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:
A two-year field experiment was conducted to investigate the effect of leaf colour chart (LCC) and chlorophyll meter (SPAD meter) based nitrogen fertilization on nutrient uptake, use efficiency and productivity of wheat crop under irrigated sub tropics of Jammu. The investigation conducted at Divisional Research Farm of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus Chatha during Rabi 2018-19 and Rabi 2019-20. Experiment was laid out in randomized block design with four replications and six treatments viz. control, nitrogen application based on LCC ≤ 3, nitrogen application based on LCC ≤ 4, nitrogen application based on LCC ≤ 5, sufficiency index based nitrogen application and recommended dose of fertilizer (100:50:25:37.5 kg/ha N:P2O5:K2O:S) along with well fertilized reference plot with 150 per cent recommended dose of nitrogen (150:50:25:37.5 kg/ha N:P2O5:K2O:S) for calculating sufficiency index. Among different treatments of nitrogen management, significantly highest yield and nutrient uptake were recorded with LCC ≤ 5 based nitrogen application. However, sufficiency index based nitrogen application recorded numerically higher nitrogen use efficiency and apparent recovery of nitrogen whereas recommended dose of nitrogen application recorded maximum physiological efficiency.
The issue of food safety and food security are the two key aspects in our country. Also the food we consume is safer or not is the most important topic of concern now-days. In order to estimate the potential risks due to pesticide exposure from food, it is required to evaluate the level of exposure at the time of consumption. The aim of this study conducted during 2016-17, was to assess the level of Tebuconazole (Folicur 25.9EC @ 125 and 250 g a.iha−1) residues in chili fruit. Gas chromatography-tandem mass spectrometry (GC-MS / MS) was used to analyze collected samples. Residues dissipated with time showing a half-life of 1.61 days at a single dose and 2.19 days at double dose after kinetics of first order. The processing is very efficient in reducing tebuconazole residues in chili fruits. By washing with tap water, tebuconazole reduction ranged from 55.71 percent to 30 percent. While the percent reduction of residues on washing with NaCl solution was in the range of 72.38 to 33.33 percent. Results indicate that washing with NaCl solution as better household practice for reducing the residues in the chili fruits for consumption purpose.
Integrated management practices offer optimum use of land and farm resources through combination of various climate smart agricultural practices and other improved farming practices at common platform. However, there exists a major concern of their awareness level among farmers which ultimately leads to low level of adoption among the farmers particularly in situation like Haryana where small and marginal land holdings farmers are dominated. The data were collected from Haryana state of India with the help of well- structured and pre-tested interview schedule and analysed with Statistical Package for the Social Sciences. Research findings concluded that farmers awareness level was observed to be the highest about the INM increase the crop yield with weighted mean score (WMS) 2.02, excessive pesticides use is hazardous (2.03), weeds compete for light, water and nutrients (2.14), integrated farming system helps to reduce the cost of production (1.91), organic farming reduces input cost and enhances food quality (2.36), zero tillage reduce the field preparatory, labour and fuel costs (1.78), information and communication technologies provide information accurately, frequently and timely (1.64), e-marketing promote the cashless transaction (1.88), and crop insurance minimize the risk of crop failure (2.28). Hence, it is suggested that sincere efforts by government are required for promotion of such eco-friendly and sustainable practices in the country.
Wheat (Triticum aestivum) is an important cereal crop of the world. Major biotic stress on wheat yield is the weeds. Wheat growing areas are now suffering from deficiency of micronutrients. Field experiment was conducted at RRS, Bawal during Rabi season of 2018-19 to evaluate the post-emergence herbicidal combinations with Zn or/and Fe in wheat. Experiment consisted of 18 treatments replicated thrice, was laid out in Randomized Block Design. Four herbicidal combinations viz. clodinafop + metsulfuron @ 60 g/ha, sulfosulfuron + metsulfuron @ 32 g/ha, mesosulfuron + iodosulfuron @ 14.4 g/ha, pinoxaden + carfentrazone @ (50 + 20g/ha) were evaluated with Zn, Fe and with both Zn as well as Fe. Yield components as well as grain yield of wheat increased significantly under the influence of herbicidal treatments over weedy check. Addition of iron and zinc to the herbicidal combinations resulted into increase in yield components and grain yield of wheat. Application of combined (Zn + Fe) with herbicidal combinations enhanced the grain yield of wheat significantly over application of sole herbicidal combinations. Highest grain yield was obtained under the influence of mesosulfuron + iodosulfuron @ 14.4 g/ha + ZnSO4 (0.5 %) + urea (2.5 %) + FeSO4 (0.5 %).
The problems in fruit setting with artificial pollination (contact type) can be eradicated by the application of electrostatic forces (non – contact type), hence the study was undertaken to develop an electrostatic pollinator and tested for tomato under polyhouse condition. Morphological characteristics of these flowers were studied for design of pollinator. A high voltage amplification unit with flyback transformer and MOSFET, a spherical shaped electrode and a DC input source were the major components of the developed electrostatic pollinator. The pollen collection capacity of two electrodes E1 (10 mm) and E2 (7.5 mm) were evaluated at voltage potentials of 3 kV, 4 kV, 5 kV and 6 kV at 5 mm, 10 mm and 15 mm distance from the anther tip of flower. The maximum number of pollens (409) was collected by electrode E1 with a charging potential of 6 kV at 5 mm distance. This high pollen collection rate was due to high detaching forces acting on the pollen grains at shorter distance between the anther tip and electrode. The pollen collection capacity was minimum (87) for electrode E2 with an electrode potential of 3 kV at 15 mm distance.
