As a unit of the environment, it has a profound influence on the health, efficiency, social behavior, satisfaction, productivity, and general wellbeing of the individual and the entire community. However, one of the critical challen...

By using the stochastic frontier methodology, this study investigates the technical efficiency and total factor productivity (TFP) growth in Indonesian provincial economies during the period from 1993 to 2000. In addition to the estimation of provincial technical efficiency, factors that contribute to technical inefficiency are also examined and the TFP growth is decomposed into technological p...

introduction: in this study, total factor productivity growth components in rough rice production are assisting by econometric approach and stochastic frontier function during 2005-2013 for several provinces (mazandaran province, guilan province, golestan province, fars province, khoozestan province). according to food and agriculture organization statics, iran is the 3rd importer and 20th expo...

in order to study of nitrogen absorb and use efficiency of wheat (triticum aestivum) and wild oat (avena fatua) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. the first factor was competition between wild oat (densitie...

soilless media have different physical properties. change in air space of mix substrate can cause change in fertigation management and plant growth and yield. physical properties (water holding capacity, effective air-filled pore space, effective pore space) of 50 mixed substrates were measured to evaluate the effect of air-filled pore space on growth of tomato transplant and it's water us...
