THE INFLUENCE OF THE WASTE WITH MOLYBDENUM AND POULTRY MANURE ON THE PHOTOSYNTETIC AND SYMBIOTIC SOYBEAN POTENTIAL DEVELOPMENT

Abstract

Photosynthetic apparatus establishment is one of characteristics that indicate growth conditions of plants. Development of soya bean leaf area depends on application of microelements with this pattern being pronounced in the course of two years of pot experiments. The amount of nodules on the soya bean roots during the phase of full seed ripening rose by 20% due to poultry manure addition and by 38% due to industrial waste containing molybdenum. It was found that the joint application of these fertilizers has favourable influence due to its interaction. When aggregating data of pot experiment to average during 2014-2015, similar patterns were established with respect to the microelements impact on the amount and mass of nodules on the soya bean roots. Supply of legumes with microelements plays prominent role in development of symbiotic apparatus which is confirmed by variation of nitrogen content in the nodules. When comparing with control group, nitrogen content at the phase of full seed ripening due to application of the fertilizers with microelements rose from 0.5 to 0.56 % in the roots, from 1.18 to 1.33 in the vegetative mass, and from 5.76 to 6.41% in the seeds. During crops maturation the nitrogen content increased from 0.40 to 0.52% in the roots, from 1.20 to 1.38% in the hay, and from 5.76 to 6.55% in the grains.
