Over 2001-2003 there was researched an effect of various tillage methods on the reduction of weed infestation of a long-term fallow. The number of germinating weeds was analysed; the weeds had been obtained from a few-time-mixed soil samples collected from the top soil layers under the conditions of direct sowing, traditional ploughing, multistage ploughing and ploughing with a skim coulter. The results were compared with the abundance of weeds per 1 m2 under field conditions. The log-linear analysis showed a considerable effect of weather conditions (years) on the abundance of germinating weeds in 0-5, 5-10, 10-15, 15-20, 20-25 cm layers. Multistage ploughing and ploughing with a skim coulter significantly decreased the number of germinating weeds in the top soil layers, as compared with the traditional plough and direct sowing. After two years of varied tillage methods considerably lower weed abundance was recorded for all the tillage variants, as compared with the results.

Specimens of the genus Sorbaria cultivated in Polish dendrological collections have been examined. It appears that in Poland only 3 species are cultivated: S. sorbifolia, S. kirilowii and S. tomentosa. Some supposed hybrids of S. sorbifolia and S. kirilowii or S. tomentosa have been found in the Arboretum in Kórnik and Botanical Gardens in Poznań and Warsaw. A new, supplemented distribution map, a key to identification, and descriptions of the species occurring in Poland are given.

Hericium erinaceum (Bull.: Fr.) Pers. is an edible fungus of great significance in medicine. It is rarely found in Europe, in contrast, it is common in Japan and North America. Its fruitbodies have been well-known for hundreds of years in traditional Chinese medicine and cuisine. A cradle of H. erinaceum cultivation is Asia. In Eastern Europe is rare in natural habitats, but can be successfully cultivated. Both fruitbodies and mycelia are rich in active, health promoting substances. Tests of substances extracted from this mushroom carried out on animals and in vitro have given good results. They can be used in the treatment of cancer, hepatic disorders, Alzheimer’s and Parkinson’s diseases, wound healing. They improve cognitive abilities, support the nervous and immune systems. Promising results have been reported in clinical trials and case reports about the human treatment (e.g., recovery from schizophrenia, an improvement of the quality of sleep, alleviation of the menopause symptoms). The subject of this paper is to summarize information about the development of mycelium, the best conditions for cultivation of fruitbodies, bioactive substances and their use in medicine.

Light is an important factor deciding about yielding and morphological characters of Pleurotus carpophores. The objective of the research was to ascertain the impact of period and intensity of lighting on yielding and carpophore morphological features of four strains of oyster mushroom. The following strains were investigated: P. ostreatus: PX, K22 and P80 strains, P. pulmonarius: P20 strain. Fluorescent lamps with Day-Light were used to provide light in the cultivation room. The following lighting periods were used: 6, 10 and 14 hours/day and the applied lighting intensity included: 100, 300, 500 and 700 lx. Lighting exerted a significant impact on yielding. The highest carpophore crop was recorded when the applied lighting intensity was 500 and 700 lx for the period of 14 h/d. The highest mean mass of carpophores was recorded at 14-hour light exposure and 500 and 700 lx lighting intensity. Carpophore morphological features modified by the lighting period and its intensity included the cap diameter as well as the length and thickness of the stem.

The objective of the performed investigations was to compare mycelium growth of eighteen strains and two crossbred cultures of Lentinula edodes cultivated on agar media and on sawdust substrates from deciduous trees. On the basis of the performed experiments it is possible to conclude that the mycelium growth rate was a characteristic feature of the examined strains and crossbred cultures of L. edodes, although it depended on the type of the substrate on which it was growing.

Melons are highly demanding, thermophilous plants, which is why they are unpopular among fruit growers. Melon cultivation requires special treatment methods for the improvement of microclimatic conditions. Seven Polish melon cultivars are presently grown on the domestic market. They are well adapted to the local climate. The growth rate, vigor, fruit shape, fruit size, rind color and flesh thickness of those cultivars vary. The objective of this study was to determine the mineral content of edible parts of four field-grown melon cultivars in the Warmia region (NE Poland). This study discusses the mineral content of melon fruit subject to the investigated cultivar and cultivation method. In Poland, melon production is difficult and unreliable. The main problem is the selection of an appropriate cultivar and cultivation method. The analyzed material consisted of four Polish melon cultivars: Malaga F1, Melba, Oliwin, Seledyn F1, grown in a field experiment without protective cover, under polyethylene (PE) sheet cover, under non-woven polypropylene (PP) cover, with soil mulching, as well as with soil mulching under PE sheet cover or nonwoven PP cover. The highest concentrations of total N, K, Ca and Cu were determined in melon fruit of cv. Oliwin. Significant variations in total nitrogen and phosphorus levels in the edible parts of melon plants were noted subject to the applied cultivation method. Cucumis melo L. grown in the control treatment without protective cover was marked by significantly higher levels of total nitrogen and phosphorus in the fruit, compared with fruit grown with the use of other cultivation methods. The results of this study indicate that the fruit of melon plants cv. Seledyn grown in mulched soil under non-woven PP cover was characterized by the most favorable Ca:Mg and Ca:P ratios in comparison with fruit from the remaining treatments.

An investigation was done on the effect of different types of organic mulches that were applied in form of straw to the soil mulching process, on the weed infestation, number, and fresh mass of weeds in broccoli cv. Milady F1 (Brassica oleracea L. var. italica Plenck) and tomato cv. Polfast F1 (Lycopersicon esculentum Mill.) grown under polypropylene fibre as a covering, or grown without a covering. The different types of organic straw mulches were: rye (Secale cereale L.), corn (Zea mays L.), rape (Brassica napus L. subsp. napus), and buckwheat (Fagopyrum esculentum Moench.). All the organic mulches were applied at a dose of 10 t/ha. The effect of the mulches was compared to a control plot which had no mulch. The type of organic mulch applied to the soil mulching process influenced species composition, number, and fresh mass of weeds. This effect could be the result of the properties of the mulch (colour, structure, etc.) or the allelopathic effect on the germination and growth of individual weeds species. Irrespective of the investigated factors, 24 and 25 weeds species, respectively, were observed immediately after cover removal and before broccoli and tomato harvest. In the first date of estimation Chenopodium album L., Echinochloa crus-galli (L.) P. Beauv., Fallopia convolvulus (L.) Á. Löve, Stellaria media (L.) Vill., and Viola tricolor L. dominated, however, before the vegetables were harvested Ch. album, V. tricolor, Veronica arvensis L., and E. crus-galli dominated. An application of polypropylene fibre contributed to an increase in the number and fresh mass of weeds in both vegetables in the first date of estimation (after cover removal). During this period, vegetables cannot compete with weeds. It is important to note, though, that before the vegetables were harvested, a decrease was found in the number and fresh mass of weeds in the covered plots. The most efficient weed limiter, both after cover removal and also before the broccoli and tomatoes were harvested, was buckwheat and rye straw, respectively.

In the pot experiments conducted on the four mountain meadow soils with high reserves of soil potassium, a possible supply of this element for ryegrass supply was examined, when potassium was excluded or its dose was limited in the fertiliser. Differences in potassium removal with yield during exhaustive cultivation were difficult to justify using both static and dynamic indicators of plant supply with potassium. Thus, dynamics of potassium transformations in the soil corresponding to the uptake amount, was assessed through the speed with which reserve potassium was passing into the solution using oxalic acid, and by the share of potassium from unexchangeable forms in the removal of this element removal with ryegrass yield.

In the years 1992-94 studies were carried out on the occurrence of the broad bean weevil at the broad bean plantations and evaluation of the effect of insecticidal seed dressings upon this pest. The first beetles of the broad bean weevil begin their flight over the plantation before plant flowering (the 3rd decade of May, the 1st decade of June). A maximum of the laid out eggs was noted in the 2nd and 3rd decades of July. The best effects of the pest control were obtained by applying the insecticidal seed dressing Gaucho 350 FS-and by spraying plants at the pod setting phase with insecticide Karate 025 EC. The performed treatments reduced the seed damage of field bean by, on average, 16.6% and increased the yield by, on average, 0,62 t per ha.
