Abstract This study was carried out during two successive seasons 2018 and 2019, on soybean plants (Glycine max L. cv. Giza 90) atQaha Research Station, Plant Protection Research Institute, Qalyoupia governorate, Egypt. In order to investigate the effect of curcumin and glycyrrhizic acid ammonium salt (GAS-NPs) as a foliar application under water deficit on growth, yield, anatomical and chemical parameters. The obtained results revealed that, under water deficit over seasons significantly decreased all morphological and yield characters. Glycyrrhizic acid ammonium salt nanoparticles gave the highest averages of plant height, branches and leaves number and fresh and dry weight of plant at 1 mM. Moreover, number of pods, 100 seed weight and seed yield (kg/ha) increased significantly as a result of spraying with glycyrrhizic acid ammonium salt nanoparticles under water deficit. As to anatomical studies, water deficit decreased the values of the leaf and stem anatomical parameters. Treatment with curcumin or glycyrrhizic acid ammonium salt nanoparticles at 50% of water holding capacity increased the thickness of mid vein and xylem and phloem tissues. Likewise, such treatment increased stem diameter due mainly to the increase in the thickness of cortex, phloem and xylem tissues compared with control.

To investigate the effect of nano-zinc fertilizer on growth, yield and mineral status of cotton plants grown under salt stress, a pot experiment was set up in the greenhouse of the National Research Centre. The treatments were as follows: (I) diluted seawater: 10% (S1), 20% (S2) and tap water as a control (S0), (II) 100 ppm (NZn1), 200 ppm (NZn2) nano-zinc and distilled water as a control (NZn0). Irrigation with 10 and 20% seawater decreased dry weight (DW) of leaves by 11.53 and 43.22%, while decreases in bolls were 15.50 and 71.65%, respectively. Except for root DW and top/root ratio, the measured growth parameters were increased as nano-zinc concentration increased. As for the interaction between treatments, the highest DW of stem, leaves and bolls resulted from the addition of NZn2 under normal condition, followed by NZn2 x S1 and the next was NZn2 x S2. The foliar application of 200 ppm nano-Zn led to mitigating the adverse effect of salinity and confirmed that diluted seawater could be used in the irrigation of cotton plant. However, phosphorus fertilizer should be added with nano-Zn application to avoid P/Zn imbalance. Some elements’ status and their ratios were recorded.

The objective of this investigation was to study the helpful effects of foliar application with antioxidant citric acid in combos with some micronutrients on growth, yield and a few chemical constituents of maize (Zea mays L.) plants. The plants were grown up in clay soil, and foliar sprayed with eleven treatments (0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45 and 0.5%) of combined fertilizer (citrine) which contains (15% citric acid, 2% Fe, 2% Mn and 2% Zn). The obtained results indicated generally that each one studied vegetative growth parameters (i.e. plant height, stem diameter, number of leaves /plant, dry weight of leaves) similarly as grain yield /fed. and some of their components (i.e. ear length, ear diameter, number of rows/ear, number of grains/row, grain weight/ear, weight of 100 grain and ear weight/plant) and some chemical constituents of leaves (chlorophyll a, b, total caroteniods, anthocyanin, total carbohydrates, total and reducing sugars, total free amino acids, total indoles, nitrogen, phosphorous and potassium) and grain protein %, were accrued with application of the various treatments. The maximum values were obtained from the treatment of 0.3%. On the contrary citrine treatments minimized reducing sugars and free phenol in leaves as compared to the control. The simplest results were obtained by the application of citrine treatment at 0.3%. Hence, it can recommend using citrine fertilizers as foliar application at the speed of 0.3% for improving growth, yield and chemical constituents of maize plants.

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.

Impacts of various concentrations of salicylic acid (SA) on cucumber (Cucumis sativus L.) seedling characteristic were evaluated under different water stress levels by using a factorial arrangement based on completely randomized design with three replications at experimental greenhouse of Ferdowsi University of Mashhad, Iran. The studied factors included three water deficit levels (100% FC, 80% FC, and 60% FC) considered as first factor and five levels of SA concentrations (0, 0.25, 0.5, 0.75, and 1 mM) as second factor. Results showed that foliar application of SA at the highest concentration enhanced leaf area, leaf and dry weight while decreased stomatal conductance under high level of water deficit stress. Though, severe water deficit stress sharply raised the SPAD reading values. In general, exogenous SA application could develop cucumber seedling characteristic and improve water stress tolerance.

Due to the importance of soybeans worldwide, there is a constant search for products or management systems that aim to increase the productivity of this crop. In this sense, some products that have amino acids in their composition have been used, however, there is still a lack of studies that aim to show the isolated effect of amino acids on growth parameters. Therefore, the present study aimed to evaluate the effect of the application of amino acids in the treatment of seeds and of the leaf in the soybean crop. Experiments were carried out in a greenhouse and in the field with the application of glutamate, phenylalanine, cysteine, glycine as a seed treatment (ST) and also as foliar application (FA) at the V4 growth stage. The dry mass accumulation of root, stem, leaves, total and yield of a soybean crop were evaluated. In addition, leaf element concentration in leaves was also evaluated. The use of phenylalanine in ST promoted the best results on stem mass, leaves, pods and total dry mass, with an increase of up to 152%, as compared to control. This same treatment led to higher productivity, with a 46% increase in relation to the control. In relation to foliar concentration of elements, the most effective application is the one that is carried out in both modes of application (ST and FA), mainly with glutamate and glycine. Therefore, the application of amino acids, especially in seed treatment promotes the greater accumulation of dry mass and productivity in soybean plants.

A field experiment on rice (Oryza sativa L.) crop was conducted at Rice Research Station, Kaul (Kaithal), India during kharif season of 2017 and 2018 to evaluate the optimum schedule of nitrogen application in the rice grown under early and late planting conditions. The treatments consisted of three timings of transplanting (3rd week of June, 1st week of July and 3 rd week of July), four levels of N (90, 120, 150 and 180 kg Nha-1) and four timings of N fertilizer application (½ at transplanting + ½ at 21 DAT, ½ at 21 DAT + ½ at 42 DAT, 1/3 at transplanting + 1/3 at 21 DAT + 1/3 at 42 DAT and LCC based N supply) and were laid out in split-plot design with transplanting time and N levels in main plots and N application time in sub-plots. The growth parameters (plant height, number of tillers/m2 and dry matter accumulation/m2), yield attributing characters (number of panicles/m2 and grains/panicle) and yield (grain and straw yield) of rice crop reduced significantly under late planting (3rd week of July) as compared to that under the two earlier plantings (3rd week of June and 1stweek of July) whereas the two earlier plantings were at par in respect of these parameters. The growth, yield attributes and the yield increased with every increase in N application rates but the increase was significant up to 150 kg Nha-1. The highest yield was (7.33 tha-1), however, obtained with the crop transplanted early (up to1st week of July) and supplied with 150 kg Nha-1.Application of N in three equal splits (at 0, 21 and 42 DAT or as per LCC schedule), being at par, resulted into higher yield (grain and straw) than the N application in two equal splits. The net returns and B: C ratio increased appreciably with increase in N application levels upto 150 kg Nha-1 obviously due to increase in crop yield.

ABSTRACT Water deficit is a limiting factor for the soybean yield; it triggers different physiological and anatomical adaptations that have deleterious effects on the plants and can affect the selectivity of herbicides, causing production losses. In this context, the objective of this work was to evaluate the action of the chlorimuron-ethyl herbicide when applied at different stages of soybean plants, using conventional and transgenic cultivars, and different soil water potentials. A rate of 20 g ha-1 of the chlorimuron-ethyl herbicide was applied to two soybean cultivars (MG/BR46-Conquista - conventional, and BRS-Valiosa-RR - transgenic) at two phenological stages (V2 - first fully expanded trifoliate leaves, and V4 - third fully expanded trifoliate leaves), using three soil water potentials (-0.03 MPa, -0.07 MPa, and -0.5 MPa). Phytotoxicity, and plant height were evaluated at 3, 7, 14, and 21 days after the herbicide application. The shoot dry weight, root dry weight, and root system nodulation were evaluated. The soybean plants had lower phytotoxicity when subjected to application of chlorimuron-ethyl under water deficit conditions. The use of chlorimuron-ethyl reduced the growth and biomass of soybean plants and affected the plants' root system nodulation. The transgenic cultivar (BRS-Valiosa-RR) presented better performance when subjected to a moderate water deficit (-0.07 MPa), which contributes to biological nitrogen fixation.
