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:
In order to solve the problem of low efficiency in peeling green husks and long–term piling up of green almonds, a brush roller type almond peeling machine was designed in this study. Driven by three–phase power and under the effect of the belt and bucket elevator, green almonds were uniformly conveyed to the peeling chamber by a screw feeder, then the almonds are subject to the reverse action between the microcone extrusion device and the roller and the green peels were partially separated from husks. On this basis, the steel brushes would peel the almonds and remove the impurities. The physical parameters of green almonds and hard shell almonds were measured, and based on the values of the parameters, the main working parts of the device were designed and analyzed, and their main structural parameters and working parameters were determined. The software Design–Expert was applied to design a three–factor–three–level response surface test on the designed brush roller type almond peeling machine. Test results showed that, the optimal working parameters of the device were: rotating speed of the principal axis was 307.5 r/min, the gap was 20.1 mm, production rate was 811.5 kg/h, peeling rate was 96%, damage rate was 2.28%. The research results can provide reference to the improvement of performance of peeling machines and design of primary processing equipment of almonds.
A field experiment was conducted to investigate the potential of iodine biofortification in tomato fruits through fertilization of potassium iodate in soil, foliar form and chitosan complex forms. While foliar spray alone increases the iodine content in leaves, the chitosan iodate complex alone and soil application alone increased iodine content in roots and stems. However higher iodine accumulation in the tomato fruits was achieved through the combination of foliar and iodine chitosan forms, as electrostatic interaction between chitosan and iodate prevents volatilization and gradually increases the bioavailability of iodine from soil to fruits. The transfer factor was higher for iodate and chitosan complex from soil to plant. Further, the average and relative distribution of iodine in plants revealed that the chitosan iodate complex and foliar spray combination is proven to be the most effective, as it keeps adequate amounts of iodine in the roots, stems, and leaves while also increasing iodine content in the final fruit. Biofortifying iodine through iodate chitosan complex increases the iodine content in tomato fruit and introducing it in our daily diet may help to reduce iodine deficiency.
Energy is a primary driver of economic growth and welfare. Provision of good quality energy is a means to improve the standard of living of the people. Power scenario in the country which had worsened over the years with the deficit at 10.1 per cent and the peak deficit at 12.7 per cent during 2009-10 has now improved somewhat, with a recorded deficit of 0.7 and peak deficit of 2.0 percent in 2017-18 state of Rajasthan has 10 per cent of India’s land, 5 per cent of its population and only 1 per cent of its water resources, a disadvantage by a factor for supply of irrigation water vis-a-vis agriculture area. To estimate the present status of farm power availability across the states at District level from secondary sources were analysed and the farm power availability at district level has been calculated. The percent change in farm power availability during 2007-08 and 2017-18. The average farm power availability in the State of Rajasthan during 2007-08 was 0.932 kW/ha and it increased to 1.414 kW/ha by the end of 2017-18, thus registering a 51.72 % increase in FPA in last tn year due to increase of solarisation and implementation of Sub-Mission on Agricultural Mechanization. Acute water shortage, erratic rainfall and recurring droughts in every district have exacerbated the situation. The development of Rajasthan’s Agriculture depends on its technological changes i.e.a change in the parameter of production function resulting directly from the use of new knowledge.
Crop typing at cadastral level is considered as an important input for precision farming, farm management, crop water requirement, crop yield assessment, and crop insurance settlement among others. Advances in satellite remote sensing, Geographic Information System (GIS), classification algorithms, and computational infrastructure provided us the opportunity to classify and map crop types at cadastral level. However, it remains a question that, which particular method of classification is best for a given site? especially when it comes to map the crops at cadastral level using satellite data. The current work is an attempt to answer this question using a combination of five data types (including, optical, SAR, merged optical and SAR, time series optical, and time series SAR), and four popular classification algorithms (including Unsupervised k-mean, supervised Maximum likelihood (MXL), Support vector machine (SVM), and Random Forest (RF)). Results reveal that the time series of optical and microwave data performs better with random forest classifiers (over all accuracy ranging between 67 to 73% and Kappa coefficient ranging from 0.54 to 0.60) as compared to other combinations and classifiers, when a 100% accuracy check approach (new approach) was used. The most of the errors occur at the margin pixels due to mixing. The current finding is applicable for a large part of the nation corresponding to heterogeneous cropping, especially during monsoon season.
This research was undertaken to examine the effect of microwave dosage as pre-milling treatments on chickpea and pigeon pea dehulling to analyse the dehulling parameters. The experiments were conducted for pre-milling treatments of chickpea and pigeon pea at different microwave dosage range from 103.85 J/s to 560.77 J/s to evaluate dehulling parameters viz. surface temperature, dehulling yield, dhal yield, and dehulling loss. It was noted that the average surface temperature of chickpea increased from 56.3 to 132.11oC for chickpea and from 58.12 to 126.99ºC for pigeon pea, respectively, with increased microwave dosage in this range of microwave dosage. The highest dehulling yield, 71.02%, for chickpea was achieved at 207.69 J/s microwave dosage and 63.46% at 467.31 J/s microwave dosage and found maximum dhal yields, i.e., 66.40%, at 207.69 J/s for chickpea and 62.30% at 467.31 J/s for pigeon pea with a minimum dehulling loss 10.25% at 560.77 J/s for chickpea and 4.61% at 103.85 J/s for pigeon pea. Hence, microwave pre-milling treatment is recommended for continuous type pre-milling treatments with the dehulling operation to replace existing pre-milling methods and further develop one continuous type pre-milling treatment system in the pre-milling process; it also confers and gets attention over traditional one’s methods during pulse processing as non-chemical alternatives for commercial adoption in the near future.
