Several production nurseries were surveyed about techniques used to reduce water usage and runoff. The nurseries surveyed used from 400,000 gallons of water per day to 5,000,000 gallons of water per day during peak usage. Water availability and the potential for nitrate runoff from large production nurseries to contaminate the environment have resulted in requirements by regulatory agencies to decrease water usage and runoff. Nurseries have complied by using techniques such as drip irrigation, subirrigation, pulsing, recycling, and computer controlled irrigation systems. The use of techniques such as recycling and “better management practices” have resulted in significant decreases (approximately 30%) in water usage.

Water quality has become a significant issue in the nursery industry. Local testing of runoff contamination from nursery production is, however, of little value to other growers because of the variation in management practices and nursery layouts. Two nursery blocks have been designed and constructed to test runoff from production with sprinkler and drip irrigation systems in combination with constant liquid fertilization and controlled release fertilizers. Management practices using various combinations of irrigation systems with fertilizer application rates are being tested in a small area with reasonable control of inputs. Preliminary data has shown no difference in plant response to irrigation method, but runoff was significantly reduced with drip irrigation. Plant quality was better with controlled release fertilizer, which generally yielded less N and P contamination in runoff, than constant liquid fertilization except during extremely hot weather.

<p>Sustainable agriculture should be based on management practices that improve resource usage efficiency and minimize harmful impacts on the environment while maintaining and stabilizing crop production. Both tillage and irrigation can have a great influence on hydrological processes within agroecosystems. However, it remains difficult to directly assess the effect of practices on water fluxes which has been mainly indirectly quantified by complex numerical modelling methods in the past. Therefore, the objective of the study was to use a space for time concept and measure oxygen and hydrogen isotopes (δ<sup>18</sup>O, δ<sup>2</sup>H) in the pore water of soil profiles as well as moisture contents for quantifying the soil water balance and fluxes. Covering all combinations, soil profiles and isotope analysis was performed for 16 sites planted with winter wheat and managed with different tillage (conventional tillage (CT), reduced tillage (RT), minimal tillage (MT), and no-tillage (NT)) and irrigation systems (hose reel boom irrigation with nozzles (BI), sprinkler irrigation (SI), drip irrigation (DI) and no irrigation (NI)). The results indicated that the more intense the tillage, the lower the water content. Among the irrigation systems, DI had the highest average water content. Tracing the minimum in the isotopic composition of the pores water within the depth profiles showed a deeper percolation of water in the CT fields, which indicates higher water flow velocity. Considering both water content and differences in water flow velocities resulted in water fluxes ranging from 90 to 151 mm yr<sup>-1</sup>. The losses due to evapotranspiration varied between 57 and 80%. The resulting evapotranspiration within tillage and irrigation variants decreased in the order RT>CT≈MT>NT, and SI>BI>DI>NI. Thus, the method revealed that the lower water content in CT fields is a consequence of deeper water infiltration. Moreover, irrigation water contributed mostly to evapotranspiration, and drip irrigation showed the lowest evapotranspiration losses among irrigation systems. This study demonstrated that water stable isotopes can be used as indicators and are a promising method to quantify water fluxes in agricultural fields with great potential for evaluating management practices.</p>

Subsurface Drip

In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high water tables are one of the most inefficient methods of irrigation, though some irrigation management practices can contribute to better soil moisture uniformity. Subsurface drip irrigation systems apply water below the soil surface by microirrigation, improving the water distribution and time required to raise the water table for seepage irrigation.

Amino Acid Concentrations

The concentrations of amino acids and volatile compounds of a given grapevine cultivar may be modified by climate variability between years and by management practices, such as irrigation, that may alter the typicality of its wines. The current study aimed at assessing the amino acid profile of musts and wines, volatile composition and sensory profile of wines from Vitis vinifera (L.) cultivar Godello under rain-fed and two drip irrigation systems (above, drip irrigation (DI), and under the soil surface, subsurface drip irrigation (SDI)) over three consecutive years. Irrigation tended to increase must and wine total acidity; however, it did not alter must amino acid concentrations significantly. Irrigation reduced the concentrations of acetaldehyde and methanol in Godello wines. Moreover, irrigation tended to decrease the concentrations of compounds giving fruity aromas, such as acetaldehyde (by 31% in SDI) and isoamyl acetate (by 21% in SDI), when compared to rain-fed conditions. Sensory analysis revealed slight differences between treatments. Rain-fed and SDI were the treatments showing the greatest differences. Weather conditions affected more must and wine composition than in-season effects caused by irrigation.

HighlightsSubsurface drip irrigation (SDI) has continued to expand in irrigation area within the U.S. during the last 15 years.Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, and turf).SDI usage on many crops has matured through research and development of appropriate strategies and technologiesDespite some persistent challenges to successful use of SDI, important opportunities exist for further adoption.Abstract. Subsurface drip irrigation (SDI) offers several advantages over alternative irrigation systems when it is designed and installed correctly and when best management practices are adopted. These advantages include the ability to apply water and nutrients directly and efficiently within the crop root zone. Disadvantages of SDI in commercial agriculture relative to alternative irrigation systems include greater capital cost per unit land area (except for small land parcels), unfamiliar management and maintenance protocols that can exacerbate the potential for emitter clogging, the visibility of system attributes (components and design characteristics) and performance, and the susceptibility to damage (i.e., rodents and tillage) of the subsurface driplines. Despite these disadvantages, SDI continues to be adopted in commercial agriculture in the U.S., and research efforts to evaluate and develop SDI systems continue as well. This article summarizes recent progress in research (2010 to 2020) and the status of commercial adoption of SDI, along with a discussion of current challenges and future opportunities.

Cotton plants require sufficient water availability, especially during germination and growth and dry conditions at harvest. In drip irrigation, irrigation can be adjusted to the water needs of each type of plant that varies depending on the growth phase and the type of plant. The study aims to determine the growth and production of cotton plants that use drip irrigation systems in two different planting seasons. The study was conducted for 2 (two) consecutive years, the first study: planting using drip irrigation was carried out in August 2017 and continued with the second planting in May 2018. The research was conducted in Turucinnae Village, Lamuru District, Bone Regency, South Sulawesi Province. The research was carried out in the form of field experiments in the form of a demonstration plot using an experimental design and analysis carried out to find out and explain the implementation of drip irrigation in two different planting seasons. Vegetative growth of cotton plants that use drip irrigation in 2017 provides better results than in 2018 seen from plant height and number of leaves, while the production of cotton plants using drip irrigation in 2017 is greater than that planted in 2018 in terms of the number of bolls. Formed and weight of cotton produced.

Abstract: To study on different type of irrigation system suitable for south region of Maharashtra. We are attempting to find an irrigation system which would require less water and will be economical with higher yield of the crops for which it is installed. Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. There are many types of irrigation systems, in which water is supplied to the entire field uniformly Study of various types of irrigation method's such as surface irrigation, subsurface irrigation, drip irrigation and smart irrigation. We discussed about the different types of irrigation systems, there are several types of irrigation systems such as surface irrigation, sub-surface irrigation, drip irrigation, IOT, smart irrigation, sensor based irrigation in combination of traditional and modern type of irrigation. From above study we came to know the difference between automated irrigation system and manual irrigation system. We will know that automated irrigation system gives higher yield of crops using less amount of water as compared to manual irrigation system in accordance to automated and manual. Our study is to compare our system with other irrigation systems in terms of economy and optimum water usage to provide maximum results.

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.
