| To investigate the effect of soil additives in reducing the effect of water deficit stress on sugar beet, an experiment was performed as a combined analysis in two regions based on randomized complete block design with four replications. Experimental treatments were location factor at two levels of Miandoab and Malekan, water deficit stress factor at three levels of 50 mm (Lack of stress), 110 mm (moderate stress) and 170 mm (severe stress) evaporation from class A evaporation pan and soil additive factor at four levels of control (no soil additives), superabsorbent, mycorrhiza and livestock manure. In the present study, the use of soil additive treatments in both regions were able to improve the yield of pure sugar compared to control. In irrigation... |

| The crop land suitablity assessment (LSA) has importance for managing land and water resources and developing sustainable agricultural systems. In the field of determining the suitablity of crop land, the multi-criteria evaluation approach (MCEA) or multi-criteria decision-making (MCDM) is becoming more popular as a tool for analysing difficult situations and obtaining logical conclusions. The 75 relevant publications from 2010 to 2023 reviewed and summarised in this paper to precisely explain and identify MCEA application areas and decision-making problems resolved within the crop land suitablity assessment. The findings indicated that the MCDM or MCEA techiques have been applied with or without remote sensing or Agricultural Land Use Evaluation System,... |

| The growth and yield of green-leaf Romaine lettuce grown under a tropical greenhouse using the vertical aeroponic system with rootzone cooling were evaluated in this study. The experiment was set up using a Combined Analysis in Strip-Plot design in a 6m x 12m greenhouse wherein the two rootzone cooling methods, a ground heat exchanger (GHE) and improvised chiller, were the treatments while harvest periods of 20, 25, and 30 days after transplanting (DAT) were the horizontal factors, and the levels of the tower (top, middle and bottom) were the vertical factors. The IRRI-Statistical Tool for Agricultural Research (STAR) was used for data analysis. Results revealed that longer and broader leaves and higher yield were observed using the improvised... |

| Considering the need for threshing the current energy crisis, the power potential of solar energy, especially, many stand-alone solar installations in rural areas, and their use, a study was undertaken to develop and evaluate a solar-powered multicrop thresher under various seasons of the year on soybean. The study was conducted in IARI-New Delhi, aiming to assess the seasonal suitability of the solar operated thresher. The devolved prototype was evaluated on soybean crops, and the results were used to optimize the operational and machine parameters by Response Surface Methodology (RSM), with Central Composite Design (CCD). Four independent parameters, each at three levels, were taken viz. feed rate, cylinder speed, concave clearance, and spike types to... |

| The factors influencing on seed germination and wheat yield are such as the optimum use of tillage and seeding methods. This study was a randomized complete block experimental design with four treatments and four replications to determine the suitable tillage method for a grain drill with bent leg opener (bent leg grain drill) and also determine the effect of these implements on soil moisture conservation and rainfed wheat yield in dry soil conditions. Treatments were seeding wheat by a bent leg grain drill in four tillage application of direct seeding (no-tillage), bent leg tillage (reduced tillage), bent leg tillage + disc (reduced tillage), and chisel plough + disc (conventional tillage). Results indicated that tillage... |

| This paper introduces a cheap local Ricinus communis, which grows in Jahrom, a warm region of southwest Iran, as a renewable energy source. Biodiesel production was investigated by employing CaO and C:CaO as heterogeneous catalysts and KOH as a homogenous catalyst. Conventional and ultrasonic-assisted methods were used considering different methanol to oil molar ratios (4:1, 6:1 and 8:1) and different temperatures (40 ˚C, 50 ˚C and 60 ˚C). The optimized production condition was assessed by response surface methodology (RSM). The results showed that the most suitable catalyst was C:CaO with a methanol to oil molar ratio of 6:1 and temperature of 60 ˚C. Using carbon with CaO increased biodiesel yield by around 20% compared to CaO alone. In all conditions,... |

| The concept of "Smart Farming" integrates fuzzy logic, a form of artificial intelligence, to manage control systems in an adaptive manner, similar to human decision-making under uncertain conditions. The cooperative operation of sensors measuring humidity, temperature, and irrigation systems ensures the most favorable conditions for plant growth. The researchers designed the experiment as follows: Group A: Newly planted durian trees grown using IoT technology inside a greenhouse. They are irrigated using Fuzzy Logic-controlled sprinklers, and the temperature is regulated through mist spray. Group B: Newly planted durian trees grown using IoT... |

| Crop yield prediction plays a key role in modern agriculture, it enables farmers to make decisions about resource distribution, crop production management, and marketing business strategies. Regression models are extensively used for crop yield prediction. The performance of different regression techniques may vary depending on various factors such as the dataset, features, and modeling assumptions. In this paper, Author conducted a comparative study to evaluate and compare the performance of different regression models for agriculture crop yield prediction. Collected a comprehensive dataset encompassing historical crop yield data, weather parameters and pesticides data features from various agricultural regions, then applied and... |

| The transportation of fresh agricultural material is a challenging task that can lead to considerable losses due to vibrations and shock stresses. This study reviews 55 articles published between 1985 and 2023 to gain insights into the impact of these factors on the damage of agricultural material. The review reveals several factors that affect vibration levels during transportation, including the suspension system's type, truck speed, road profile, payload capacity, stack height, and packaging material. However, previous research has examined these factors independently, and their relative impact on the vibration intensity remains unclear. Therefore, we suggest a multi-factor assessment of transport vibration intensity to identify the most influential... |

| The pre-cooling process (The removal of field heat) is considered one of the most important post-harvest processes that directly affect the quality and production. Pre-cooling reduces microbial activity, respiration rates, and vital heat. This process reduces water loss and decomposition, thus, it helps to maintain quality and extend the shelf life of the fruits. This study aimed to provide the optimal design of a solar precooling system for small-scale producers. The working principle of the designed pre-cooling system was based on a solar energy system integrated with water cooling combined with indirect evaporative cooling. The total required time to reduce the water temperature from 25 to 15, 10, and 5 °C was 1.88, 2.63, and 3.4 hr,... |
