Published: July 2023

The COVID-19 pandemic made it more difficult for entrepreneurs to obtain capital finance from banks. As a result of disruptions caused by the COVID-19 pandemic, entrepreneurs found alternative means of obtaining capital finance in the form of crowdfunding. Crowdfunding has the potential to help entrepreneurs get access to finance. The prevalence of crowdfunding campaigns in Africa is relatively low compared to most developed economies around the world. The objective of the study was to determine the role of social networks on crowdfunding performance during the COVID-19 pandemic in Africa. A total of 859 crowdfunding projects in Africa were analysed in the study. The ordinary least squares (OLS) and probit models were estimated in the analysis. The duration, comments, and target amount variables were found to be negatively and significantly associated with crowdfunding success in Africa. Conversely, the presence of videos, updates and backer’s variables were positively and significantly associated with the success of crowdfunding campaigns. The study contributes to new knowledge by revealing the influence of the COVID-19 pandemic and the role of social networks on crowdfunding performance in Africa. Furthermore, the study makes a policy recommendation to African governments on the need to craft policy instruments that will foster the development of crowdfunding sources which will ultimately mitigate the problem of credit rationing by banks which curtail the growth of entrepreneurs.

Women play a critical role in the economic and social well-being. Therefore, measuring life satisfaction of women is important to see their view of life. Life satisfaction measures the overall satisfaction in life. The aim of this study is to determine whether there are differences in life satisfaction among working women in Malaysian from the perspectives of demographic characteristics. The measure of life satisfaction was based on the Life Satisfaction Scale. Purposive random sampling method was used to choose the sample. The analysis is based on responses of 302 working women. Independent t-test and one-way ANOVA is used to the test the variables. Overall, the life satisfaction of the working women was found to be moderate in the study. The results of the study found significant differences in life satisfaction with regards to marital status, age, occupation, income, spouse’s education and spouse’s income. However, ethnicity, education, spouse’s age, spouse’s occupation and number of children did not show to be significantly different. The Ministry in charge of women, family and society development could provide the necessary assistance to women who are having problems that could affect their life satisfaction. Women who are interested in opening their own business could also be assisted by the relevant agencies to improve in their income. Through this, they can assist their family financially. More policies supporting women should be introduced to assist or strengthen the position of women to move up professionally and socially.

Biomass fuel, an economical organic renewable source of energy, is still intensively used for burning purpose in majority areas of rural Punjab. It mainly includes agricultural crop residues and animal dung which is easily available and found in abundance. But it’s the dilemma of present times, that while on one side biomass fuel is facilitating the lives of residents of rural areas by providing them a low-cost solution to meet their energy requirements, at the same time it is posing a potential risk to health of rural women. These women are directly exposed to the health hazards of gases being released from burning of biomass fuel due to longer contact hours. This research was conducted with the purpose to investigate how domestic cooking fuel is affecting the health and lives of women directly or indirectly. This research work was conducted in year 2019, in three districts of Punjab, Okara, Hafizabad and Multan, with 480 data samples collected evenly in the research area. There were two slots, based on different age groups, defined for data collection. In response to investigating different social parameters and their association with health impact, it was found that rural women with age group between 20 to 40 (slot 1) were suffering from mental health issues at higher rate of 64 % while those with age group above 40 (Slot 2) were found at higher risk to physical health issues with 83 % of the studied population. Similarly, rural women belonging to slot 1, exhibited 87 % of workload and domestic fuel management responsibilities. The findings of this research exhibited significant variation of health impact on women for different sources of biomass fuel.

Recently, hybrid communication is gaining more and more importance in our society (Bielinis, 2020) - due to the COVID-19 pandemic and social restrictions, people were forced to use remote means of communication, thanks to which it was possible not only to avoid, but also to effectively manage the COVID-19 pandemic. However, hybrid communication is relevant not only in this context - thanks to it, members of various organizations can carry out continuous communication and connect 24/7 from anywhere in the world. A study by Berger et al. (2021) found that before the global COVID-19 pandemic, only 35% of organizations used/aspired to use a hybrid work model, but now even 77% use this work model. (Berger, Weber & Buser, 2021). Organizations that previously conducted their activities in a contact manner and could not imagine an effective flexible combination of remote and contact work methods, now face new challenges of internal processes, employee performance and change management. However, properly chosen methods of information transfer help to ensure targeted achievement of organizational goals, change management and smooth internal operational processes. Therefore, in the context of the hybrid work model, active and purposeful communication becomes particularly significant. The aim of the article is to determine the features of hybrid communication when applied to business development in Lithuania. The research showed that hybrid communication encouraged the introduction of new information dissemination channels in the organization, more efficient time management and increased employee productivity. However, the study also diluted the challenges of hybrid communication: i.e. the adaptation of new employees, the problem of receiving feedback, the abundance of e-mails and the growing social exclusion of employees, the consequences of which could be examined in other studies.

The use of e-commerce has a lot of potential to make the lives of older people better. It could give them power, the ability to manage and control their finances, lower care costs, and make them less reliant on others, so they could live on their own. Using a questionnaire survey, this study looks at whether individual characteristics of older Greek people could affect their adoption of e-commerce. Eight variables that could be linked to adoption: gender, age, marital status, residential status, level of education, experience with information technology, employment status, and income were examined. The results show that age, gender, residential status, education level, employment status, and income all play a big role in how older people shop online. The results of this study help service providers and the government understand how older people's individual characteristics affect online shopping. As a result, this knowledge would help them find and use the right strategies to improve online shopping.

Published: July 2023

Cultural values play a crucial role in the formation of individuals’ behaviour. With the emergence of social networking sites, which have formed a parallel world to the real world, the behaviour of individuals and their motives to engage in electronic word of mouth (eWOM) on social media platforms has become extremely important for brands. Due to a relative lack in studies focusing on the cultural difference-based impact of social relationships on eWOM in social media, the present study seeks to address this gap as its broad objective is to investigate the effect of social relationship variables on eWOM in social media by comparing two different cultures, namely Syria and Hungary in order to explore whether social relationships exert a more significant impact on eWOM in a collectivistic society than in an individualistic one. An explanatory research design was adopted and the data was collected by means of a questionnaire survey. The final sample included 113 Syrian and 90 Hungarian respondents, all of them aged 35 or below. It was found that tie strength among young adults has a more positive impact on eWOM in Syria than in Hungary, while no homophily impact was found on eWOM in either. Regarding the other social relationship variables examined in the study (trust, normative and informational influences), the results showed that they do not have a more positive impact on eWOM in Syria than in Hungary. The research is believed to have contributed to previous investigations on the impact of social relationships on eWOM via social media by providing insights into the role of a cultural value dimension in determining the extent to which individuals are affected by their cultural background, whether collectivistic or individualistic, when they interact in social media platforms. At the same time, it is acknowledged that the study has limitations thus future examinations are necessary.

Socio-economic status (SES) is conceptualized as the social and economic standing or class of an individual or family. Socio-economic status of farmers is an important variable in agricultural social sciences studies. While it is often estimated with various indicators, however, these indicators are inconsistent and irrelevant. An attempt was made to extract the various variables used to measure the socio-economic construct and redefined it into a precise concept. A systematic review of the studies reporting the socio-economic conditions of farmers was performed by adopting the The preferred reporting items for systematic reviews and meta-analysis (PRISMA) best practices method and identified 235 studies. Vote counting was used to generate the determinants of SES in the selected studies. It was observed that the precise concept of SES in agricultural studies was not found. Literature Review identified 39 variables in measuring the socio-economic conditions of farmers. These variables were observed, redefined, and relevant indicators were classified into two groups: social and economic status. These include their education, occupation, income per capita, expenditure, savings, land ownership, livestock status, indebtedness, area under crops and material possession in house and farm, housing conditions, social participation, family size, caste, marital status, dependency ratio, extension contact, and mass media participation. The above-mentioned variables under the social and economic standing of farmers could be adopted by the researchers, and policymakers based on the areas of interest in studying the SES of farmers.
Japanese funeral rites in late modernity

Published: July 2023

Funerals in Japan are always a highly serious and solemn affair. Japanese funerals whether they are ancient or modern are always official activities with ancient traditional practices. Often, there are no bells, whistles, drums, or fanfare. The only exception is when the Japanese Shinto Buddhist priest beats a single and mournful drum. In 1867, Emperor Komei died and it took over a month to get him buried. This was because of political upheaval and other intervening requirements. When Emperor Meiji died in July 1912, the courtiers also had to go through several weeks of preparation before the onset of public mourning. Naturally, mourning by the immediate royal family members always took precedence. Later, when Emperor Taisho’s funeral had to take place, it also took 1 month of rituals and preparations before public mourning could commence. Taisho’s funereal activities followed Emperor Meiji’s funeral model. Japanese funerals were also costly in the past as they are today. In the late 1990s and early 2000s, a single Japanese funeral would cost at least US$30,000 compared to a few thousand in Singapore and other Asian states. Funerals are even cheaper in Europe and North America. In Japan, each person or family attending a funeral wake would have to present to the widow or widower a cash gift of a few 100,000 yen. This cash gift is called koden. Japanese funeral rites are part of a set of clearly defined rituals that reflect the nature of the society and the status or class of the deceased. This article focuses on the important aspects of Japanese Shinto-Buddhist funeral rites.

The problem of unemployment among youths has remained unabated. This has cast doubt on the methods of instruction by lecturers. This study takes a critical review of some of the previous studies with an emphasis on employment statistics and employability skills (ES). The paper identifies the basic elements of ES and the latest statistics on youth unemployment in Africa, particularly Nigeria. The aim is to sensitize education managers of higher institutions in Nigeria about the danger inherent in turning out graduates massively without the corresponding skills to match them adequately with the world of work. Findings show that there is a persistent rise in the rate of youth unemployment because what the schools offer is not compliant with the labor market demand. The resulting skills played a significant role in increasing unemployment among tertiary education graduates. Therefore, the higher education curriculum needs to be modified to reflect the skills required by employers.

Cuscuta Reflexa from Convolvulaceae family is a plant with a variety of ethnic medicinal uses along with antioxidant activity. Hence it was planned to evaluate the hepatoprotective activity with methanolic extracts of whole plant of Cuscuta reflexa (MECR) and aqueous extracts of whole plant of Cuscuta reflexa (AQECR). Hepatoprotective activity of both the extracts was studied against galactosamine induced hepatotoxicity in rats. Biochemical parameters Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Serum alkaline phosphatase (ALP), Serum direct bilirubin (BILD), Serum total bilirubin (BILT), Serum albumin (ALB), Serum total proteins (PRO), Serum cholesterol (CHO), and histopathological changes of livers were assessed in control/toxicant/standard/and extract treated animals with galactosamine induced hepatotoxic models in rats. In LD50 studies for MECR and AQECR up to the maximum dose level of 2000 mg/kg dose no mortality was observed in any of the animals, indicating the practically nontoxic. When compared to toxicant control groups both the extracts have significantly reduced the paracetamol induced elevated levels of serum ALT, AST, ALP, BILT, BILD, CHO, and elevated the levels of ALB and PRO. The histopathological changes (steatosis), necrosis etc. Were partly or fully prevented in animals treated with the two extracts. MECR and AQECR showed a significant hepatoprotective effect against galactosamine induced hepatic damage. The medium and high doses of AESCR and AQESCR (200 and 400 mg/kg) treated groups showed better hepatoprotective activity when compared to standard drug silymarin (25 mg/kg). Studies for MECR and AQECR up to the maximum dose level of 2000 mg/kg dose no mortality was observed in any of the animals, indicating the practically nontoxic. When compared to toxicant control groups both the extracts have significantly reduced the paracetamol induced elevated levels of serum ALT, AST, ALP, BILT, BILD, CHO, and elevated the levels of ALB and PRO. The histopathological changes (steatosis), necrosis etc. Were partly or fully prevented in animals treated with the two extracts.

Published: July 2023

Technological developments in the field of music are currently experiencing progress, including the formation of computer-based recording, namely the Digital Audio Workstation (DAW). Monitor speakers are one of the most important components of a DAW. A good selection of monitor speakers can support the quality of sound produced by a home recording or recording service provider. The many variations and specifications of monitor speakers on the market make it difficult for users to choose based on four criteria: price, response frequency, design criteria, and power output. So it is necessary to make an application that can determine recommendations for purchasing monitor speakers by applying the Fuzzy Multiple Attribute Decision Making Algorithm. The results obtained in this study show that of the five alternative monitor speakers, KRK ROKIT G4 5 has the highest alternative preference rating of 2.2,5 so it can be used as a reference monitor speaker for home recording.

Research carried out in 2021 at the Jeser Al-Musayyab Company, Baghdad, Iraq, determined the molecular variations among 10 inbred lines of maize (Zea mays L.), for use in the future production of promising F1 hybrids. DNA sequencing random polymorphism technology using Inter Simple Sequence Repeats (ISSR) with five primers (UBC 834, UBC 835, UBC 856, UBC 866, and UBC 897) assessed the genetic variations among the 10 inbred lines of maize. All five primers produced 29 bands, averaging 5.8 strips each primer. The four primers, UBC 834, UBC 835, UBC 866, and UBC 897, had produced the same and highest number of proliferators with molecular weights ranging from 100 to 2000 bp. The primer UBC 856 showed the lowest number, with a molecular weight of 100–500 bp. The total number of polymorphs was 24, with a percentage of 82.4%, with the lowest (80%) polymorphs recorded in the primer UBC 856. The least discriminatory efficiency and ability values were 17.24% and 16.66%, respectively. Relying on binary data and genetic divergence using the UPGMA method to create a genetic kinship tree, the maize lines were separated into two groups, i.e., A, B, secondary, and sub-secondary groups. The highest genetic similarity (with the lowest genetic divergence) was estimated according to the Nei and Li coefficient of 0.23 between the two lines HS and S-10. The presented findings can provide further guidance and help analyze the genetic diversity among the maize populations.

Developing high-yielding wheat varieties tolerant to abiotic and biotic stresses is a challenge wheat breeder currently face. Wheat Research Institute (WRI), Ayub Agricultural Research Institute (AARI), Faisalabad, Pakistan, has released 65 wheat varieties, including MH-21, for several zones since its establishment in 1906. MH-21, with the varietal code V-12304, gave 11.2% and 10.28% more grain yield than the check variety (Faisalabad-08), respectively, in preliminary (2011–2012) and regular yield trials (2012–2013). Then, testing it in outstation yield trials proceeded over 21 locations in Punjab province (2013–2014) and 18 locations all over Pakistan (2014–2015, 2017–2018, and 2019– 2020) for yield and disease constancy, simultaneous with agronomic field trials and quality lab testing during 2014–2018 and 2014–2016, respectively. It exhibited an amber seed color, semi-erect growth habit at booting, erect flag leaf attitude, hairiness auricle, awned yellowish ear, and elevated shoulder and beak shape of glumes traits. DNA fingerprinting of MH-21 ensued to compare its genetic background with previously registered 21 wheat varieties. Given the promising stable performance in multi-locations over the years for better grain yield, nutritional quality, and resistance against rusts, the Punjab Seed Council approved V12304 in 2021 with the name „MH-21‟ for general cultivation in irrigated areas of Punjab, Pakistan.

Assessment of botanical and genetic collection of soybean cultivars transpired during 2021–2022, for morphological and yield-related traits and their impact on nodule bacteria and soil fertility, at the Dormon Scientific Experimental Station, Institute of Genetics, Academy of Sciences of the Republic of Uzbekistan, District Kibray, Tashkent region, Uzbekistan. The soybean cultivars, grown in a randomized complete block design, had a factorial arrangement with three replications. Results revealed that in the botanical collection, the highest seed yield per plant came from the soybean cultivar K-2600 (48.3 ± 1.30 g), 1000-grain weight from Bk-105 (215.9 ± 0.15 g), and the number of grains per plant from the genotype K-2600 (346.4 ± 6.48). Moreover, in the genetic collection, the high oil content resulted in the genotypes Gen-15 (20.11%), Gen-13 (19.46%), and Gen-11 (19.40%). The higher values of the total protein content emerged in the soybean cultivars, Ehtiyozh (34.09%) and Gen-9 (33.74%), Gen-19 (34.72%), and Gen-26 (33.08%). Among the two types of soybean collections studied, the most substantial number of root nodules appeared in the cultivar Sochilmas (96.65 ± 0.11) during the pod formation phase. The recorded highest amount of soil microelements, according to soil analysis, was at the sowing site of the soybean cultivar, Genetiс-1 and on average, the soil samples contained N-NO3 (28 mg/kg), mobile P2О (212.3 mg/kg), and volatile trace element K2О5 (36 mg/kg), found to remain in the soil after crop harvesting. The conclusion based on the results indicates that the local soybean cultivar Genetik-1 has a more positive effect on improving soil fertility versus the other genotypes in both collections.

The presented study, held at the Research cum Instructional Farm of the College of Horticulture and Research Station, Jagdalpur, Chhattisgarh, India, ran during the Rabi season of 2021, to investigate superior radish cultivars for selection having high yield potential and better quality root for Bastar plateau. The experiment, laid out in randomized block design (RBD), had 15 treatments and three replications. Observing high genotypic and phenotypic coefficient of variation was for the following traits: dry and fresh weights of roots, plants, and leaves; root and leaf yields; days to 50% germination; the diameter and length of the root, North-South and East-West spread of the plant; plant height, and the number of leaf plant-1, having recorded significant heritability and high genetic advance. Similarly, high heritability showed for root yield and fresh and dry weights of roots. Moderate heritability levels appeared for the traits, viz., the plant’s dry weight and the root diameter. The genetic gain resulted high for characters, viz., root yield and fresh and dry weights of roots. High heritability followed by high genetic advance indicates that selection may be effective for improving such characteristics. Root yield (t ha-1) exhibited a highly significant positive correlation with the fresh weight of the plant at the phenotypic and genotypic levels, followed by dry weight of roots, dry weight of the plant, East-West spread of the plant, the diameter of the root, and leaf yield plot-1 . The fresh weight of roots had the maximum positive direct effect on root yield in the genotypic path, followed by the dry weight of roots and the plant, the East-West spread of the plant, the diameter of the root, and leaf yield in radish. The selection of these characters can benefit in improving the yield of radishes.

Soybean (Glycine max [L.] Merr.) is an economically important oilseed crop with an annual increase in growing grain demand. Soybean is a moderately salt-tolerant crop; however, salt stress conditions can affect its growth and yield-related traits and, eventually, reduce productivity. In saline soils, one of the techniques to increase soybean productivity is to use rhizobia inoculation. Although, using industrial rhizobia-based biofertilizers is often ineffective due to their lack of adaptability to salinity. Injecting soybeans with salt-tolerant and growth-promoting rhizobia helps mitigate the effects of salt stress harmful to crop plants. The recent study sought to isolate local strains of salt-tolerant rhizobia, studying its ability to increase soybean tolerance to salt stress conditions. Twenty-four local salttolerant rhizobium isolates underwent isolation from root nodules of soybean grown on saline soils. Studying their basic morphological and biochemical characteristics and ability to withstand salt stress led to the final selection of five salt-tolerant strains. The rhizobium strains were able to synthesize metabolites that stimulate growth and help reduce salt stress in plants. The study of rhizobia nodulation ability under saline conditions resulted in selecting the three most efficient strains from the Bradyrhizobium japonicum species. Inoculation of soybean seeds with salt-tolerant rhizobia proved to mitigate the adverse effects of salinity on plant growth by increasing the root size and the number of nodules in the roots. Thus, the study establishes that inoculation of soybean seeds with local salttolerant rhizobia enhances soybean tolerance to salt stress and improves crop growth and adaptation to soil salinity. Using isolated local strains of salt-tolerant rhizobia will help provide a key and environmentally friendly approach to solving the problem of salt stress for sustainable agriculture.

Pinus merkusii is a potential wood that naturally grows in Central Sumatra (Kerinci) and North Sumatra (Aceh and Tapanuli), Indonesia. The Kerinci landrace has a different morphology from the other two Sumatran Pinus landraces, namely, Aceh and Tapanuli, but its placement is at the same taxonomic level. Hence, additional characters need evaluation to validate taxa on P. merkusii landrace belonging to Kerinci. This study aims to identify differences in genetic characters between Kerinci and Aceh (Rao and TAHURA [Taman Hutan Raya]) landraces using SRAP for long-term use and future conservation. DNA extraction ran from the leaves of 24 individual trees belonging to three populations of P. merkusii, i.e., one naturally occurring population in Kerinci and the two cultivated populaces found in Rao and TAHURA, Indonesia. Using seven SRAP combination primers, the analysis revealed an immense variety of alleles (bands). Overall, the amplification produced 62 bands, with nine, on average, per primary pair. However, most bands were polymorphic (91.79%), and only 0.57% were monomorphic. With 45% informative bands, the Kerinci landrace has the highest band variation. A combination of primer C (Me1 + Em3) at 900 bp and primer I (Me3 + Em1) at 1050 bp band size indicated specific bands that served as molecular characteristics. A crucial molecular characteristic distinguishes the landraces of P. merkusii found in Kerinci and other populations in Rao and TAHURA, Indonesia. The study revealed superior genetic variation among the P. merkusii populations evaluated.

Three bacterial isolates selected as plant growth-promoting endophytic bacteria (PGPEB) from “Klutuk” banana (Musa balbisiana L.) gained scrutiny for first-time testing on black rice. The presented study pursued an investigation on the impact of endophytic bacteria inoculation obtained from “Klutuk” banana plants on the growth and production traits of black rice. For this research, the three bacterial isolates (K10, K324, and K111) served as inoculums for black rice seeds, testing for synergism. The three isolates inoculation into black rice plants used both single and consortium inoculation methods. With agar media, black rice growth observation began 14 days after plantation (DAP) while on soil, at 30 and 140 DAP with inoculation. Three isolates did not show any antagonistic reactions. Overall, isolate K10 showed less significant improvement in growth and yield traits of black rice compared with two other isolates, i.e., K324 and K111. With agar media, the endophytic bacteria inoculations did not show a significant effect on the growth of black rice, and even isolate K324 was inhibiting in action. However, on soil media, isolate K324 significantly enhanced the number of roots and shoot length in black rice compared with the control at 30 DAP. The single inoculation with isolate K111 has caused increased productivity based on the weight of the root, dry grain weight per clum, plant height, root length, leaf length, and panicle length in black rice. Isolate K324 promotes the growth of black rice on the soil media at 30 DAP, while isolate K111 improves the production traits on the soil media at 140 DAP. The study findings provide a significant basis for the positive impact of endophytic bacterial inoculation on black rice growth and yield traits.

Heterotic groups are necessary for high vigor in hybrid rice. However, hybrids produced from crosses between parents from different rice subspecies (i.e., Indica × Japonica) have extensive incompatibility issues exhibited by low seed sets. The study objectives were to evaluate the heterosis in grain yield and yield-related traits between hybrids produced from low and high parental genetic distances (PGDs) and demonstrate the heterotic group approach in rice. From PGDs, eight and three hybrids were assigned to the low and high PGD hybrid groups, respectively. Neighbor-joining clustering and model-based population structure analyses classified the hybrid parents into four heterotic groups, with the low and high PGD hybrid groups found consisting of intra-subpopulation and intersubpopulation crosses, respectively. Replicated yield trials conducted at Beaumont, Texas, transpired in 2019 and 2020. The hybrids exhibited normal seed sets, with at least one of each hybrid's parents determined to possess the wide compatibility S5n allele necessary for normal seed sets in wide crosses. Trait and standard heterosis values estimates included the number of days to heading, plant height, tiller density, and grain yield. Higher trait values and heterosis for tiller density and grain yield occurred in the high than the low PGD hybrid group, especially in the inter-subpopulation crosses with indica rice. PGD had consistent positive correlations with heterosis for grain yield (r = 0.41 to 0.60) and tiller density (0.28 to 0.36) in both years. PGDs aid in determining highly heterotic cross combinations for tiller density and grain yield and in forming heterotic groups. Heterotic grouping is advisable through cluster and structure analyses of genome-wide markers instead of identifying genetically-distant crosses based on pedigree information.

Organic fertilizers‟ usage enhances crop productivity and improves soil fertility and the surrounding environment in livestock complexes. The presented study assessed the effect of biofertilizers and poultry-based organic fertilizers on rhizospheric microbial diversity, yield attributes, and productivity of spring barley (Hordeum vulgare L.). Conducting field experiments started in 2021 in Northern Kazakhstan's Southern carbonated chernozem of the steppe zone. Poultry manure application had three doses (5, 10, and 15 t ha-1), while four types of biofertilizer of microbial origin consisted of Compo-MIX, Agro-MIX, Agrarka, and Trichodermin-KZ. The poultry-based organic manure resulted in the highest number of nitrogen-fixing bacteria. By treating seeds with biofertilizers, Agrarka and Trichodermin-KZ, the organotrophic bacteria dominated the barley rhizosphere. The seed treatment with Agro-MIX, Trichodermin-KZ, and organic fertilizer (at the rate of 5 and 10 t ha-1) resulted in a predominance of nonsymbiotic nitrogen-fixing bacteria. Combined analysis of variance revealed that, on average, the organic and biofertilizers significantly increased plant viability, 1000-grain weight, and grain productivity. Combined application of poultry manure (10 t ha-1) and biofertilizer Trichodermin- KZ gave the highest average values of grain productivity, i.e., 1,550 and 1,490 kg ha-1 (15.5 and 14.9 quintal ha-1), respectively.

Sweet corn is one of the essential food crops in Indonesia because of its many benefits, such as, being a source of carbohydrates, oil, flour, animal feed, and others. Corn demand increases yearly, needing a large land area to meet its requirements. However, planting maize during the dry season or low rainfall faces more challenges. Therefore, using drip irrigation is a solution to ensure corn growth and sustained optimal production. The presented study aimed to determine the effects of drip irrigation on the production of two varieties of sweet corn (Zea mays saccharata Sturt) and began from February to May 2021 at the Faculty of Agriculture, Universitas Teuku Umar, Meulaboh, West Aceh, Indonesia. The study used a randomized design (split-plot) each for two irrigation levels: without drip irrigation (T0) and drip irrigation (T1) in main plots on two sweet corn varieties, Bonanza and Paragon. The parameters observed were cob diameter with cornhusk (mm), cob diameter without cornhusk (mm), cob length with cornhusk (cm), cob length without cornhusk (cm), cob weight with cornhusk (g), and cob weight without cornhusk (g). Analysis of variance showed that the drip irrigation treatments had no significant effect on all the recorded parameters. However, the varieties had a highly relevant impact on the cob diameter and length and considerably influenced the cob weight. Then again, the sweet corn varieties showed nonsignificant differences for all other variables.
