    Abstract: Onion is a popular vegetable crop, which has been produced for its daily uses and economic benefits. Downey mildew caused by the fungus Peronospora destructor is among the most important yield-reducing factor in onion production. The effect of three different levels of plant population and fungicide frequency with two different fungicides was studi... Show More

    Abstract: Potatoes are the world's fourth most important food crop, with climate, variety, seed quality, planting timing, nutrition, irrigation, pests, illnesses, and weeds all influencing its growth and productivity. Planting timing is critical for maximizing yields since it regulates temperature and light. Planting date effects on potato development and yi... Show More

    Abstract: The use of improper fertilizer type and amount, the cultivation of unimproved, low-yielding varieties and poor soil fertility are among the main obstacles limiting the productivity of maize in Ethiopia in general and in the study area in particular. A field trial was therefore initiated to identify economically justifiable amount of NPS fertilizer ... Show More

    Abstract: Maize is one of the most extensively grown crops in Ethiopia and the rest of the world. However, the maize production in Ethiopia is mainly threatened by the major foliar diseases like turcicum leaf blight (TLB), which cause up to 62.4% yield loss. To develop TLB-resistant maize varieties, it is important to look for resistant inbred lines. Therefo... Show More
