The Joint Vertisol Project which, by its nature and intention has dealt with natural resource research and development, has inherently addressed the complexity of factors and interactions among them. This has led to the two dimension strategy of choice or prioritisation: 1) issues related to rese...

New semiDwarf wheat (Triticum aestivum L.) cultivars and new land management practices for Vertisols are being introduced in Ethiopia. Our objectives were to (i) determine the variation of N and P contents and concentration in the grain and whether these are related to grain yield, (ii) test cult...
