THE INFLUENCE OF PLANTING DATES AND DOSES OF FERTILIZERS

The determination of optimal timing
for potato planting was studied in numerous
researches. Their main conclusion is the
following: the best term is when soil is heated
to the depth of 10 cm at 7-8°C [1; 2]. At this,
not only general climatic conditions are taken
into account but microclimatic conditions of
the territory, weather conditions and potato
varietal features.
Optimal timing for planting potato is
accompanied by the most favourable
conditions of moisture, warmth, light,
intensity of nutrients that provide productivity
growth [3-5].
According to M. N. Vasylieva [6],
early planting of early-season varieties
contributed to a significant increase of
productivity, whereas at early planting of
middle-late potato varieties the yield, on the
contrary, decreased. The author explains it
that middle-late potato varieties when
planting in early periods at low soil
temperatures germinate weakly and are
exposed to decay comparatively more often
than early-season varieties.
Potato yield losses from diseases and
pests, according to official statistics in
different countries make up a third. The main
reasons for this – viral (5%), bacterial (3%),
fungous (7%) and other diseases.
N. A. Dorozhkin, S. I. Remnieva [7]
indicate that potato tuber lesions with black
scrab sclerotia (fungus Rhizoctonia Solani
Kuhn) is greatly increased with prolonged
stay of tubers on potato haulm after its dying-
off. Experiments of S. M. Tupenevych [8],
F. Ya. Novikov, N. V. Bordukova [9; 10]
found that manure application increased and
fertilizers application – significantly reduced
the number of tubers affected by common
scab.
A number of researchers proved that
for highly efficient use of fertilizers biological
features of varieties and their reaction to the
dose of fertilizer have great importance. The
study of biological features of varieties as for
different fertilizer standards shows that not
only between the varieties of different
maturity groups, but also in the maturity
group there is a difference in the optimal
levels of nutrition. In this regard, the most
efficient and cost-effective dose of fertilizer is
that supplies a separate variety within the
standards and ratios of mineral nutrition [11;
12].
The objective of the work was to
establish optimal conditions for potato
growing, which would increase yields,
reduced thin plantings and their lesion with
diseases.
Materials and methods. Experiments
were conducted during 2003-2005 in 4-field
rotation of the Potato-growing laboratory of
the Institute for Agriculture of Carpathian
Region of NAAS with the following crop
rotation:
1 - green manure crops (winter rape),
2 - potato,
3 - winter wheat,
4 – vetch-oat mixture (for herbage).
The scheme of three-factor experiment
included:
1. Planting periods:
- I period (the earliest possible),
- II period (10 days after the I),
- III period (10 days after the II),
- IV period (10 days after the III).
2. The doses of fertilizers:
- Without fertilizer (control),
- 40 t/ha of manure (background),
- background + N60P60K90,
- background + N90P90K120,
- background + N120P120K180.
3. Potato varieties:
- early-season varieties – Nevska,
Serpanok;
- middle-season varieties – Slava,
Lehenda.
The area of plots of the 1st order
(variety) – 105 m2, 2nd order (levels of
nutrition) – 35 m2.
The area under the experiment – 0.15
hectares, variants placement – randomized.
Mineral fertilizers were applied in the
form of compound NPK fertilizer, lack of
potassium was balanced with potassium
magnesia.
Thus, for potato varieties, depending
on the maturity group, such set of agricultural
practices for potato growing should be
chosen, which provide optimum conditions
for reducing thin plantings and survival of
plants during the growing season.
The infection of potato planting
material depends on the planting timing,
doses of fertilizers and maturity groups of
varieties. The largest (2.8–3.7%) amount of
tubers infected with Rhizoctonia Solani Kuhn
was observed in the variants with early
planting dates. At late planting the reduced
tubers infection with black scab was
observed, along with increased mouldering of
planting tubers from 0.4% to 7.2% especially
for early maturing varieties. Higher tubers
infection (2.2–2.6%) with black scab was
noticed in variants with manure application
(40 t/ha). Application of mineral fertilizers on
manure background had resulted in the
decrease of black scab infection of tubers by
0.8–0.9 %.

Ураження садивного матеріалу картоплі залежить від строків садіння, доз добрив і групи стиглості сорту. Найбільше (2,8–3,7 %) бульб, уражених Phisoctonia Solani Kuhn, відмічено за ранніх строків садіння. При пізніх строках садіння ураження ризоктоніозом зменшується, але зростає загнивання садивних бульб з 0,4 % до 7,2 %, особливо ранньостиглих сортів. Більше ураження бульб (2,2–2,6 %) ризоктоніозом відмічено на варіантах з внесенням гною (40 т/га). З внесенням мінеральних добрив на фоні гною ураження бульб ризоктоніозом зменшувалося на 0,8–0,9 %.
