ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...

to assess the effects of different levels of nitrogen and phosphorous on yield and nutrient use efficiency of sugar beet (polygerm seed (cv. 7233)), this study was carried out in 1999-2001 in ardabil agricultural research station (alarough). the experiment contained two factors of: nitrogen in 4 levels (control, 100, 200 and 300 kg n/ha) and phosphorous in 3 levels (control, 100 and 200 kg p2o5...

degraded soils in northwest china are mostly nonproductive due to imbalanced nutrient and inadequate water supply. the effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha–1) combined with chemical fertilizers on soil water and water-use efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark loessial soil and over a per...

The Green revolution era has been the golden period for boosting food production specifically in South-Asia, but signs of fatigue late 1980s with a sharp decline factor productivity, stagnation crop yields dwindling and marginal farm incomes pose serious threat to security, agricultural sustainability, soil environmental health. In nutshell, growing concerns related health, productivity nutrien...

Abstract Introduction Nitrogen is a key nutrient for plants. Often less than 50% of the applied nitrogen fertilisers acquired by crops and can be easily lost into environment causing environmental pollution. Thus, to make agriculture more sustainable, it important investigate which factors determine use efficiency (NUE). We investigated whether NUE was higher in organically managed soils compar...
