Considerable Damage

The use of chemical pesticides in agriculture demands high investments; its in discriminated and inadequate application to obtain immediate crop response has caused considerable damage to the environment and human health, either due to a direct effect or indirect contamination of farmer fields and water sources by highly toxic products. On the other hand, as a result of soil fertility losses, farmers move to new areas for farming, causing a complex migration phenomena and devastation of natural forests. In an effort to find new alternatives for the management of crop pests compatible with the environment and agro-ecologically friendly, some technologies recently developed have been offered to small Andean potato farmers. Among these, the recycling of organic residues and the management of natural soil microorganisms which are important alternatives to reduce the importation and use of toxic agro-chemicals as well as to preserve and recuperate soil fertility and thus reach a sustainable potato production by Andean farmers. This will not only guarantee food security, but will also have favorable impact on the yield and quality of potato and other crops.Accepted for publication: December 28, 2011

Abstract. The purpose of the research was to study the effect of fertilizer rates depending on drainage and weather conditions on the yield and quality of potatoes, their payback with an increase in yield. Methodology and methods of research. The studies were conducted in a two-factor field experiment in 2012–2020, factor A – drainage (drained by closed potter drainage and non-drained soil), factor B – various fertilizer rates (without fertilizers; multi-purpose compost (KMN) 10 t/ha + K90; KMN 10 t/ha + N70K180). The soil of experimental plot of sod-podzolic light loamy are predominant, well-cultivated. Potatoes were cultivated according to the ridge technology developed at VNIIMZ, the predecessor of winter grain crops. According to weather conditions, the years of research are divided into excessively humid, humid and arid. Analyses and observations were carried out according to the generally accepted methods of experimental work, calculations using statistical analysis. Results. The tendencies of changes in the indicators of the water-air regime of the arable layer of soil (moisture, total porosity, porosity of aeration, bulk density) depending on drainage and weather conditions were revealed. The influence of fertilizer rates on drained and non-drained areas, depending on weather conditions, on the content of mineral nitrogen in the soil, yield and its structure, the quality of potato production (content of nitrates, starch in tubers), the use of photosynthetically active solar radiation, payback of fertilizers by an increase in yield has been established. The share of the influence of fertilizers and drainage on the variability of the yield in different weather conditions has been determined. Scientific novelty. The share of the participation of the studied factors in the variability of the potato yield and the rational rates of the use of fertilizers, depending on soil and weather conditions, have been established.

Limited Application

Yield and quality of forage mainly depend on the floristic composition, ie the share of higher quality grasses and legumes, soil fertility, amount and distribution of precipitation and light. Natural meadows and pastures are the most important resource in the forage production in the hilly and mountainous area of Republic of Serbia. Despite the large areas, the forage production on natural grasslands is relatively low. Limited application of a small number of agrotechnical measures is the main reason for low and unstable yields and poor forage quality. Only by appropriate fertilization of meadows and pastures with mineral and organic fertilizers, their rational exploitation, it is possible to achieve an increase in hay yield by several times and improvement in forage quality, simultaneously.

Aim. To study the specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, yield and quality of winter wheat grain compared to granular nitrogen fertilizers in order to elaborate intensive produc- tion technologies. Methods. The content of mineral nitrogen in the soil was determined according to DSTU 4729-2007, the content of movable phosphorus and potassium forms − by Chirikov’s method (DSTU 4115- 2002). The abundance of the main ecological and trophic groups was registered after sowing the soil suspen- sion on dense nutrient media. The concentration of total nitrogen, phosphorus, and potassium in plant samples was determined according to the measurement procedure 31-497058-019-2005. The quality indices of grain, i.e. protein and crude fi ber content as well as general glassiness were determined using Inframatic 8600 NIR analyzer, Perten Instruments AB (Sweden). Results. The specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, the use of nutrients from fertilizers and soil, the yield and quality of winter wheat grain were demonstrated. Conclusions. The advantages of anhydrous ammonia application prior to sowing compared to the use of ammonia nitrate, traditional for Ukrainian agriculture after the growing season, were established.

The work aims to study the effectiveness of herbicides application on potato varieties of different ripeness groups in the conditions northern forest-steppe of the Novosibirsk Ob region. The authors obtained experimental data on leached chernozem in Novosibirsk district, Novosibirsk region, in 2017-2019. In their studies, the authors used common elements of potato cultivation tech- nology. The general background for potatoes in autumn fertiliser was applied at a dose of P60K90. Nitrogen fertilisers were used at a rate of 60 kg/ha in spring under pre-sowing cultivation. Herbicides Gezagard, Lazurit, Zenkor, Boxer, and mixtures of individual herbicides were applied before and after sprouting when potato plants were up to 12-14 cm high. Herbicides significantly reduced the infestation of potato varieties Lubava (early) and Tuleevsky (medium-season). The authors showed that the use of herbicides accelerated the processes of growth and development of potato varieties of two groups of ripeness. There was a significant increase in leaf area, photosynthetic potential, and 23-28% plant productivity. On a background of herbicides increase of yield by 30-35% is observed. There was an increase in the marketability of tubers by 10%. Used herbicides provided good quality and preservation of potato production. The authors note that the double application of herbicides Zenkor and Lazurit offers high rates of weed reduction. Thus yield and quality of presentation have high indicators. In tubers of potatoes, the residual quantity of herbicides is not detected. Application of herbicides economically and energetically practical. The level of profitability exceeds control 1,4 times on a background of double spraying by herbicides Zenkor and Lazurit.
