Abstract

Teff (Eragrostis tef (Zucc.) Trotter) is the oldest indigenous cultivated cereal crop in Ethiopia. It is known for its gluten-free nature. A field experiment was conducted to evaluate the effect of organic residue products on agronomic characteristics of teff. Treatments comprised factorial combination of five organic residues (compost (4.2 kg/plot), vermicompost (3.6 kg/plot), bioslurry-solid (3liter/plot)), bioslurry-liquid (1.5 liter/plot)), animal manure(12g/plot)), one mineral fertilizer NPSZnB (22 g/plot) and control, and two types of teff varieties (Negus and Felagot). The experiment was laid out in a factorial arranged randomized complete block design with three replications. The result demonstrated that organic residue products showed positive and highly significant differences on days to flowering, days to maturity, plant height, panicle length, lodging index, total biomass yield, and grain yield of teff as compared to the controlled treatment. However, the application of organic residue and mineral fertilization did not affect the lodging index and a number of off-types. Grain yield was maximized on both teff varieties grown with compost & vermicompost followed by NPSZnB, bioslurry solid, liquid, and animal manure. The lowest grain yield was obtained from the control treatments of the two teff varieties. However, there was no significant difference in yield with that of treatments fertilized with compost and vermicompost in both varieties. There was a significant interaction between organic residue and teff varieties for plant height, panicle length, total biomass, grain yield, and harvest index. Application of organic residue products significantly affects yield and yield components of teff than mineral and control treatments.
