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:
Lactic acid bacteria are Generally Regarded As Safe (GRAS) and have long been used as natural biopreservatives. Lactic acid bacterial cultures were isolated from different fermented food samples viz., cumbu gruel, cold rice, milk fermented by green chilli, palmyrah fruit, mango pickle, sauerkraut and fermented finger millet and neera. They were screened for their antimicrobial activity against common food borne pathogens viz., Staphylococcus aureus, Pseudomonas aeruginosa and E.coli and spoilage organisms from spoiled potato, papaya, intestine of goat and hen and fish waste. Among the isolated cultures, cultures from cumbu gruel (CS and CT) exhibited the maximum antimicrobial activity. Out of twenty six fractions eluted for CS and CT, only three viz., CT-5, CT-7 and CS-2 exhibited maximum antimicrobial activity. These three fractions were further analysed in HPLC which distinguished CT-7 fraction with a discrete and unique peak. GC-MS analysis was done for this particular fraction of CT-7 and the compound was identified as hexadecanoic acid, methyl ester. 16S rRNA partial gene sequencing identified CS culture as Streptococcus thermophilus and CT culture as Lactobacillus coryniformis. Bioefficacy testing of CT metabolite showed that CT and CT+CS treated samples of papaya, raw fish, raw meat did not exhibit any spoilage. After 40 days, the potatoes started sprouting in the untreated control whereas potatoes treated with CT and CS+CT did not show any symptoms of sprouting and softening. The study concluded CT culture from fermented cumbu gruel as a potential candidate with antimicrobial activity against common food pathogens and food spoilage organisms, and could be effectively used as a food biopreservative for extended shelf life of foods.
Animal behavior is an important indicator of animal welfare evaluation, is the entry point of accurate poultry breeding, and for poultry farming, due to the small size of chickens and large breeding scale, automatic monitoring, especially individual monitoring has great difficulties, the realization of PLF of chicken farms is a difficult problem, in view of this problem, this paper proposes a method based on improving Faster R-CNN for individual behavior recognition of laying hens. The VGG16 in the Faster R-CNN object detection network was replaced with the ResNet50 network, and the RPN was improved, the number of proposals was reduced, the ROI increased, and the accuracy was improved, which could automatically identified the four basic behaviors of individual laying hens of standing, lying down, feeding and drinking. Simulate the construction of the living environment of laying hens in real state, collected videos of laying hens in natural state as input, divided the videos into pictures, and identify individual behaviors of 3200 pictures, and the recognition rates of standing, lying down, feeding and drinking water were 96.4%, 92%, 86.3% and 80.2%, respectively. At the same time, it can reduce the contact between farmers and chickens, and increase the safety of biological epidemic control.
In agro-ecosystem, biological control agents like parasitoids and predators are the best alternatives to the pesticides, several of which have been replaced by new chemistry. The newer insecticides are eco-friendly, economical, more selective, highly safe and compatible with several biocontrol agents. Keeping this view the present study was undertaken to assess the effect of acetamiprid on the adults of C. blackburni. Results indicated that the acetamiprid 20 SP had significant adverse effect on the mortality of adults and also adult emergence at higher doses (acetamiprid 20 SP at 80 and 40 g a.i./ha) whereas acetamiprid at 10 and 20 g a.i./ha were found to be safe compared to standard check, monocrotophos.
An experiment was conducted to evaluate the efficacy of physical, cultural, biological, antiviral and chemical management practices individually and integrated disease management against cassava mosaic disease during 2018-2020 under field conditions at Tapioca and Castor Research Station, Yethapur. Among the treatments, hot water treatment @ 520C for 20 minutes+ Yellow sticky trap @ 20 nos. /ac + Foliar spraying of Spirotetramat 150 OD @ 0.14g/ lit at 30 and 45 DAP has decreased cassava mosaic disease incidence (47.22 per cent), whitefly population (3.75 nos./leaf) and increased the tuber yield (52.23t/ha) compared to control.
An open top chamber experiment was conducted in Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore to know the effect of elevated Carbon dioxide (CO2) on plant growth, yield, yield attributes and nutrient uptake of rice and maize. Both the crops were grown under three Carbon dioxide levels viz., 376 µ mol mol-1 CO2 (C0), 550 µ mol mol-1 CO2 (C1) and 650 µ mol mol-1 CO2 (C2). Rice was grown in Irugur (S1) and Padugai (S2) soil series. Irugur soil series was clay loam in texture, taxonomically classified as Typic Ustropept. Padugai soil series was clayey in texture, taxonomically classified as Vertic Ustropept. Results revealed that plant growth parameters like plant height, number of tillers, yield attributes such as number of productive tillers, number of grains per panicle, number of filled grains per panicle, thousand grain weight, grain and straw yield were concomitantly increased from active tillering to harvesting stage. These parameters have high in 650 µ mol mol-1 CO2 than 376 µ mol mol-1 CO2. Padugai soil series recorded significantly higher plant growth parameters and yield attributes than Irugur soil series. Maize was grown in Palaviduthi (S1) and Periyanaickenpalayam (S2) soil series. Palaviduthi soil series was sandy 1oam in texture, taxonomically classified as Typic Rhodustalf. Periyanaickenpalayam series was sandy clay loam in texture, taxonomically classified as Vertic Ustropept. Among the soil series, Periyanaickenpalayam soil series (S2) recorded higher plant height, cob length, number of rows per cob, number of grains per cob, grain test weight, grain yield and stover yield compared to Palaviduthi soil series (S1). Comparison of CO2 levels indicated that, CO2 levels failed to attain the level of significance in growth and yield attributes. But, in both crops interaction between soil series and CO2 levels was failed to attain the level of significance.
