life cycle assessment (lca) had proven to be an appropriate assessment tool for analysis of agri-food products by identifying, quantifying and evaluating the resources consumed and emissions released into the environment. this study was performed for evaluation the environmental impacts of potato agroecosystems based on nitrogen levels by using lca methodology. tuber yield mean during 1999-2013...

a factorial experiment based on a randomized complete block design with three replications was carried out in order to study the effects of tuber size, nitrogen fertilizer and harvest date on yield and yield components of potato. this experiment was conducted in a grower’s farm in uraki village located in chabahar city, in 2011. in this experiment, the treatments were two levels of tuber size (...

In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...

The effects of three harvesting dates; 120 150 and 180 days after planting (DAP) and four potassium fertilizer levels; 0, 48, 72 and 96 Kg K2O fed -1 , on vegetative growth characteristics, tuber yield potential and quality of Jerusalem artichoke (cv. Balady) were studied. Two field experiments were conducted during the two successive summer seasons of 2001 and 2002 at the Experimental station ...

Greenhouse experiment was conducted for four months using Leucaena leucocephala and Pleurotus tuber-regium to determine their bioremediation potentials. Leucaena leucocephala, Pleurotus tuber-regium and Leucaena leucocephala combined with Pleurotus tuber-regium were tested for their ability to improve nutrient (N, P, K, total organic carbon) and reduce heavy metals (Zn, Ni, Pb, Cu) of soil poll...

in order to investigate the effects of nitrogen fertilizer on yield and yield component of potato, (solanum tuberosum l.) and researching for direct and indirect effects of some important agronomic traits, an experiment was conducted based on randomized complete blocks design with three replications at the agricultural research station, ferdowsi university of mashhad, iran, during 2008. chlorop...
