Irrigation techniques and technology based on principle of regular accumulation of moisture in active layer (surface irrigation, regular sprinkler irrigation) are most common in science and in practice. More progressive is principle of non-stop water supply of plants and soil in conformity to their water consumption. Drip irrigation and impulse sprinkling are based on this principle. The main advantage of drip irrigation is establishment of optimal water and nutritive regime directly in the plant root system. However, such irrigation is not effective enough under conditions of high air temperatures (over 25–35 °С), as growing process of several agricultural plants is known to slow down at 30–35 °С and photosynthesis, consequently, stops, which, in turn, affects plants yielding capacity. Sprinkling irrigation provides improvement of both microclimate in plant's environment and their water regime. Combination of drip and sprinkling irrigation permits the positive characteristics of each individual technology to be united, and to remove a series of disadvantages of their separate use as well as to use drip-sprinkler irrigation technology to create optimal conditions for plant development. Drip-sprinkler irrigation technology facilitates saving of irrigation water through drip irrigation in the main vegetation period and through improvement of microclimate and water regime of agricultural plants with additional sprinkling irrigation within the period of high temperatures and low air humidity that affects the growing process and increases yielding capacity of grown cultures.

In this developing world, saving water is the main problem for agricultural sciences. So, in this field, scientists are using many methods to save water-for instance, traditional irrigation, drip irrigation, sprinkler irrigation, sub-irrigation, and others. Solving irrigation and the problems in this article demonstrated the sub-irrigation method for agriculture plants in the Uzbekistan regions. According to watering theory in the field condition and compared to drip irrigation in the region, scientifically experiment was done. According to the results of the study, this method will automate the stability of soil moisture in the irrigation of agricultural crops: save 4 … 5 times water and prevent soil salinization; the cost of processing plants and fuels and lubricants with the help of technical means is sharply reduced; land use coefficient increases; hardening of crop rows and the number of their processing is sharply reduced; it is guaranteed to increase crop yields by mixing the juice with water; environmental pollution and soil salinity are sharply reduced. In the case of drip irrigation of agricultural crops, flexible plastic pipes with a diameter of 16… 20 mm are laid on the soil near the crop stalks, from which water holes or cracks are formed at certain intervals, from which water drips and irrigates crops. It is also possible to mix the juice of chemical and local fertilizers with water.

The Given

The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth processes are known to slow down and photosynthesis to cease, consequently affecting the yielding capacity. Impulse sprinkling provides optimal moisture level in the given layer, improved microclimate in the plant environment and water regime of plants within the whole vegetation period and is most effective within daytime. Through improvement of microclimate and plants' water regime within periods of high temperature and low air humidity under the conditions of South Kazakhstan, the technology of impulse sprinkling enabled increasing productivity of a clonal rootstock mother plantation for the 3 years of research on average by 19.4% compared to regular sprinkling. The applied technology provided optimization of layers' growth and development conditions upon decrease of the moistening of the soil layer of mother plantation bushes for derogation of their water regime after hilling the grown root layers.

ABSTRACT The development of coffee plant root system changes when subjected to drip irrigation and fertigation. This work aimed to evaluate the effects of different levels of fertigation on the development of coffee root system by drip irrigation in western Bahia. The experiment was carried out with Catuaí Vermelho IAC 144 coffee plants, of about 3.5 years of age, in the “Café do Rio Branco” farm, located in Barreiras - BA, and consisted of a complete randomized blocks design with 3 replicates. Treatments consisted of three levels of nitrogen and potassium fertilization (900/800, 600/500 and 300/250 kg ha-1 year-1 N and K2O), weekly distributed, by means of fertigation, throughout the process. After the fourth harvest, coffee root system was evaluated, and root length density (RLD) and root density (RD) were determined at different sampled layers. The highest root concentration, root length density (RLD), and root density (RD) were observed in the superficial layers of soil (0-20 cm), and under the dripline (30 and 70 cm from the orthotropic branch). Results showed that the lower the N and K2O levels, the higher was the development (RLD and RD) of the coffee root system.

Water is flattering more and more scares and precious resources as population and utilization hike. Elevation of those elements as well as technology and action to support fine water supplies is obligatory to get control of the condition. Agriculture usage of water consumption is almost 70 % of the water used throughout the world and more than half of this water is used for irrigation purpose.For solving the problem of water scarcity in agriculture, it is important to expand water saving irrigation which has become the need of the time. Currently there are varying types of water saving methods include drip irrigation, sprinkler irrigation. Between these irrigation system drip irrigation system is the most successful way in arid and semi-arid areas and its make use of rate can get up to 90 %. Drip irrigation also known as trickle irrigation is a method which minimizes the use of water and filterers by admitting water to drip at a slow and steady pace to the plant root, rather onto the soil surface or openly onto the root zone, a network process of pipes, valves, emitters and tubing.Water is one of the most precocious assets that we have . The level to which water is abundant or hard to get, polluted or clean, advantageous or devastating, deeply effect the size and standard of human life. The relentless elevation in population and the resulting spurt in the request for water and the need to be cautious in organizing and the management of the restricted water resources.

Territories with arid climate are characterized by insufficient atmospheric humidification at high air temperatures. Therefore, the use of drip irrigation during the growing season of plants is an effective agrotechnical method of farming. However, its use causes a number of unfavorable consequences that can be avoided by using biological plant protection agents with pronounced biological activity against phytopathogenic bacteria, micromycetes, insects and viruses. These remedies are based on the introduction of microorganisms and their metabolites into the biotechnological process. A biological plant protection agent based on Bаcillus atrophaeus ACIM В–11474 has been developed and its effect on the mycocenosis of the studied soils when growing lettuce in the arid climate of the Astrakhan region using drip irrigation has been studied.
