PRODUCTIVITY IN ENVIRONMENTAL STRESS SUMMARYThe frequency of extreme climatic events has increased due to global climate change. The objectives of this research were to investigate the influence of climatic conditions (precipitation and temperature) on productivity of red clover cultivars and populations with a different genetic background and to identify those with high forage yield potential in environmental stress. Twenty-three red clover cultivars and populations of different geographical origin were studied during two consecutive growing seasons (2012 -extremely dry weather conditions, 2013 -humid weather conditions) at the Agricultural Institute Osijek, Croatia. A field experiment was performed as a randomized block design with three replicates. Green mass and dry matter yield and plant height were measured in both growing seasons, whereas the seed yield was determined in the first year only. Results indicated the stability or adaptability of evaluated red clover cultivars and populations to a dry or humid weather production conditions. Croatian populations (CD-3, TP-2, TP-7) and cultivar Viva, Serbian cultivar K-17 and German cultivar Taifun exhibited the highest forage yield potential under both, dry and humid growing conditions and represent a valuable material to be used in red clover breeding programs dealing with tolerance to abiotic stress.

“…It is a short-term perennial legume that grows for about two to three years and is adapted to a wide range of climatic conditions, soil types, fertility levels, use patterns and management strategies. Red clover has a high yielding potential and cultivars grown in monoculture in humid climatic conditions can achieve in the second seasons over 80 t ha -1 of green mass yield and 15 t ha -1 of dry matter yield (Tucak et al, 2016). Red clover provides a high protein-rich feed for grazing livestock and during conservation is prone to the lower levels of protein degradation, compared to other legume feed sources (Phelan et al, 2015;Hart et al, 2016).…”

Characterization and interrelationships of soybean [Glycine max (L.) Merrill] yield components during dry and humid seasons

“…Unpredictable changes in weather conditions necessitate the need to conduct the research during two or more years to derive logical conclusion regarding genotype selection, especially when the experiments are conducted on the same geographical location (Ghodrati, 2013). The influence of climatic changes, particularly precipitation and temperature regimes have a direct and often negative influence on the quantity and quality of field crop yields (Kovačević et al, 2013;Tucak et al, 2016). The objectives of this research were to investigate yield components responsible for yield improvement and their relations during two seasons of opposite weather conditions, to determine the magnitude and the direction of the effect for each trait as well as their reaction to environmental stress.…”

Changes in yield and nutritive value of red clover (Trifolium pratense L.) and Festulolium (Festulolium braunii (K. Richt) A. Camus) under drought stress

“…It was also shown that the F. braunii hybrid grown in pure stand was the least sensitive to drought. According to Tucak et al (2016), high sensitivity of T. pratense grown in pure stand to drought, resulted in low yield of 23 cultivars and populations. Also Gaudin et al (2013) reported about the high sensibility of T. pratense in pure stand to drought.…”
