Abstract

Cotton processing plays a pivotal role in Uzbekistan’s agricultural-industrial integration, with technological advancements becoming increasingly vital for maintaining fiber quality. The ginning process, a key operation in cotton processing, often suffers efficiency losses due to moisture-induced fiber damage and mechanical wear of saw drums, particularly during autumn when cotton arrives with high humidity. Traditional ginning machines lack mechanisms to prevent raw roll formation, leading to fiber degradation and frequent downtime, with insufficient research focused on eliminating this core issue without compromising productivity. This study aims to develop an engineering solution that enhances the ginning process by addressing moisture-related challenges and mechanical limitations through a newly designed device. The proposed device eliminates the formation of raw rolls, increases fiber separation efficiency by over 30%, and extends the life span of saw drums by threefold. Additionally, it reduces downtime and energy consumption while improving fiber grade, ultimately increasing profitability. Unlike conventional ginning systems, the device integrates an optimized working chamber structure and innovative fiber cleaning mechanisms such as a drum grate with checkerboard-patterned needle heights, enhancing impurity removal without fiber loss. These innovations provide practical, cost-effective upgrades suitable for Uzbekistan’s cotton enterprises, aligning scientific research with industrial needs and promoting sustainable productivity gains. The study reinforces the value of industry-academia collaboration in generating adaptive technologies for context-specific agricultural challenges.

Abstract

Stunting in children under five remains a significant public health issue in Indonesia, particularly in West Sumatra, where prevalence rates exceed the national average. Addressing this challenge requires improving nutritional intake, focusing on essential micronutrients like zinc (Zn) and iron (Fe). Biofortification is a promising agricultural strategy to enhance the nutritional quality of staple crops such as rice. This study aims to explore and evaluate the Zn and Fe content of local rice genotypes from West Sumatra, which hold potential for biofortification programs.Twenty-eight rice genotypes, including 27 local genotypes and one control (Inpari Nutri Zinc), were analyzed for Zn and Fe content. The results showed that the control variety, Inpari Nutri Zinc, exhibited the highest Zn (31.30 ppm) and Fe (19.85 ppm) content. Among the local genotypes, Puluik Mutia (Zn: 28.40 ppm, Fe: 18.30 ppm), Kuning Aro (Zn: 27.60 ppm, Fe: 18.20 ppm), and Rampai Kuning (Zn: 26.20 ppm, Fe: 18.05 ppm) displayed the highest Zn levels, while Manggung (Fe: 18.85 ppm) had the highest Fe content. These findings highlight the significant variability in micronutrient content among local genotypes, emphasizing their potential as germplasm for biofortification breeding programs.This research represents the first systematic exploration of Zn and Fe levels in local rice genotypes from West Sumatra. The novelty lies in identifying high-Zn and Fe genotypes, particularly those with firm texture preferences, which could support biofortification efforts and provide a sustainable solution to combat stunting. Future research should focus on environmental interactions and agronomic practices to further optimize the micronutrient content in local rice varieties

Abstract

Enhancing wheat productivity and grain quality is a strategic agricultural goal, particularly under conditions of increasing population pressure, soil degradation, and climate variability. Winter soft wheat varieties, especially during the reproductive development phase, require additional nutrient inputs beyond what root systems can supply. Foliar application of nutrients like urea during the full heading (earing) phase has emerged as a cost-effective agronomic solution. Although foliar feeding is acknowledged for its efficiency, there remains a lack of consensus on the optimal application rates, particularly under irrigated conditions and across different wheat varieties.This study aimed to assess the effect of foliar-applied urea at different rates on the 1000-grain weight of Yaksart and Gazgan winter wheat varieties. Field experiments conducted from 2015 to 2017 revealed that a 40 kg/ha urea solution applied through foliar feeding during the full heading phase resulted in the highest increase in 1000-grain weight—up to 2.8 g in Yaksart and 2.7 g in Gazgan—compared to control groups. Lower or higher dosages (30 and 50 kg/ha) were comparatively less effective. The findings identify a precise and optimal rate of urea application for enhancing grain weight during a critical growth phase, based on multi-year, replicated trials under local agro-climatic conditions. This study provides actionable recommendations for wheat farmers to improve grain yield quality via targeted foliar nutrition. Future research may explore the physiological mechanisms involved and test scalability under diverse soil types and climatic zones.

Abstract

Upright Beans (Phaseolus vulgaris. L) are one type of horticultural commodity that has great potential to be developed, but recently bean production has decreased. One of the causes is the presence of weeds that can cause competition in fighting for life's necessities. Therefore, control measures need to be taken by weeding. The purpose of this study was to determine the right weeding frequency to increase the growth and yield of upright bean plants. The study was arranged in a Randomized Block Design which was repeated 3 times. The research data were analyzed using the F test method at 5% level and followed by DMRT at 5% level. The results showed that the frequency of weeding at 21 HST gave the best results for plant height of 212.59 cm and the frequency of weeding carried out at 14 HST gave the best results for the parameters of the number of pods per plant of 14.90 and the weight of pods per plant of 129.63 g.

Abstract

This study aims to analyze the effect of production land area on the income of coffee farmers in Pargarutan Jae Village, South Tapanuli Selatan. The method used is a quantitative approach involving 109 coffee farmer respondents selected using the accidental sampling method. Data were collected through questionnaires, observations, and documentation, then analyzed using Structural Equation Modeling Partial Least Square (SEM PLS). The results show that the production land area has a significant influence on increasing coffee production, which in turn positively impacts farmers’ income. The majority of farmers have a last education level of vocational high school/general senior high school and are in productive age, with most incomes at the lower-middle level. The validity and reliability of the research instruments have been well tested, with loading factor and AVE values meeting the criteria for convergent and discriminant validity. These findings indicate that managing and increasing the production land area is a key factor in improving the welfare of coffee farmers in the area.

Abstract

This study aims to analyze the mediation effect of land area on the relationship between price and productivity on oil palm farmers’ income in Bangko Pusako District, Rokan Hilir Regency. A quantitative approach using Structural Equation Modeling-Partial Least Squares (SEM-PLS) method was employed to analyze data from 155 oil palm farmers selected through accidental sampling technique. The results show that palm oil prices and productivity do not have significant direct effects on farmers’ income. However, land area proves to have a significant direct effect on farmers’ income (T-statistic = 2.208, p-value = 0.028). Mediation analysis reveals that palm oil prices significantly affect income through land area mediation (T-statistic = 2.112, p-value = 0.035), while productivity does not significantly affect income through land area mediation (T-statistic = 1.611, p-value = 0.108). These findings confirm the important role of economies of scale in oil palm farming, where farmers with large land areas have comparative advantages in utilizing market price fluctuations. This research provides theoretical contributions to the development of farmer income analysis models and practical inputs for formulating more effective and targeted oil palm farmer empowerment policies.

Abstract

A field experiment was conducted during the winter season of 2023–2024 in Salah Al-Din Governorate (central Iraq) to investigate the effect of soil type (loamy versus gypsiferous soils with 20% and 30% gypsum content) and foliar application of dill extract (100 ml L-1) on the growth and productivity of faba bean (Vicia faba L.). A completely randomized design (CRD) with three replications was employed, comprising a total of 12 experimental units. The results demonstrated that foliar application of dill extract at 100 ml L-1 significantly improved all studied traits compared to the control (without application). In loamy soil, the highest values were recorded for plant height (110.4 cm), root length (30.2 cm), pod length (25.2 cm), number of leaves (85 leaves plant-1), number of pods (11 pods plant-1), and number of seeds (7 seeds plant-1). In contrast, these parameters were markedly lower in the gypsiferous soils (20% and 30% gypsum content). Furthermore, loamy soil outperformed the gypsiferous soils across all indicators, confirming the decisive role of soil type in faba bean productivity. The study highlights that applying dill extract at a concentration of 100 ml L-1 in loamy soils represents a promising strategy to enhance the growth of faba bean, especially in areas with mixed or gypsiferous soils.

Abstract

This study took a close look at different types of corn plants (Zea mays L.) to see how well they stood up against the corn stem borer, Sesamia cretica. We also explored how applying potassium to the leaves affected their resistance. The experiment happened during the summer growing season of 2024 at the University of Kirkuk's Agricultural Research and Experiment Station. We used a standard experimental setup, repeating our tests three times. We tried three different potassium concentrations (0, 15, and 30 grams per liter) and tested six distinct corn varieties: KONSENS, DKC777, DKC666, AGN720, GAMESON, and GOLDEN. We measured several things: how much the plants got infected, the number of holes, larvae, and tunnels in each plant, and how much of the stem was eaten away. Our statistical analysis showed that both the potassium application and the type of corn plant, as well as their combination, had a big impact on most of the traits we measured. The only exceptions were the infection rate, the number of larvae, and the excavated distance when considering the interaction between the plant type and potassium. Interestingly, the 'GAMESON' corn variety consistently showed the best resistance. It had the lowest infection rate (15.94%), the fewest holes (5.31), larvae (1.51), tunnels (2.18), and the least stem damage (17.36%). Applying potassium at 30 grams per liter also significantly helped, reducing the infection rate to 16.38%, holes to 2.73, tunnels to 2.52, and stem damage to 16.80%. The best results came from combining the 'GAMESON' variety with the 30 gm/L potassium treatment, leading to the absolute minimum number of holes (1.86) and tunnels (1.46). This really highlights how much this combination boosts resistance. Our findings strongly suggest that using resistant corn varieties like 'GAMESON' along with smart potassium fertilization can significantly protect corn crops from the stem borer.
