The three regional projects are led by the International Institute of Tropical Agriculture (in West Africa and East and Southern Africa) and the International Livestock Research Institute (in the Ethiopian Highlands). The International Food Policy Research Institute leads the program's monitoring, evaluation and impact assessment. Africa RISING appreciates support from the American people delivered through the USAID Feed the Future initiative. We also thank farmers and local partners at all sites for their contributions to the program and the CGIAR Trust Fund.

This study was, therefore, conducted in Lemu–Bilbilo district at 24 fields for two cropping seasons to provide farmers with P fertilizer recommendations based on soil fertility status and to enhance malting barley production. The experiment comprised six levels of P fertilizer (0, 10, 20, 30, 40, and 50 kg P ha−1) arranged in a randomized complete block design with three replications. The critical concentrations for soil P levels were found above 13 mg P kg−1 for Olsen and 16 mg P kg−1 for Bray II, and were sufficient for malting barley production on Nitisol of the study area and other similar agro-ecologies. The mean P-requirement factors were 5.80 and 6.10 mg P kg−1 for Olsen and Bray II, respectively. Results further revealed that P fertilization, at a rate of 30 kg ha−1, gave 10 and 73% mor...

As a result, some soils become non-responsive for Rhizobium inoculation besides P application. Based on the soil test result, the soil of experimental sites had low OM, N, P, S and Zn. Hence, an experiment was carried out on-farm, during 2016/17 growing season, at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield, nodulation, N and P uptake of chickpea. The experiment included twelve treatments developed via factorial combination of two level of inoculation (Rhizobium inoculated, un-inoculated), three level of S (0, 15, 30 kg Sulphur ha-1) and two levels of Zn (0, 1.5 kg Zinc ha-1). The treatment was laid out in randomized complete block design with three replications. Results showed that the highest mean nodule number (15.3) and nodule volume (1.3 ml plant-1) over locations were...

In the present study, Markov Chain probability model was performed to explain the long term frequency behavior of wet or dry weather spells during the main rainy season at Dhera, Central Rift Valley Region of Ethiopia. The study used 24 years (1984-2010) of rainfall data and weekly rainfall data was considered as standard to study the probabilities of occurrences of dry and wet weeks. Some reasonable and significant conclusions regarding specific time for land preparation, supplementary irrigation and soil conservation measures were obtained. The main rainy season starts on the 26 th week (25 th June -1 st July) and remains active upto the 40 th week (1 st -7 th October) this shows a total of 105 days of main rainy season that could occur. The coefficients of variation at the onset and withdrawal week are 69.4 and 99.2% respectively for the study site during the main rainy seas...

At the end of this chapter, learners will be able to: • Understand the potentials of cultivated forages towards the intensification of the mixed croplivestock system and climate change mitigations • Describe the essential features of selected forage crops and their utilization practices • Identify suitable forage growing niches for their effective integration in the smallholder system • Provide advice to livestock keepers and feed producers on the proper production and utilization of cultivated forages.
