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 study was carried out during Rabi (winter) season of 2017-18 and 2018-19 at Research Farm, CCSHAU Regional Research Station, Bawal, India to find out cost effective weed management technique through mechanized interculture in chickpea with modifications in row spacing. The experiment consisted to nine treatments and laid out in randomized block design replicated thrice. The crop was infested with Chenopodium album, Chenopodium murale, Anagallis arvensis, Phalaris minor etc. Two mechanized interculture with tractor drawn cultivator 30 and 60 DAS under 60 cm row sopacing was found cost effective and more profitable seed yield of 1.65t/ha, and 26 % lesser cost of cultivation; 25 % higher net returns; and B:C ratio of 2.14 compared to the recommended manual interculture with Kasola at 25-30 and 45-50 DAS under 45cm row spacing over two years (2017-18 and 2018 -19). WCE of two mechanized interculture with tractor drawn cultivator or power weeder ranged from 59-63 % in comparison with 70 % observed under recommended two interculture with Kasola. Uncontrolled weeds throughout the crop season caused yield loss of 53 % over study period.
Sesame is important oilseed crop growing under light and drained soil for the oil and medicinal purpose. Stem and root rot caused maximum losses under sesame growing area and management is too difficult because of soil borne nature of the pathogen. Ten isolates collected from major sesame growing area of Rajasthan in which, all the isolates were significantly pathogenic on sesame tested on highly susceptible variety VRI-1 and produced typical symptoms. Among all the isolates, MPjd1 showed higher per cent disease incidence (56.00%) with minimum germination per cent (86.67%) of sesame seed tested against stem and root rot disease followed by MPjd2 (49.23%) disease incidence. Initial symptoms occurred within 26 days after sowing and found maximum pre emergence mortality with MPjd1 isolate. Twenty five entries of sesame were screened under field condition against stem and root rot and found that the none of variety or germplasm was recorded free from disease and categorized as immune or resistant. Only seven varieties namely RT-54, RT- 103, RT- 125, RT- 127, RT-351, RT- 346 and TKG- 306 were found moderately resistant.
This study was conducted in Imphal West district of Manipur so as to assess the impact of the ICAR-Participatory Seed Production (PSP) on the income of the small-holder farmers who have been producing quality seeds of rice. Altogether 50 farmers who cultivates ICAR most popular rice varieties (RC-Maniphou-12; RC-maniphou-13 and RC-maniphou-7) were selected for the study using purposive sampling technique. The study incorporates both the participating farmers and the implementing agency (ICAR) so as to take the complete information for analysis of the data. The study reveals that the participating farmers perceived the knowledge of the quality seed production and it is also found that the implementing agency has imparted the complete package and practices of seed production along with the necessary seed certification modalities. With the use of the ICAR varieties (RC-Maniphou-7; RC-Maniphou-12 and RC-Maniphou-13), it is also found that the yield of the rice increases by 37.5 %; 28.5 % and 62.5 % respectively as compared to the yield of the local cultivars and conventional rice production system. The results also show that 22% of the participating farmers have cultivated and produced quality rice seeds in both the pre-kharif and kharif season. 82% of the farmers’ reveals that their incomes have been increased almost by doubled whereas 18% have realized more than 50%. It is also found that almost all the seed producers can reduced their cost of cultivation upto 9 %. Lack of sufficient revolving fund for timely payment for buyback of seeds from farmers, high transportation charges and lack of manpower and storage facilities are the major constraints face by the implementing agencies whereas delayed payment for the seed, outbreak of major pests & diseases and natural calamities are the major problems encountered by the participating rice seed growers of the district.
A Field experiment was conducted to evaluate the residual effect of nutrient management on growth, yield attributes and yield of mungbean. The experiment was conducted in a Randomized Block Design (RBD) with 10 treatments and 4 replications during kharif, 2019 at Anand Agricultural University, Anand, Gujarat. All the nutrient management practices were followed in the previously sown pearlmillet crop. The Present experiment evaluates the residual effect of these nutrient management practices on mungbean. The residual effect of 100 % RDF + 15 t FYM ha-1 + Bio NP Consortia was recorded in plant height, number of pods per plant, test weight and protein content. The total number of nodules and the dry weight of nodules were significantly higher under the residual effect of 15 t FYM ha-1 + 5.0 t Vermicompost ha-1 + Bio NP Consortia (T10). The partial nutrient balance of the whole cropping system showed that nitrogen fertilization showed a positive balance, whereas phosphorus and potassium showed a negative nutrient balance under different nutrient management practices.
The study was conducted at Sagolkhong Watershed located in the Imphal west district of Manipur, India in the year 2018-19. A case study was done so as to analyze the impact of this watershed project on the income-employment and equity of the beneficiary households. For this, a two-stage-stratified random sampling method was used for the selection of three villages and 100 sample households from the Sagolkhong watershed using proportionate allocation random sampling technique. A preliminary survey preceded the actual survey by using well-prepared and pre-tested personal interview schedule so as to gain a firsthand knowledge of the various existing resources and other socio-economic features too. The primary objective of the study was to assess the employment, income generation and equity level of the project beneficiaries. Both conventional and mathematical tools were used for the analysis of the sample households. Also, the Gini concentration ratio & Lorentz curve for income distribution and equity were used for the analysis of the data. Due to the intensification of cropping pattern, adoption of various conservative measures and introduction of livestock sector, the sample households were provided ample room for giving employment. So, the per family employment level has significantly increased to 24 per cent. Hence, per hectare and per worker employment level have reduced to 1.5 and 3.7 per cent respectively after the project. With these, the average annual income of the beneficiaries households from both the farm and off-farm has significantly increased from Rs. 30050.61 to Rs. 41149 i.e. an increased of 36 per cent. This increased income has not been dispersed to the upper section of the community i.e., not to the richer fellows but also somewhat distributes among the weaker and poorer section too and particularly to the medium income group However, the increased income has not been evenly distributed to the marginal and landless farmers and is indicated by the Gini-Concentration ratio and Lorentz curve. The Gini- Concentration ratio before and after the project were found to be 0.38 to 0.36 respectively.
