| Basil is a popular aromatic and annual herb growing in many regions of the world. Immediately after its harvesting, the highly perishable raw material, i.e. leaves, have to be preserved against deterioration and spoilage. More often, during peak period, most of the crop is lost/wasted due to lack of proper post-harvest processing techniques. Drying is by far the most widely used treatment, which needs to be performed very carefully and preciously so as to preserve the aroma and color of the leaves. Various drying treatments and experimental methods viz., solar drying, tray drying, vacuum drying and fluidized bed drying were carried out at the temperatures of45°C,55°Cand65°Cto find and suggest the optimum drying condition for acquiring quality dried... |

| Abstract: The environment and resultant discomfort has severe impact on overall working efficiency of human and machine while using farm tools and machinery in hills. The Ladakh region of Jammu and Kashmir State of India is predominantly hilly. Anthropometric data of agricultural workers is very essential for the safe and efficient design of farm machinery. In the present studies, an anthropometric survey was carried out for agricultural workers of Ladakh region, wherein 90 male and female agricultural workers were selected and 79 body dimensions were precisely measured and recorded from each subject, thereafter analysed statistically. For making the data comprehensive and more useful, a set of 23 body dimensions, which are having direct implications... |

| This paper presents, assessment of cost-benefit parameters of conservation agricultural machinery for custom hires entrepreneurship development in southern region of Bangladesh. The key principles of the study were to determine the economic parameters for developing a CA (conservation agriculture) machine custom hire entrepreneurship and effective schedules for CA machine operation. Field experiments were conducted at Dumuria, Wazirpur, Subarnachar and Kolapara Upazila (Sub-district) of Khulna, Barishal, Noakhali and Patuakhali districts, respectively in the southern region of Bangladesh in the years 2017 and 2018. Two villages in each Upazila were selected for this study. Primary data was collected from these field experiments. Secondary data from various... |

| An activated carbon-supported sulfonic acid catalyst was synthesized and employed as a hydrolysis agent for hydrolysis of model and real biomasses including cellulose, starch, cellobiose, and switchgrass. Model biomasses including cellulose, starch, and cellobiose were hydrolyzed at 90 0C for 6 and 24 h while switchgrass was hydrolyzed at 75 and 90 0C for 6, 12, 18 and 24 h. For model biomasses, highest glucose was produced from cellobiose corresponding to 237. 1 ± 0.86 mg g-1 after 24 h, whereas switchgrass yielded a maximum glucose of 72.67 ± 1.03 mg g-1 after 18 h at 90 0C. In addition, effects of physical (ultrasonication) and chemical (NaOH and H2SO4) treatments prior to hydrolysis of switchgrass were also studied. The data suggested that physical... |

| Purchasing and maintaining agricultural machines are two of the most considerable costs of the agricultural sector, which includes farm equipment manufacturers, farm contractors and farms. In this context, repair and maintenance costs (R&M costs) generally constitute 10%-15% of the total costs related to agricultural equipment and tend to increase with the age of the equipment; hence, an important consideration in farm management is the optimal time for equipment replacement. R&M cost estimation models, calculated as a function of accumulated working hours, are usually developed by ASAE/ASABE for the agricultural situation in the United States, which is considerably different than agricultural context of other countries. So, the goal of this... |

| A 14.4 × 86.0 × 70.0 cm mud evaporative cooler was designed and constructed for the storage of sweet potato roots to evaluate its performance in storing orange fleshed sweet potato variety (Apomuden) roots. The investigation lasted for 14 weeks, from November 2014 to February, 2015. The dry bulb (Tdb) and wet bulb temperatures (Twb) for the ambient storage ranged between 27.600C to 26.900C and 22.500C to 20.100C respectively with their corresponding RH of 64.00%, 77.00% respectively, while Tdb and Twb within the cooler ranged between 25.940C to 24.860C and 21.940C to 20.610C with corresponding R.H of 89.00% to 92.00% respectively. The efficiency of the constructed evaporative cooler was 87.17%. From an initial weight of 2000 g, roots weight decreased to... |
