Evaluation of biocontrol agent and wheat straw mulch on yield and yield components of groundnut (Arachis hypogaea L.) genotypes in Central Tigray, Northern Ethiopia

Groundnut (Arachis hypogaea L.) is the 13 and 4th most important food and oil seed crops in the world. Groundnut is a source of vitamin E. However, due to low soil fertility, drought stress, fungal diseases and lack of appropriate management, production has been constrained qualitatively and quantitatively in the study area. Trichoderma harzianum and wheat straw mulch could increase the growth performance of groundnut...
