Productivity of spring forage pea (Pisum sativum) in divergent agroecological conditions

INTRODUCTION Annual legumes are important, both in the terms of yield and quality as well as the protection of agroecological system: improvement of the soil physical, chemical and biological properties, fertilizer costs reduction, nutrient leaching prevention, moisture storage, erosion prevention, reduction of pesticide use and environmental protection; preservation of soil and water quality and thus human health. The most important annual forage legumes are forage pea (Pisum sativum L.) and common vetch (Vicia sativa L.), followed by broad bean (Vicia faba L.), hairy vetch (Vicia villosa Roth), Pannonian vetch (Vicia pannonica Crantz), ervil (Vicia ervilia (L.) Willd.) and grass pea (Lathyrus sativus L.), then narbon vetch (Vicia narbonensis L.), white lupine (Lupinus albus L.), blue lupine (Lupinus angus - tifolius L.) and cowpea (Vigna unguiculata (L.) Walp.), with high potential for intensive cultivation (Mihajlović et al., 2006b). The climate change impacts on agriculture are the result of a series of complex interactions with other environmental, social, economic and political factors and are mainly related to the biological effects on crop yields, as well as the resulting impacts on outcomes including prices, production, and consumption (Nelson et al., 2009). [...]the objective of this study was to determine the morphological diversity of pea genotypes, and to valorize the value of morphological characteristics and analyzes based on them, or to examine the productivity of facultative pea varieties. [...]despite these limitations morphological markers were and still are highly useful in the plant breeding. [...]resistance to lodging is a quantitative characteristic of pea, and it is related to the morphological characteristics such as root, stem hardness, height, leaf type, but as such it can be masked by an impact of the environment.
