For the threshold of vegetation of strawberry plants, the date of establishment of average daily temperatures above 5°C was considered. The weather conditions of the spring period, at the time of the study, were developing successfully for the growth and development of strawberries. At the time of flowering of strawberry plants (end of May to June), there were no recurrent frosts. The flowering phase occurred at the end of May/beginning of June, but taking into account the weather and climatic conditions, preference in the Novosibirsk region should be given to varieties with early and simultaneous ripening of berries.

Figure 1 shows that the period from the beginning of the growing season to the beginning of maturation in all early varieties of large-fruited garden strawberries was formed in the same period equaling 54 to 60 days (60 days for the Tsaritsa variety). No special differences were observed, and during the duration of fruit-bearing, the Honey variety demonstrated a minimum number of days (14 days). The Festivalnaya and Anastasia varieties had a longer fruit-bearing period equaling 25 days. According to the number of harvests, the following varieties showed the maximum values: Festivalnaya and Anastasia (6 harvests), while the minimum number was observed in the Alba variety (3). The rest of the varieties had 4-5 harvests.

Figure 2 shows 47 varieties of medium-ripening large-fruited garden strawberries. The period from the beginning of vegetation to the beginning of maturation had the greatest number of days in seven varieties: Anna, Honeoye, Nancy, Elsanta, Eliani, Bereginya, and Zemklunika (Kupchikha), equaling 68 days. For the Tsarina variety this period equaled 56 days, and for Alyonushka, Dukat, Tanyusha, and Studentskaya it was 59 days. For other varieties, this period ranged from 60 to 65 days. According to the duration of the fruit-bearing period, the medium-ripening varieties of large-fruited garden strawberries were divided as follows. The maximum number of 20 and 21 days was observed in the varieties Tsaritsa, Corrado, Ducat, Xima, Tryufel, Studencheskaya, and Rusich. The minimum number was 12 days in such varieties as Alexandrina, Troitskaya, Nancy, Elsanta, Eliani, and Bereginya. For the remaining varieties, this period ranged from 15 to 19 days.

In this group, for such varieties as Tsaritsa, Anna, Corrado, UniaSmides, Borovitskaya, Rubinovyi kulon, Ducat, Xima, Tryufel, Solovushka, Studencheskaya, Rusich the number of harvests did not exceed five. The minimum number of harvests was observed in such varieties as Alexandrina, Troitskaya, Pervoklassnitsa, Maryshka, Honeoye, Nancy, Eliani, Bereginya, and Kokinskaya zarya, where this value did not exceed three.

Figure 3 shows in late-ripening varieties that the period from the beginning of vegetation to the beginning of maturation is much longer than in early-ripening and mid-ripening varieties of large-fruited garden strawberries. The maximum number of days (78) was observed in the Malvina variety. The minimum number of days (69) was observed in the Alpha and Pineapple varieties. In other varieties, the number of days varied from 70 to 75 days.

Considering the fruit-bearing period, it can be noticed that it was much shorter than in early and medium-ripening varieties. The maximum number of days was 14 and was observed in the Malvina variety, while the minimum number (6 days) was observed in the Vicoda and Pineberry varieties. The remaining varieties on average had a fruit-bearing period from 7 to 10 days.

In varieties in this group, the number of harvests did not exceed three. In the group of remontant varieties of large-fruited garden strawberries consisting of seven varieties (Figure 4), it can be seen that the fruit-bearing period was much longer than in the above-listed groups, and the number of harvests varied from 9 to 13. The largest number (13) was observed in the Ostara variety, in the Selva, Remontantnaya krupnaya, and VimaRina varieties 12 harvests were obtained, in the Albion variety this number equaled 11, in Pink Panda 10, and the minimum number (9) was observed in the Monterey variety.

According to the period from the beginning of the growing season to the beginning of maturation, the varieties were distributed as follows: the maximum number of days (69) was observed in the Pink Panda variety, and the minimum (53 days) was noted in the Remontantnaya krupnaya variety.

The fruit-bearing period in Ostara and Remontantnaya Krupnaya varieties lasted for 85 and 83 days, respectively, in the Selva variety for 23 days, and in the remaining varieties, it ranged from 62 to 75 days.

The yield of large-fruited garden strawberries can be considered as a linear meter, i.e., from 3 plants, and 1 plant. Figures 5-8 show yield graphs from 1 large-fruited strawberry plant.

Figure 5 shows fluctuations in yield in early-ripening varieties of large-fruited garden strawberries. Thus, in the group of early-ripening varieties of large-fruited garden strawberries, the following varieties had the maximum yield: Anastasia and Ballerina, with 104.03 g and 102.89 g, respectively, from 1 plant. The lowest yield was noted in such varieties as Honey (Medovaya) with 57.37 g and Tsaritsa with 54.86 g from 1 plant. On average, the yield of the remaining varieties from this group ranged from 70 to 80 g.

The maximum weight of berries in all varieties was more than 10 g. The maximum weight was noted in the Alba variety (36g), followed by the Festivalnaya variety (26 g), Zefir (22 g), and the minimum weight was noted in the Suzy variety (13.03 g). The remaining varieties' yield varied from 15 to 20 g.

In Figure 6, the following varieties of medium-ripening strawberries showed the maximum yield: Bereginya (147.67 g), Tenira (145.75 g), Vima Kimberly (136.54 g), Asia (131.14 g), Orlets (127.81 g), and UniaSmides (125.98 g). The lowest yield was observed in such varieties as Tanyusha and Honeoye, with 36.74 g and 38.19 g, respectively, from 1 plant. On average, the yield of the remaining varieties ranged from 70 to 90 g.The maximum weight of the berry on average varied from 15 to 22 g from 1 plant, but the group is large, and the spread is large. At the same time, the maximum berry weight was 36 g in the Dukat variety, 34 g in the Asia variety, and 33 g in the Ruslan variety. The minimum weight was 5 g in the Zemklubnik (Kupchikha) variety.

In late-ripening varieties (Figure 7) of large-fruited garden strawberries, the Florace variety had a high yield of 156.78 g per 1 plant. The minimum yield was noted in the Ananasa and Pineberry varieties equaling 18.52 g and 27.49 g, respectively. The remaining varieties had a yield of 70 to 100 g. According to the maximum weight of berries, it is clear that only 4 varieties exceeded 20 g. The maximum weight was observed in the Alpha variety (32 g), Malvina (24 g), Florence (22 g), and Tarda (23 g). The minimum weight was noted in such varieties as Ananasa (4 g) and Pineberry (6 g).

When considering the remontant varieties (Figure 8) of large-fruited garden strawberries, the highest yield was observed in the Remontantnaya krupnaya (425.42 g) and VimaRina varieties (411.27 g per 1 plant), and the lowest one in Monterey (80.7 g). At the same time, the maximum weight of berries in the varieties was observed with a slight difference. Thus, in the Selva variety, it equaled 28 g, in VimaRina 23 g, in Monterey 7 g, and Pink Panda 9 g. The berries of the other varieties were in the weight range from 13 to 17 g.

Based on the purpose of our study to determine the effect of the ripeness group on the yield of introduced varieties of large-fruited garden strawberry, we selected four varieties of large-fruited garden strawberry of different ripeness groups: early-ripening, mid-ripening, late-ripening and remontant. The main indicator of various maturity groups is the yield, which depends on weather conditions and the number of flower stalks formed, and then the commercial-grade berries formed on them [10].

Unlike Rahman et al. [11], our research is consistent with the results of [12, 13] which showed that the introduced strawberry varieties proved to be stable regardless of the maturity group in the ground. When studying the physicochemical properties and methods of cultivation, the quality of fruits changed with the age of the plant and the seasonal cycle of the harvest, and the preferences were similar, both in traditional soil and in groundless culture. In the territory of India, Taiwan, Turkey, and Italy, research is underway on methods of growing strawberries not only on the ground but also in groundless systems [14-16]. Such methods allow harvesting strawberries regardless of weather conditions. Further research, in groundless conditions, can open up new ways for variety introduction. These studies have suggested that the study of our varieties can get a similar result. In this study, the nutritional value and importance of strawberry varieties for human health were determined using advanced analysis methods [17-19]. During our study, minimal damage to plants by diseases and pests was observed.

From this study, we concluded that parasitism is a major health problem for camels because parasites get food and shelter from the host and cause disease. This research shows the high prevalence rate of nematyhelminthes of different species. In this research area, people use camels for meat and draught purpose. This study shows the high attack of gastrointestinal nematyhelminthes on camels and their production is used as food by people. For this purpose, it is suggested that deworming should be done properly after regular intervals with safe hand low cost effective anthelmintic drugs (Albendazole, levamizole and Ivermectin).  Farmers should be educated through the trained team of the Camel Center to assess the aspects of camel health, management and breeding. Due to the high cost of anthelmintic drugs and checkup fees of veterinarians poor owners do not connect with them and destroy the health of animals which causes a huge earning loss.
