Phenotypic variation of spike parameters in wheat grown on ameliorated soil

Abstract

Less productive agricultural soil, that is solonetz type, could be ameliorated in order to enhance usage value and broaden agricultural land. Grain weight per spike and spike weight of wheat grown on solonetz soil were examined in the article. Phenotypic variation of these traits as a response to environmental condition in six bread wheat varieties was followed through genotype by environment interaction in three vegetation periods. The results were compared on pure solonetz (control) and ameliorated solonetz (25 and 50t/ha phosphor-gypsum) to determine effect of amelioration on these two yield components.
