Potential use of rhizobium for vegetable crops growth promotion
The system of vegetable crops production required large amounts of mineral fertilizers. One of the possible alternatives to assure the economic and environmental sustainability of this production system would be the use of promoting growth plant rhizobacteria (PGPR). However, care is needed to select a microorganism to be used in crops that are usually consumed raw, so human health is not at risk. It was important to...

Effect of foliar application of iron on seasonal changes of some physical and chemical properties in berries of Halwani Lebanon grape cultivar (Vitis vinifera L.)
A field experiment was conducted in 2009 and 2010 growing seasons, to study the effect of foliar application of iron- chelated "Fe-EDTA" (0, 100 and 200 mg.l-1) on the seasonal dynamic of some physical and chemical properties of berries of Halwani Lebanon grape cultivar, grown on a calcareous soil in Mosul region, Iraq. The results revealed that the foliar application of 100 mgFe.l-1 caused a significant...

Seed germination of seeds preserved for about 20 years and that of seeds preserved for several years
From the herbage seeds, only alfalfa (Medicago sativa) showed about 3 - 5% germination ratio for 20 years old seeds. The results are consistent with that of Park and Kim (2009). No germination was observed from the other herbage species, but the decay of seeds were observed sometimes. However, the vegetable seeds preserved for several years showed high germination ratios. In conclusion, older seeds generally germinate a...

Malt Barley (Hordeum distichon L.) varieties performance evaluation in North Shewa, Ethiopia
Malt barley is the most important cereal crop grown in highland parts of Ethiopia. Even though Ethiopia has favorable environment and potential market opportunity, the share of malting barley production is quite low (about 15%) as compared to food barley. One reason for low production is the use of low yielding varieties. The present investigation was conducted in a randomized complete block design with three...

Calibration and validation of CERES-wheat in DSSAT model for yield simulation under future climate in Adet, North Western Ethiopia
Crop models are highly useful for simulating crop and soil processes in response to variations in climate and crop management. However, well estimated crop genetic coefficients are required. So the purpose of this study is to calibrate and evaluate the performance of CERES-wheat model and to simulate the climate change impacts on phonological stages and grain yield of bread wheat (Tay and Senkegna varieties) in the...
