The Development Economics Group at Wageningen University (WUR, the Netherlands), the International Maize and Wheat Improvement Centre (CIMMYT, Mexico) and the International Food Policy Research Institute (IFPRI, USA) are searching for
three PhD researchers
MAIZE and WHEAT CRP investigators from the global cross-CRP study on gender in agricultural innovation met at CIMMYT headquarters in El Batán, Mexico from 26 Feb to 1 March to take stock of progress so far and plan the next steps in the implementation of this unique research initiative.

Agricultural research is changing. In order to have a greater impact, research must be relevant to a greater variety of farmers in different contexts, while being both applicable and adaptable.
Ways must also be found to solve institutional constraints, which are very often beyond the researchers’ sphere of control. Policies can be changed to allow community seed production, better connections established between maize producers and traders, extension systems strengthened or willing agro-dealers found to commercialize new seeds.
M.L. Jat, senior cropping system agronomist in the Global Conservation Agriculture Program at CIMMYT, in collaboration with Hirak Banerjee, Rupak Goswami, Somsubhra Chakraborty, Sudarshan Duttac, Kaushik Majumdar, T. Satyanarayana and Shamie Zingore, recently published a study examining the socio-economic determinants of yield gap in maize. The study, “Understanding biophysical and socio-economic determinants of maize (Zea mays L.) yield variability in eastern India” was published in the NJAS -Wageningen Journal of Life Sciences and was made possible by a grant from the Maize CRP. The term “yield gap” refers to “the difference between actual yields and potential yield,” potential yield being “the maximum yield that can be achieved in a given agro-ecological zone.”
The purpose of the study was to investigate the key factors limiting maize productivity in the Malda and Bankura districts of the Indian state of West Bengal, in order to develop effective crop and nutrient management strategies to reduce the yield gap in the region.
The study compared the maize yield and socio-economic situation of farmers in the region and found that factors such as the caste or ethnic origin of farmers, availability of family labor, land ownership, use of legumes in cropping sequence, irrigation constraints, type of seed used, optimal plant population, labor and capital investment and use of organic manure had strong correlations to the maize yields farmers were able to achieve. The authors of the study hope that this information can facilitate the development and introduction of appropriate typology-specific crop management practices, in accordance with the needs of farmers and the socio-economic factors affecting their productivity, which could help to increase maize yields and reduce the yield gap for the region’s farmers.
