ABSTRACT 

The article offers the findings of a scientific study on the most suitable times to plant early-ripening potato cultivars in 

the northern districts of the agrobiocenosis of Karakalpakstan. 

KEYWORDS 

Early maturity, variety, growth, development, air temperature, relative humidity, optimal dates. 

INTRODUCTION

It is vital to consider the unique features of the 

Republic of Karakalpakstan's agroclimatic conditions in 

order to achieve a high yield from agricultural 

products. It is known that the rising air temperature 

had a negative impact on the early commencement of 

planting periods since the growing season is slightly 

constrained and spring arrives later than usual. The 

protocols have demonstrated that while planting early-

ripening potato varieties and harvesting seedlings, it is 

imperative to follow suggestions with scientific 

backing. The reason for this is that the best planting 

times and recommended early-ripening potato types 

for these agroclimatic conditions are yet unknown. 

To solve the current problem of planting early ripening 

potato varieties suitable for the region's agroclimatic 

and soil conditions, as well as to determine the optimal 

dates, special research in the conditions of the 

northern districts of the region is required in order to 

scientifically substantiate the problem. 

RESEARCH MATERIALS AND METHOD 

Planting early ripening varieties of potatoes and 

carrying out agrotechnical measures was implemented 

based on the methods of B.J. Azimov, B.B. Azimov [6], 

V.I. Zuev [7], T.E. Ostonakulov, Sh [8].

Scientific research analysis and results: Regarding the 

agroclimatic conditions of Karakalpakstan, the 

guidelines for figuring out when to plant early-ripening 

potato types indicate that the winter months bring a 

little chilly air temperature and freezing of the top 80–

110 cm of soil. It should be noted that during the spring 

and fall seasons, the average daily air temperature 

remains consistently above 10°C from April 6–12 to 

October 14–16. In the northern regions of the territory, 

the temperature is below 0°C for 120–140 days, and in 

the south for 90–100 days. 

The fact that early varieties of potatoes have a 

vegetative period of 80–90 days and are a plant that 

yields its maximum amount when agrotechnical 

measures are applied under appropriate agroclimatic 

circumstances is one of the unique qualities of 

potatoes related to bioecological development. 

The examination of the findings from the plant 

research indicates that the air temperature fluctuates 

between being slightly lower and slightly higher during 

the tuber ripening process because the potatoes are 

acclimated to the early planting of the early varieties. 

Additionally, the air temperature is higher during the 

mid-early varieties' planting and ripening periods. 

Research findings have been drawn with the 

consideration that it is slightly lower [3, 4, 5, 9]. 

In the research on figuring out the best times to plant 

early and mid-early potato types, the tubers were 

planted from the third ten days of March (23–27.03.) in 

consideration of the conditions of the northern parts 

of the Republic of Karakalpakstan. The second period 

was planted during the first ten days of April (04-07.04) 

and the second period (14-15.04.) respectively. The 

agrotechnical operations conducted during the growth 

season followed the guidelines suggested for 

application in agroclimatic conditions. 

A planting pattern of 70x30 cm was used for the potato 

types, and 47–48 thousand bushes were planted per 

hectare. During the investigation, rainfall rates, 

average daily air temperature, and relative humidity 

were considered and assessed. 

is thought to be one of the key elements in the 

germination of planted potato varieties. The average 

air temperature over the research years was 1.7–12°C at 

the end of March, 10.3–12.8°C at the beginning of April, 

and 14–17.2°C at the end of the year. The reason is that 

during this time, the temperature of the top 0–20 cm 

of soil rose to 16–22°C, which triggered the growth of 

the planted potato kinds. 

The germination of seedlings and the growth of roots 

and stems were considered to be active during the 

period when the plants were planted on March 3rd and 

during the first ten days of April in the performed 

research (Table 1).

Phenological observations were conducted in order to identify the best times to plant potatoes. These observations 

included a study of the phases from the formation of full sprouts of different potato plant varieties in the experimental 

fields to the full drying of the palak, which signifies the ripening of the crop, and their significance in relation to the 

standard. 

n comparison to the conventional Zarafshan variety, the overall yield of potato varieties planted in the first ten days 

of April increased by / to 4.3 t/ha for the Romano variety, 4.2 t/ha for the Sante variety, 3.3 t/ha for the Zafira variety, 

and 2.5 t for the Dosimpalak variety. The end of March and the first 10 days of April are the best times to plant, 

according to an analysis of the productivity of the cultivars based on planting season (Table 2).

The highest yield when studied in the years in which 

the varieties of early and mid-early potatoes planted 

under conditions of high agro – climate were studied in 

2018 – in the varieties Doisimpalak (20.9 ca) and Impala 

(20.6 ca), In 2019 – Romano (21.4 ca), Sante (21.3 ca) 

and Zafira (20.4 ca ), and in 2020-Sante (19.3 ca), while 

dosimpalak (18.9 ca) and Zafira (18.8 ca) varieties had, 

the lowest total yield was observed in evolution and 

Impala varieties in 2018-2020 and when planted in 

planting deadlines. 

CONCLUSION 

It was discovered through research conducted in the 

Republic of Karakalpakstan that planting dates have a 

considerable impact on the production of different 

potato cultivars. Planting early-ripening potato 

varieties under local conditions should take place 

between the third week of March and the end of the 

first week of April. It is advised to plant potato varieties 

Evolution, Fresco, Dosimpalak, Arnova, Picasso, 

Zarafshon, Kuvonch-1656 M, Umid-2, Tuyimli, Surkhon-

1, Zafira, Romano, Sante, and Impala in the third and 

second weeks of March and April, respectively, using 

agrotechnical methods that take the local air 

temperature and relative humidity into account.
