Abstract
This study analyzes the impact of beans produced under joint multiple agricultural technologies (Improved beans variety, soil carbon management, integrated pest control, and use of compost manure) on nutrition outcome of stunting, underweight, and wasting in Kenya, Uganda, and Tanzania. Adoption of technologies in East Africa has been in isolation only focusing on single technologies. However, farmers typically adopt joint multiple agricultural technologies as complements or substitutes thus technologies to be adopted dependent on early technology choices. The objective of the study was to analyze the impact of the nutrition outcome variables in terms of stunting, wasting, and underweight for the best joint multiple agricultural technology combinations as a set of explanatory variables (z). This study adopts the multinomial endogenous switching regression model to correct for the selection bias and endogeneity. Results indicate that joint multiple agricultural technologies had a significant impact on the overall nutrition outcome in East Africa households. It is concluded that households in East Africa rarely use a single agricultural technology but rather a combination of different joint technologies in order to improve their nutrition outcome. The findings recommend that households should adopt joint multiple agricultural technologies rather than focusing on single technologies.

Summary
Agricultural technologies have driven a revolution of global agricultural production since the mid of 1960s [32]. According to Foresight (2011), substantial gains in production were achieved in Germany through the greater use of improved crops, soil carbon management, integrated pest control, and compost manure among other technologies [22] This kind of technology model has not been fully applied in East Africa such as loss of biodiversity and soil fertility, stalinization, and water scarcity [2; 42]. Lukmanji et al, (2015) explain that nutrition outcome is the "terminal" variable that is directly influenced by anthropometric measures of underweight, stunting, and wasting [38] It is indirectly affected by multiple agricultural technologies crop improved varieties, crop management biotechnology, and soil fertility enhancement
