Response to applied N was related to the soil total N content in Aludeka and Shinyalu, but not in Emuhaia, probably related to the high use of partially decomposed

First, the comparison of zai vs. flat planting, both unamended, resulted in a 3- to 4-fold (in one case, even 19- fold) increase in grain yield on-farm in both years, which points to the yield e
