Working Paper 1993

Autor: Saka, A.R. Haque, I.

An alfalfa field experiment was conducted at the Debre Zeit Experiment station for a period of 2 years with the main objective of investigating the effects of cattle manure om dry matter yields, plant tissue nutrient concentration and plant nutrient uptake. Dry matter yields were significantly in...
