Efficiency of modern agrotechnological methods of haricot (common bean) cultivation under irrigation in Astrakhan region

Purpose: to determine the most effective options for irrigation regimes, growth stimulation that meet requirements of resource-saving technology common beans cultivation under conditions Astrakhan region. Materials and methods. To study effect pre-sowing inoculation planting material (seeds) beans, as well a field experiment was set up. The object bean variety Rubin, admitted Nizhnevolzhsky Field studies observations were carried out according generally accepted statistical analysis obtained results B. A. Dospekhov method. Results. In course study, it found primary criteria in formation Rubin high yields are water regime, mineral nutrition biological potential leguminous plants. Pre-sowing with various biofertilizers had positive on yield studied crop and, accordingly, structure elements. This especially evident variants application Azotovit regimes 65-70-65 70-75-70 % minimum moisture capacity (MC). 4.2–5.4 t/ha, which differed significantly from control variant. Conclusions. Based should be noted maximum by number per plant (from 19.0 25.6 pcs.), seeds 45.2–63.0 pcs., also weight 1000 grains 352.0 364.0 g. increase relative without treatments +2.2 +3.1 depending regime crop. significant profit, level profitability, two MC when inoculating Azotovit.
