The research was based on a 3-year field experiment carried out in south-eastern Poland, in 2013‒2015, on brown, slightly acidic soil. The experiment was established by the randomized subblock method, where the first-order factors were foliar fertilization: (A) Fortis Duotop Zn Mn + Fortis Aminotop, (B) Fortis B Mo + Ferti Agro, (C) Fortis Zn Mn + Fortis B Mo and (0) standard object, without foliar fertilization. The factors of the second order were 4 edible potato cultivars (‘Viviana’, ‘Vineta’, ‘Jelly’ and ‘Agnes’). Foliar application of all fertilizer combinations contributed to the reduction of the content of nitrates and nitrites in potato tubers. However, the response of cultivars to foliar fertilization was varied. The medium late cultivar ‘Jelly’ was characterized by the lowest tendency to accumulate nitrates, while the early cultivar ‘Vineta’ was the highest. The highest content of both nitrates and nitrites in tubers was recorded in the dry year, with a significant shortage of rainfall during the potato growing season, and the lowest in the year, about wet June, and September.

The aim of the study was to determine the effect of foliar fertilizers with the content of macro- and microelements used in the form of chelates on darkening of the tuber flesh of selected potato cultivars. The research was based on a 3-year (2013‒2015) field experiment carried out in Haczów (49°40'N, 21°54'E) on brown, slightly acidic soil. The experiment was based on the method of randomized sub-blocks, where the first order factor was foliar fertilization: Fortis Zn Mn + Fortis Aminotop (A), Fortis B Mo + Ferti Agro (B), Fortis Zn Mn + Fortis B Mo (C) and a standard object without foliar fertilization (0). Second-order factor included four edible potato cultivars of all earliness classes (‘Viviana’, ‘Vineta’, ‘Agnes’, ‘Jelly’). Significant differences in tuber darkening due to foliar application were observed only for tubers 24 h after cooking. The application of Fortis B Mo + Ferti Agro and Fortis Duotop Zn Mn + Fortis Aminotop fertilizers reduced the darkening of the apical part tuber to the greatest extent. Genetic factor differentiated the most the value of all examined traits. The cultivars tested showed varied response to foliar fertilizers.

Abstract A potato experiment was conducted from 2004 to 2006 at the Zawady Experimental Farm. The farm is part of the University of Natural Sciences and Humanities in Siedlce, Poland. Tuber infection and injury by diseases and pathogens of three potato cultivars were assessed according to the potato ridge height and harvest date. The weight of mechanically injured tubers was also determined depending on the potato ridge height and harvest date. The weight of potato tubers infected by fungal and bacterial diseases was influenced by the cultivar, growing season, harvest date, and ridge height. Potatoes grown to their standard height and height ridges, were significantly less infected by diseases at the first harvest date. The weight of tubers in which the tubers were injured by soil pests, was affected by the cultivar and ridge height. Potatoes cultivated in a ridge which was 20 cm high, had tubers with significantly less mechanical injuries compared with a low (16 cm) ridge and high (24 cm) ridge.

The paper presents the results of a three-year exact plot experiment (2008-2010) established in Bałcyny (NE Poland). Three potato cultivars were grown: medium-early &lsquo;Adam&rsquo;, medium-late &lsquo;Pasja Pomorska&rsquo;, and late &lsquo;Ślęza&rsquo;. The experimental factors were foliar fertilizers applied alone or in combination (Basfoliar 12-4-6, ADOB Mn, Solubor DF) and two levels of soil mineral fertilization (N<sub>1</sub>P<sub>1</sub>K<sub>1</sub>-80 kg N × ha<sup>-1</sup>, 80 kg P × ha<sup>-1</sup>, 120 K × ha<sup>-1</sup>; N<sub>2</sub>P<sub>2</sub>K<sub>2</sub>-120 kg N × ha<sup>-1</sup>, 144 kg P × ha<sup>-1</sup>, 156 K × ha<sup>-1</sup>). The experimental materials comprised potato tubers. The symptoms of soft rot (<em>Pectobacterium carotovorum </em>subsp. <em>carotovorum</em>), late blight (<em>Phytophthora infestans</em>) and dry rot (<em>Fusarium </em>spp.) were evaluated in 5 kg potato samples, and were expressed as the percentage mass of infected tubers. The rates of common scab (<em>Streptomyces scabies</em>) and black scurf (<em>Rhizoctonia solani</em>) infection were estimated on 100 tubers collected randomly after harvest, according to a nine-point scale, and were presented as a percentage infection index. In the laboratory, fungi were isolated on PDA medium from potato tubers immediately after harvest and after five-month storage. The incidence of tuber diseases depended on potato cultivars affected. The severity of tuber diseases varied between treatments with two levels of NPK fertilization and foliar fertilization. The lowest number of <em>Fusarium-</em>infected tubers was obtained from treatments where three foliar fertilizers were applied in combination, which was confirmed by the lowest abundance of fungal isolates. More fungi were isolated from potato tubers after harvest than after storage, but pathogens were more frequently isolated from stored tubers. After harvest, the lowest number of pathogenic fungi was isolated from the tubers of cv. &lsquo;Adam&rsquo; in the non-fertilized treatment, and after storage – from the tubers of the late cultivars in the treatment with three foliar fertilizers applied in combination.

A field experiment was carried out in the fields of the Experimental Farm in Zawady owned by the University of Podlasie in Siedlce. An influence of soil tillage methods and herbicides application on the content of glycoalkaloids in edible potato tubers of the Viking cultivar was studied. The results obtained indicated that the content of glycoalkaloids in non-peeled tubers significantly depended on the method of soil tillage and weed control as well as on the research year, whereas in peeled tubers the content significantly depended only on the weather conditions in the growing season. The content of glycoalkaloids in the tubers subjected to the initial treatment (peeling) decreased to 46.81&minus;55.3%, compared to the level of glycoalkaloids before peeling.

В рамках развития органического сельского хозяйства актуально выявление сортов с высокой устойчивостью к вредным организмам. В условиях Удмуртской Республики на дерново-среднеподзолистой среднесуглинистой слабосмытой почве в 2017-2018 годах проводились исследования, целью которых была оценка новых и перспективных сортов картофеля различных по срокам созревания. Одной из задач было выявление повреждений клубней вредителями. Изучали сорта картофеля разных сроков созревания: раннеспелые Нандина, Ред Соня, Колетте, Беллароза, Винета, Джоконда, Раноми среднеспелые Джелли, Вираж, Гала, Рябинушка, Каптива, Алуэт позднеспелые Ред Фентази, Церата КВС, Танго. Полевой однофакторный опыт закладывался согласно методике полевого опыта. Клубневой анализ проводили в соответствии с ГОСТ 33996-2016 Картофель семенной. Технические условия и методы определения качества. Коэффициент адаптивности изучаемых сортов картофеля рассчитан по методу Л.А. Животкова. За два года исследований более урожайными были раннеспелые сорта: Нандина, Ред Соня, Беллароза, Раноми среднеспелые: Джелли, Каптива, Алуэт позднеспелые: Ред Фентази и Церата КВС. Повреждение клубней картофеля личинками щелкуна (проволочником) было очень высоким и составило в 2017 году в среднем по сортам 47, в 2018 году 61. В оба года исследований клубни были повреждены личинками озимой совки (в среднем 3-4 ), личинками майского хруща (1-2 ). В 2018 году наблюдалось повреждение полевками (в среднем по сортам 3 ). Раннеспелые сорта являются более адаптивными к условиям Удмуртской Республики (коэффициент адаптивности 1,22 и 1,31). Однако качество посадочного материала не соответствует ГОСТ по проценту повреждений вредителями. Поэтому необходима тщательная сортировка и доведение клубней до регламентируемых показателей. Для снижения поврежденности в полевых условиях картофель требуется размещать после бобовых и крестоцветных культур, проводить известкование почв и вносить перепревшие органические удобрения.As part of the development of organic agriculture, the identification of varieties with high resistance to pests is relevant. In the conditions of the Udmurt Republic, studies were carried out in 2017-2018 on the derno-medium-soil average carbon-free weak soil, the purpose of which was to assess new and permissive potato cultivars of different maturation times. One challenge was to identify damage to tubers by insect pests and the possibility of using them as planting material. Potato cultivars of different maturation dates were studied: early Nandina, Red Sonya, Kolette, Bellaroza, Vineta, Dzhokonda, Ranomi medium Dzhelli, Virazh, Gala, Ryabinushka, Kaptiva, Aluet late Red Fentazi, Tserata KVS, Tango. Field one-factor experiment was laid according to the method of experimental work. Tuberous analysis was carried out in accordance with GOST 33996-2016 Seed Potatoes. Technical conditions and methods of quality determination . The coefficient of adaptivity of the studied potato cultivars is calculated according to the method of L.A. Zhemkov. More crop-producing were early cultivars: Nandina, Red Sonya, Bellaroza, Ranomi average: Dzhelli, Kaptiva, Aluet late: Red Fentazi and Tserata CF. During the years of research, there was damage to potato tubers by wireworm in 2017 on average 47, and in 2018 61. The only cultivar, Ranomi, was not damaged by the wireworm in 2017. A small number of tubers was damaged by larvae of turnip moth (Agrotis segetum) (3-4) and larvae of white grub (1-2). During two years of research in the Udmurt Republic early cultivars were more adaptive, the coefficient of adaptability was 1,31 and 1,22. However, the quality of the planting material by the percentage of damaged tubers by pests does not comply with state standard. For growing in the region, early cultivars Nandin, Red Sonya, Kolette, Bellarosa, Vineta, Dzhokonda, Ranomi are more suitable from middle cultivars Dzhelli, Kaptiva and Aluet turned out to be more stable from late ripening Red Fentazi. Due to severe damage by insect pests, especially wireworms, careful sorting and bringing tubers to regulated parameters, liming of soils, and introduction of rotted organic fertilizers are necessary, as well as to place potatoes in crop rotation after legumes and cruciferous crops.

Field experiment was conducted at National Horticultural Research Institute (NIHORT), Mbato Sub-station, Okigwe, Imo State, South-eastern Nigeria in the 2012 and 2013 cropping seasons to establish the most appropriate time to introduce component crops in cocoyam/cowpea mixture. Five different planting schemes (two and four weeks before, two and four weeks after and same day) and two cowpea genotypes (climbing Akidienu and erect IT97K-499-35) were used. The component crops were grown in monocultures to assess the productivity of the systems. The experimental design used was a completely randomized design with three replicates. Growth and yield of cocoyam and the cowpea genotypes increased significantly (P<0.05) when either of the component crops was planted earlier than the other. Intercropping reduced significantly (P<0.05) cocoyam yield by 0.7 − 74% in IT97K-499-35 and 22 − 80% in Akidienu. Sowing the cowpea genotypes the same day or before cocoyam resulted in over-yielding of cowpea, whereas sowing Akidienu and IT97K-499-35 after cocoyam caused pod yield reductions of 64% − 73% and 32% − 59% on average, respectively. Cocoyam planted two weeks before IT97K-499-35 produced more satisfactory yields of the intercrops than the other planting schedules with LER, LEC and ATER of 2.15, 1.03 and 1.57, respectively.

Dessureault-Rompré, J., Zebarth, B. J., Burton, D. L. and Georgallas, A. 2015. Predicting soil nitrogen supply from soil properties. Can. J. Soil Sci. 95: 63–75. Prediction functions based on simple kinetic models can be used to estimate soil N mineralization as an aid to improved fertilizer N management, but require long-term incubations to obtain the necessary parameters. Therefore, the objective of this study was to examine the feasibility of predicting the mineralizable N parameters necessary to implement prediction functions and in addition to verify their efficiency in modeling soil N supply (SNS) over a growing season. To implement a prediction function based on a first-order (F) kinetic model, a regression equation was developed using a data base of 92 soils, which accounted for 65% of the variance in potentially mineralizable N (N 0) using soil total N (STN) and Pool I, a labile mineralizable N pool. However, the F prediction function did not provide satisfactory prediction (R 2=0.17–0.18) of SNS when compared with a field-based measure of SNS (PASNS) if values of N 0 were predicted from the regression equation. We also examined a two-pool zero- plus first-order (ZF) prediction function. A regression model was developed including soil organic C and Pool I and explained 66% of the variance in k S , the rate constant of the zero-order pool. In addition, a regression equation was developed which explained 86% of the variance in the size of the first-order pool, N L , from Pool I. The ZF prediction function provided satisfactory prediction of SNS (R 2=0.41–0.49) using both measured and predicted values of k S and N L . This study demonstrated a simple prediction function can be used to estimate SNS over a growing season where the mineralizable N parameters are predicted from simple soil properties using regression equations.

The field experiment on identifying differences in the effect of the herbicide and foliar feeding of plants with liquid nitrogen fertilizer (UAN-32) against the background of autumn tillage with a cultivator or plow on potato yield and phytopathologic characteristics of tubers during storage was carried out in 2019-2020 in the Nizhny Novgorod region. The experiment was laid on sod-podzolic sandy loamy soil in production conditions on two varieties of potato ‒ the super-early Сolomba variety and the medium-early Innovator variety grown for seeds. The variants under study were surface application of the soil herbicide Gezagard in a tank mixture with UAN-32 and foliar feeding of plants with UAN-32 (N42) during the growing season against the background of N42P42K169 (calcium chloride in autumn + ammonium nitrate phosphate in spring). The results indicate that the background fertilization provides the yield of Colombа variety potato of 20.7-29.0 t/ha, the Innovator variety – 17.4-23.1 t/ha. The use of the herbicide is more effective during autumn tillage with a cultivator, providing an increase in yield of 28-37 % on both potato varieties, feeding of plants with UAN-32 contributes to an increase in yield (8-10 %) only on the Сolomba variety. Plowing the soil for potatoes helps to avoid the pest damage of tubers and to reduce their susceptibility to rhizoctonia by 6-27 %, to wet rot ‒ up to 55 %. In general, it has been established that due to autumn plowing with fertilization at a dose of N42P42K169, it is possible to obtain an increase in potato yield exceeding the increase provided both by herbicides and the use of foliar feeding of potatoes.
