Covering Material

In the Moscoww region, frosts are quite probable to return until the fi rst decade of June. To protect potatoes from the returning cold weather, it is possible to use a temporary covering material in the “planting – seedling emergence” period. The authors have studied the use of covering materials on early potato varieties of Udacha, Zhukovsky early, Red Scarlet, Snegir’, and Meteor. Studies have been conducted on the test plot of the Vegetable Growing Department of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy in 2017-2019. Non-woven white and black material of the same density of 17 g/m2 was used for covering. No covering was used in the check variant. The cultivation technology was standard,it included tillage (plowing, spring tillage, and cutting ridges before planting), as well as plant care (inter-row cultivation and hilling-up). Planting was carried out with a single-row potato planter. The earliest emergence of seedlings was observed under white covering material with a diff erence of 5-6 days in relation to the check variant. In the variant with a black covering material, the diff erence averaged 3-4 days. Due to covering, planting was carried out earlier than expected and the crop was formed by July 15. The interphase period between potato planting and seddling emergence decreased, while that from seddling emergence to harvesting increased, consequently, the yield increased by 11.6…14.7%. The maximum yield was obtained with the Red Scarlet variety using the white covering material, the minimum – in the check variant without covering. The same trend is typical for other varieties. It has been established that covering with any material has a positive eff ect on the duration of the potato growing season and the yield by increasing the period of tuberization. Covering allows getting early potato varieties 2 weeks earlier in the Moscow region.

Loading And Unloading

The permittivity of potato tissue was studied during uniaxial compression of cylindrical specimens prepared from two early varieties. Both the real and the imaginary permitivity components were determined repeatedly during the loading and unloading tests. The analysis of the results obtained shows that small differences exist between the permittivity of the late and early potato varieties. The differences are concentrated mainly at frequencies higher than 1 kHz with a maximum between 10 and 100 kHz. The effect of deformation is concentrated into frequencies between 1 and 100 kHz. The effect of deformation on the permittivity values can be divided into reversible and irreversible parts. The results obtained in the loading/unloading tests give some more information on the proportion of both parts.

The article presents the yield of early potato varieties, considering the different planting rates of tubers. A two-factor field experiment was conducted in 2013 - 2015 at the experimental field of the Perm State Agro-Technological University named after Academician. The purpose of the research is to find ways to cultivate early-ripening potato varieties to obtain a yield of 35 t/ha. The soils of the experimental site are sod-finely podzolic medium loamy. The humus content is 1.9 - 3.2%, pH (KCl) 4.4-5.1, P2O5 185-300 mg/kg, K2O 143-431 mg/kg. The meteorological conditions of the growing seasons were opposite in terms of weather conditions and did not equally affect the yield. It was found that, on average, over three years, the goal of the experiment was achieved only in one variant of the experiment - in the Rosalind variety with a maximum thickening of 71.4 thousand tubers per hectare. The limit of thickening in the Red Scarlett variety was at the maximum thickening of tubers when planting 71.4 thousand. The limit of thickening of the Luck variety was 47.6 thousand tubers, the limit of compaction of plantings in the Rosalind variety was 57.1 thousand tubers.

Выявлена положительная реакция на раннюю посадку (до 1,6 т/га или 4,1%), загущение посадок (2,4 т/га или 7,3%), проращивание семенных клубней (5,2 т/га или 13,1%). Ранняя посадка пророщенных клубней обеспечила прибавку урожая в размере 7,1 т/га или 18%, а условный доход – 87,6 тыс. р/га.Experimental data for a range of economically-valuable traits of early potato varieties Varyag are given. A positive reaction to the early planting (up to 1.6 t/ha or 4.1%), compacting planting (2.4 t/ha or 7.3%), germination of seed tubers (5.2 t/ha or 13.1%) is ascertained. Early planting of couched tubers provided the harvest increase amounting to 7.1 t/ha or 18%, and conditional income 87600 r/ha.
