EFFECTIVENESS OF USING MICRONUTRIENT FERTILIZERS AND HUMIC PREPARATIONS IN TREATMENT OF PISUM SATIVUM SEEDLINGS
The effect of micronutrient fertilizers and their combination with humic preparations in treatment of Pisum sativum in vegetation period has been studied on the leached chernozem of Ryazan region. Trial establishment, observation, assessment and estimation were carried out according to the methodical guidelines of B.A. Dospehov Examination of roots was carried out in compliance with the method of N.Z. Stankov. Photosynthetic activity indices were determined by the method of A.A. Nimirovich. Mathematical processing of the experimental data was carried out by using correlation, regression and dispersion analysis methods. The obtained results have shown positive influence of the preparations being examined on the production processes of Pisum sativum. Reduction in the duration of vegetation period has been observed, as well as improvement of biometric characteristics of the plants and increase in activity of nodule bacteria. Thus, having been treated with humates and micronutrients, the seedlings demonstrated increase in the quantity of nodules by 41,77%; having been treated with only micronutrients - by 18,73%. The analysis of the crop yield structure has demonstrated positive influence on all the essential indicators: height and weight of the plants, quantity of beans, number of productive nodes, weight of 1000 seeds. Improvement of qualitative characteristics of pea has also been observed. Application of micronutrient fertilizers has provided an increase in protein content by 3,65%; using it in combination with humic preparation Ecorost - by 7,34%. The authors see the potential for implementation of the studied preparations into production on a large scale, since they enable to improve the main economic indicators of cultivating Pisum sativum. The highest indices of economical efficiency were registered when using humic preparations and micronutrient fertilizers in combination. When this method used, the return from 100 ha increased by 105,9 thousand rubles, and the production efficiency - by 7,70%.
