Abstract:
This article provides information about the varieties of watermelon grown in our
republic, the cultivation of early watermelon varieties, and several intensive methods for
extending the period of consumption of fresh watermelon products throughout the year by the
population, and establishing watermelon consumption earlier than usual throughout the year.

Watermelon crops are thermophilic, as they originate from South Africa. Watermelon
seeds begin to germinate at +14-16 °C. When the temperature drops below this, the seeds rot in
the ground and rarely germinate. Therefore, watermelon crops cannot be planted too early -
before the ground warms up. The optimal temperature for seed germination is +20 °C. The
temperature can fluctuate around +15-32 °C during the day. At such a temperature, seedlings
will begin to appear 5-6 days after sowing. A decrease in temperature delays the germination of
seedlings. The optimal temperature for watermelon growth and development is +25-30 °C. If
the temperature drops to +12-15 °C, the flowers of the crops fall off, they stop growing and
gradually dry out. 0 °C or -1 °C completely destroys the seedlings of watermelon crops. If the
temperature drops to +3-5 °C, even adult plants are damaged. Despite the fact that watermelon
is an extremely thermophilic plant, it is not very resistant to heat. The protein in the leaves

coagulates at +45-50 °C. However, since the transpiration process in watermelon is extremely
intensive, the plant cools down.
This increases its heat resistance to some extent. 47 varieties of watermelon are zoned in
the State Register of the Republic of Uzbekistan, of which 15 are local, the rest are foreign
varieties. Currently, such varieties of watermelon as Shirin, Sharq ne'mati, Dilnoz, Ko'ziboy,
Holler, L-64, Miramir are grown in the territories of our Republic. To obtain a bountiful and
high-quality watermelon crop, it is necessary to use seeds with a variety of at least 99% and
germination of at least 90-95%. Before planting, the seeds are soaked in a 5% solution of table
salt. As a result, the dark and large fractions of the seeds sink under water, and the small and
immature seeds float to the surface. The seeds that remain under water are removed, rinsed in
clean water and dried until the moisture evaporates. Heating the seeds at +40-50 °C for 4-5
hours increases the resistance of the seeds to diseases, as well as the number of mother flowers,
which has a positive effect on increasing the yield.
To increase the germination capacity of the seeds, it has been scientifically proven that
soaking them in a 0.5-1.0% solution of copper sulfate for 1 hour before sowing increases the
yield by 13-14% and seed germination by 8.7%. Methods for extending the period of
consumption of fresh watermelon products by the population of our republic throughout the
year:
1. Using various methods of growing a fairy-tale product.
2. Introduction of late-ripening varieties suitable for longer storage and improvement of storage
methods.
There are several intensive methods for extending the period of consumption of fresh
watermelon products throughout the year by establishing the consumption of watermelons
earlier than usual throughout the year. Methods of growing early watermelon products include
mulching the soil, planting the crop from seedlings, planting seedlings and seeds under
temporary film covers, and growing in protected heated and unheated greenhouses.
There are several intensive methods for extending the period of consumption of fresh
watermelons throughout the year and establishing the consumption of watermelons earlier than
usual throughout the year. The methods of growing early watermelons include mulching the
soil, planting the crop from seedlings, mulching seedlings and seeds under temporary film
covers, and growing in protected heated and unheated greenhouses.
The first method is mulching the soil. Mulching is carried out simultaneously with
sowing seeds or after sowing. In this case, a film is covered over the rows of crops and its edges
are covered with soil. After the emergence of the crop, holes are made in the film so that the
plants can emerge from the surface. The plants are left on the film throughout the entire
growing season and removed after the harvest. In this method, the crop is sown one to two
weeks before the date of planting in open ground. Mulching the soil with seedlings also gives
you the opportunity to get a fabulous product.
The most effective way to accelerate watermelon cultivation is to plant the crop from
seedlings in open ground, this is the second method, and most of our farmers use this method.
The resulting trenches are covered with a white film as mulch. The film is perforated every 70
cm. Phosphorus fertilizer is diluted in the perforated areas. To prepare the diluted phosphorus, 2
kg of amorphous fertilizer is added to 10 liters of water, boiled and dissolved. The prepared

solution is mixed in 10 liters of water and poured into each hole at the rate of 1 liter. 100 kg of
phosphorus fertilizer is used per hectare of area. 7100 seedlings are planted per hectare.
The third method. Mulching from seedlings under a temporary film-cover. For growing
under temporary film-covering, early-maturing, short-stemmed, disease-resistant varieties of
watermelon are used. Specially prepared 35-45-day-old seedlings are planted and covered with
a single-layer polyethylene film. Immediately after planting seedlings in the ground or sowing
seeds, it is necessary to begin installing a film cover in the form of a tunnel. A strip with an
irrigation furrow running through the middle of each tunnel covers two rows of crops. The
width of the tunnel is 160-180 cm, the height is 60-70 cm, and the length (50-60 m)
depending on the conditions.
The space between the strips is 180-190 cm, which is left open and serves as a corridor.
Later, the plant's foliage is placed in this corridor.
The fourth method - when 30-35-day-old seedlings are planted in areas cleared of grain, the
crop is harvested no later than late autumn. Late varieties have a long shelf life after harvesting.
In the first method, the crop is harvested in the third decade of June, in the second method in
the first half of June, and in the third method in the third decade of May. In the fourth method,
which is planted in a repeated period, the fruits ripen in the third decade of September and are
harvested in bulk. Of course, the ripening period of the fruits varies depending on the weather,
soil conditions, planting dates, and the early or mid-ripening of the varieties.
