Sweet Million

varieties using drip, surface, and hybrid irrigation methods,
combined with three NPK ratios (1:1:1, 1:0.5:1.5, and 1.5:1:1). The highest yield and fruit quality
were achieved under drip irrigation with phosphorus and potassium-rich nutrition. The method
proved economically efficient by reducing water consumption and improving Brix, salinity, and
external appearance of fruits. Practical recommendations were developed for smallholder farmers.

Today, in greenhouse vegetable growing, along with ensuring high yields and quality
indicators, the need for the use of resource-saving technologies is growing. In particular, rational
use of water and mineral fertilizers is of great importance in reducing production costs and
ensuring environmental sustainability.
Cocktail-type tomato varieties are a salty, small-sized, highly export-oriented product, and for their
high-quality and efficient cultivation, it is necessary to develop a correct irrigation and feeding
strategy. The development of these varieties in a greenhouse environment is very sensitive, and
water shortages or nutrient imbalances can negatively affect fruit set, salinity levels, appearance,
and overall yield.
Therefore, determining the most effective and resource-saving feeding and irrigation system by
comparing irrigation types (drip, overhead, hybrid) and different NPK ratios is of great importance
for practice. This approach, while improving product quality, allows for the introduction of
economically viable technologies for small and medium-sized farms.
The main objective of this study is to assess the effectiveness of feeding and irrigation regimes in
the cultivation of cocktail-type tomato varieties in greenhouse conditions, to determine the
relationship between water consumption and crop quality, and to develop scientifically based
recommendations for practice.
Methods. The study was conducted in an intensive greenhouse with polycarbonate covering
in the Tashkent region during the 2024–2025 season. Two types of cocktail tomato varieties
were selected as the objects - Sakura F1 and Sweet Million. These varieties are distinguished
by their high yield, fruit quality, and high demand in the consumer market.
•
Irrigation methods used in the experiment:
•
1. Drip irrigation (intensive method)
•
2. Sprinkling (traditional) irrigation
•
3. Hybrid method (drip + periodic sprinkling irrigation)
•
The amounts of three types of mineral fertilizers were determined differently in the feeding
regimes:
•
• NPK 1:1:1 - standard nutrient balance
•
• NPK 1:0.5:1.5 - regime with a predominance of phosphorus and potassium
•
• NPK 1.5:1:1 - regime with a predominance of nitrogen
•
In total, 3 (irrigation) × 3 (feeding) = 9 experimental variants were created. Each variant
was repeated 3 times, and each repetition was studied based on a sample of 10 plants.
•
During the experiment, the following agrobiological and technological indicators were
determined: The amount of fruit obtained from each plant (kg/m²);
• Fruit quality indicators (Brix %, salinity, appearance);
• Water consumption (liters/m²);
• Overall economic efficiency of each option.
The harvest was measured at the end of the growing season and the quality of the fruit
was assessed in laboratory conditions based on chemical analysis.
•
Research results. A clear definition of irrigation and feeding strategies in greenhouse
tomato cultivation is one of the main factors determining yield and product quality. Cocktail-type

tomatoes are in high market demand, and their cultivation technology, in particular, the efficient
use of water and fertilizers, increases the economic efficiency of farms. Below is a scientific
analysis of the yield and quality indicators of the Sweet Million and Sakura F1 varieties grown
under different irrigation and feeding regimes based on the results of the experiment conducted in
2024–2025 (see Tables 1 and 2).

This table compares the yields of the two varieties under three different irrigation and nutrient
regimes. The highest yield of 12.1 kg/m² was recorded for the Sweet Million variety under drip
irrigation and 1:0.5:1.5 NPK regime. Sakura F1 also yielded 11.6 kg/m² under the same
conditions. This indicates that fruit set is higher
in a regime rich in phosphorus and potassium.On the contrary, the yield decreased significantly
under the traditional irrigation method (ditch) and the standard 1:1:1 NPK regime: 8.7 kg/m² for
Sweet Million, 8.2 kg/m² for Sakura F1. This method does not save water, and moisture is
retained in the soil for a long time, which can lead to a lag in development and a decrease in fruit
quality.
The hybrid method (drip + ditch) showed an average yield of 10.3 (Sweet Million)and 9.5
(Sakura F1) kg/m². This method distributes water evenly, but the high efficiency is lower than
that of the drip method.

The second table shows the brix (sugar content), external value of the fruit and water
consumption. With drip irrigation, 6.5% (Sweet Million) and 6.4% (Sakura F1) brix levels were
determined. This is an important indicator of the taste and exportability of the product. With the
drip method, the brix level drops (5.8 and 5.7%), which indicates that due to excess water, the
fruit is juicy, but has a poor taste.
As for the external value of the fruit, varieties grown by the drip and hybrid methods have a high
fruit structure and color, that is, marketable. Increased moisture in the drip method sometimes
causes injuries or deformities in the fruit.

As for water consumption, the drip method gave the highest results with the lowest water
consumption (120–125 l/m²). The ditch method requires 180–185 l/m² of water, which means
that about 40–50% more resources are used, but the result is lower.
The hybrid method, while maintaining water consumption at a moderate level, did not give much
effect. Although this method combines both approaches, it was noted that it was less effective
than drip irrigation in terms of water saving and quality.

1.
Based on this table, it is clear: drip irrigation provides advantages not only in water saving,
but also in quality and yield. The ditch method has the highest water consumption and low
efficiency. The hybrid method is considered an intermediate option, but cannot fully ensure
quality.
2.
The results of the study once again confirmed the importance of implementing effective
irrigation and feeding technologies for cocktail-type tomato varieties in greenhouse conditions. In
particular:
3.
1. Sweet Million and Sakura F1 varieties showed high yield and quality indicators under
drip irrigation conditions. At the same time, the yield increased to 11.6–12.1 kg/m², and the Brix
content in the fruit was 6.4–6.5%. This puts them among the promising varieties with high
economic efficiency.
4.
2. The NPK 1:0.5:1.5 feeding regimen — a formula rich in phosphorus and potassium —
had a positive effect on fruit structure, taste, and overall development. Fruit set was high in this
regimen, and appearance was also highly rated.
5.
The irrigation method
Along with the increase in water consumption during irrigation, a
decrease in yield and quality indicators was observed. Water consumption increased to 180–185
l/m², the Brix content of the fruit decreased, and the appearance was assessed as “average”. This
method leads to inefficient use of water resources and an increase in the cost of the product.
6.
6. The hybrid method - that is, a combination of drip and ditch methods - has average
efficiency and is recommended only if the conditions are met on large areas. However, as a general
conclusion, it was shown that it is less effective than the drip method.
7.
In the future, it is advisable to develop an individual feeding and irrigation strategy based
on the agrobiological characteristics of each cocktail tomato variety, and optimize the amount of
microelements, organic and mineral substances that stimulate fruiting during the care process. This
will serve
not only to increase yield, but also to increase product quality.
8.
Also, selecting fruit varieties with high Brix content, appearance, and storage capacity and
developing export-oriented technologies for them are promising areas.
