Farmer participatory variety selection in multi location on-farm sorghum variety testing

  1. Sorghum plays an important role in the diets and economies of the people of Nigeria. The average per capita annual sorghum consumption in major sorghum growing areas, is more than 75 kg/person and it contributes to more than 50% of the dietary micronutrient requirements, particularly in the northern state's smallholder farmers. However, since 2009, there has been a decline in its production in terms of area harvested and yields (FAOSTAT, 2012), attributable to the unavailability and dissemination of im- proved varieties and hybrids that are adapted to the Sudan and Sahel eco- logies with unpredictable and low rainfall pattern and Striga infestation. In line with the Nigerian Agricultural Transformation Agenda (ATA), aimed at strengthening the economy through sorghum commodity transformation, ICRISAT in collaboration with Institute for Agricultural Research Ahmadu Bello University (IAR/ABU), developed and evaluated sorghum varieties with farmer participatory evaluation across major sorghum growing eco- logies during 2015 rainy season. • baCkground To assess the newly developed sorghum varieties for their early maturity and high grain yield adapted to the dry savannah agro-ecology. • objeCtives Four sorghum varieties were evaluated at On-farm across 9 locations ( Bakori, Gambawa, Wajeri, Gumel, Ikara, Kofa, Ningi, Zango & Zaria) with 5 farmers at each location serving as replications, during 2015 cropping season to test the farmer preferred selection against local checks. On a plot size of 10x10m2 , hills were spaced at 30cm and the recommended fertilizer rates were applied at three and six weeks after planting. Participatory selection activities were carried out for each of the locations for farmers to rank their choice. Data from the on-farm trials from the individual locations for days to 50% flowering and grain yield were recorded and analyzed. • methodology • Community selection and field identification • Seed distribution and planting • Weeding and fertilizer application • Farmer participatory evaluation at grain physiological maturity. • aCtivities Result from farmers’ participatory rating across the various agro-ecologies rated 12KNICSV-188 and 12KNICSV-22 as their 1st and 2nd respectively in the Sudan and sahel zones. This is in consonance with the analyzed field data where the mean performances for yield and other agronomic characters from nine locations combined indicated that 12KNICSV-188 and 12KNICSV-22 were the earliest to attain days to 50% flowering in 67 and 68 days respectively. Average yield for the 9 locations combined showed that 12KNICSV-188 and 12KNICSV-22 had high grains yield of 2818kg/ha and 2356kg/ha respectively (Table 1) GGE Biplot analysis of On-station revealed that the clustering of Ikara and Birninkudu located Sudan Savannah, and that Sokoto and Zangon Daura located in the Sahel favors the performances of 12KNICSV- 188 and 12KNICSV-22 (Figure s1 & 2) being farmers' choice. • results and main aChievements • Current partnerships and future engagements for out sCaling Based on the mean performances, for early maturity and high grain yields in the Sudan and Sahel agro-ecologies coupled with farmers rating, 2 sorghum varieties; 12KNICSV-188 and 12KNICSV-22 were recommended for release to these agro-ecologies as climate smart varieties. • ConClusions Collaboration is active with Federal Ministry of Agriculture and Rural Development, National Research Institutes, NARIs, Agricultural Research Council of Nigeria, (ARCN), National Agricultural Seed Council (NASC) Universities, States Agricultural Development programs (ADPs) of Ministries of Agriculture and Rural Developments and relevant NGOs.
