Ano: 2008 URL: http://purl.umn.edu/118411 A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia 31 Makombe, Godswill; Namara, Regassa E.; Hagos, Fitsum; Awulachew, Seleshi Bekele; Ayana, Mekonnen; Bossio, Deborah A.. Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

Ano: 2011 URL: http://purl.umn.edu/118298 Accounting of agricultural and nonagricultural impacts of irrigation and drainage Systems: A report of research in Taiwan and Sri Lanka in 2003 31 This paper is a collaborative research between the International Water Management Institute (IWMI) and the Agricultural Engineering Research Centre of Taiwan. This study contributes to IWMI’s program on the Comprehensive Assessment of Water Management in Agriculture. The research in 2003 consists of two components. First, research in Taiwan continues on estimating the positive and negative externalities of paddy-rice production. Second, research is being conducted in Sri Lanka to assess more broadly the impact of water resource development. In addition, two extensive literature reviews have been completed Tipo: Working or Discussion Paper Palavras-chave: Irrigation programs; Drainage; Rice; Crop production; Case studies; Consumer/Household Economics; Crop Production/Industries; Farm Management; Research and Development/Tech Change/Emerging Technologies. Ano: 2004 URL: http://purl.umn.edu/92407 ALLELOPATHIC EFFECTS OF ROSE WOOD, GUAVA, EUCALYPTUS, SACRED FIG AND JAMAN LEAF LITTER ON GROWTH AND YIELD OF WHEAT ( Triticum aestivum L.) IN A WHEAT-BASED AGROFORESTRY SYSTEM 87 IQBAL,J.; RAUF,H.A.; SHAH,A.N.; SHAHZAD,B.; Bukhari,M.A. ABSTRACT Selection of tree species under agroforestry systems is crucial to sustain the productivity of a crop. In present study, allelopathic effects of the leaf litters of 5 trees named Rose wood (Dalbergia sissoo), Guava (Pisidium guajava), Eucalyptus (Eucalyptus camaldulensis), Sacred fig (Ficus religiosa) and Jaman (Syzygium cumini) species on wheat growth and yield was examined. Leaf litter of each tress species was mixed in soil with two doses @ 100 and 200 g of leaves of each species per pot. Higher shoot length, shoot dry weight, number of spikelets per spike and biological yield were recorded in 200 g sun dried Jaman (Syzygium cumini) leaves. Total number of tillers per plant and number of ears per plant were higher under the application of...

Sustainable development and environmental consciousness is getting more important. It is a requirement of human activity – i.e. agriculture – to use less artificial chemicals, to decrease environmental burden and to ensure the adequate food supply, by fitting the basic economic criteria. Those farming alternatives are shown in the paper that are based on different chemical use in plant production. It is investigated how the profitability will change when we make changes in former farming activity, and what should be changed to reach income turning to organic faming or precision farming. In developing countries the main question is to produce the essential food demand, but it is necessary to examine the existence of fundamental important factors, the costs...

Ano: 2008 URL: http://purl.umn.edu/43321 Beneficial effects of bio-controlling agent Bacillus cereus IB311 on the agricultural crop production and its biomass optimization through response surface methodology 42 BANERJEE,GOUTAM; GORTHI,SRIKANTH; CHATTOPADHYAY,PRITAM. ABSTRACT Disease in agricultural field is a big problem that causes a massive loss in production. In this present investigation, we have reported a soil-borne bacterium Bacillus cereus IB311 which is antagonistic to plant pathogens (Pseudomonas syringae and Agrobacterium tumefaciens), and could make a substantial contribution to the prevention of plant diseases. To prove the practical application, the strain was directly applied in agricultural field. The results demonstrated that B. cereus IB311 has increased the production (20% and 26% in term of average pod number per plant, average seed number per pod, and seed yield per experimental plot) in ground nut (Arachis hypogaea var. Koushal, G201) and sesame (Sesamum indicum var. Kanak), respectively. To...

Ano: 2007 URL: http://purl.umn.edu/44517 Climate change impacts on crop risks and agricultural production in Finland 31 Lehtonen, Heikki; Kujala, Sanna. Climate Change is expected to improve crop production conditions significantly in northern Europe. In some studies a significant increase in agricultural production is expected in northern Europe while drought is becoming gradually more severe in Southern Europe and France due to climate change. Our analysis provides one of the first steps in evaluating the possible scale of changes in agricultural production and use of farm land in Finland, so far one of the least favoured agricultural areas in Europe. Drought in early summer and low temperature sum during growing period are currently the main growth limiting factors in Finland. Even though the early part of the growing period is likely to be dry also in the future, both mean and variance of crop yields...
