Response of green alga Ulothrix zonata to nitrogen and humic substances
Nitrogen and phosphorous are essential elements to aquatic biota. Different types of humic substances (HS), such as humic acid (HA) and fulvic acid (FA) have impact on the freshwater nutrients. The aim of the study was to examine how the presence of humic substances may affect nutrient availability to the growth of Ulothrix zonata (Weber and Mohr) Kutz.

Response of pearl millet (Pennistetum glaucum) cultivars to post-flowering drought stress
Two pearl millet (Pennisetum glaucum (L.) R. Br.) cultivars (Dadda and Shella) were evaluated at post-flowering stage for drought tolerance based on morpho-physiological criteria. The experiment was laid down in a randomized complete block design which comprised of a combination of two factors (cultivars and three water stress regimes; (well watered (36%), moderately stressed (21%) and severely stressed (9%)). Data...
