Influence of applied irrigation water on yield and yield components of peas (Pisum sativum L.)

Characteristics of contemporary farming are vast negative changes which consequently lead to uncontrolled natural resources exploitation. It is big demand regarding water usage on economic efficiency and efficacies way have tremendous relevance. This scientific work will show results based on three year of research (2010-2012) influence of irrigation norms on yield and yield components of green peas. Two-factorial split-plot method was performed on the soil type called Chernozem with slightly sightof clay and sandy traceon the location of trail fields of the extension farmer’s service Sombor. On the major examined plots were four versions in terms of irrigation (version without irrigation and versions with 10 mm, 20 mm, 30 mm water per irrigation portion) this research embraced four varieties of pea: Avola, Linkoln, Mastin and Polar. Average grain yield was 5.86 t/ha, however on the variants with irrigation succeeded grain yield was higher (17-37%) in comparison to non-irrigated variants. The highest grain yield has variety named Polar (6.61 t/ha). Average weight of 1000 grains for all examined varieties was 300.26 g, while number of grains per husk was 7.15. Exanimated plots with irrigation on have recorded highest average height of plants, they were longer and husk was wider, total weight of 1000 grains as well as number grains per husk in comparison to variant without irrigation. Through this research significant positive correlation between yield and plant hight (r=0.91**) has been succeeded, also correlation in number of grains per husk and husk width (r=0.85**), and husk length (r=0.59*). In addition, number of grains per husk was in significant positive correlation with plant height (r=0.58*), yield and number of grains per husk (r=0.51*), and plant height and husk width (r=0.51*). All final results from this research show that even with smallest portions of water for irrigation can come up to satisfy results of yield chosen varieties of green pea in way of normal usage of systems for irrigation and their rational explanation in practice in ours agro-ecological conditions.
