use poor quality resources of water and soil for food production in developing countries must be considered. therefore, three experiments were conduct in complete randomize design with four replications, to study effects of gradually application of different salinity levels (0, 10, 20, 30, 40, 50 and 60 ds.m-1) at different growth stages (planting and early seedling) and gradually application s...

in order to study the effect of uniconazole and cycocle growth regulators on growth, yield and nutrients content of pearl millet in drought stress condition, a field experiment was conducted in 2007-2008 in agriculture research center of zabol university. the experiment was conducted in split plot base on randomized completely block design with tree replications. main plots were different level...

late-season drought is the major constraint reducing the productivity of chickpea. this experiment was carried out to study response of root and shoot characteristics in 12 chickpea genotypes to drought stress. two-drought stress levels (-3 and -6 bar) induced by peg 6000 and control in hydroponic condition at green house was performed. leaf relative water content (rwc), plant height, number of...

The critical nitrogen (N) dilution curve is a suitable analytical tool for in-season estimation of N status to implement precision N management. This study was undertaken for a comprehensive comparison of N dilution curves in Japonica and Indica rice to investigate, whether a single curve can be used for both rice ecotypes and to determine the most robust plant index for assessing N status in r...
