Beneficial Action

Soybeans are one of the most produced grains in the world, and because of the high cost of nitrogen fertilizers, new technologies in the inoculation of diazotrophic bacteria have been developed. The objective of this study was to evaluate the effect of Bradyrhizobium-based inoculant doses and Lipo-chito-oligosaccharide molecules (LCOs), together with bacterial protector as an additive, compared to a conventional inoculant in the inoculation of soybean seeds. The experiment was carried out in a greenhouse, with soil from a Red Oxissol of sandy texture. The experimental design was in randomized blocks with 3 replicates, the treatments being distributed in a 5 x 2 factorial scheme (2 inoculants and 5 inoculant doses). The seeds of the soybean cultivar M8866 were inoculated and seeded in the pots containing 11 L of substrate, where two plants remained for 45 days. Nine biometric-productive parameters were evaluated. Increasing the dose, regardless of the inoculant, provided an increase in root length and probably active nodules. In general, it was possible to observe statistical superiority of the inoculant with technologies integrated in relation to the conventional one, independent of the dose, when comparing the inoculants with respect to these two variables. Furthermore, the inoculant with integrated technologies provided a higher mass of fresh and dry matter of the nodules with the application of the highest inoculant dose (3.6 billion UFC mL-1). It was noted that increasing the dose of conventional inoculant did not cause the increase of fresh and dry matter mass of the nodules such as the inoculant with integrated technologies, suggesting the beneficial action of the bioprotectant and of the LCOs molecules.

The aims to evaluate the soybean seeds quality in response to the vigor level of seeds and the fertilizing distribution system in the sowing row. The experimental design was random blocks organized in factorial scheme, being two growing environments (Passo Fundo – RS and Ernestina – RS) x three vigor levels classified as high, medium and low (90%, 70% and 60% vigor, respectively) x three fertilizing distribution systems (no distribution, conventional and overflow), and the treats disposed in four replicates. The measured characters were thousand seeds mass, germination, accelerated aging, electric conductivity, viability and vigor, shoot and root length, shoot and root dry matter and field emergency. Vigor and physiologic quality of produced seeds are intimately related to characteristic of environment of production and vigor level of used seeds. Elevated physiologic potential are obtained in seeds produced in specifically using seeds with high vigor independent of the fertilizer distribution system.

The use of inoculated microorganisms on seeds has increased in Brazil, as they help on the fixation and use of nutrients by plants, promoting increasing yields, mainly due to the reduction in the application of nitrogen fertilizers. The aim of this study was to evaluate the influence of single inoculation and co-inoculation of Azospirillum brasilense and Bradyrhizobium japonicum bacteria on seeds and foliar inoculation on soybean, in the region of Tangará da Serra – MT, Brazil. The experimental design used was a randomized block with 9 treatments and 4 replicates. The treatments were composed by using B. japonicum and A. brasilense bacteria in different combinations and times of application on seeds and sprayed on the leaves. The use of A. brasilense together with B. japonicum significantly improved the agronomic characteristics of the evaluated soybean cultivar. There was an increase in yield with the use of A. brasilense through the co-inoculation technique when compared to the single use of Bradyrhizobium. The use of co-inoculation at V3 soybean stage promoted higher nodulation and yield than the standard inoculation performed in the seeds, ensuring better results of nodulation and yield besides increasing the size of the soybean root system, when there and co-inoculation techniques were implemented.

Nowadays, the predominant technique for the commercial propagation of guava seedlings is through cuttings, using herbaceous cuttings that need a specialized infrastructure with intermittent misting, clean water, exhausters, water filters, and fans. As an alternative to plant propagation by cuttings, this study aimed to evaluate the influence of concentrations of indolebutyric acid (IBA) on the rooting of branches of the guava cv. Paluma by air-layering. The experimental design was in randomized blocks, with four replications and 10 air layers per plot. The treatments consisted of six concentrations of IBA powder mixed with industrial talcum: 0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg.kg-1. Four adult guava parents that were in the off-season period were used. For the preparation of the air layers, the stems were girdled with a 4.0 cm width, using a steel blade, by removing the bark until exposing the cambium region, followed by IBA application and wrapping of the branches with a plastic bag containing moist organic substrate. The following variables were evaluated 120 days after air-layering: percentage of rooted and callused air layers, longest root length, and root dry matter. The analysis of variance indicated no significant differences between the IBA concentrations for all variables, but the rooting percentages were high (68.6 to 92.2%) regardless of the application of the exogenous auxin.

In the world auto market, top three companies are VW(Volkswagen), Runault-Nissan-Mistubishi, and Toyota. About some selected countries and areas, China, England, Italy, Australia, Germany, Turkey, Russia, Sweden, USA, Brazil, UAE, Japan, Vietnam and Thailand are more competitive. However, the situation is different. Seeing monopolistic market countries and areas, Saudi Arabia, Taiwan, Korea, Malaysia, France, India, and Pakistan, in particular, the influence of Japan to Taiwan, India, and Pakistan is very big. But in Korea and France, their own companies’ brands occupy the market. In Japan domestic market, the overall situation is competitive. Almost all vehicles made in Japan are Japanese brand. From now on, we have to note the development of electric vehicle (EV) and other new technologies such as automatic driving and connected car. That is because they will give a great impact on the auto industry and market of Japan. Now Japan’s auto industry is going to be consolidated into three groups, Honda, Toyota group, and Renault-Nissan-Mitsubishi group for seeking the scale merit of economy. Therefore, I will pay attention to the worldwide development of EV and other new technologies and the reorganization of auto companies groups.

Kia ora and welcome to the second issue of BackStory. The members of the Backstory Editorial Team were gratified by the encouraging response to the first issue of the journal. We hope that our currentreaders enjoy our new issue and that it will bring others to share our interest in and enjoyment of the surprisingly varied backstories of New Zealand’s art, media, and design history. This issue takes in a wide variety of topics. Imogen Van Pierce explores the controversy around the Hundertwasser Art Centre and Wairau Māori Art Gallery to be developed in Whangarei. This project has generated debate about the role of the arts and civic architecture at both the local and national levels. This is about how much New Zealanders are prepared to invest in the arts. The value of the artist in New Zealand is also examined by Mark Stocker in his article about the sculptor Margaret Butler and the local reception of her work during the late 1930s. The cultural cringe has a long genealogy. New Zealand has been photographed since the 1840s. Alan Cocker analyses the many roles that photography played in the development of local tourism during the nineteenth century. These images challenged notions of the ‘real’ and the ‘artificial’ and how new technologies mediated the world of lived experience. Recorded sound was another such technology that changed how humans experienced the world. The rise of recorded sound from the 1890s affected lives in many ways and Lewis Tennant’s contribution captures a significant tipping point in this medium’s history in New Zealand as the transition from analogue to digital sound transformed social, commercial and acoustic worlds. The New Zealand Woman’s Weekly celebrates its 85th anniversary this year but when it was launched in 1932 it seemed tohave very little chance of success. Its rival, the Mirror, had dominated the local market since its launch in 1922. Gavin Ellis investigates the Depression-era context of the Woman’s Weekly and how its founders identified a gap in the market that the Mirror was failing to fill. The work of the photographer Marti Friedlander (1908-2016) is familiar to most New Zealanders. Friedlander’s 50 year career and huge range of subjects defy easy summary. She captured New Zealanders, their lives, and their surroundings across all social and cultural borders. In the journal’s profile commentary Linda Yang celebrates Freidlander’s remarkable life and work. Linda also discusses some recent images by Friedlander and connects these with themes present in the photographer’s work from the 1960s and 1970s. The Backstory editors hope that our readers enjoy this stimulating and varied collection of work that illuminate some not so well known aspects of New Zealand’s art, media, and design history. There are many such stories yet to be told and we look forward to bringing them to you.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Improving nitrogen use efficiency is a significant scientific problem to be solved. Two maize hybrids JD27 (Jidan 27) and SD19 (Sidan 19) were selected to study the effects of nitrogen levels on root characteristic parameters and plant dry matter accumulation, distribution and transportation. We set five different nitrogen levels, which were nitrogen deficiency (000N), low nitrogen (075N), medium nitrogen (150N), high nitrogen (225N) and excessive nitrogen (300N). The results showed that the root length and root surface area of JD27 were significantly higher than those of SD19 under 075N. With the increase of nitrogen levels, the root difference among varieties gradually decreased. The root length, projection area, total surface area and total volume reached the maximum values at silking stage. The average root diameter kept stable or decreased slowly with the growth stage. The dry matter accumulation of JD27 was higher than that of SD19 at all growth stages. Increasing the amount of nitrogen fertilizer can promote the transport of dry matter to grain and improve dry matter transport efficiency after anthesis. Under the treatment of medium and high nitrogen fertilizer, maize was easy to obtain a higher yield, but excessive nitrogen fertilizer inhibited the increase of yield. This study provides theoretical and practical guidance for maize production techniques.

The Impact

AbstractThe COVID-19 pandemic and infection control measures had an unavoidable impact on surgical services. During the first wave of the pandemic, elective surgery, endoscopy, and ‘face-to-face’ clinics were discontinued after recommendations from professional bodies. In addition, training courses, examinations, conferences, and training rotations were postponed or cancelled. Inadvertently, infection control and prevention measures, both within and outside hospitals, have caused a significant negative impact on training. At the same time, they have given space to new technologies, like telemedicine and platforms for webinars, to blossom. While the recovery phase is well underway in some parts of the world, most surgical services are not operating at full capacity. Unfortunately, some countries are still battling a second or third wave of the pandemic with severely negative consequences on surgical services. Several studies have looked into the impact of COVID-19 on surgical training. Here, an objective overview of studies from different parts of the world is presented. Also, evidence-based solutions are suggested for future surgical training interventions.
