The effects of Leucaena leucocephala and L. pallida prunings and cattle manure on maize nutrient uptake and yield were investigated in a hedgerow inter-cropping trial in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping) is an agroforestry system in which trees are grow...

Pot trials and laboratory phosphorus (P) sorption studies were conducted to evaluate the response of seven Ethiopian clover species (T. decorum, T. steudneri, T. quartinianum, T. rueppellianum, T. schimperi, T. tembense, and T. subterraneum) to applied P and further to determine the critical exte...

Eight chemical methods were employed for estimating the available P in 32 Ethiopian soils using Phasey bean (Macroptilium lathyroides c.Murray) as a test crop grown in small pots in a glasshouse and the soil test values then correlated with plant characteristics. Olsens' method gave the highest c...

Poor drainage of Vertisols and nitrogen (N) and phosphorus (P) deficiencies are some if the major constraints to food and feed production in the Ethiopian highlands. The effects of soil drainage and P supply on N fixation by annual trifolium species and their residual value to succeeding crops wa...

Balances between nutrients applied or mineralized and nutrients removed in maize grain and stover were calculated in a hedgerow intercropping experiment in which Leucaena leucocephala and L. pallida prunings and cattle manure were applied. Hedgerow intercropping (also called alley cropping) is an...
