Performance Evaluation of Tractor-Mounted Garlic Planter
Agriculture assumes a crucial role in the economy and food security of Pakistan, as it generates substantial contributions to the Gross Domestic Product (GDP). In addition to prominent cash crops, a diverse range of vegetables and fruits, such as garlic, hold significant economic importance. Traditionally, garlic is sown using manual labor which results in wastage of cash and time. Therefore, there is a need for a mechanized solution for this problem. Although garlic planters have already been developed in Pakistan however performance of the planters has not been assessed in terms of draft force, planting efficiency, missing- and multiple-index and economic feasibility. In this study, performance of a 5-row tractor-mounted garlic planter, developed at Agricultural Mechanization Research Institute (AMRI), was experimentally assessed. According to the assessment results, maximum draft force of the planter was 5.0 kN and planting efficiency of the planter was relatively higher (i.e., 88% efficiency) at higher hopper capacity (i.e., 75% capacity). Additionally, missing was observed at lower hopper capacity (i.e., 25%) in terms of lesser number of plants in a line. Although, multiple-index was higher at higher hopper capacity (i.e., 75%) however the number of plants were also appreciably higher (up to 26 plants per line). The machine saved 10,350 PKR/acre with 62 hour/acre time saving when compared with the manual labor.
Use of Seismic Analysis as Analytical Tools in Soft Rock Tunnels – A Review
Tunnels have become an integral part of modern cities and metropolitan areas due to limited space and the rise in population growth in these areas. Data from past earthquakes have shown that tunnels are susceptible to severe/excessive deformation even though they perform better when compared to above ground structures. Seismic analysis of tunnels is important to evaluate how a tunnel will perform during earthquakes. In this work, numerical analysis and assessment of tunnels for seismic loading is conducted aiming to highlight the critical difference in the seismic performances. The geometrical configurations of the tunnel combined with the loading scenarios also significantly influence the magnitude and distribution of the seismic responses. The findings of this work shed light on the critical role of the geometrical configurations in the seismic responses of tunnels and this procedure can be applied as seismic assessment method to any tunnel shape, size and material.
STATUS OF THE RURAL TRIBAL YOUTHS OF INDIA TOWARDS AGRICULTURAL OCCUPATION -A Case Study of Mizoram State
Youth are disinterested in agriculture because of better opportunities in cities like better employment, better pay, or a more desirable job [2]. There are the clear signs that people were fast moving out from the agriculture, especially in the form of peasant migration, youth migration, occupational mobility in rural areas and rural youth practicing farming part- time and ageing of the farmer population in several pockets of the country. Currently, there is a challenge of retaining youngsters in agriculture due to various socio-economic factors, including profitability in agriculture pursuits. In order to assess the various factors attributing to distract youths from agriculture, a case study on the “Status of the Rural Tribal Youths of Mizoram towards Agricultural Occupation” was undertaken using multi-stage sampling technique with a total of 480 respondents from four districts of Mizoram. Data were collected through personal interview method by using a well-structured interview schedule. For analysis of data Frequency, percentage and co-efficient of correlation were applied. From the study it was found that the majority (58.33%) of the youth has no interest in agriculture and 72.91 per cent of youth were willing to shift from agriculture in search of other job and those who are involving in agriculture are also mostly part time(41.67%) before they get other job. The reasons ascertained by the youth is that agriculture brings low income, demands hard work, high risk and uncertainty, lack of government support, better technology and experience and not having agricultural insurance etc. The youths have a negative attitude towards agriculture considering that agriculture cannot fulfill youth’s socio-economic needs. It was observed that among twelve independent variables employment status, achievement motivation, membership in rural institutions were recorded positively significant and education and leisure time activity were found negatively significant. Hence, special efforts need to be taken up so as to attract, train and retain the rural youth towards agriculture farming as a whole by making it more economical, remunerative and profitable with scientific interventions as mode of taking agriculture as agribusiness enterprises. Policy implications such as imparting skilled oriented training, exposure to vocational courses, orientation in Organic and Natural farming, implementation of Integrated farming System, attracting to the agri-business potentiality, diversification in secondary agriculture, availing credit-linkage opportunities, creation & development of agricultural infrastructures and formation of FIGs, FCs, Clusters and FPOs can really benefit the overall socio-economic development and reviving of youths in agriculture professions.
Research on the Current Situation of the Grass-Root Practical Talent System of Agricultural Mechanization in Jiangsu Province and Related Countermeasures
The cultivation of practical talents in agricultural mechanization at the grass-root level is the core work of realizing agricultural modernization, which is of great value to promote the rural revitalization strategy. The work took Jiangsu Province as the research object and analyzed the current situation. The following problems were found, e.g., unreasonable talent structure, imperfect management mechanism, backward training concept, talent guarantee, and incentive atmosphere. Corresponding countermeasures proposed by investigating these problems can provide ideas and methods for enhancing the grass-root practical talent system of agricultural mechanization in Jiangsu Province.
Seasonal incidence of greater wax moth (Galleria mellonella L.) in Apis cerana colonies in relation to ecological conditions
The greater wax moth Galleria mellonella L. belonging to order Lepidoptera and family Pyralidae, is an economically important and most devastating pest of honey bees. It attacks all the species of Apis and cause a great economic loss to the beekeeping industry all over the world. Seasonal incidence of greater wax moth (Galleria mellonella) in Apis cerana in relation to weather parameters were conducted at A. cerana apiary maintained by Department of Entomology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during January 2019 to December 2020. Pooled data on greater wax moth incidence showed that the mean population of the greater wax moth arrayed from 0.83 to 8.97. Seasonal incidence of greater wax moth started in the month of February and the highest number of larvae, pupae and adults were recorded in the month of July (13.10, 9.10 and 4.70, respectively) when the temperature relative humidity and rainfall were high and after that population declined till November. Minimum incidence of wax moth population was observed in the month of February (1.20, 1.30, 0.00) and no incidence were found in the month of December and January when the temperature and rainfall were low. It was observed that weather conditions during summer and rainy period (May to September) were more favorable for greater wax moth development in A. cerana colonies. Wax moth population has a highly significant positive correlation with temperature. While the colony strength, brood area, relative humidity and rainfall has a positive non-significant correlation with wax moth incidence. Wax moth adults showed positive significant correlation with rainfall.
