The purpose of the research was to study the effect of mineral fertilizers and plant protection system on the vegetation index NDVI and its seasonal dynamics in agrocenoses of spring barley with overseeding of perennial grasses in the North-West of Russia. The data obtained indicate that against the background of the deficiency of the main elements of mineral nutrition in the second half of the growing season of spring barley, a significant phytomass of perennial grasses is formed in the crop, which account for 36.7%. This leads to a smaller decrease in the NDVI index (by 0.06) than in the fertilized variants (0.20). The value of NDVI index reflects not only the state of cultivated plants and weed infestation of crops, but also the level of development of crops, growing under vegetation. The influence of mineral nutrition developed during the period of maximum values of the index, which were recorded 6-8 weeks from the sowing date and 26-30 weeks from the beginning of the year. Under the influence of average doses of fertilizers, the NDVI index increased by 0.09...0.2 (on average 0.13), under the influence of high doses – by 0.13...0.26 (on average 0.18). The influence of plant protection system was expressed by a decrease in the phytomass of weeds (by 49.4...68.9%), at the same time the mass of spring barley and perennial grasses increased (by 1.7...18.5% and by 11.7...43.5% respectively). Carrying out the whole complex of protective measures led to a decrease in the NDVI index values by 0.01...0.06, depending on the phytosanitary situation in the agrocenosis. The most reliable forecast of the yield of spring barley can be implemented in the period from 5 to 7 weeks from the beginning of the emergence of barley shoots, especially against the background of the use of plant protection products that eliminate the influence of harmful organisms on the formation of the crop and the optical properties of crops

The authors analyzed the biological effectiveness of the integrated plant protection system formed when the microbiological fungicide BisolbiSan, Zh was included in the classical protection scheme adopted in the farms of the Rostov region. The biological effectiveness of the integrated protection system, including the fungicide BisolbiSan, was analyzed, the impact of the studied protection system on the yield, the quality of the grain obtained, the phytosanitary condition of the crop during the growing season on winter wheat crops of the variety Nakhodka with the use of a plant protection system, including the fungicide BisolbiSan, Zh. The fungicide BisolbiSan, containing a culture of rhizospheric bacteria Bacillus subtilis strain H-13, suppresses the germination of spores and mycelium growth of phytopathogenic fungi due to the multilateral action of bacterial metabolites, without causing the formation of resistance in pathogens. It was found that the protection system used practically does not cause a decrease in grain quality — in terms of the average protein and gluten content, the grain at the experimental site even slightly exceeds the grain obtained from the control site by 16.88% and 27.8%. With the cost of winter wheat grain of 1100 rubles/kg, an increase in the yield in the experiment of 3.8 kg/ha in relation to control and the cost of an experimental protection system in the amount of 3,357 rubles/ha, revenue amounted to 823 rubles/ha.

Plant Protection System

The systematic use of foliar fertilizers during growing season is a relatively new agronomic practice in Central Russia and it is still not widely used in horticultural enterprises of the region. One of the main reasons for this is the relatively high cost of this method. Producers prefer soil fertilization which adversely affect the environment. A significant reduction in cost of foliar fertilizing could be obtained by combining foliar nutrition with plant protection. The number of plant protection treatments, as well as toxicity of some products, is increasing annually. The use of fertilizers and plant protection products negatively affect the environment. It is very important to find ways of decreasing this load on surroundings. Currently, many different biological preparations for plant protection exist which are suggested to replace chemicals. The problem is in their relative low effectiveness compared to traditional plant protection products. The authors have studied the most popular plant protection products (in a traditional protection system) and application of foliar fertilizers (in a mineral foliar fertilizer system) in comparison with ecologized plant protection system (based on bacterial and low-toxic preparations) in tank mixtures with seaweed extracts-based foliar fertilizers. The authors have considered yield, scab development, content of calcium in leaves and fruits as the main criteria of this study. The research was carried out in the irrigated orchard (1,480 trees/ha), planted in leached meadow-chernozem soil. The investigation was carried out in 2013-2015. The results of traditional plant protection system in tank mixtures with mineral foliar fertilizer application, as well as ecologized products with seaweed extracts-based preparations, have been compared. Traditional plant protection system in combination with mineral foliar fertilizers have ensured a higher content of calcium in leaves and fruits, less damage from scab and higher yields. We can consider two ways of replacing traditional plant protection and fertilizing approach: the development of new highly efficient ecologized products or increased financial support.
