The aim of the research was the estimation of growth and yield of 'Ligol'cv. apple trees depending on rootstock and polymeric sorbent called geo-composite SAP . The experiment was conducted in years 2006-2010 in Research Station be-longing to department of Horticulture at Wroclaw University of Environmental and Life Sciences. Two-year-old trees of ‘Ligol' cultivar were planted in the spring 2006 in 3, 5 x 1, 0 m spacing, on three rootstocks: M.9, P 60 and M26. The second factor of the experiment was application of geo-composite SAP in the form of agrożel placed inside geo-textile as strip with the width of 10 and length adjusted to a plot with trees The wet geo-composite, was put on the bottom of holes before the trees planting. The experiment was established according with randomized split-block me-thod, in three replication with tree trees on each plot. The trees were fruiting as early in the year of planting. Fruit yield was from particular tree determined by separate weighing. The weight of one fruit was estimated on the basis of the yield from one tree and number of picked up fruit. Tree vigour assessed taking into ac-count the increase in cross sectional area of the trunk, ...
The experiment carried out over 2010-2012 at the experimental field of Crimean Agrotechnological University in Simferopol, Ukraine (44°56'N, 34°06'E). It was investigated the effect of cultivation method (cultivation from seedlings and direct sowing to the ground) and the date of seeds sowing - direct to the ground (first 10-days of March, second 10-days of March, first 10-days of April) - for seedlings (second 10-days of February, first 10-days of March, second 10-days of March); distance between the plants in rows (20, 25 and 30 cm) on the morphological features and yield of leek ‘Sizokrył'. Leeks were grown in double rows spaced by 40 cm. Plants grown from seedlings were characterized by the better biometrics features than grown from seed sowing directly into the ground. Delaying the sowing date of seeds by 10 days at seedlings production (compared to control date i.e. first 10-days of March) influenced the most favourable on the biometrics features of the yield. In the leek cultivation from direct sowing to the ground the earliest date caused achieve the plants with the best parameters. Leeks cultivation in the distance of 25 cm in rows contributed to achieve plants with significantly the highest stalk diameter and the highest ...
The research was conducted in the years 2007 -2009. The trial was set up as split -plot with four replication. Experience related to the impact of mulching - the use black synthetic mulches (polyethylene film, polypropylene fabric and polypropylene nonwoven) on the yield and fruit biometric features and the content of selected nutrients in the cultivation of two cultivars peppers: 'Denis F1' and 'King Arthur F1'. Seedlings planted permanently in place in mid-June at a spacing of 50 to 50 cm. Harvesting were made gradually as of fruit ripening. Based on the of the obtained results it was found that the yield of peppers depended on the weather conditions and was variated in the years of experience. Higher yields fruits collected from the 'Denis F1' especially grown on leaf litter of black polyethylene film. The longest fruits were collected from plants mulched nonwoven polypropylene. Thicker pericarp had a variety of ‘King Arthur F1' mulching with polyethylene film. Mulching the soil favored the accumulation of L-ascorbic acid, total and reducing sugars in the fruits of peppers.The results showed that all types of mulches have contributed to a reduction in dry matter content in fruits compared to the control ...
The purpose of the study was the analysis of chosen vegetables on the basis of national production and one of the Groups Vegetables Producers and production trends in 2011-2014 as well. The data obtained were from the Central Statistical Office and directly from the company ‘Daukus'. In the period 2011-2013, taking into account the whole country the highest prices were recorded in 2013, which could have the effect of increasing crop acreage and yield in 2014. ‘Daukus' produced most product in 2014 and it had an impact on increasing the area and favorable conditions weather. Vegetable prices in 2014 significantly decreased by increasing the supply and political factors. In the production of vegetables in Poland is visible intensification, which means that there are fewer farms, but those that exist to increase the amount of vegetables produce. ...
