Field experiment was conducted for 2 seasons to study the influence of drip fertigation in combination with or without bio fertilizers on yield, plant uptake and soil fertility of Bt cotton. The treatments comprised of four levels of drip fertigation viz., 75, 100, 125 and 150 per cent of recommended dose of fertilizers (RDF, NPK) combined with and without bio fertilizers, drip irrigation w...

In order to investigate the effect of bio-fertilizers on the yield and yield components of flax lines, a study was conducted during 2010 growing season at the Agricultural Research Station of Saatlo in Urmia. A split plot design based on randomized complete blocks with four replications was performed in this study. Main factor (a) consisted of fertilizer application form (a1 = control without n...

The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV – 1 TeV which can be easily observed on future colliders and ...
