Floristic diversity is characteristic for stubble-field plant communities. Those communities consist of both the species remaining after harvesting of grain and of the species developing in rootplant communities. The first part of this paper describes the plant communities of poor sites in the investigated region. It is based on 90 phytosociological records taken in August and September of 1972-1975 and on soil investigations. The <i>Panico-Setarion</i> alliance was made up of: 1) the <i>Digitarietum ischaemi</i> association, 2) the <i>Setaria glauca</i> community and 3) the <i>Ecbinochloo-Setarietum</i> association, the <i>Setaria glauca</i> community was divided into smaller phytosociological units.

Part I deals with the <i>Panico-Setarion</i> stubble plant communities. Part II describes the <i>Eu-Polygono-Chenopodion</i> plant communities. Part II is based on 89 photosociological records. The <i>Eu-Polygono-Chenopodion</i> plant communities develope on soil rich in nutrients (brown soil developed from silts loess and clay; alluvial soils developed from silts and loams; chernozem and black soils), belongs to wheat complexes. Two plant communities are distinguished: 1) <i>Oxalis stricta-Euphorbia esula</i> community; 2) <i>Veronica persica</i> community divided into four variants. The floristic diversity of these plant communities reflects the ecological conditions of the examined region.

In the Part I and II the stubble-field plant communities of lowlands agricultural utility complexes in South-Eastern Poland were introduced. The Part III contains a description of such communities occurring in mountain complexes. In the years 1972-1975, since August till September, 95 phytosociological records were taken on the area elevated from 300 to 650 m over the sea level, embracing the Carpathian Foreland and the Low Carpathian region. The research was conducted upon the typical, acid and leached brown soils, as well as on clay, dusty clay and silt alluvial soils belonging to three mountain complexes: wheat, cereal and oat-potatoes. The following communities were specified: I. <i>Setaria glauca</i> community, divided into two variants: 1) typical; 2) with <i>Aphanes arvensis</i>; II. <i>Veronica persica</i> community, divided into four variants: 1) with <i>Aphanes arvensis</i>, 2) typical, 3) with <i>Geranium dissectum</i>, 4) with <i>Aethusa cynapium</i>. The variant with <i>Geranium dissectum</i>, belonging to the community with <i>Veronica persica</i>, was considered as having the most mountain character.

The characteristics of communities found in unploughed stubble fields of the Mazowiecki Landscape Park and its agricultural buffer zone are presented in the paper. The association <i>Echinochloo-Setarietum</i> divided into a typical variant, the variant with <i>Galinsoga parviflora</i>, and the variant with <i>Bidens tripartite</i>, was the most frequently noted and floristically differentiated association. Patches of <i>Digitarietum ischaemi</i> were also frequently observed in stubble fields on the poorest habitats. Rarely, on fertile soils, small patches of floristically rich communities with <i>Veronica agrestis</i> were recorded. Periodically, excessively wet habitats were seldom occupied by the speciesrichest phytocoenoses of <i>Centunculo-Anthoceretum punctati</i>. Single patches of the community with <i>Setaria pumila</i>, the form with <i>Aphanes arvensis</i>, were observed only in the south-eastern part of the Park.

Setaria Glauca

Floristic diversity is a specific characteristic of stubble-fields plant communities. They contain both the species which remained after harvesting cereal communities and the species developing root-plant communities. This diversity is favoured by the ecological conditions of stubble-fields (warmth, light, frequent rainfall but first of all lack of competition on the part of cultivated plants). The first part of the paper describes the plant communities of poor sites in the investigated region. It is based on 133 phytosociological records taken in August and September in 1975-1980 and on soil investigations. Three types of communities have been distingushed belonging to the <i>Panico-Setarion</i> association. They are: (1) <i>Digitarietum ischaemi</i> association, (2) <i>Setaria glauca-Scleranthus annuus</i> community and (3) <i>Echinochloo-setarietum</i> association. They all can be divided into smaller phytosociological units.

In this of the presented paper results of the studies conducted in preceding four parts (I-IV) were synthetically assumed. On that background a comparative characteristics of specified stuble-field plant communities was conducted. It contains the most important features of communities and seats, in which they appear. In climatically, geomorphologically, hydrologically and with respect to soils differentiated conditions of South-East Poland, especially in former Rzeszów region, there were described stubble-field plant communities occurring as well on lowland, as on highland agricultural utility complexes. There were analysed 359 phytosociological records, in which 232 ones came from lowland, while 127 from highland complexes. The specified communities were included to two orders: <i>Secali-Violetalia arvensis</i> (suborder <i>Polygono-Chenopodienalia</i> : alliances <i>Eu-Polygono-Chenopodion</i> and <i>Panico-Setarion</i>) and <i>Cyperetalia fusci</i> (alliance <i>Nanocyperion flavescentis</i>). On the lowland agricultural utility complexes specified were seven types of communities: 3 belonged to <i>Panico-Setarion</i> alliance (association <i>Digitarietum ischaemi</i>; community with <i>Setaria glauca</i> and association <i>Echinochloo-Setarietum</i>), 2 to <i>Eu-Polygono-Chenopodion</i> alliance (the community with <i>Euphorbia esula</i> and <i>Oxalis stricta</i> as well the community with <i>Veronica persica</i>), while 2 associations from the <i>Nanocyperion flavescentis</i> (<i>Hyperico-Spergularietum</i> and <i>Centunculo-Anthocerotetum</i>) alliance. On the other hand, on the highland complexes of South-East Poland only 3 communities were found: 1) with <i>Setaria glauca</i> included to <i>Panico-Setarion</i> alliance, 2) with <i>Veronica persica</i> from <i>Eu-Polygono-Chenopodion</i> alliance and 3) <i>Centunculo-Anthocerotetum</i> association from <i>Nanocyperion flavescentis</i> alliance. The specified floral types, as well as lower units (variants and sub variants), reflected the mechanical structure, hydrological conditions and pH soils in their seats, what confrumed a great differentiation of soil conditions on the tested area.

This part of a series of paper presents a comparative characterization of selected stubble-field plant communities described in parts I-III. It encompasses the most important characteristic of the communities as well as the habitas in which they occur. In the differentiated climatically, geomorphologically, hydrologically and, most of all, in respect to soil type conditions of mideastern Poland, more precisely in the old limits of the Lublin voivodship, 6 types of stubble-field plant communities have been described and further classified into subunits; all of which have been isolated on the basis of the floristic composition of 330 analysed phytosociologocal records. The selected stubble-field plant communities were assigned to the suborder <i>Polygono-Chenopodietalia</i>. Among them, 3 plant associations known from root crop fields were identified: 2 belonging to the alliance <i>Panico-Setarion</i> (<i>Digitarietum ischaemi</i> and <i>Echinochloo-Setarietum</i>) and 1 belonging to <i>Eu-Polygono-Chenopodion</i> (<i>Oxalido-Chenopodietum polyspermi</i>). On most of the grain stubble-field of the Lublin region (almost 77% of the records) communities were found which could be assigned only to the alliances: community <i>Setaria glauca-Scleranthus annuus</i> to <i>Panico-Setarion</i>, community <i>Veronica persica-Sonchus asper</i> to </i>Eu-Polygono-Chenopodion</i> and community <i>Rorippa sylvestris-Oxalis stricta</i> which is an intermediate from between these alliances. The floristic types identified here, as well as their lower rancs (subassocietions variants, subvariants) were a reflection of the mechanical composition, nutritional, hydrological and pH conditions of the soils in their habitas and confirmed the high differentiation of soil conditions over the studied area.

In the years 1972-1975, between August and September, on lowlands and on the area elevated to 500 m over the sea level, 85 phytosociological records were taken. On the wet stubble-field of the tested area two associations of tiny plants, belonging to the alliance <i>Nanocyperion flavescentis</i>, were specified. They were the following: I. <i>Hyperico-Spergularietum rubrae</i> and II. <i>Centunculo-Anthocerotetum</i>. I. The <i>Hyperico-Spergularietum</i> community occurred only on lowlands, on the sand and silt soils belonging to rye complexes. It was divided into two variants: with <i>Illecebrum verticillatum</i> and the typical one. II. The <i>Centunculo-Anthocerotettum</i> was met as well on lowlands, as on highland agricultural utility compelxes. The highland form of the community, differentiated into two variants: with <i>Hypericum humifusum</i> and the typical one, occurred in the mountain wheatland complex, on brown silt soils. The lowland form of the community in a typical variant was found on different soils and complexes (1, 2, 4, 5, 8).
