“…A detailed ecophysiological analysis of the influence of water stress on soybean is beyond the scope of the study. Lower top assimilatory surface size in soybean with limited water might be due to decreased photosynthetic rate and worsened partitioning of dry matter to produce more leaves, as was shown in Iran (43°N) during 2016 (Mondani et al 2019). Our results agreed well with those of Mondani et al (2019), who also reported a decline in dry matter production of water-stressed soybean due to a reduction in maximum leaf expansion.…”

Water stress modifies canopy light environment and qualitative and quantitative yield components in two soybean varieties

et al. 2021

The influence of three levels of water supply (unlimited (WW); water stress during flowering (RO); rainfed (P)) on radiation properties and yield of two soybean varieties (Sinara, Sin; Sigalia, Sig) were evaluated. Sin is considered to be tolerant to water stress. The effect of leaf area index, year, variety, and meteorological variables on evapotranspiration (ET) was analysed by hierarchical regression. This study attempted to identify how water supply affects the crop–light relationship between photosynthetically active radiation (PAR) transmission and radiation use efficiency (RUE), which were involved in qualitative and quantitative traits related to soybean production (biomass and yield attributes: seed yield, 1000-grain weight, oil and protein content). Unstandardized coefficients of air temperature (Ta) showed that a 1 °C increase in daily mean Ta induced a higher ET, on average 0.16 mm day−1. Soil moisture strongly affected sowing time. When averaged across three seasons at flowering, 97.7, 95.1 and 97.3% of incoming PAR were intercepted by the canopies of plants in WW, RO and P, respectively. The average extinction coefficient (k) and RUE pooled across both varieties were 0.42 and 1.32 g MJ PAR−1 for WW, and 0.46 and 0.98 g MJ PAR−1 for RO, respectively, compared with 0.44 and 1.15 g MJ PAR−1 for P. As expected, water treatment significantly affected all yield traits: RO decreased yield whereas WW increased yield compared to P. Practically, both varieties are suitable for cultivation under water stress during flowering but Sin showed greater yield under unlimited watering and rainfed conditions.

“…The resilience of soybean to water stress can also be expressed through its decline in assimilatory surface (Mondani et al 2019). The magnitude of LAI is directly proportional to the crop's ability to absorb solar radiation (Purcell 2000), and this is related to photosynthetic potential and crop productivity.…”

A field experiment was carried out with three bacterial inoculants: HiStick® Soy, Nitragina, Nitrazon and the control. Number and dry weight of nodules were significantly higher with inoculation of bacterial inoculants compared to the control. In 2017, the most pods per plant were obtained after the use of Nitrazon or HiStick® Soy, while in 2018, after the use of HiStick® Soy or Nitragina. In 2018, the highest 1000 seed weight was obtained after the use of Nitragina. In 2017, the seed yield was the most favourably affected by the inoculants HiStick®Soy (3.31 t ha -1 ) and Nitrazon (3.37 t ha -1 ) and in 2018, by HiStick® Soy (3.92 t ha -1 ) and Nitragina (3.87 t ha -1 ). High Soil Plant Analysis Development (SPAD) and Leaf Area Index (LAI) readings, were observed with HiStick® Soy.

“…Acidification of the medium is correlated with phosphorus solubilization by acid phosphatase activity, indicating that some microorganisms have developed enzymes capable of releasing inorganic phosphate from organophosphate complexes, in addition to the activity of this enzyme proving to be a good indicator for the mineralization of organic phosphorus (Kumar, 2016;Tenga et al, 2019). Likewise, the capacity for nitrogen fixation is common to many groups of microorganisms and their association due to its beneficial potential has been studied for application in the most varied agricultural crops (Mondani et al, 2019;Schmidt et al, 2019).…”

Rose essential oil is rich in compounds widely used by the pharmaceutical and cosmetic industry, due to the biological activities it presents. However, obtaining oil is costly, as the yield per plant is low, which requires several techniques that aim to increase its production. The application of growth-promoting bacteria has been studied for this purpose. Thus, the objective of this work was to select efficient bacteria for production and evaluate their influence on the phytotechnical characteristics and composition of the essential oils of roses. Seven species of bacteria were evaluated for the potential to promote growth in vitro, being tested for nitrogen fixation, phosphate solubilization, protease production and auxin production. From bacteria tested, four were selected and inoculated on rose plants of cultivar Black Prince to evaluate the influence on phytotechnical variables of flower and stem and the oil production. The evaluation of the production of roses was performed through the characteristics of the flowers (size, weight, and diameter of the stem) and floral bud. The essential oils from the inoculated flowers were extracted and evaluated in terms of content, yield, and chemical composition. The application of B. acidiceler, B. subtilis and B. pumilus resulted in flowers with a diameter up to 29% larger. The floral stem was increased by up to 24.5% when B. acidiceler and B. pumilus were used. Meanwhile, the stem diameter was around 41% greater in the presence of B. acidiceler, B. subtilis and in the control. Bacillus pumilus also increased the weight of fresh petals (104%) and essential oil yield (26%), changing the chemical composition of the extracted essential oil. Thus, it is concluded that B. acidiceler, B. pumilus, and B. subtilis improved the phytotechnical characteristics of roses. Among bacteria, B. pumilus increased the essential oil content as well as positively changed the chemical composition of the extracted essential oil.
