To evaluate the effects of hydrogel polymer levels (0, 10, 20, 30 g m-2) and NO3:NH4 ratios (0: 100, 25: 75, 50: 50, 75: 25, and 100: 0) on dill seed yield and its essential oil constituents, an experiment was conducted in October 2012 in the experimental field of Islamic Azad University, Jiroft, Iran. Results showed that using 30 g m-2 hydrogel polymer with 75NO3-: 25 NH4+ ratio produced ...

: in order to study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of islamic azad university khorasgan (isfahan) branch located in khatunabad village (latitude 32o /40' n and longitude 51o /48' e). a split plot layout within randomized complete block design wit...

Interspecific and intraspecific hybrids show varying degrees of heterosis for yield and yield components. Yield-component traits have complex genetic relationships with each other. To determine the relationship of yield-component traits and fiber traits with seed cotton yield, six lines (Bt. CIM-599, CIM-573, MNH-786, CIM-554, BH-167, and GIZA-7) and three test lines (MNH-886, V4, and CIM-557) ...

in order to evaluate the utilization ability of drought resistance indices such as: yield index (yi), yield stability index (ysi), stress susceptibility index (ssi), tolerance (tol), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance index (sti) in sunflower hybrids, three separate experiments were conducted as randomized complete block design at the research field o...
