MAIZE: a study on variety diffusion in Southern and Eastern Africa explains how, by , modern maize cultivars had come to be sown on million ha, or 40% of the total maize area ( million ha) in nine study countries (de Groote et al ). WHEAT: A global study on the impacts of international collaboration in wheat. Maize (Zea mays L.) is a wild grass also known as corn or Indian corn and belongs to the Poaceae (Gramineae) family. It was domesticated more than 7, years ago in Mexico and has spread rapidly throughout North and South America as a primary crop. In terms of production, maize ranks third after wheat and by: 9.

Zimbabwe is a suitable case study for the impact of the DT maize varieties because as in most SSA countries, in Zimbabwe, agriculture is the largest economic sector, contributing directly and indirectly to the livelihoods of more than 75% of the population (Kapuya et al., ).Cited by:
As a result of this program, Malawi for the first time in years exported over tons of maize and is food secure. To complement this, Jeff is championing the promotion of “green belts” or mega field demonstrations throughout Malawi for new maize varieties as a means of enhancing technology adoption amongst small-scale farmers. Finally, it is important to note that maize yields are also more variable than those of other crops (Martin et al. ; Poudel and Chen ), which has an impact on food security. This variability is due, among other factors, to the crop’s high water use, as well as management and genetic factors (Duvick, ).

Wheat yields for the dominant varieties will increase in Chitral district for all the climate change scenarios in which temperatures increase. The increase in yields in Chitral district is expected to be 14% and 23% respectively, for temperature increases of °C and °C (see S6 and S11 in Table 3).Cited by: The GPS is an extension of the binary PSM methods for the case of continuous treatment impact assessment (for details see Hirano and Imbens, ).
Unlike the ESR and PSM, the focus is on assessing the heterogeneity of treatment effects arising from different treatment levels, i.e., different intensities of adoption of improved wheat by: Assessing the Effectiveness of Maize and Wheat improvement Table FTE scientists by discipline working in maize improvement in the East and Southern Africa in The study goes beyond the usual binary variable treatment of adoption status of improved wheat varieties in impact assessment.
Accordingly, among the adopters, farmers who allocated less than 25%, %, % and % of their wheat area to improved wheat varieties obtained about, 1 and t ha-1 more than the non-adopter.
This study is part of a larger effort to explore the impact of agricultural research on poverty reduction.
It examines the diffusion and impact of hybrid maize in selected resettlement areas of rural Zimbabwe, paying particular attention to varieties.
Maize is the most important cereal crop in global cultivation, before wheat and rice, with an annual global production estimated at billion tons cultivated on million hectares .In Uganda, the annual production is estimated at million tons cultivated on one million hectares .Maize is a staple for many households, contributing about 11% of caloric intake of the Author: Isaac M.

From study area, three districts, namely, Chitral, D.I. Khan, and Peshawar, were selected through multistage sampling : Farhana Gul, Dawood Jan, Muhammad Ashfaq. The impact of the adoption of improved maize varieties on maize yields under the ESR framework is estimated in two stages: the first stage is concerned with the decision to adopt the improved maize varieties and is estimated by a probit model, and the second stage is concerned with the estimation of the relationship between the maize yields and Cited by: 3.
Yield reduction of 70 to 90% has also been reported under mild to severe water stress . Drought tolerant or resistant maize varieties developed from diverse sources of germplasm through wide testing may represent good sources of materials for on-farm trials [6,15].File Size: KB.
The study suggested that a delay in sowing of maize crop from June in the region after Wheat or Berseem harvesting has a significant decrease (p.
In western Himalaya, wheat is the principal crop (% of area) followed by rice (%) and maize (%). Valley bottoms and river basins with assured irrigation water are used for growing rice and wheat as summer and winter crops, respectively.
Maize is cultivated on upland slope terraces under rain-fed : N. Patel, A. Akarsh, A. Ponraj, Jyoti Singh. Olaf Erenstein is Director of the CIMMYT Socioeconomics Program. Since joining CIMMYT inhe has analyzed wheat and maize based innovations, systems and livelihoods in South Asia, and since drought tolerant maize and maize systems in Eastern and Southern Africa.
Prior to joining CIMMYT, he has worked in Pakistan, Mexico and West Africa. The greatest impact was achieved when farmers adopted CSD and improved maize varieties jointly rather than individually.
Our results are a validation of the need to strengthen smallholder diversification in the face of subsistence production and limited access to food : P. Marenya, M. Kassie, H.
Teklewold, O. Erenstein, M. Qaim, D. Rahut. The main objective of biofortifying wheat is to develop nutritionally enhanced wheat to increase people’s intake of iron and zinc. The International Center for Wheat and Maize (CIMMYT) is leading the HarvestPlus research effort in collaboration with national agricultural research and extension systems in South and West Asia, as well as with other advanced research institutes.

Introduction M aize (Zea mays L.) family (Poaceae) is the top yielding cereal crop in the world. Maize is the third most grown crop across the world, and the largest producer and exporter of maize is United States of America (USA) which contributes about % of the total production in the world (Global corn production, ).The USA has the highest maize yield (>.

This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, Kenya, Tanzania, and Uganda from The authors found that technology adoption is taking place across Eastern Africa but.

The International Maize and Wheat Improvement Center and the Globally, nearly half of the wheat varieties planted are CGIAR-related; in South, Central and West Asia and North Africa, that number rises to 70 to 80 percent of wheat varieties.
The authors would like to acknowledge the Standing Panel for Impact Assessment.The majority of variety trials presented in these books are sourced from the NVT program. NVTs provide independent information on varieties for growers. The aim of each NVT is to document a ranking of new and widely adopted varieties in terms of grain yield and to provide grain quality information relevant to delivery standards.In Central America, farmers have developed a ‘slash-and-mulch’ production system that preserves trees and shrubs, conserves soil and water, doubles yields of maize and beans, and even resists hurricanes.
