A two-year study (2007-2008) was carried out to explore the effect of split application of nitrogen fertilizer on yield, dry matter and harvest index of Marfona potato cultivar in Isfahan Agricultural Research Center, Iran. A randomized complete block design with a split plot arrangement with three replications was used. The main plots were three levels of nitrogen (100, 200 and 300 kg ha-1) an...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

to study drought resistance indices of eight potato cultivars and to determine the most tolerant variety, two experiments were conducted in the form of complete randomized block design with three replications (stress and non-stress conditions) in 2002. seven indices, ssi, tol, sti, msti, gmp, tol , and mp were used to determine tolerant varieties. it was found that mp, sti, gmp, and msti were a...

In order to evaluate the effect of salinity stress on growth, yield, and some physiological traits of forage sorghum cultivars, an experiment was conducted as split-plot based on a randomized complete block design with four replications at experimental farm of College of Agriculture, Shiraz University at 2014 growing season. Treatments were three levels of saline irrigation water (0.4 as contro...
