was obtained only for one of the two tested cultivars, where a reduction in the Zn translocation from the roots to the aboveground part was observed. As a consequence, the decrease in biomass caused by the toxicity of Zn was limited. A greater positive effect of SA application on wheat biomass was observed at 700 than at 300 mg kg−1 Zn in soil. The different responses of the cultivars to the SA was probably related to their different defense mechanisms against Zn stress.

The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 μM SA, T2: 200 μM SA, T3: 400 μM SA, T4: 600 μM SA, T5: 800 μM SA and T6: 1000 μM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 μM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 μM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh.Res. Agric., Livest. Fish.4(3): 157-164, December 2017

Loss of seed quality in soybean is a serious problem in tropical and subtropical region. Foliar application of salicylic acid (SA), GA3 and acetyl salicylic acid (50 ppm) at seedling and pod filling stage, K2HPO4 (2%), a-tocopherol (100 ppm) at flowering and pod filling stage was done on soybean varieties – NRC 7 and JS 335. Foliar application of SA showed positive effect on seed yield, seed health, germination and seed vigour during storage. Plant height was significantly improved by the GA3 spray in both the varieties. Significantly higher seed yield was obtained with foliar spray of a-tocopherol. Application of SA was found effective to protect plants from various diseases to get quality seed. a-Tocopherol and K2HPO4 treatment significantly reduced MDA production in seeds. a-Tocopherol application increased super oxide dismutase activity as a result the lipid peroxidation of seed during storage was significantly reduced. Application of a-tocopherol, K2HPO4 and salicylic acid improved the storage or keeping quality of soybean seed.

In order to achieve optimal plant growth and production, essential nutrients must be readily available in adequate quantities and in a balanced proportion to give a good yield, especially cauliflower which has health benefits that may not be found in many other plants. For this purpose, this experiment was carried out during the seasons 2020-2021 in the on station of Bangladesh Agricultural Research Institute, Khulna under Smallholder Agricultural competitiveness project. Although the treatments showed a positive effect on yield, quality and economics but, T1 revealed most significant influence on all parameters under study as compared to T0 (control). For micronutrients and hormone, T1 treatment produced the highest curd yield (29.99 t ha-1) and the lowest (17.04 t ha-1) was control from the varietal effect the highest curd yield was (35.14 t ha-1) from V4 (It Amazuku 33) and the lowest was (16.21 t ha-1) from V5 (BARI Fulcopi-1). In case of combined effect, the highest curd yield (45.16 t ha-1) was obtained from T1V4 and the lowest curd yield (10.27 t ha-1) from T0V1. Therefore, it can be suggested that the highest curd yield and good shape cauliflower curd can be obtained application of Zn 8.83 kg/ha, B 3.5 kg/ha, Ma 8.43 kg/ha and Flora (Hormone) 2 ml/1 L of water. Therefore, foliar application of micronutrients and hormone is suitable way to feed the cauliflower crop to enhance the marketable yield and quality.

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

Abstract Background Generally, zinc (Zn) is an essential element and acts as a plant nutrient, but at higher concentrations, it is toxic. Higher uptake and translocation of Zn into plant tissues can cause serious physiological and biochemical alterations. However, salicylic acid (SA) is an endogenous regulator of growth and signaling molecule responsible for inducing environmental stress tolerance in plants. Therefore, spray application of SA could provide protection against several types of stresses such as Zn toxicity. In this context, the ameliorative effect of SA (0.5 and 1 mM) on Salvia officinalis L. under Zn stress (40 mM) was studied. Results Zn stress decreased growth, chlorophyll content, essential oil yield and peltate glandular trichome density. This toxicity can be linked to a strong accumulation of Zn in the various parts of the plant. In addition, Zn stress disturbed nutrients assimilation (K, P and Ca). However, spray of SA, particularly at 0.5 mM improved all parameters studied under both Zn and normal conditions. The positive effects of SA under Zn stress condition may be due to the decrease of Zn accumulation in different parts of the plant. This decrease was accompanied by an increase in K, P and Ca content. In addition, the histological study of S. officinalis leaves showed the presence of two types of glandular hairs, the peltate and capitate glands. In the leaves of stressed plants, we noticed the presence of glands with deformations in the form of pockets in the number of one or more as well as the glands with an oval form. On the other hand, all these abnormalities glands were not detected in stressed plants that were sprayed with SA. Therefore, the absence of these anomalies under the effect of SA showed the remedial effect of this growth regulator. Conclusion The findings of the present work suggest that spraying SA maybe useful for improving the plant growth in Zn-contaminated areas.

A field experiment was carried out to screen the best foliar concentration of salicylic acid (SA) out of 25, 50, 75 and 100 mg L-1 for its effect on various growth and yield parameters like number of leaves, plant height, number of fruits plant-1, fruit dimensions, leaf chlorophyll content and yield plant-1 in three chilli cultivars. The selected chilli cultivars included were Sky-Land-II, Sky-Land and 1130. The experiment was conducted in field area of the Department of Horticultural Sciences, The Islamia University of Bahawalpur, Pakistan during 2017. Results indicated that different levels of SA significantly increased plant growth and yield parameters, but the level of SA @ 75 mg L-1 highly improved the studied parameters in selected cultivars. Moreover, foliar spray of SA significantly increased growth in selected cultivars; however, Sky-Land-II performed better in response to different concentrations of SA. In conclusion, foliar spraying of 75 mg L-1 SA could be recommended to chilli growers under arid region of Bahawalpur for growing cultivar Sky-Land-II.

An experiment was conducted to study the effect of PGRs { gibberellic acid (10 ppm), brassinolide (0.5 ppm), salicylic acid (100 ppm), ascorbic acid (100 ppm), benzyl amino purine (5 ppm)} and nutrients { K2SO4 (0.5%) + FeSO4 (0.5%) + Borax (0.3%) mixture and 19:19:19 (1%) mixture} on growth, NR enzyme activity, proline, soluble protein content and yield of bhendi hybrid (COBh H 1) under saline condition. The treatments were given at 25 and 45 DAS as foliar spray. The results showed that, nitrate reductase activity, soluble protein and plant growth were reduced under saline condition where as proline content was increased compared to absolute control. Foliar application of PGRs and nutrients enhanced the NR activity, proline, soluble protein and plant growth under saline condition. Among the PGRs and nutrients, foliar application of salicylic acid (100 ppm) and brassinolide (0.5 ppm) showed the better performance to mitigate the effect of salinity.

Abstract This research was conducted as a combined analysis with four replications in two years (2018 ‒ 2019). Treatments were irrigation up to 90%, 50%, and 20% field capacity (as normal irrigation, moderate and severe water deficit stresses, respectively) and foliar application of natural regulators (untreated as control, salicylic acid, spermidine, and methanol). Increasing water deficit stress was led to a significant increase in essential oil percentage and proline content and a significant decrease in yield parameters and seed yield. Most of the traits (except the percentage of essential oil) were affected by natural growth regulators. The highest seed yield (1,127.59 kg/ha), plant biomass (5,426.92 kg/ha), essential oil yield (22.67 kg/ha), and proline content (29.34 μmol/g fresh weight) were obtained in methanol treated plants under normal irrigation. However, the highest amount of these traits under moderate and severe water deficit was recorded for salicylic acid-treated plants. Therefore, foliar spray of methanol was a useful treatment for non-stress conditions, but, application of salicylic acid was the superior treatment for reducing the negative effects of water deficit stress on Foeniculum vulgare.

The present research was designed to determine the effects of exogenous salicylic acid (SA), selenium (Se) and silicon (Si) on the resistance of canola (Brassica napus L. cv Okapi) seedlings to salt stress. Foliar application of SA (0.1 mM) in canola plants under drought stress for 25 days exhibited a significantly positive effect on shoot dry mass and raised the levels of total chlorophyll as well as boosting the activity of superoxide dismutase (SOD) and catalase (CAT). In addition, soil application of silicon (0.35 g Na2SiO3/kg soil) had ameliorative effects on canola root growth under drought. It is concluded that SA and Si enhanced the salt tolerance of canola by protecting the cell membrane against lipid peroxidation. However, the foliar application of Se (10 mg/l) had no ameliorative effects on canola growth and antioxidant capacity under drought stress, as could be judged by accumulation of malondialdehyde (MDA).
