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 total of 360 day old straight run Vencobb broiler chicks were randomly allocated to six treatment groups with three replicates of 20 birds in each to study and compare the effect of chromium from three sources(inorganic, organic or nano) at two different dosage level on performance, and tissue accumulation in broiler chickens. The trial lasted for 6 weeks. The control group (T1) was given with the standard broiler diet while the other groups were supplemented with chromium(Cr) at 200 µg/kg (inorganic chromiumchloride-T2, organic chromiumpropionate (CrProp)-T3, chromiumpicolinate (CrPic)-T4 and nanochromium(nanoCr-T6) and 100 µg/kg (nanoCr-T5) diets. The results showed significantly increased body weight gain, decreased feed consumption and improved feed efficiency in nanoCr followed by organic and inorganic Cr supplemented groups. The Cr content in the plasma and liver was significantly increased by nanoCr followed by organic CrPic (200 µg/kg) supplemented groups while Cr in thigh muscle was increased by both nanoCr and organic CrPic (200 µg/kg) and that of breast muscle was increased by all Cr fed groups. It can be suggested that the addition of chromium to soya bean and maize diets improves the performance of broilers with increased plasma, liver and muscle tissue accumulation.
The present study was conducted to characterize the status of different farming systems and their impacts on the livelihood of farmers in Jammu. A total of 120 farmers were selected for multistage strategies, out of these 40 organics, 40 inorganic, and 40 integrated farming systems were selected from the study area based on different interventions. Descriptive statistics were derived and calculated for analyzing the socio-economic data. Propensity score matching (PSM) was applied with kernel matching and radius matching methods to assess the impact of organic, inorganic, and integrated farming on farmers’ employment creation and income generation. The results of the baseline survey revealed that out of 120 sample farmers were categorized as follows: landless (15%), marginal (18%) small (44%), medium (14%,) and large (9%), respectively. The highest employment duration for the male gender was 152.5man days/year from farming systems like Crop+ Livestock+ Poultry + Horticulture (C+L+P+H) under integrated farms and for organic and inorganic these values hoisted at 125.5 and 104.5man days /year. The highest returns were obtained from the pulse-mustard-wheat cropping system with a B: C ratio of 2.03 followed by the rice-maize-vegetable cropping system with a benefit: cost ratio of 1.97. The average calorie intake of food secure per household was 2910 kcal, 2793 kcal, and 2854 kcal for organic, inorganic, and integrated farming systems, respectively. To assess the livelihood pattern through the asset pentagon approach, net-worthy improvement was found based on different capitals of farm households practicing in organic, inorganic, and integrated farming. Based on different problems a constraint-facing index (CFI) was calculated to suggest policy recommendations.
A field experiment was conducted during the winter (rabi) seasons of 2014-15 and 2015-16 to investigate the effects of row orientation and cutting management on the growth, yield, and micro-environment of dual-purpose barley (Hordeum vulgare L.) in sandy loam soil with low organic carbon and available nitrogen, but high available phosphorus and potassium. The randomized block design included eight treatments with different combinations of row orientations (north-south, east-west, bi-directional) and broadcasting sowing methods, along with varying cutting management techniques. Each treatment was replicated four times. The results indicated that bi-directional sowing of single-purpose barley resulted in a significant increase in all growth and yield characteristics compared to other sowing methods. However, row orientation did not have a significant influence on the growth of dual-purpose barley. From the perspective of farmers, the bi-directional sowing method outperformed other directions and proved to be superior for dual-purpose cultivation of barley, providing both grain and fodder. This was evident from the superior benefit-cost ratio observed. Based on the findings, it is recommended that farmers consider adopting the bi-directional sowing method for barley cultivation to optimize the production of both grain and fodder. These results contribute to a better understanding of the impact of row orientation and cutting management on dual-purpose barley, enabling farmers to make informed decisions and promoting sustainable agricultural practices.
The Brown Plant Hopper (BPH) is a destructive insect pest that is exclusively a monophagous pest on rice plants in rice-growing regions worldwide. BPH populations have evolved into new biotypes, becoming highly destructive to rice crop production. To enhance host plant resistance against the virulent BPH biotypes, this study aimed to introduce major broad-spectrum resistant genes, namely Bph20 and Bph21, derived from IR71033-121-15B (derived from Oryza minuta), into the susceptible elite rice cultivar CO 51. Backcross Inbred Lines (BILs) at the BC2F3 stage, harbouring Bph20 and Bph21, were developed through crosses between CO 51/IR71033-121-15B. A total of twenty BILs, along with the parents and control lines, were screened using the Modified Bulk Seedling Test (MBST) in a replicated trial. The recurrent parent CO 51 displayed an average susceptibility score of 7.5 against the BPH biotype, whereas the BILs exhibited improved resistance compared to the recurrent parent. Among them, BIL #12-2-2-2, BIL #12-2-2-9, BIL #12-2-6-3, BIL #12-2-6-5, BIL #12-2-6-6 and BIL #12-2-6-7 consistently demonstrated resistant reactions with an average score of less than 5 against the BPH biotype. The yield per plant improved from 0.48% to 7.84% in BILs over the recurrent parent CO 51. BIL #12-2-6-6 was recorded as a 7.84% higher yield over recurrent parent CO 51 followed by BIL #12-2-6-3 (7.30%) and BIL #12-2-6-5 (6.53%). This study successfully stacked or introgressed the major broad-spectrum genes Bph20 and Bph21, resulting in highly resistant BILs against the BPH biotype.
Among the sustainable and more respectful alternative strategies for man and his environment, arbuscular mycorrhizal fungi are used to limit or reduce fertilizers constitutes a problem in terms of cost and damage to the environment and soil. This study evaluated the effects of chemical fertilization and native mycorrhizal fungi collected from palm grove rhizospheres on the growth of wheat (Triticum durum Desf). NPK fertilizers were applied at four levels (0, 25, 50, and 100%) with or without native AMF inoculation. Results of all studied parameters showed that 25% and 50% chemical fertilizer combined with AM fungi gave the best growth improvement in wheat plants compared to inoculation with AMF alone. The other treatments with 100% chemical fertilizer combined with native AMF showed a decreased effect and mycorrhizal colonization is reduced by about 40%. This suggests that the combined application of low levels of chemical fertilizer and AMF can increase wheat growth and yield more efficiently than the application of either alone. On the other hand, it will preserve the environment and soil health, so the use of native AMF has an interesting economic and environmental advantage.
