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:
The present study aimed to assess the spatial variability and mapping of micronutrients under the sugarcane growing block of the Sivagangai district using geostatistics and the Geographic Information System (GIS). Totally, 100 georeferenced surface samples (0-30 cm) were collected and analysed for soil physicochemical properties. Descriptive statistics showed that the variance values coefficient ranged from 7.32 to 49.83%. Geostatistical analysis was executed for mapping the soil fertility properties with aid of well-fitted semivariogram models. Through cross-validation techniques, the standardized root mean square error (RMSSE) was computed and utilized for good prediction of the model. Geostatistical analysis revealed exponential for pH, EC, Free CaCO3 and B, Circular model for OC and Zn, Spherical for Fe and Mn, and the Gaussian model fitted well for Cu. Multivariate statistics viz., Pearson’s correlation coefficient and stepwise multiple regression were carried out and results showed significant correlations and interrelationships among the soil parameters. The principal component analysis provides the four principal components (PC1, PC2, PC3, and PC4) pertain to eigenvalues > 1 and together elucidated 71.29% of the pattern variance. The kriged map of available Fe, Cu, Zn, Mn, and hot water-soluble B showed areas under deficiency of about 57.3, 52.2,50.2, 44.5, and 83.2%. The spatial variability of various parameters helps in site-specific soil nutrient management and crop planning decisions to enhance sugarcane productivity.
The eco-friendly farming utilizes most efficiently the traditional practices of crop rotations with legumes, tillage practices to improve soil texture, application of adequate organic matter to sustain, retain and release soil moisture, nutrient to match crop needs and correlation factors of soil ill health. The present study was conducted in Narmadapuaram district of Madhaya Pradesh with 120 respondents of 10 villages which were selected randomly. In the adoption of eco-friendly management practices by vegetable farmers, majority of the respondents (61.67%) were of medium adoption category, followed by 23.33 percent respondents with low adoption and only 15.00 percent respondents with high adoption of eco-friendly technologies. Correlation analysis showed that the vegetable farmers with high level of education, social participation, annual income and having subsidiary occupation along with farming were having more knowledge about eco-friendly management practices in comparison to those with lower level of above stated variables and having only farming as occupation.
Scale development and validation are critical to much of the work in the social, and behavioural sciences. For systematic and accurate measurement of impact of Transfer of Integrated Crop Management Technologies developed by MPKV Rahuri under Rashtriya Krishi Vikas Yojana (RKVY) on its beneficiaries the scale was constructed by following the  of summated ratings suggested by (citation) Edward. Out of the three phases, in the first phase 163 items were generated for covering all aspects of socio-economic impact of Transfer of Integrated Crop Management Technologies developed by M.P.K.V., Rahuri on beneficiaries collected from the various sources such as literatures, extension personnel’s, scientists from agricultural universities and experts from KVK’s. These were segregated under three sub-headings namely economic impact, social impact and agricultural impact and the validity of their content is assessed. In the second phase, the scale was constructed by item selection, pre-testing the questions, administering the survey, reducing the number of items, and understanding how many factors the scale captures. In item selection 163 items were sent to 100 judges comprising of senior faculties and experts in the field of agriculture. After analysis of relevancy preference score given by expert and were edited by following the 14 informal criteria suggested by . One hundred and thirty-three items having mean score value being equal to or higher than the overall mean score was selected for item analysis. These items selected through judge’s opinion were administered to a random sample of 30 farmers from non-sample area. The items are rated by the farmers on five-point continuum vis-a-vis strongly agree, agree, undecided, disagree, strongly disagree. Based on total individual score, the judges were arranged in descending order. Upper and lower 25 per cent of the judges were used as criteria groups to evaluate the individual statements. The critical ratio i.e., the t-value was calculated, and items were selected on the basis ‘t’ value equal to or greater than 1.75. Ninety-four items were selected after ‘t’ value calculation. In the third phase, we carried out scale evaluation, tested and checked the reliability the number of dimensions and their reliability and validity is assessed. The scale with 94 items thus developed was administrated to the 30 farmers who were neither previously interviewed nor had chance to come in the final sample. After period of 15 days the same 30 farmers undertook the test. Thus, we obtained two sets of scores with a very high correlation (r = 0.95) which indicated that the scale is highly reliable. The content validity of the scale was determined through a group of experts as suggested by  and it was ensured that items covered the various aspects of socio-economic impact.
Development of natural wood preservatives for the protection of wood against to the wood degrading agencies. Present investigation was designed to determine the feasibility of natural plant extracts on wood degradation and chemical constitute after decay test of Pinus roxburghii wood. During the study two plants species were selected for the wood preservation in this contest plant extract was extract with the help of two different solvent methanol and petroleum ether from the Acorus calamus and Parthenium hysterophorus. Wood samples treated with extract at various concentration (0.25%, 0.50%, 1.00%, 1.5%, 2%) and one control and exposed with white fungi (Trametes versicolor) for the three months. Treated wood samples show minimum (13.46%) degradation with methanol extract of P. hysterophorus and 13.63% degradation with petroleum ether of A. calamus treated wood sample and maximum degradation was noticed in untreated wood samples, degradation of wood sample was increase with decrease the plant extract concentration. At the same chemical properties of wood sample were also examine after decay test and find out that the maximum clod and hot water soluble extractives and alcohol benzene soluble extractives, lignin and holocellulose content were notice maximum in treated wood sample and decrease with decreasing in the plant extract concentration. Novelty of the study is selected plats show the antifungal property against to the fungi. It is help full in the wood preservation without effect the environmental health and human being.
This paper elaborates on the application of PV based quasi-Z-source Multilevel inverter(qZMLI) for the standalone system supplying AC loads. qZMLI is a preeminent topology that boost/buck the input voltage using shoot-through state and gained popularity due to its high reliability, low cost and compactness. This paper focuses on the design of the entire PV system interfaced with qZMLI. Determination of power consumption of loads, sizing of panels, sizing of inverter, sizing of battery and sizing of charge controller are elucidated alongwith calculations. The successful testing is carried out and the results are presented.
