Integrated management of Aspergillus species and aflatoxin production in groundnut (Arachis hypogaea L.) through application of farm yard manure and seed treatments with fungicides and Trichoderma species

Groundnut (Arachis hypogaea L.) is an important cash crop in the lowland areas of Ethiopia. However, prevalence of Aspergillus invasions and subsequent aflatoxin contamination compromises the quality of groundnut kernels. This study was conducted to evaluate the effect of farm yard manure (FYM) and seed treatments against Aspergillus species pod colonization and aflatoxin accumulation under field conditions. The...

Physiological characterization of NADP-malic enzyme activity under 2,4-D toxicity in an aquatic fern, Azolla pinnata R.Br.

This work proposes NADP-ME activity as bio-indices for herbicidal sensitivity in Azolla pinnata R.Br. under 2,4-D toxicity. Azolla fronds were illuminated under saturated photosynthetic flux and bicarbonate induction. There was significant variation in the NADP-ME activity under light and dark conditions. This increased more when varying concentrations of 2,4-D were used for the up regulation of enzyme activity...

Effects of seedling age and rates of phosphorus fertilizer on growth and yield performance of onion (Allium cepa L.) under irrigation at Alage, Central Rift Valley of Ethiopia

Onion is an important cultivated crop as a condiment as well as a source of income for many farmers in Ethiopia. However, the productivity of the crop is much lower due to different problems. A field experiment was conducted to determine the effect of seedling age and phosphorus rate on growth and yield performance of onion at Alage, Central Rift Valley of Ethiopia, during 2016/2017 season. The treatments comprised...

Genotype and genotype by environment interaction and grain yield stability of medium maturity groups of soybean [Glycine max (L.) Merrill] varieties in Western Oromia, Ethiopia

The objectives of this study were to identify high yielding and stable medium maturity soybean varieties across environment and examine the influence of genotype × environment interaction (GEI) on grain yield of soybean varieties in western Oromia.  Seven early soybean varieties were evaluated at five locations (Bako, Gute, Billo, Chewaka and Uke) using randomized complete block design (RCBD) with three...
