SummaryThe goal of this research is to determine the effects of different levels of water deficit (I100: full irrigation, I65: 35% deficit, I40: 60% deficit and I0: no irrigation) on yield and chemical composition of soybean [Glycine max (L.) Merr.] grown in Srem region of Serbia. Water deficit significantly affected the yield and chemical composition of soybean seeds. The lowest (1.63 t/ha) and the highest (3.21 t/ha) seed yields were obtained from I0and I65treatments, respectively. Furthermore, the highest protein (1092 kg/ha) and oil (563 kg/ha) yields were observed in I65treatment. Lower and higher irrigation levels from I65decreased the protein and oil yields. Our data indicated that irrigation generally increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. It was clearly observed that full-watered treatment (I100) provided no potential benefit in terms of soybean yield and chemical composition. For higher economic yield and good nutritional quality, water-saving treatment I65could be suitable in soybean management in Srem region of Serbia as in other regions with similar soil and climate conditions.

The goal of the present research is to determine an effective sprinkler irrigation strategy for soybean [Glycine max (L.) Merr.] in temperate climate conditions, in order to maximize yields and seed quality. A three-year field experiment with four different irrigation treatments was conducted on Calcic Chernozem in the Vojvodina region of Serbia. The irrigation regimes included: no irrigation; full irrigation (I<sub>100</sub>); and two deficit irrigation treatments – 65% of I<sub>100</sub> (I<sub>65</sub>) and 40% of I<sub>100</sub>. The irrigation treatments generally had a statistically significant effect on the increase of soybean yield and protein content. Irrigation did not have a significant effect on the oil content. In general, irrigation increased K, P, Mg, Mn, Cu, Zn and B concentrations and decreased Ca and Fe concentrations in soybean seed. The results show that irrigation with the largest amount of water (treatment I<sub>100</sub>) provided no potential benefit in terms of soybean yield and chemical composition. Treatment I<sub>65</sub>, which exhibited the most favourable watering conditions, is the best choice to maximize yield and ensure a good chemical composition of soybean under these agroecological conditions.

The aim of this study is to calculate the physical properties of eight springs of the water of the Dhofar region in Oman using physiochemical parameters like pH, total dissolved solids (TDS), conductivity, turbidity, and dissolved oxygen (DO). The chemical properties estimated the concentrations of the metals in springs of water and specified the best healthy spring of water depending on the percentage difference between the actual and normal range set by the World Health Organization (WHO). Eight samples for each test were collected from eight springs of water, namely, Ain Hamran, Ain Deribat, Ain Tobruk, Ain Al-Nabi Ayoub, Ain Atom, Ain Jarziz, Ain Sahlnot, and Ain Razat using an atomic absorption spectrophotometer (AAS) to study the chemical composition of the samples. Ain Jarziz represented high quality water because the percentage difference between actual and WHO was 78.78% compared to Ain Al-Nabi Ayoub, where the difference percentage was 105.95 %. Quantity of dissolved solid particles has a big effect on TDS and conductivity compared to the turbidity. Identification system was used to evaluate the effect of the quality of the chemical composition on the turbidity for Ions of Cl-1, So4 -2, Ca+2, Na+1, Mg+2, and K+1 to be equal to 99.52%, 75.4%, 92.548%, 95.346%, 98.011%, and 97.33 %, respectively. However, more studies are required to conform with the outcomes of this research employing this energetic technique.

In the absence of Bradyrhizobium japonicum populations in the soil, yields of field-grown soybean (Glycine max (L.) Merrill) usually respond to inoculation with B. japonicum. The objective of this research was to determine the relationship between numbers of B. japonicum per seed in inoculants and soybean nodulation and yield. A total of six field experiments were conducted in 1989 and 1990 on new soybean soils. In dilution trials, Grip inoculant was applied to provide approximately 106, 105, 104, and 103B. japonicum per seed at two locations in 1989. Nodule number and mass, as well as seed yield, increased curvilinearly upward with increasing log10 most probable numbers (MPNs) of B. japonicum. The yield response curve was best fit by a cubic equation, which accounted for 97% of the variation in yield. Seed yields increased 19% (1.83 to 2.13 Mg/ha) from 105 to 106B. japonicum per seed. In field experiments involving 8 commercial inoculants in 1989 and 10 in 1990, and conducted at two locations in each year, responses to increasing log MPNs in the inoculants also were concave upwards and cubic. In the two years, 78 and 46% of the yield variation was accounted for by log MPN per seed. Increasing MPN per seed from 105 to 106 improved yields in first-time fields by an average of 24%, indicating the present minimum standard of 105B. japonicum per seed should be increased. Key words: most probable numbers, response to inoculation, nodulation, Glycine max (L.) Merrill.

This article describes an idea about improving the aged soybean seed quality through ozone application based on the consideration that the ozone's oxidative and reactive nature could preserve agriculture commodities during storage. Using soybean seeds that were naturally aged in room temperature storage (25±5°C) for two months, gaseous ozone's efficacy in rejuvenating the aged seeds was examined. The aged seeds were divided into three different packages: open container, polypropylene woven sack, and vacuum polyethylene plastic. Gaseous ozone at a capacity of 150 g/h was continuously exposed on packaged seeds during six months of storage under low temperature (18±5°C). The authors found that ozone in specific limit exposure could improve physiological characteristics and inhibit some chemical properties deterioration of aged soybean seeds during storage. Our technique allows for improvement in germination percentage and germination rate of aged seeds in the fourth month of ozone exposure (p<0.05). However, these physiological parameters decreased significantly in the sixth month of ozone exposure, signing that prolonged ozone exposure would lead to adverse effects due to excessive oxidation. The result also showed that ozone storage significantly retard the elevation of moisture and free fatty acid content of aged soybean seeds. The ozone effectiveness evaluation is confirmed in all packaging conditions, but the vacuum packaging offered better preservation on almost entirely seed quality parameters during storage, except for protein. This research result provides a promising technique to restore aged seed quality and can be used for better seed provision in the seed industry.

Pre-storage seed invigoration treatment in freshly harvested soybean seeds (Glycine max [L.]Merrill, cv. Soyamax) with powdered crude plant materials (red chilli powder@1g/kg of seed; neem leaf powder@2g/kg of seed), chemicals (iodinated calcium carbonate@2g/kg of seed; para-amino benzoic acid and ferulic acid@500mg/kg of seed) and; pharmaceuticals (aspirin @50mg/kg of seed) significantly improved germinability, field performance and productivity over control. Among the treatments, Ferulic acid, aspirin and para-amino benzoic acid showed better results in improving storability and field performance. The wet treatments, soaking-drying showed adverse effect on germinability due to soaking injury. Biochemical studies revealed that the activity of dehydrogenase, amylase (a, b free and b bound), catalase and peroxidase enzymes were higher in all dry treated seeds compared to the untreated control. Among the treatments, ferulic acid followed by aspirin has shown higher enzyme activity. On the basis of the results, pre-storage dry treatments with ferulic acid, aspirin and para-amino benzoic acid may be suggested for improving storability and field performance of stored soybean seed.

An experiment was carried out at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during three consecutive seasons in 2004-2006 to find out the effect of sowing date on physiological quality of soybean seed. The experiments included six sowing dates viz. 4 Nov, 24 Nov, 14 Dec, 3 Jan, 23 Jan and 12 Feb and two cultivars namely G-2 and PB-1 in Rabi 2004-05; four sowing dates viz. 25 Jul, 14 Aug, 3 Sept and 23 Sept and three cultivars namely G-2, PB-1 and BS-5 in Kharif II 2005; four sowing dates viz. 26 Nov, 16 Dec, 5 Jan, and 25 Jan, and two cultivars viz. G-2 and PB-1 in Rabi 2005-06. The experiments were conducted in split-plot design with three replications. Results revealed that cultivar G-2 had higher germination and vigour than cultivar PB-1 or BS-5 in all the three seasons. November and December sowing produced seeds with higher germination and vigour for all the cultivars in Rabi season. On the other hand, September sowing produced seeds with high germination and vigour during Kharif II. The study indicated that soybean seeds with high germination and vigour could be obtained by sowing during November to December in Rabi season and August to September in Kharif-II season.

The paper presents the result of a triennial field experiment (2013‒15), aiming to determine the influence of irrigation, nitrogen fertilization, and cultivars, as well as their interactions on the yield and chemical properties of the soybean seeds. Four soybean cultivars (Lucija, Vita, Ika and Tena) of different maturity groups were investigate as a sub‐subplot factor (C). The main plot factor (A - irrigation) resulted in a statistically very significant (P≤0.01) seed yield in all three years, and it was found out by an analysis of variance. The subplot factor (B - nitrogen fertilization) had an impact on the grain yield depending on the research year, while sub‐subplot factor (C-cultivar) significantly affected all examined traits. The factor interactions and their significance varied by the research years. The seed yield achieved in 2013 (3883 kg ha-1) indicated a great importance of all factors’ interaction. The correlations between a seed yield and a protein and oil concentration were determined during the research.

The objective of this work was to evaluate the chemical composition of the macronutrients: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S), and micronutrients: boron (Cu), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn), and the elements aluminum (Al) and sodium (Na) measured in soybean seeds from different producing regions of Brazil. This work was carried out by sampling 2543 lots of soybean seeds produced in the 2009, 2010, 2011 and 2012 growing seasons. There is high variability of macro and micronutrients concentration in soybean seeds produced in several regions of Brazil. The nitrogen, potassium, phosphorus, and calcium are the most pronounced macronutrients in soybean seeds. Among the micronutrients, iron, manganese and zinc are those with more evidence. Understanding macro and micronutrients variability is critical for improving management and fertility treats in soybean seed production fields.

Effects of pre-sowing soybean seed inoculation with Bradyrhizobium japonicum alone or with mixed inoculants containing soybean rhizobia and Azotobacter chroococcum were compared. In the pot experiment all the tested strains of soybean rhizobia in pure cultures or in mixtures with A. chroococcum significantly improved nodulation of soybean plants and seed yields of this crop. In micro-plot experiments pre-sowing soybean seeds treatment with the inoculant containing the most effective strain 94P of B. japonicum alone or with the mixed inoculant of strain 94P and A. chroococcum were equally effective in improving nodulation intensity and seed yields of soybean in comparison to the uninoculated soybean.
