Freeze Protection

Three irrigation treatments (none, drip, and sprinkler) and eight rowcover treatments were evaluated for their capacity to provide freeze protection for strawberries (Fragaria ×ananassa Duch.) in a split-plot factorial field experiment. The period under study included 20 freeze events, two events with minima of -9.5C and -10.0C. With no freeze protection, up to 93% of the flowers were damaged by freezes. Among sprinkler-irrigated plants, an average of only 10% flowers were damaged due to the freezes. Heavy-weight rowcovers (polyethylene blanket and polypropylene, 30 and 50 g·m-2, respectively) protected strawberry flowers as well as sprinkler irrigation to -4.4C. Early yield (December-January) from unprotected plants was negligible. Early yields from plants protected with a 3.2-mm polyethylene blanket or a 50 g·m-2 polypropylene cover were equal to yields obtained with sprinkler-protected plants. Combinations of sprinkler and certain rowcover treatments provided for better fruit production than either treatment alone. Drip irrigation alone provided no protection from freezes. All strawberry plants recovered from freeze damage and total-season yields were similar with all irrigation methods and rowcovers.

In recent years, livestock farms in the Astrakhan region have mainly used grasses from natural hayfields and pastures for fodder. But, due to the sharp aridization of the climate, and, as a consequence, the more frequent droughts, as well as the unregulated growth of the number of animals on farms, the reserves of natural herbage are often insufficient. Therefore, the region began to increase the area of sown hayfields for irrigation. The aim of the work is to study the effect of various irrigation methods on the productivity of cereal-leguminous mixtures with multi-cut use in the conditions of light chestnut soils of the Northern Caspian region. The studies were carried out in 2017-2020 in the Astrakhan region. All studied irrigation methods (sprinkler irrigation, drip irrigation with a belt laying depth of 0.0, 0.15, 0.25, 0.35 and 0.45 m, periodic flooding), with the exception of subsoil irrigation, with an ordinary method of sowing contributed to the development of both cereals and legumes. In these variants of the experiment, cereals occupied a significant part in the total herbage - from 40.0 to 61.0%. When using the spread sowing method, only in one variant, the share of cereal grasses was 54.0% (periodic flooding). In all others with this method of sowing, the amount of cereals in the total mass was insignificant, or they were completely absent. The widespread method of sowing was also the most productive in all the years of research. The maximum yield in the experiment was noted in all variants of the experiment in the third year of the life of grasses in 2019.The highest productivity with the spread method of sowing was noted in 2019 in the variants of the experiment with a belt laying depth of 0.25, 0.35 and 0.45 m and amounted to 98.1, 104.4 and 111.0 t/ha, respectively. In the variants with the row-sowing method, the yield was lower than with the wide-spread one. The highest yield with this method of sowing was also noted in 2019 in variants with subsurface drip irrigation with a belt laying depth of 0.35 and 0.45 m and amounted to 105.5 and 104.8 t/ha, respectively

Microirrigation is an important component of citrus production systems in Florida. For citrus trees, microirrigation is more desirable than other irrigation methods for several reasons: water conservation, fertilizer management efficiency, and freeze protection. Research has shown that when microirrigation systems are properly managed, water savings can amount to as much as 80% compared with subirrigation and 50% compared with overhead sprinkler irrigation. Research has also shown the important advantage of microsprinklers for freeze protection of citrus. This 4-page fact sheet discusses fertilizer solubility and some common fertigation materials. It also offers a fertigation summary.

The objective of this research was to compare different irrigation methods based on a parametric evaluation system in an area of 16,350 ha in the Albaji Plain of the Khuzestan Province, in the southwest of Iran. The soil properties of the study area such as texture, depth, electrical conductivity, drainage, calcium carbonate content and slope were derived from a semi-detailed soil study carried out on the Albaji Plain on a scale of 1:20,000. After the soil properties were analyzed and evaluated, suitability maps were generated for surface, sprinkler and drip irrigation methods using a geographic information system (GIS). The results demonstrated that by applying sprinkler irrigation instead of surface and drip irrigation methods, the land suitability of 14,530 ha (88.87%) of the Albaji Plain could be improved substantially. However, the main limiting factors in using surface and sprinkler irrigation methods in this area were heavy soil texture, drainage and salinity, and the main limiting factors in using drip irrigation methods were heavy soil texture, calcium carbonate and salinity.

Strawberry anthracnose caused by Colletotrichum acutatum is often asymptomatic on plants in sprinkler-irrigated nurseries but destructive after transplantation into fruiting fields. This study evaluated the impact of strawberry nursery sprinkler and drip irrigation in the presence or absence of C. acutatum on post-transplantation plant growth, mortality, and fruit yield in fruiting fields in California. In a 2005 nursery at Tulelake, CA, dip infestation of mother plants with C. acutatum reduced early-season mother plant canopy size by 21% and delayed runner production in mother plants but otherwise had no obvious disease symptoms. In comparison with sprinkler-irrigated treatments in the nursery, drip irrigation of infested nursery plots reduced plant losses in fruit production fields by 86% at Watsonville, CA, in 2005 and 50% and 75% at Oxnard, CA, in 2005 and 2008. Transplants from infested nursery treatments had a 33% to 60% smaller canopy and 11% to 42% lower yield than transplants from uninfested nursery treatments. However, transplant canopy size and yield from the infested and then drip-irrigated nursery treatment were similar to the sprinkler-irrigated, non-infested nursery treatment. Quantitative polymerase chain reaction measurements of C. acutatum in crown tissue of fruiting field plants seven weeks after transplanting showed significantly more C. acutatum (≈11×) in their crowns in sprinkler-irrigated than drip-irrigated, infested nursery transplant treatments. During the course of fruit production, the amount of C. acutatum in crown tissue increased in all treatments. However, at the end of the fruit season, there was still significantly more (≈8×) C. acutatum in the crowns of the plants produced by sprinkler irrigation than by drip irrigation in the nursery. These data suggest that if C. acutatum is present in the nursery, drip irrigation can reduce subsequent plant stunting and yield losses in strawberry production fields.

Background: Potato (Solanum tuberosum) popularly known as ‘The King of Vegetables’, has emerged as fourth most important food crop in the world after rice, wheat and maize. Indian vegetables basket is incomplete without potato as its, dry matter, edible energy and edible protein makes it nutritionally superior as well as staple food throughout the world. Methods: The experiment during 2016-2018 was laid out in factorial randomized complete block design with three replications to study the effect of bed size on the yield and size of the tuber under different irrigation methods. Results: Maximum yield was obtained in 60cm bed (narrow bed size) whereas in irrigation system drip produced maximum yield. All quality parameters did not influence due to sowing method and irrigation system but chip recovery was more in drip irrigation than furrow system. Maximum yield through interaction was found in drip irrigated 105 cm triple row bed. Around 45-50 per cent water was saved through drip irrigation as compared to furrow irrigation. However, maximum benefit cost ratio was obtained in furrow irrigated 60cm bed size.

Relevance. The water regime is one of the main processes in the life of the plant, optimizing which can increase the yield of cultivated crops. In protected ground conditions, the plants' water needs are met exclusively by irrigation. Irrigation is the most important means of increasing the yield of greenhouse crops, including tomato. Greenhouse tomatoes are very demanding on soil moisture, as well as on air humidity. To combat overheating of the air and plants, and to increase the relative humidity of the air in greenhouses, plants for evaporative cooling and humidification of plants are successfully used, which are especially effective in drip irrigation. The combination of drip irrigation with evaporative cooling makes it possible to control the water regime of the soil and air habitat of plants.Materials and Methods. The purpose of the research: to identify the most optimal method of water supply for greenhouse tomatoes. The research was conducted in 2018-2019 in the greenhouse complex "Yugagroholding", located in the suburbs of the city of Makhachkala. The object of research was a hybrid of tomato Mei shuai. The experiments included three options: sprinkling, drip irrigation, and drip irrigation with evaporative cooling.Results. The comparative characteristics of irrigation methods by yield are presented, the results of which indicate the advantage of the second and third options over sprinkling: the highest yield was obtained in the third option and amounted to 14.7 kg/m2 . The best methods of water supply that ensure the optimal water regime of greenhouse tomatoes are identified-drip irrigation and drip irrigation in combination with evaporative cooling, the latter is the best in most indicators.

Although water-saving measures are increasingly being adopted in orchards, little is known about how different irrigation methods enhance water use efficiency at the root system level. To study the allocation of water sources of water absorption by cherry roots under two irrigation methods, surface irrigation and drip irrigation, oxygen isotope tracing and root excavation were used in this study. We found that different irrigation methods have different effects on the average δ18O content of soil water in the soil profile. The IsoSource model was applied to calculate the contribution rate of water absorption by cherry roots under these irrigation methods. During the drought period in spring (also a key period of water consumption for cherry trees), irrigation water was the main source of water absorbed by cherry roots. In summer, cherry roots exhibited a wide range of water absorption sources. In this case, relative to the surface irrigation mode, the drip irrigation mode demonstrated higher irrigation water use efficiency. After two years of the above experiment, root excavation was used to analyze the effects of these irrigation methods on the distribution pattern of roots. We found that root distribution is mainly affected by soil depth. The root system indexes in 10–30 cm soil layer differ significantly from those in other soil layers. Drip irrigation increased the root length density (RLD) and root surface area (RSA) in the shallow soil. There was no significant difference in root biomass density (RBD) and root volume ratio (RVR) between the two irrigation treatments. The effects of these irrigation methods on the 2D distribution of cherry RBD, RLD, RSA and RVR, which indicated that the cherry roots were mainly concentrated in the horizontal depths of 20 to 100 cm, which was related to the irrigation wet zone. In the current experiment, more than 85% of cherry roots were distributed in the space with horizontal radius of 0 to 100 cm and vertical depth of 0 to 80 cm; above 95% of cherry roots were distributed in the space with the horizontal radius of 0 to 150 cm and the vertical depth of 0 to 80 cm. Compared with surface irrigation, drip irrigation makes RLD and RSA more concentrated in the horizontal range of 30–100 cm and vertical range of 0–70 cm.

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.
