Environmental contamination, herbicide resistance development among weeds and health concerns due to over and misuse of synthetic herbicides has led the researchers to focus on alternative weed management strategies. Allelochemicals extracted from various plant species can act as natural weed inhibitors. In this study, allelopathic extracts from four plant species sorghum [Sorghum bicolor (L.) Moench], mulberry (Morus alba L.), barnyard grass [Echinochloa crusgalli (L.) Beauv.], winter cherry [Withania somnifera (L.)] were tested for their potential to inhibit the most problematic wheat (Triticum aestivum L.) weeds wild oat (Avena fatua L.) and canary grass (Phalaris minor Ritz.). Data regarding time to start germination, time to 50% germination, mean germination time, final germination percentage, germination energy, root and shoot length, number of roots, number of leaves, and seedling fresh and dry weight was recorded for both the weeds, which showed that mulberry was the most inhibitory plant species while sorghum showed least allelopathic suppression against wild oat. Mulberry extracts resulted in a complete inhibition of the wild oat germination. The allelopathic potential for different plants against wild oat was in the order: mulberry > winter cherry > barnyard grass > sorghum. Mulberry, barnyard grass and winter cherry extracts resulted in a complete inhibition of canary grass. Sorghum however exhibited least suppressive or in some cases stimulatory effects on canary grass. Plants revealing strong allelopathic potential can be utilized to derive natural herbicides for weed control.

The aim of the work was to evaluate the risk of cultivation of cucumber pickling cultivars in Poland caused by unfavourable thermal conditions of soil. To achieve the goal of the work used starting data collected from 28 experimental stations of the Research Centre for Cultivar Testing (COBORU) and 47 meteorological stations of the Institute of Meteorology and Water Management (IMGW) in 1966–2005 were used. Curvilinear regression analysis was used to determine the relation between the total and marketable yield of cucumber and soil temperature at the depth of 5 cm in the period of sowing-the end of harvesting. Potential, at least of 5%, reduction in the total yield of cucumber occurred when average soil temperature at the depth of 5 cm in the period from sowing to the end of harvesting amounted to ≤17.9°C and of the marketable yield ≤17.3°C. The highest reduction in yield, occurring in south-west and south-east part of Poland. The reduction was from 15 up to over 18% in the case of the total yield and from 12 up to 15% in the case of the marketable yield. On average, it occurred respectively every 1.5–2 years and 2.5–3 years. Taking into account the data from the whole country area in 1966–2005, a considerable increase appeored by 0.2°C/10 years in soil temperature in the period from sowing to the end of harvesting. The highest increase by 0.4°C/10 years was recorded in southern and central Poland and in the western part of the Masurian Lakeland where a risk of cucumber cultivation caused by too low soil temperature will probably in the incoming years undergo the quickest reduction.
