Lack of information on the production and commercialization status of improved Panicum grass is one of the major livestock production impediments in South Omo. The improved Panicum grass is a perennial grass species used throughout the tropics for livestock feeding. Therefore, the present study was conducted to understand the seed and hay production status and the economic visibility of improved Panicum grass cultivation. The face-to-face interviews were conducted with improved Panicum grass producers. The quantitative data, such as the amount of bales and seed produced, and the qualitative data, such as agro-pastoralists’ perceptions, were analyzed using simple descriptive statistics and the Likert scale. The results revealed that the seed yield and herbage productivity after seed harvest were 2.5 quintals and 788 bales per hectare per cut, respectively. The average income generated from the sale of herbage and seed of Panicum grass was 325,350 ETB and 442,500 ETB per hectare per year, respectively. Based on the results, the authors concluded that joint efforts are needed to step the agro-pastoralists out of the poverty vicious cycle through promoting wide-scale improved Panicum grass production by linking products to market sources in addition to legumePanicum grass-based cattle and goat fattening intervention.

This study investigated barley output supply response determinant factors in Ethiopia. An ARDL bound test approach was employed as method using secondary data from 1981-2020. The study demonstrated that barley output supply was affected positively and significantly by zero-order lagged seasonal rainfall and crop growing period temperature. The study supports the findings of researchers who reported that warming temperature followed by an increase in the amount of rainfall had a positive impact on barley output supply. The positive impact of temperature was induced because of a rise in the ocean and earth’s surface average temperature, causing more evaporation that increases overall rainfall while reaching over the highland areas. Studies confirm that ENSO and moist winds coming from the Atlantic and Indian Oceans influence the occurrence of rainfall in the western, southeastern, central, and northern highlands of Ethiopia. The study further exhibited that CSMRR and CGPMT had a positive effect on barley output both in the long-run and short-run, implying that climate parameters have minimal effect on barley production. Nonclimatic variables demonstrated that both lagged and current year’s producer prices had a positively significant effect on barley output supply in both the long-run and short-run, implying that barley output supply is highly responsive to any price incentive strategies announced before re-allocation of the area towards barley cultivation. Conversely, the study explored that use of fertilizer in first-order lag had negatively significant impact on barley output supply in both seasons; implying that increased use of fertilizer in lagged period may reduce barley output as a result of inappropriate fertilizers application by farmers. The results generated by this study are useful addendum to the repository of knowledge on elasticity of crop supply at an aggregate level, which can be used in designing strategies and measures for mitigation and adaptation of climate change.

Korarima is a known cash crop in the South Omo zone and provides a wide range of economic and sociocultural benefits. Even though its economic and socio-cultural importance the development of the Korarima sector along with the value chain is hampered by several constraints. Hence, the study aimed to analyze the Korarima value chain in the South Omo zone. Using a two-stage sampling technique, 120 Kororima producers were selected to collect primary data through structured questionnaires. Descriptive statistics and econometrics model (multivariate probit model) were used for data analysis. The study identified three major Korarima market outlet choices such as collectors, retailers, and wholesalers as alternatives to Korarima producers to sell the majority of their products. Thus, collectors accounted for 82.2%, wholesalers (73.6%), and retailers (35.5%) of the total sold. The results of a multivariate probit model indicated that sex of household, credit access, family size, price information, market distance, and extension contact of farmers significantly affected the market outlet choice decisions in one or another way. Furthermore, no brand indicating this crop, inadequate infrastructural development, and market accessibility, weak extension services regarding improved varieties were major problems identified. Therefore, it is better to work on the brand name of this particular crop to trace up to the end market, infrastructural development and market accessibility, extension services provided regarding the improved Korarima variety, and accessing formal market information from the concerned body are essential to enhance Korarima producers’ benefit and bargaining power through avoiding information asymmetry.

This study summarises the main agricultural policies in Russia during 2014 and uses a sharp regression discontinuity design over time and data from the International Trade Centre to estimate the short-term effects of exchange rate liberalisation in November 2014 on import prices in Russian food markets. The sharp regression discontinuity design over time allowed an expost analysis of the short-term causal effects of the intervention on food import prices and distinguishing the effect of exchange rate liberalisation between product groups and from other interventions without using data from control regions, products and suppliers. Significant upward shifts in import prices were found for pig products, fish and cheese.

Bundelkhand region contributes more than half of total pulse area of the Uttar Pradesh state but the productivity is below the state average, which calls for various technological interventions, development of infrastructure and marketing strategies. This study assessed the profitability of pulse cultivation, identified the constraints and suggested policy measures using the data collected during 2016-2017 from 100 pulse growers selected from two backward districts of Bundelkhand region, namely Jalaun and Hamirpur. Growth in area, production and yield was estimated using data for 1980-2015 through compound annual growth rate and the highest growth was observed during 1980-1990 period. Modern cost concepts were used to assess the profitability of pulse cultivation and results revealed that the cost of cultivation per hectare was significantly higher in pigeon pea in comparison to gram, pea and lentil crops. The marketing charges paid by the village trader, wholesaler and retailer ranged between INR 20 to INR 40 per quintal for different crops. It was also observed that the quantum of marketable surplus and its percentage share to total production in pigeon pea, gram and lentil increased with the increase in size of land holding. The pulse production in the region faced with constraints related to production, processing and marketing. Hence, technologies and infrastructure need to be embraced through suitable policies to favour farmers, so as to maintain balance and keep the interest of both producers and the consumers.

It is known that inability of the farmers to exploit the available production technologies results in lower efficiencies of production. So, the measurement of technical efficiency in agricultural crops in developing countries like India gained renewed attention since the late 1980s from an increasing number of researchers. Accordingly, the present study has employed Data Envelopment Analysis (DEA) and Malmquist Total Factor Productivity Index to ascertain the Technical Efficiency of rice productivity (2021-2022) and its changes over the study period (2019-2020 to 2021- 2022) respectively in Telangana, India. This study was based on secondary data pertaining to rice productivity (output variable), fertilizer doses (NPK), seed rate, water applied and organic manure (input variables). The findings of Data Envelopment Analysis revealed that the overall mean technical efficiency score across all the Decision-Making Units was 0.860 ranged between 0.592 to 1.000. So, the Decision-Making Units, on an average, could reduce their input usage by 14 per cent and still could produce the same level of rice output. Further, fertilizers (60.54 kg/ha); seed (5.63 kg/ha); water (234.48 mm) and organic manure (3.76 t/ha) use can be reduced without affecting the current level of rice productivity. Malmquist Total Factor Productivity indices (2019-2020 to 2021-2022) revealed that the mean scores of technical efficiency change, pure technical efficiency change and scale efficiency change are more than one (1.153, 1.042 and 1.009 respectively), unlike technological change (0.983). All the Decision-Making Units showed impressive progress with reference to technical efficiency change (1.112) and it is the sole contributor for Total Factor Productivity change in rice cultivation. The DEA results suggest that farmers should be informed about the use of inputs as per the scientific recommendations to boost the technical efficiency of rice productivity in Telangana. It also calls for policy initiatives for distribution of quality inputs to the farmers to boost technical efficiency in rice production.

Power tiller-driven plow tillage and crop residue exclusionary Traditional Agriculture practices are expensive, labor demanding, soil damaging, and eco-unfriendly. Over the last several years, pursuits of crop production through sustaining the productive capacity of soils, and environmental quality, have raised concern to adopt Conservation Agriculture worldwide. Single tillage combined with herbicides and crop residue retention principles of Conservation Agriculture are being developed. Between 2016–2017 and 2017–2018, a two-year on-farm experiment was done in Bangladesh. We practiced two crop establishment methods; Traditional Agriculture: Plow tillage followed by three manual weeding without residue preservation of previous crop and Conservation Agriculture: Pre-plant herbicide + single tillage + pre-emergence herbicide + post-emergence herbicide; under rice–wheat and rice–wheat–mungbean systems. Data reveal that the Conservation Agriculture was more cost-effective crop establishment technique than Traditional Agriculture in rice, wheat, and mungbean by increasing the ratio of benefit to costs by 24.3%, 35.7% and 48.8%, respectively, with a savings in tillage operations (66.3%, 58.1%, and 57.6%, respectively), weeding expenditures (59.2%, 24.5%, and 42.2%, respectively), and manpower requirements (25.1%, 27.2%, and 31.3%, respectively). This has resulted in an increase of 32% productivity of rice–wheat–mungbean systems with the yield advantage of 16%, 31% and 37% in rice, wheat and mungbean, respectively. When mungbean was added, the rice–wheat system’s productivity rose by 43%. The rice–wheat–mungbean system under Traditional Agriculture had the highest land utilization efficiency (99.45%), followed by Conservation Agriculture (92.05%), which expanded the scope to include additional crops into rice–wheat–mungbean system. Moreover, the Conservation Agriculture had a 59.7% greater production efficiency than Traditional Agriculture, where the rice–wheat–mungbean system having the highest production efficiency (53.00 kg–1 ha–1 day–1), followed by the rice–wheat system (45.57 kg–1 ha–1 day–1).

Farmland productivity is low in the semi-arid regions (NR IV and V) of Zimbabwe due to desertification and land degradation. Nevertheless, demand for food is increasing geometrically hence the need to increase output per unit area. Agroforestry (AF) which is an ecologically based and dynamic system that integrates multi-purpose trees on farms can increase productivity and offer resilience to climate change vagaries. However, the role of AF in Zimbabwean smallholder farming systems is still not well investigated. Therefore, this review explores the role of agroforestry on agricultural productivity in the semi-arid regions of Zimbabwe. The aim was to enhance sustainable food security among the rural poor through sustainable agriculture. Incorporating multi-purpose trees on agricultural lands can significantly restore soil productivity and offer soil resilience to erosion by water and wind. If well implemented, the AF can be a viable option in mitigating the impacts of drought on agriculture in these drier and marginalized areas.

The 1991 Indian reforms aimed at economic liberalization, as a part of its economic structural adjustment, and transformed the nation’s economy into a more global market-based and service-oriented system, which revolutionized its agricultural trade facet. The new regime paved the way for the self-reliant Indian agriculture to expand its roots into the spheres of global competitiveness and export orientation. India enjoys competitive advantage in the international market and considering the growth in India’s exports of major agricultural commodities. This study employed Constant Market Share model to analyze the export performance of its various facets such as diversification, instability, elasticity, competitiveness, etc. The findings revealed that India’s growth performance of major agricultural commodities’ exports both in terms of quantity and value was found satisfactory (except wheat and cashew nuts, shelled (quantity)) during 1991-2020. During the recent past decade, i.e., 2011-2020, World Demand Effect (WDE) is the main sources of India’s agricultural export performance (due to general rise/fall in world demand given a constant market share of the India, unlike Market Distribution Effect (MDE), Commodity Composition Effect (CCE) and the Residual Competitiveness Effect (RCE) due to high inconsistency arising out of changes in external environment). Both MDE and RCE with respect to commodity-wise exports and CCE and RCE with respect to country-wise exports are found negative for majority of commodities and countries (markets) respectively. Consistently negative CCE for exports of agricultural products, total and across major export destinations were found more disheartening and this should deserve special attention. So, it is imperative to boost the export competitiveness of agricultural commodities from India and the future prospects of exports depend on how much the latest surge in COVID-19 infections in India affects its agricultural production and global demand conditions.

Kumar","doi":"10.36956/rwae.v3i2.514","DOIUrl":"https://doi.org/10.36956/rwae.v3i2.514","url":null,"abstract":"The 1991 Indian reforms aimed at economic liberalization, as a part of its economic structural adjustment, and transformed the nation’s economy into a more global market-based and service-oriented system, which revolutionized its agricultural trade facet. The new regime paved the way for the self-reliant Indian agriculture to expand its roots into the spheres of global competitiveness and export orientation. India enjoys competitive advantage in the international market and considering the growth in India’s exports of major agricultural commodities. This study employed Constant Market Share model to analyze the export performance of its various facets such as diversification, instability, elasticity, competitiveness, etc. The findings revealed that India’s growth performance of major agricultural commodities’ exports both in terms of quantity and value was found satisfactory (except wheat and cashew nuts, shelled (quantity)) during 1991-2020. During the recent past decade, i.e., 2011-2020, World Demand Effect (WDE) is the main sources of India’s agricultural export performance (due to general rise/fall in world demand given a constant market share of the India, unlike Market Distribution Effect (MDE), Commodity Composition Effect (CCE) and the Residual Competitiveness Effect (RCE) due to high inconsistency arising out of changes in external environment). Both MDE and RCE with respect to commodity-wise exports and CCE and RCE with respect to country-wise exports are found negative for majority of commodities and countries (markets) respectively. Consistently negative CCE for exports of agricultural products, total and across major export destinations were found more disheartening and this should deserve special attention. So, it is imperative to boost the export competitiveness of agricultural commodities from India and the future prospects of exports depend on how much the latest surge in COVID-19 infections in India affects its agricultural production and global demand conditions.","PeriodicalId":222396,"journal":{"name":"Research on World Agricultural Economy","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134163486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Agricultural researchers in developing countries were not able to give much attention on the adoption studies of agricultural technologies until the period of Green Revolution. These technologies are disseminated in rural farming community by agricultural extension professionals to boost farm efficiencies and productivity. This paper presents the systematic review of methods employed by previous researchers in studying agricultural technology adoption with special reference to rice. The review focuses on the study of rice technologies adoption in the Philippines and other related studies conducted by a Filipino author in other countries in the Asian Region. From 391 adoption studies identified, 22 papers were selected and included in the review. These papers were retrieved from Scopus database. This review revealed that papers focused on studying the adoption of rice cultivation practices employed quantitative techniques. Institutional factors were found to critically influence the decision-making of the farmers to adopt production technologies.
