Intensification in plant growing is a direct reason for deteriorating soil properties, as well as conditions of plant growth and development. Aiming at improvement of soil fertility and structure, conservation tillage, limiting the processes of soil environment degradation, is introduced into garden crop production techniques. Field experiments were conducted in the years 2006–2008, on grey brown podzolic soil of impermanent structure. The experimental plant was scorzonera (Scorzonera hispanica L.) of ‘Duplex’ cultivar. Three intercrop plants were considered in the studies: common vetch (Vicia sativa L.), phacelia (Phacelia tanacetifolia B.) and oats (Avena sativa L.). There were also two ways of pre-sowing soil tillage: a) complex of pre-sowing practices, sowing of intercrop plant (2nd decade of August), pre-winter ploughing and putting green matter into soil, b) complex of pre-sowing practices, sowing of intercrop plant (2nd decade of August), spring ploughing and putting plant matter into soil, as well as two plant growing methods: on ridges and on flat soil. Significantly advantageous effects of spring putting intercrops into soil, growing of scorzonera on ridges and ploughing the soil with oats upon the total root yield were demonstrated. The examined experiment factors, however, did not significantly affect inulin, protein and dry matter contents in scorzonera roots. The most favorable tillage combination, as to inulin productivity was growing of scorzonera on ridges after spring ploughing oats with soil.

The method of tillage is one of the major factors determining the yield of root plants. Today we witness the degradation of soil on large cultivated lands. It is a result i.a. of more frequent tillage practices, and the omission of cover crops. The destruction of aggregate structures of the soil and the lowering of its organic matter content cause that conditions for growth and yields of the main crops are becoming worse. Field experiments were conducted in the years 2006–2008 on grey-brown podzolic soil with impermanent structure. The test plant was the rooted chicory (Cichorium intybus var. sativum Bisch.) of the ‘Polanowicka’ cultivar. This species has an important economical meaning, providing precious raw materials for inulin production. The experiments included: two kinds of presowing tillage: a) a complex of pre-sowing tillage and sowing of cover crops (2nd decade of August) and pre-winter ploughing and mixing the green mass with soil, b) a complex of pre-sowing tillage and sowing of cover crops (2nd decade of August), leave them in the field during the winter and ploughing the plant mass in spring; two types of plant growing: in ridges or in flat soil; three cover crops: common vetch, tansy phacelia and oats. Beneficial influence of mulching the soil with tansy phacelia on the total chicory root yield, compared with unmulched plots was observed. The highest content of inulin was found in chicory roots collected from plots mulched with common vetch. It was significantly higher than its content in roots coming from the plots mulched with oats. When the productivity of inulin per unit of area is taken into account, the most beneficial tillage combination was the tillage of chicory in ridges, after spring ploughing, mixing the mulch of common vetch with the soil. Both the cultivation of the plant in ridges and ploughed vetch affected the yield significantly. The factors of the experiment had no significant influence on the content of dry matter and protein in the roots of chicory.

The field experiment was carried out in 2006–2008 on lessive soil developed from medium dusty loams. Salsify (Tragopogon porrifolius L.) of ‘Mamut’ cv. was the experimental species. The experimental design included three intercrop plants: common vetch, lace phacelia, and oats; two soil tillage ways: a) set of pre-sowing tillage operations, sowing the intercrop plants (mid of August), pre-winter ploughing, mixing the green matter with soil, b) set of pre-sowing tillage operations, sowing the intercrop plants (mid of August), spring ploughing, mixing the plant matter with soil; as well as two plant cultivation manners: on ridges and on flat soil. It was found that spring ploughing made to mix the intercrop biomass with the soil as well as cultivation of plants on ridges significantly increased the total salsify root yields. Significantly positive influence of intercrop plants on salsify root yields, inulin content, inulin yield, and dry matter content was also recorded. Considering the roots yield and their nutritional value, plants cultivated on ridges after spring ploughing and mulching with lace phacelia appeared to be the most beneficial salsify cultivation combination.

The composition of microorganisms in the cultivation environment is extremely important since it affects the healthiness and hence the yielding of plants. The purpose of the present studies was to determine the effect of oats, common vetch and tansy phacelia as intercrop cover plants on the formation of microorganisms communities in the soil under the cultivation of root chicory and salsify. Before winter, cover plants formed an abundant green mass, which constituted the natural mulch on the surface of the land managed in two ways: 1) pre-winter ploughing, or 2) spring ploughing. The control was the conventional cultivation of these vegetables, i.e. without any cover plants. The microbiological analysis of the soil showed that regardless of the species of the studied vegetable, the total population of bacteria and the population of bacteria Bacillus spp. and Pseudomonas spp. were the highest when the soil was mulched with oats. A little fewer of those microorganisms occurred after using the mulch of common vetch or phacelia. On the other hand, the fewest bacteria were obtained as a result of the traditional cultivation of those vegetables. The total population of fungi in the soil mulched with oats was the lowest, whereas the most of fungi occurred in the control. The cultivation system, i.e. performing the spring or pre-winter ploughing, rather had no significant effect on the population of the studied microorganisms in the soil. Among the studied vegetables, the following were most frequently isolated: Alternaria alternata, Fusarium culmorum, Fusarium oxysporum, Pythium irregulare, Rhizoctonia solani, Sclerotinia sclerotiorum and Gliocladium spp., Penicillium spp. and Trichoderma spp. Laboratory tests showed that both the cultivation of root chicory and salsify which included cover crops promoted the development of antagonistic bacteria (Bacillus spp. and Pseudomonas spp.) and fungi (Gliocladium spp., Penicillium spp. and Trichoderma spp.) better than the traditional cultivation of those vegetables.

Salsify has a remarkable taste and nutritious values. It is a rich source of inulin – a glycoside which has a positive effect on human and animal organisms. The paper presents studies on the species composition of soil-borne fungi infecting the roots of Tragopogon porrifolius var. sativus cultivated with the use of oats, tansy phacelia and spring vetch as cover crops. In a field experiment the cover crops formed abundant green mass before winter and it constituted a natural mulch on the surface of the plough land. It was managed in two ways: 1) mixed with the soil as a result of spring ploughing, or 2) mixed with the soil as a result of pre-winter ploughing. The conventional cultivation of salsify, i.e. without cover crops, constituted the control. The studies established the number and health status of four-week-old salsify seedlings and roots with necrotic signs. A laboratory mycological analysis made it possible to determine the quantitative and qualitative composition of fungi infecting the underground parts of Tragopogon porrifolius var. sativus. The emergences and the proportion of infected salsify seedlings varied and depended on the species of the mulching plant. The smallest number of infected seedlings was obtained after the mulch with oats, slightly more after the application of spring vetch or tansy phacelia as cover crops, and the most in the control. Regardless of the species of the mulching plant, the following were frequently isolated from the diseased seedlings and roots of salsify: Alternaria alternata, Fusarium culmorum, Fusarium oxysporum, Penicillium spp., Rhizoctonia solani and Sclerotinia sclerotiorum. Rhizoctonia solani and Sclerotinia sclerotiorum proved to be the most harmful towards the roots of salsify. The system of cultivation, i.e. performing spring or pre-winter ploughing, had no significant effect on the total population of fungi.

The field experiment was carried out in 2006-2008 in the Felin Experimental Farm (University of Life Sciences in Lublin) on podzolic soil developed from dusty medium loam. Root chicory (Cichorium intybus L.) var. sativum (Bisch.) Janch. cv. Polanowicka was involved in the experiment. The experimental factors were 3 species of intercrop plants: common vetch (Vicia sativa), phacelia (Phacelia tanacetifolia), oat (Avena sativa) and 2 dates of ploughing-in: pre-winter and spring. In total, 26 taxons characteristic for vegetable plantations were identified in chicory weed infestation. Monocarpic species dominated, among which Senecio vulgaris, Chenopodium album, Lamium amplexicaule, Galinsoga ciliata, and Capsella bursa-pastoris were predominant. The date of ploughing-in did not significantly affect the status and size of weed infestation of chicory plots. Short-lived species occurred after pre-winter ploughing-in, while perennial – after spring ploughing-in. The application of intercrops significantly reduced chicory weed infestation as compared to the cultivation with no intercrop. The ploughing-in of Avena sativa biomass appeared to be the most efficient. The intercrop plants reduced the occurrence of Senecio vulgaris and Capsella bursa-pastoris which were the most numerous in the treatment without intercrops. Biomass of Vicia sativa favored the growth of Chenopodium album and Lamium amplexicaule. The secondary weed infestation did not depend on agrotechnical factors applied during the experiment.

The aim of the study was to determine the influence of cover crops biomass, mixed with the soil on different dates and with the use of different tools in field conditions. The cover crop biomass had a beneficial influence on the total porosity of the 0-20 cm layer of the soil after winter. The highest porosity was achievedwith cover crops of buckwheat, phacelia and mustard, the lowest with rye. During the vegetation period the highest porosity of soil was observed in the ridges. Among the remaining non-ploughing cultivations, pre-winter use of stubble cultivator proved to have a beneficial influence on the soil porosity, providing results comparable to those achieved in conventional tillage. The differential porosity of the soil was modified not only by the catch crops and the cultivation methods applied, but also by the sample collection dates, and it did change during the vegetation period. The highest content of macropores after winter was observed for the phacelia cover crop, and the lowest in the case of cultivation without any cover crops. Pre-winter tillage with the use of a stubble cultivator increased the amount of macropores in soil in spring, and caused the biggest participation of mesopores as compared with other non-ploughing cultivation treatments of the soil. The smallest amount of mesopores was found in the ridges.

The quantity of weeds depends on biotopic factors, on the supply of seeds in the soil and agrotechincal procedures, which stimulate or inhibit weed germination and development. Intercrop plants applied in contemporary systems, modifying the soil environment, also influence the weed infestation of crops. The aim of conducted studies was to determine the effect of intercrop plant application and kind of ploughing upon the state and degree of Spanish salsify weed infestation. In the field experiment with growing Spanish salsify (Scorzonera hispanica L.) the following intercrop plants were applied: common vetch (Vicia sativa L.), tansy phacelia (Phacelia tanacetifolia Benth.), oat (Avena sativa L.), as well as differentiated soil tillage: conventional plough cultivation with pre-winter mouldboard ploughing without intercrop; intercrop plant sowing plus deep pre-winter ploughing; intercrop plant sowing plus spring ploughing. In Spanish salsify weed infestation jointly 37 taxons of weeds were determined, among which the most numerously occurred: Chenopodium album L., Senecio vulgaris L., Capsella bursa-pastoris (L.) Med., Lamium amplexicaule L., Galinsoga ciliata (Raf.) S.F. Blake and Urtica urens L. The numerical force of primary and secondary Spanish salsify weed infestation after pre-winter and spring ploughing was similar. Intercrop plants significantly limited the primary and secondary weed infestation of this plant. The smallest quantities of weeds grew in objects where oat was the intercrop plant, and the largest – in cultivation without intercrops. Intercrop plants limited the occurrence of Senecio vulgaris and Capsella bursa-pastoris in primary weed infestation, and oats intercrop also limited the occurrence of Lamium amplexicaule and Senecio vulgaris in secondary weed infestation of Spanish salsify.
