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 comparison to the nations such as USA, Brazil, and China where the rates of agricultural mechanization are 95 percent, 75 percent, and 57 percent, respectively, India's rate of farm mechanization is comparably quite low (4–45 percent). Although, the efforts are being made to enhance the adoption of farm mechanization in India, but still the adoption is far away from an ideal level. It is a proven fact that farmers can gain from the introduction of a range of agricultural equipment. However, there are many factors that differentiate between use, adoption and possession of farm machinery. This paper studied the factors affecting the possession of light and heavy farm machinery in Jammu and Kashmir, India. Multistage random sampling technique was used to select 900 respondents from three zones; sub-tropical, intermediate and temperate of Jammu and Kashmir. The binary logistic regression model was applied to find out the factors affecting the possession of farm machinery. The probability of possessing light machinery is positively affected by factors such as livestock possession, unirrigated land holding, off farm source of income, and government employment, whereas the likelihood of possessing heavy farm machinery is positively affected by plain topography, family income, land holding, off farm income and self-employment. The innovative small farm tools alongwith light machinery need to be promoted in Jammu and Kashmir. The use of heavy machinery can be promoted through Custom Hiring Centres.
We aimed to compare underwater plasma discharge type boiler (Group 1) and conventional electric boiler (Group 2) for the heating energy saving in greenhouses. Two type boilers were installed in Zamioculcas zamiifolia growing greenhouse. As a result, the temperature differences from the set temperature were 2.1℃, 2.5℃ for Group 1 and Group 2. The water temperature difference of Group 1 was about 23~47℃ lower than Group 2, and the water temperature in Group 1 rose faster to the set temperature. The heating energy supplied to greenhouse tended to be high in Group 2, and there was no significant difference in the amount of heat loss according to heating methods. In addition, growth characteristics of Zamioculcas zamiifolia were investigated according to the heating methods, and leaf length, leaf width, tree height, and NDVI (Normalized difference vegetation index) were measured. As a result, it was confirmed that there is no significant difference according to the heating methods. Thus, we considered that the underwater plasma discharge type boiler can be used to heat greenhouse. The energy consumption were 5,051 kWh, 6,073 kWh for Group 1 and Group 2, so it was found that the underwater plasma discharge type boiler had about 17% heating cost saving effect.
Over the years, significant strides have been taken in harnessing solar energy for agricultural applications. Researchers have progressed well beyond mere experimentation, delving into diverse methods of desalination. From its inception as a straightforward Humidification-Dehumidification (HD) process, desalination technology has evolved to encompass a variety of advanced procedures. This paper provides a comprehensive overview of the prevailing desalination techniques, aiming to shed light on the technological advancements and breakthroughs within this domain. Additionally, we critically evaluate the primary advantages and limitations associated with these desalination methods.
To investigate the effects of weed management practices on the dynamics of the weeds, the WCE, the WI, and the performance of Indian mustard [Brassica juncea (L.) Czern & Cosson] during the Rabi season 2017-18, an experiment was conducted at the Narendra Deva University of Agriculture and Technology's Agronomy Research Farm in Kumarganj, Ayodhya. The experiment comprised of nine treatments, viz., T1-weedy check; T2-one hand weeding at 30 DAS; T3-two hand weeding at 20 and 40 DAS; T4-Pendimethalin (PE) 1.00 ai kg ha-1 ; T5-Oxyflorafen (PE) 1.00 ai kg ha-1; T6-Isoproturan (PE) 1.00 ai kg ha-1; T7-Pendimethalin (PE) 1.00 ai kg ha-1 + One-handed weeding at 30 DAS; T8-Oxyflorafen (PE) 1.00 ai kg ha-1+ One-handed weeding at 30 DAS and T9-Isoproturan (PE) 1.00 ai kg ha-1+ One-handed weeding at 30 DAS was evaluated in a Randomized Block Design with three replications. In the results of this study, we found that the crop was infested with five different kinds of weed flora. Among these were Phalaris minor and Cynodon dactylon which were the dominant grass weeds. In total, 26.7% of the total weed flora of the region was composed of broadleaved weeds (C. album and Anagallis arvensis). In the total weed flora of the park, the sedge (Cyperus rotandus) constituted 26.7% of the total weed flora, followed by other weeds. A variety of weed management practices were tested. Under treatment involving two-hand weeding at 20 and 40 DAS, weed index (WI), weed intensity reduction, dry matter reduction, and nitrogen uptake were found to be the best weed control efficiency, weed index (WI), and weed reduction. Pendimethalin (PE) was applied at 1.00 kg/ha plus one hand weeding was done at 30 DAS. It is therefore possible to conclude that weeding with both hands at 20 and 40 days of acorn cultivation and fallowing with pendimethalin (PE) @ 1.00 kg/ha together with one-handed weeding at 30 days of acorn cultivation may be a better approach to reduce weed density in mustard crops and to improve their productivity.
Vermicomposting, an eco-friendly waste management approach utilizing earthworms to transform organic waste into nutrient-rich compost, offers distinct advantages over conventional composting methodologies. Nevertheless, the comprehensive evaluation of diverse earthworm species, particularly exotic and indigenous variants, in vermicomposting processes remains relatively limited within the existing literature. In this study, we aimed to bridge this knowledge gap by scrutinizing the decomposition kinetics, nutrient profiles, and overall compost quality of two exotic species (Eudrilus eugeniae and Eisenia fetida) alongside one indigenous species (Drawida nepalensis). Our findings reveal discernible variations among the earthworm species in terms of maturation durations, bulk density, pH levels, total organic carbon, total nitrogen, total phosphorus, total potassium, total calcium, total magnesium, dehydrogenase activity, and urease activity. Remarkably, Eisenia fetida exhibited superior performance relative to the other species by significantly reducing total organic carbon content, augmenting nutrient concentrations, and enhancing enzymatic activity. These outcomes underscore the substantial influence of earthworm species selection on the resultant quality and composition of vermicompost. The insights derived from this research have significant implications for advancing environmentally sound waste management practices and enhancing our understanding of the role played by diverse earthworm species in the vermicomposting process.
