Farmer-friendly technologies toimprove chickpea production in theHigh Barind TractD. Harris, C. Johansen, and A.M. MusaResearch in the High Barind Tract (HBT) <strong>of</strong> Bangladesh to alleviate the effects<strong>of</strong> drought, pests, and micronutrient deficiencies on the production <strong>of</strong> chickpeais described. On-farm seed priming, whereby seeds are soaked in water for 8hours before being sown, was tested by farmers during four consecutive yearsfrom 1998-99 to 2001-02 and this increased grain yield consistently in all fouryears, with a mean increase <strong>of</strong> 37%. A lack <strong>of</strong> molybdenum (Mo) was shownto limit the nodulation, and hence the nitrogen nutrition and yield, <strong>of</strong> chickpea.Adding Mo and Rhizobium to soils increased nodulation and yield but was expensiveand somewhat impractical. Adding Mo and Rhizobium to seeds duringthe priming operation was shown to be a less costly and more viable alternativethat increased mean nodulation score in farmers’ trials by more than 70% andmean grain yield by 20%.The components <strong>of</strong> a simple integrated pest management package weretested, separately and together, in farmers’ fields. Bird perches, to facilitateaccess <strong>of</strong> insectivorous birds to the infested crop, reduced significantly theincidence <strong>of</strong> larvae <strong>of</strong> pod borer (Helicoverpa armigera) and the number <strong>of</strong>pods damaged by the pest. Use <strong>of</strong> Helicoverpa nuclear polyhedrosis virus wassimilarly effective, as was growing chickpea as an intercrop with linseed orbarley. However, reduced pest incidence was not consistently associated withincreased yield because <strong>of</strong> other constraints such as Botrytis gray mold andterminal drought. Nevertheless, the simple farmer-friendly interventions testedproved to be effective and would contribute to increasing the productivity andpr<strong>of</strong>itability <strong>of</strong> chickpea production in the HBT.Growing chickpea (Cicer arietinum L.) on residual soil moisture following the harvest<strong>of</strong> rainfed transplanted aman (T. aman) rice has become more popular recently withfarmers in the High Barind Tract (HBT) <strong>of</strong> Bangladesh (Islam et al 1994, Saha 2002,Socioconsult 2006). The market price <strong>of</strong> chickpea makes it an attractive crop to grow(Yusuf Ali et al 2007) but, although potential yield in the area is > 2 t ha –1 , actual yieldsare generally below 0.8 t ha –1 (Musa et al 2001). Major constraints to higher yields aredrought, particularly around the time <strong>of</strong> crop establishment when the surface layers <strong>of</strong>the soil dry out, but also at the end <strong>of</strong> the season if extended crop duration exhaustsFarmer-friendly technologies to improve chickpea production in the High Barind Tract 119
