A field experiments were conducted during the two summer seasons of 2015 and 2016 in saline soil (ECe = 9.0 dSm-1), at Fayoum province, Egypt to study the effect of ascorbic (AsA), as foliar application alone or combined with cyanobacteria (CB) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 54. Treatments comprised 2 ascorbic acid (AsA) levels with or without seed inoculation with cyanobacteria (CB). They were 1 mM AsA, 2 mM AsA, 1 mM AsA + CB and 2 mM AsA + CB in addition to the control treatment in which seeds were not received CB and their plants were sprayed with distilled water. Results could be summarized as follows: increasing the addition of ascorbic acid concentration up to 1Mm with combination of CB increased significantly values of growth attributes (e.i., plant height, of leaves no. /plant, shoot dry weight and leaf area), photosynthetic pigments (chlorophyll a, b and carotenoids), physiological responses (total soluble sugars, proline and soluble phenols) as well as the head diameter, seed yield/ plant, 100 seed weight and seed yield (t ha-1). Also, N, P, K, Fe, Mn, Zn and oil percentage of sunflower seeds with compared to control treatment in both years. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the concentration of ascorbic acid 1Mm combined with CB in both seasons

Selenium (Se) has been recently reported to play a crucial role in ameliorating the negative impact of abiotic stress, including salinity, on several plant species. Two field experiments (2016/17 and 2017/18) were carried out to investigate the possible effect of exogenous Se application at two levels (25, 50 mg L−1) on growth, bulb yield, physio-biochemical attributes, and antioxidant activities of onion grown under saline (5.25 dS m−1) soil condition. Se (25 or 50 mg L−1) foliar application enhanced growth characteristics, as well as membrane stability index (MSI) and relative water content (RWC) as a result of the osmotic adjustment by accumulating more osmoprotectants and enhancing the activity of antioxidants defense system, thus improving photosynthetic efficiency and bulb yield. Proline, glycine betaine, choline, and total soluble sugars content were higher in leaves and bulbs of Se-treated plants under salt stress. Se (25 or 50 mg L−1) significantly increased the activities of enzymatic (ascorbate peroxidase, superoxide dismutase, and catalase) and non-enzymatic (ascorbic acid and glutathione) antioxidants in both leaves and bulbs of salt-stressed onion. Se application at 25–50 mg L−1 may find, in the future, a potential application as anti-abiotic stresses for improving plant growth and productivity under saline soil condition.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

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.

SUMMARYField experiments were carried out at Ludhiana in Punjab during 1982 and 1983 on the effect of foliar application of water spray or naphthalene acetic acid (NAA) at 100 and 200 mg/1 of water on the growth and yield of rice when applied at tillering and before panicle emergence stages of late-transplanted paddy grown under four levels of nitrogen (0, 60, 90 and 120 kg/ha). Foliar spray of NAA significantly increased the grain yield of paddy as compared with water spray under low levels of nitrogen (0 and 60 kg/ha) owing to increases in the number of ear-bearing shoots per plant, number of filled grains per panicle and grain weight. Chlorophyll content of leaves, leaf area index and interception of photosynthetically active radiation by the crop canopy also increased with foliar spray of NAA and application of nitrogen. Paddy responded significantly up to 90 kg N/ha in terms of grain yield whereas straw yield increased significantly up to 120 kg N/ha. However, grain mass declined significantly with increase in nitrogen from 90 to 120 kg/ha.

This experiment was suggested to study the beneficial effects of foliar application with propolis extract at the rates 0, 6000, 7000, 8000 and 9000 mg/L solution used as foliar application to spinach seedlings on growth, yield and some chemical constituents of spinach plants (Spinacia oleracea L.) grown under calcareous saline soil conditions. All experiments were achieved during the two successive seasons of 2016 and 2017. Results showed that increasing the rates of propolis extract as foliar application increased the growth parameters of the treated plants. The best result was obtained by the rate (8000 mg/L) as a foliar application in both seasons of the study. The same trend was also observed regarding all studied chemical constituents, i.e. chlorophyll a, b and total carotenoids concentration, anthocyanine, total carbohydrates, total and reducing sugars, total free amino acid, free proline, crude protein, total indoles, total phenols, N, P and K in leaves. Thus, the coincident application of propolis extract at (8000 mg/L) as foliar application ingredient is recommended for improving growth, yield and chemical composition of spinach plants and for overcoming the adverse effect of saline conditions.

Sesame cultivars perform differently in various environments comprising specific locations and years. Micronutrient fertilizers increase crop yields and can enhance resistance to environmental hazards and contribute to potential yield. For assessing the effect of environment and micronutrients, field experiments were carried out at three different locations (BARI, URF and NARC) of Pothwar region, Pakistan, in two succeeding years (2014, 2015). Four sesame cultivars and three micronutrients (Zn, B and Mn) with a control treatment were used in RCB design with a split-plot procedure and four replications. The results showed significant differences in the main effects of all tested factors (cultivars, micronutrients, locations and years). Maximum mean values of plant height, capsules plant−1, biomass yield and seed yield were recorded for SG-30, while TH-6 was the lowest for these parameters. Maximum mean values of capsule length, capsule weight, seeds capsules−1 and the weight of 1000 seeds were recorded for TH-6 but vice versa for SG-30. Maximum capsule length and seeds capsule−1 were observed at NARC, while other growth and yield attributes were maximum at BARI and URF, including biomass yield and seed yield. The interactive effect of cultivar × location × year was highly significant for all growth and yield traits except capsule length. Sesame cultivars revealed a differential response for all traits at three locations during both years. Application of micronutrients significantly augmented all growth and yield features of sesame. Micronutrient fertilizers (i.e., ZnSO4 at 10 kg ha−1, borax at 10 kg ha−1 and MnSO4 at 5 kg ha−1) would increase yield and yield-attributing traits in low- or medium-precipitation areas where suitable cultivars have been designated.

Under rain-fed conditions, foliar application of nutrients is an efficient tool to eliminate the adverse effects of nutrients shortage and helpful to catch the maximum yield of any crop. Field experiments were executed to evaluate the effect of foliar spray of different strengths and application times of Hoagland’s solution on growth and yield characteristics of chickpea (Cicer arietinum L.) under rain-fed conditions. The treatments consisted of distilled water (control), 25, 50, and 75% strength of Hoagland’s solution sprayed at 7, 14, and 21 days after crop emergence (DACE) on two chickpea cultivars C-44 and CM-72. In terms of growth and yield, CM-72 showed superiority over C-44. The 75% strength of Hoagland’s solution showed an improvement of 32.9, 37.9, 35.3, 13.5, and 35% in dry weight, plant height, 100- seed weight, seed yield, and biological yield, respectively when sprayed at 21 DACE than distilled water. However, the lower strength (25%) of Hoagland’s solution produced similar results to distilled water. It is recommended that under rain-fed conditions chickpea cultivar CM-72 should be cultivated with a foliar supply of 75% strength of Hoagland’s solution at 21 DACE to obtain the maximum growth and yield.

The current study was designed to assess the effect of different concentrations of silica oxide nanoparticles (SiO2NPs) (0, 30, 60, and 90 ppm) as foliar applications under three irrigation regimes i.e., irrigation every 3 days (IR3, control), irrigation every 6 days (IR6), and irrigation every 9 days (IR9) on growth, yield and certain metabolites of rice (Oryza sativa L. cv. EHR1). To achieve such a goal, 2 field experiments were conducted during the 2018 and 2019 seasons at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha Agricultural Station, Kafr El-sheik, Egypt. Firstly, the as-prepared nanoparticles of SiO2 were prepared from useless materials (RHs) which are considered as one of the bio burdens on the environment via treating with HCl and followed by drying and calcination. Consequently, the synthesis was examined by making use of advanced tools such as X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic light scattering (DLS) for illustrating the hydrodynamic particle size of SiO2NPs and scanning electron microscopy (SEM). The nanoparticles were formed with nearly spherical shape and small size. The results indicated that leaf area index, dry matter production, the number of panicles/m2, the number of filled grains/ panicles, 1000 grain weight, grain yield, and biological yield as well as chlorophyll content have witnessed a significant increase under irrigated application every 3 and 6 days. Whilst a prolonged irrigation regime up to 9 days recorded a remarkable decline in the aforementioned characteristics except for the number of unfilled grains/panicle which increased considerably in both seasons. On the other hand, proline concentration and the activity of the antioxidant enzymes were increased in both irrigated treatments every 6 and 9 days compared with control treatment (irrigation every 3 days). The foliar supplementations of (SiO2NPs) contributed to ameliorating all the aforementioned characteristics progressively up to the dosage of 90 ppm compared to control treatment (no Si/NPS application) in both seasons. Invariably, growth and yield parameters in water-stressed plants treated with SiO2NPs were higher than those in water-stressed plants without SiO2NPs addition. Based on that, it could be concluded that the foliar application of SiO2NPs can mitigate the adverse effect of water stress on rice plants.
