AMA, Agricultural Mechanization in Asia, Africa and Latin America (ISSN: 00845841) is a peer-reviewed journal. The journal covers Agricultural and Biological Sciences and all sort of engineering topic. the journal's scopes are in the following fields but not limited to:
Pure and Safe water and sanitation facilities are the basic requirements for better hygiene and overall development of any society and community but still many communities are devoid of such basic needs. The overall situation is worst in developing countries in general and among the backward and tribal communities in particular. Therefore, it is the need of the hour to examine and investigate water, sanitation, and hygiene (WaSH) conditions for the empowerment of the Gujjar tribe that still practices transhumance. To explore WaSH conditions and enhance the empowerment of the tribe, WaSH Index (WI) and Empowerment in Wash Index (EWI) have been proposed in this research work by using a set of suitable indicators from four clusters of dwellings of this tribe. Unfortunately, none of the clusters was found to have an acceptable level of WaSH score. All the selected clusters were reported to have WaSH scores between 5.8 and 6.0. The study further revealed that only 18.5% of households were having better WaSH scores, whereas 34% of households were having poor WaSH scores. The poor WaSH score in alliance with the poor EWI score is largely attributed to (or controlled by) the quality of occupation, educational status, and household type. The present study revealed that 37% of the sampled households in the four clusters were found to be below the poverty line and involved only in primary occupations. The present study will have a broader implication for policymakers and tribal activists in meeting the goals to achieve an acceptable level of WaSH score among the tribe.
Beauveria bassiana (Balsamo) Vuillemin is a promising entomopathogenic fungus used as a biological pesticide that mycosis a wide range of arthropod hosts. In agricultural fields, a significant amount of agricultural waste is generated. Laboratory studies on the combination of botanicals and entomopathogenic fungi, as well as their compatibility, could provide useful information for the development of pest management strategies in organic agriculture. Therefore, efforts were made in this study to grow the B. bassiana on agricultural wastes for spore production and to determine B. bassiana compatibility with botanicals that are alternatives to synthetic chemical insecticides. Among the substrates tested, chopped potato slice resulted in significantly highest spore production of test fungus as support the maximum production of spore load (4.3× 108 cfu/gm) followed by rice (4.1× 108 cfu/gm) whereas sawdust supported least spore load than other substrates on 25th DAI. In vitro, nine different botanicals were tested against B. bassiana at a concentration of 10%. The maximum radial mycelial growth was observed in Eucalyptus globulus (5.08 cm), with the percent growth inhibition (43.66%), whereas the botanicals were Azadirachta indica (72.0%) and Prospis juliflora (70.55%) have an inhibitory effect on B. bassiana.
Roasting is a process of dry heat treatment which involves high temperature and short time which lead to an increase in characteristic aroma, colour and texture in the food grains. The present study was undertaken to investigate the effect of roasting on the physico-chemical properties and bioactive components of brown rice, oats and flaxseeds. The effect of roasting on physico-chemical properties (colour values viz., L*, a*, b*, moisture, protein, fat, fibre, ash content, carbohydrates and energy value) and bioactive components (total phenolic content and antioxidant activity) was evaluated. The changes in colour values were observed and it was found that the L* value of brown rice, oats and flaxseeds decreased from 56.23, 75.20 and 44.36 to 53.78, 69.63 and 33.15, respectively, whereas a* values increased after roasting. The bioactive components viz., total phenolic content and antioxidant activity became higher in roasted brown rice, oats and flaxseeds and the values for total phenolic content increased from 75.21 to 76.03 mg GAE/100g, 95.00 to 96.29 mg GAE/100g and 3.75 to 4.28 mg GAE/100g, respectively, whereas the values for antioxidant activities increased from 49.78 to 50.39 %, 14.28 to 15.86 % and 76.19 to 76.92 %, respectively for brown rice, oats and flaxseeds.
A self-propelled potato digger for small landholders was developed and evaluated. The developed prototype comprises of power transmission unit, digging unit, and separating/collecting unit of the self-propelled potato digger designed to address the needs of the hilly area. All the components were connected to a central support structure via nut bolts and welding, which was powered by a diesel engine (6.71 kW). The developed potato digger was evaluated at different machine and performance parameters. For all the treatment combinations, the maximum digging efficiency (95.37 percent) and the lowest damage percentage (3.24 percent) were observed at a treatment combination of forward speed of 2 kmh-1, rake angle of 260, and vibrating frequency of 900 rpm.
This work aims to improve the technical and economic performance of the ATESTA dryer by including a device with forced convection. This innovation aims to increase the quality of the dried mango and the dryer’s efficiency. For this purpose, a technical diagnosis of the ATESTA natural convection dryer has been carried out. The results of the technical diagnosis combined with a Functional Analysis (FA) and a Multicriteria Analysis (MCA) enabled the sizing of the device with forced convection integrated into the ventilation circuit. This new device comprises an air extractor, a potentiometer, and installation support. The performances of the ATESTA dryer with integrated forced convection compared to those of the ATESTA dryer with natural convection show a net improvement of 68 to 100% of the quality of the dried mangoes of 1st choice, a reduction of 40% of the drying time, of 34% of the consumption of butane gas; a 40% saving of the energy cost. Drying trials with the improved ATESTA gas dryer will be carried out on other tropical products (pineapple, papaya, etc.) to meet the needs of food processors in the West African sub-region.
