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.
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.
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.
While agricultural engineers are concerned with physico-mechanical properties of arable soils, agronomists tackle crop management husbandry as soil scientists’ dwell on bio-chemical properties. Such diverse and isolated interests seldom report any interaction or integrated effect of biological, agronomical, and physico-mechanical parameters of soils affected by mechanized tillage induced compaction. This paper reviews intrinsic effects of mechanized tillage-induced compaction on soil-water-nutrient dynamics, crop growth, and yield of maize. Mechanized tillage induced top and subsoil compaction are caused by soil-tyre contact stresses and machinery axle loads respectively. Mechanized tillage-induced compaction reduced maize nutrient absorption levels of Nitrogen (N), Potassium (K), Magnesium (Mg), and Sodium (Na) by 13.5%, 51.4%, 50.4% and 51.5% respectively. Maize N uptake was least affected by tillage-induced compaction compared to P and K. Mechanized tillage-induced compaction improved maize root intensity, root mass and volume by over 50% in compacted topsoils but decreased by 90% in the sublayers. Maize root length, fresh and dry root mass, shoot elongation, height, and leaf area index reduced by 29%, 39.1, 37.8, 27.1, 10-21, and 67.8% respectively. In contrast, mechanized tillage-induced compaction improved soil-seed-soil-root contacts, soil-root-bonding root density and diameter, stiffness, anchorage, and root-lodging resistance of maize. Mechanized tillage induced compaction index and bulk density range of 1.5-3.0MPa and 1.2-1.52 Mg/m3 respectively are the critical levels beyond which maize rooting, growth and yield are impaired. Dependent on dynamic soil covariates, viz limiting water range, matrix suction potential and organic matter content; mechanized tillage-induced compaction reduces maize yield by as high as 50%.
The improper usage of rice straw damages the ecosystem and injects greenhouse gases into the atmosphere. The purpose of this study was to increase water productivity by recycling this enormous quantity of agricultural biomass using microbial inoculants to break it down. The present study consists of three irrigation and seven nutrient management treatments viz., Continuous flooding (CON), Flooding with early and mid season drying (EMD), Irrigation as per SRI system (SRI) were assigned to main plot. Whereas, Nutrient management (NM) viz., Rice raw straw incorporation + 100% RDF (SF1), Rice raw straw incorporation + 75% RDF + 2% Urea foliar spray (twice) (SF2), Rice raw straw incorporation with Pusa Decomposer Capsules + 100% RDF (SF1D), Rice raw straw incorporation with Pusa Decomposer Capsules + 75% RDF + 2% Urea foliar spray (twice) (SF2D), Rice raw straw incorporation with TNAU Biomineralizer + 100% RDF (SF1B), Rice raw straw incorporation with TNAU Biomineralizer + 75% RDF + 2% Urea foliar spray (twice) (SF2B), 100% RDF (F1) were allocated to sub-plot. The outcome of the study revealed that irrigation as per SRI system (SRI) significantly recorded higher WUE of 7.32 kg ha-1 mm-1 in kharif 2021 and 6.35 kg ha-1 mm-1 in summer 2022. Concerning nutrient management practices, rice raw straw incorporation with pusa decomposer capsules + 100% RDF (SF1D) recorded marked influence with the highest WUE of 6.46 in kharif 2021 and 5.41 kg ha-1 mm-1 in summer 2022.
