Farmers’ Approaches to Drip Irrigation Applications and the Factors Affecting the Utilization from Drip Irrigation Subsidies: Case of Adana and Niğde Provinces

In this study, the socio-economic structure of the agricultural enterprises that utilized from the in-field drip irrigation subsidies or not, were determined, a comparative analysis of their knowledge levels and opinions about drip irrigation method was made in Adana and Niğde provinces. Besides, the factors affecting the benefit of the producers from drip irrigation subsidies were determined. A survey was conducted with a total of 26 producers, 10 of which utilized from drip irrigation subsidies in Adana and 16 of which utilized from drip irrigation subsidies in Niğde. In order to make a comparison between the groups, a survey was conducted with the same number of producers who did not utilize from drip irrigation subsidies. In the analysis of the data, basic descriptive statistics such as mean, standard deviation and percentage calculations were used. The continuous data obtained were subjected to the t test and the discrete data to the chi-square test to determine whether there was a difference between the producers who utilized and did not utilize from drip irrigation subsidies. Tendency of the producers to utilize from drip irrigation subsidies was determined using binary logistic regression analysis. It was determined that the age of the producers, the number of family members, their non-agricultural income and the type of activity they were engaged in affected the drip irrigation subsidies negatively, while the education period, the size of the irrigated land and the number of family members working in agriculture had a positive effect. Considering that the purpose of drip irrigation subsidies is to ensure more effective use of limited water, to increase productivity, to reduce labor and production costs, and to increase the prevalence of drip irrigation systems, it is possible to say that drip irrigation subsidies was applied in accordance with its purpose.

Effects of Automated Irrigation Systems and Water Regimes on Soil Properties, Water Productivity, Yield and Fruit Quality of Date Palm

Applications of modern micro-irrigation methods are inevitable for optimum water use due to the limitations imposed by irrigation water resource scarcity. Regardless of water shortages and associated challenges in dry areas, the irrigation of date palm trees consumes an excessive quantity of water annually using conventional irrigation methods. Therefore, the present study was designed to evaluate the effects of modern surface and subsurface micro-irrigation systems, i.e., subsurface drip irrigation (SSDI), controlled surface irrigation (CSI), and surface drip-irrigation methods (SDI), with different irrigation water regimes, i.e., 50%, 75%, and 100% irrigation water requirements (IWRs), on the yield and fruit quality of date palms (cv. Khalas) and water conservation in the dryland region of Al-Ahsa, Saudi Arabia. The effects of three irrigation methods and IWRs were studied on macronutrients and soil chemical properties at three depths (0–30, 30–60, and 60–90 cm), as well as on water productivity, yield, and the fruit quality of date palms. The study was carried out over two years and was designed using a two-factorial randomized complete block design (RCBD) with nine replications. The results indicated that electrical conductivity (EC) increased as the depth of the soil increased. The soil chemical properties did not change much in all experimental treatments, while soil pH values decreased with the soil depth from 0–30 to 60–90 cm. Although the maximum fruit yield (96.62 kg palm−1) was recorded when 100% irrigation water was applied in the SSDI system, other treatment combinations, such as SDI at 100% IWR (84.86 kg palm−1), SSDI at 75% IWR (84.84 kg palm−1), and CSI at 100% IWR (83.86 kg palm−1) behaved alike and showed promising results. Similarly, the highest irrigation water productivity (2.11 kg m−3) was observed in the SSDI system at 50% IWR, followed by the SSDI at 75% IWR (1.64 kg m−3) and 100% IWR (1.40 kg m−3). Fruit quality attributes were also promoted with the SSDI system at 75% IWR. Hence, the SSDI method at 75% IWR appeared to be an optimal choice for date palm irrigation in arid areas due to its positive impact on water conservation and fruit characteristics without affecting soil chemical properties.

Productivity and Profitability of Indian Mustard (Brassica juncea L.) Influenced by Drip Irrigation and Micronutrient Application Methods

A field experiment was conducted in split plot design with drip irrigation levels (0.4, 0.6 and 0.8 IW/CPE ratios) in main plot and micronutrient application methods (control, soil, foliar and fertigation) in sub plot during season at S.K.N. College of Agriculture, Jobner Rabi (Rajasthan) during 2018. The scheduling of drip irrigation at 0.8 IW/CPE ratio recorded significantly higher plant height, dry matter accumulation, siliquae per plant, seeds per siliqua, test weight and seed yield over 0.4 IW/CPE ratios, which was statistically at par with 0.6 IW/CPE ratio. Drip irrigation at 0.8 IW/CPE ratio recorded higher monetary value. Among micronutrient application methods, fertigation significantly increased plant height at 80 DAS and at harvest, dry matter accumulation at all growth stages, siliquae per plant and seeds per siliqua, seed yield over all other application method. Higher net return and B: C ratio also under fertigation.

Effects of Different Mulches and Fertilizers under Two Irrigation Methods on Garlic Yield and Soil Properties

ABSTRACT Successive use of sand on the soil surface during garlic planting process facilitates clove sprouting and prevents soil crust formation. However, this process has led to the destruction and damage of the soil structure and texture in the East Azerbaijan province, northwest of Iran. In this study, the effects of different organic mulches and irrigation methods on soil properties and garlic yield were investigated. Experiments were conducted based on the split-plot design with three replications. The treatments consisted of two surface and drip irrigation methods, while seven types of mulches (straw 1.5 kg m−2, cow manure in two quantities of 2 kg m−2 and 4 kg m−2, sand in two quantities of 4 kg m−2 and 8 kg m−2, poultry manure 1.5 kg m−2, polyethylene mulch) and no mulch as a control treatment were used. The use of poultry and cow manures increased the average yield of garlic to 18.51 and 20.92 ton ha−1, respectively, as compared to the sand mulch case (11.5 ton ha−1). The results of this study showed that the use of cow manure and poultry manure can increase soil fertility and better garlic yield. Moreover, the use of drip irrigation method instead of surface irrigation method, besides maintaining soil characteristics and consuming fewer water levels, was increased the average yield of garlic from 14.19 to 16.67 ton ha−1.

Establishing Seeded Tall Fescue with Covers and Drip Irrigation Methods

The use of covers may improve establishment of seeded turfgrass but their use in combination with drip irrigation techniques has not been evaluated. We investigated the effects of two cover types and three irrigation methods on establishment of seeded tall fescue turfgrass. For spring seeding of tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], turf establishment was successful with subsurface drip irrigation (SDI) and aboveground drip irrigation (AGD) in fine textured soil in the transition zone. With SDI, AGD, or sprinkler irrigation, both polyester mesh (Poly) and straw blanket (Straw) covers improved turf establishment in the order of Poly > Straw > No Cover, but turf establishment in Poly and Straw became similar over time. Soil surface temperature averaged higher in Poly (14°C [57°F]) than Straw (9.5°C [49°F]) and No Cover (8.6°C [47.5°F]) during the first 12 days after seeding when covers were installed. Results indicate that covers improved spring establishment of seeded, cool-season turfgrass in a fine-textured soil and in a US transition zone climate by mitigating low temperature extremes and reducing erosion during rainfall. Establishment was similar between drip (SDI and AGD) and sprinkler irrigation, but the use of protective covers is recommended when establishing turfgrass from seed.

Pakistan faces surface water and groundwater shortage which are the main reason for assessing more appropriate method of irrigation water use. Subsurface drip irrigation plays an important role to conserves irrigation water and enhances crop yields by reducing surface water evaporation in Pakistan. Two years (2019-20) trials were carried out at “Water Management Research Center” (WMRC), Mansoor Malangi road Faisalabad, under randomized complete block design (RCBD). Maize (Zea mays L.) hybrid variety “YH-1898” was selected for this experiment with sandy loam soil. Sub-surface drip laterals were buried manually at different depths of 0.15, 0.25 and 0.35 m. The results of subsurface drip irrigation for crop water productivity and maize grains yield were compared with surface drip and gravity irrigation methods (furrow-bed and furrowridge). The outcomes showed that maximum grain yield (8753 and 8860 kg/ha) was achieved in both the seasons in 2019 and 2020, respectively under sub-surface drip irrigation installed at a depth of 0.15 m. Similarly, the results of water productivity also revealed that the highest water productivity (2.074 and 2.085 kg/cm3 ) was concluded both the years in 2019-20, respectively under subsurface drip irrigation installed at a depth of 0.15 m. It is concluded that maximum grain yield and water productivity can be accomplished by the installation of sub-surface drip laterals at 0.15 m depth for maize crop in a semi-arid region of Pakistan.

Four different land plots with 8 ha total area have been explored to evaluate the physicochemical and ameliorative state of uncultivated soils in the subzones of Araks riverside. The physicochemical properties of the soil samples, chemical composition of water extract, content of water-soluble salts and available nutrients have been studied. It is recommended to conduct physicochemical and agrochemical evaluation of the fallow soils in order to include them in the agricultural activities. Besides, ameliorants should be introduced in weakly salinized soils, greenhouse farms should be established in poor soils, while the irrigation should be implemented only through drip and sprinkling irrigation methods.

Effects of Drip Irrigation and Cultivation Methods on Establishment of Seeded Tall Fescue

Subsurface drip irrigation (SDI) is becoming increasingly popular for maintaining turfgrass, in part because it conserves water. However, turf managers considering SDI may wonder if SDI is effective in establishing seeded turfgrass, should the need arise. Also, can verticutting or core aeration be used to establish the seedbed without damaging the buried driplines? Is one of those two cultivation methods better than the other? These questions were evaluated in this study. An aboveground drip irrigation system (AGD) was also evaluated because it has been suggested as a portable method for establishing turfgrass planted along roadsides.

Effects of drip irrigation and cultivation methods on establishment of seeded tall fescue

AbstractSubsurface drip irrigation (SDI) may save water but its effectiveness in establishing seeded turfgrass across different soil types and climates requires further investigation. This study was conducted in fine‐textured soils near Manhattan, KS. Our objectives were to investigate establishment of seeded tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] using: (a) SDI, aboveground drip irrigation (AGD), and overhead sprinkler irrigation (OH); and (b) core aeration vs. verticutting for seedbed preparation. Irrigation was applied daily at 150% reference evapotranspiration (ETo) as follows: OH, three times (3×) daily at 50% ETo per irrigation; AGD, 3× daily at 50% ETo per irrigation; SDI, one time (1×), two times (2×), and 3× daily at 150, 75, and 50% ETo per irrigation, respectively. Additional frequencies/amounts were included with SDI because it was unknown how soil hydraulic conductivity would affect uniformity of surface wetting and seed germination. Establishment was evaluated with green cover (GC), visual turfgrass quality (TQ), and normalized difference vegetation index (NDVI). Establishment was faster with SDI than AGD or OH, and similar between AGD and OH. By the end of the 1st month after seeding, GC and NDVI were up to 25 and 15% greater, respectively, in SDI than AGD and OH. In SDI, establishment was fastest when water was applied 2× vs. 3× or 1× d–1. Cultivation effects were negligible, indicating seedbed preparation with either method is appropriate as long as depths of cultivation and driplines are considered to avoid SDI damage. Results indicate seeded tall fescue turfgrass can be established with SDI in fine‐textured soils in a transition zone climate.

Hydrological Drought Analysis for Bolu City with Streamflow Drought Index

Hydrological drought refers to the decrease in the amount of water found in surface or groundwater resources and monitoring of this natural disaster is very important due to causing serious problems in drinking and irrigation water supply and hydroelectric energy production. In this study, hydrological drought analysis was made for two streams in Bolu city located in the Western Black Sea Region in the north of Turkey and 3, 6 and 12 month streamflow drought indices were calculated by using the Streamflow Drought Index method. For this aim, the streamflow data of Bolu stream - Beşdeğirmen and Ulusu - Afatlar streamflow monitoring stations were used. According to the results, extreme and severedroughts were determined for two stream flow stations and it is seen that drought periods varied between 1 and 9 years. The most severe and longest droughts were detected for Bolu stream - Beşdeğirmen station. Mild droughts are much higher than moderate, severe and extreme droughts. It has been observed that the severity and number of drought for Bolu stream - Beşdeğirmen station have increased in recent years. In order to reduce the effects of hydrological drought, hydrological drought should be monitored continuously and necessary precautions should be taken regarding the management of water resources. People should be informed about water consumption and so waste should be prevented. Interms of irrigation water, drip irrigation method should be used instead of flood irrigation or sprinkler irrigation methods. For this aim, farmers should be made aware of this issue. Alternative renewable energy sources or other energy sources should be used for reductions in hydroelectric energy production.

Effect of Performance of Water Stashes Irrigation Approaches on Selected Species of Plant’s Water Productivity in Urban Rooftop Agriculture with Respect to Climate Change

Urbanization and population growth have led to urban areas with a substantial concrete surface compared to adjacent rural areas, creating challenges regarding fresh food, water security, and the need for agricultural land. Climate change affects the rainfall pattern and ground water in urban areas, so the gradual growth of urban rooftop agriculture (URTA) is an increasing trend for the owners of residential buildings. URTA is increasing in the form of private initiatives, but without consideration of efficient water management techniques and application of other related inputs. URTA differs substantially from traditional agriculture in terms of sunshine, thermal regime, the moisture dynamics of a concrete roof top, etc. Considering these aspects of URTA, an effective, efficient, science-based and economically viable irrigation method is necessary to popularize this approach and consequently increase the productivity of crops. With this in mind, the drip irrigation method is considered for the cultivation and determination of water productivity for selected species of plants such as the Bottle Gourd, Tomato, Chili, and Brinjal in the URTA, which was also compared to the traditional irrigation approach. This is why groundwater and green (grey and rain) water were considered as the source of irrigation during the dry season, based on the daily crop evapotranspiration and moisture content of the plant growing medium. For this reason, ET0 of the selected crops was measured using the CROPWAT 8.0 model. The results of this study revealed that the optimum irrigation water requirement of any crop in URTA is around 54% access (ETc), and 46–64% of access irrigation water is used by the traditional method compared to the drip irrigation method. The study reported that with drip irrigation with potable water, the yield was increased by 21.43–22.40% and rain and grey-water also increased yield by 31.87–33.33% compared to container and traditional pipe irrigation. It was also found that the water qualities of mixed water (grey and rainwater) are in an acceptable range limit for irrigation. As a result, urban planners, city dwellers, and researchers can formulate appropriate plans to cultivate different species of plants through this water saving irrigation method using green water, and should explore the concept of water-smart URTA technologies as organic inventions embedded in these results.

Establishing seeded tall fescue with covers and drip irrigation methods

AbstractThe use of covers may improve the establishment of seeded turfgrass but their use in combination with drip irrigation techniques has not been evaluated. In this study, repeated twice in the spring of 2020 near Manhattan, KS, we investigated the effects of two cover types and three irrigation methods on the establishment of seeded tall fescue turfgrass [Schedonorus arundinaceus (Schreb.) Dumort.]. Turfgrass cover types included (a) polyester mesh, (b) a straw blanket, and (c) no cover as a control. Irrigation treatments were (a) subsurface drip irrigation, (b) aboveground drip irrigation, and (c) overhead sprinkler irrigation (control). Measurements of green cover, ground and drone‐based normalized difference vegetation indices, and visual turfgrass quality ratings indicated that establishment was improved with both cover types compared with uncovered plots, in the order polyester > straw > uncovered in both trials, but polyester and straw became similar over time. The soil surface temperature averaged higher in polyester (14 °C) than in straw (9.5 °C) and uncovered (8.6 °C) plots during the first 12 d after seeding when the covers were installed. The results indicate that covers improved the spring establishment of seeded, cool‐season turfgrass in a fine‐textured soil and in a U.S. transition zone climate by mitigating low temperature extremes and reducing erosion during rainfall. Establishment was similar between drip (subsurface and aboveground) and sprinkler‐irrigated treatments, but the use of protective covers is recommended when establishing turfgrass from seed.

Drip irrigation mode affects tomato yield by regulating root–soil–microbe interactions

A deep understanding of root–soil–microbe interactions in response to drip irrigation can help optimize drip irrigation techniques and improve crop yield; however, relevant knowledge remains limited. In this study, field experiments were conducted for two consecutive years to investigate the effects of surface drip irrigation (DI), subsurface drip irrigation (SDI), and alternate drip irrigation (ADI) on root–soil–microbe interactions and tomato yield. The results showed that the soil moisture distribution uniformity in the root zone (0–60 cm depth) was reduced in the order SDI > DI > ADI. In the SDI treatment, the tomato root lengths were 4.83- and 3.94-fold higher than those in the DI and ADI treatments, respectively, and the relative abundances of Patescibacteria in the bacterial community and Blastocladiomycota in the fungal community were significantly elevated. In the ADI treatment, the root length was 1.23-fold higher than that in the DI treatment, and the relative abundance of Patescibacteria also increased significantly compared with that in the DI treatment. These changes led to distinct root–soil–microbe interactions. The most intensive positive root–soil–microbe interactions occurred in the SDI treatment, followed by the ADI and DI treatments. The differences in the root–soil–microbe interactions regulated tomato yield. The tomato yield in the SDI treatment was increased by 19.77% and 7.77% compared with that in the DI and ADI treatments, respectively. In the ADI treatment, the tomato yield was 24.09% higher than that in the DI treatment. Therefore, the different drip irrigation methods can regulate tomato yield by affecting root–soil–microbe interactions. The results provide a reference for the optimization of the drip irrigation mode to regulate root–soil–microbe interactions and increase tomato yield.

PENERAPAN SISTEM MONITORING DAN KENDALI PINTAR UNTUK TANAMAN TERUNG BERBASIS INTERNET OF THINGS DENGAN METODE PENYIRAMAN IRIGASI TETES

Eggplant (Solanum melongena L.) is one of the horticultural crop products and vegetable crop commodities. Growth and quality are influenced by soil conditions, climate, and plant properties. The main source of agriculture is water and soil nutrients. This research applies a smart monitoring and control system for eggplant based on internet of things with the drip irrigation method. This system uses a NodeMCU V3 microcontroller as a controller for the aquatic and water pump. Besides using the Soil Moisture FC-28 sensor to measure soil moisture as an alternative to detect water availability in plants. DHT11 sensors are also given to monitor the temperature and humidity of the air around the plant. In the system there is a monitoring feature that can monitor air humidity, air temperature and soil moisture data. The system can automatically drip irrigation through the relay module when the soil moisture is below 50% and stop the watering process when it reaches 60% humidity. The sensor detection results can be monitored in the Blynk application and monitoring data, in the form of soil moisture, air temperature and air humidity, are saved to the database and can be downloaded in the format (.csv).

Effects of drip irrigation methods on yield and water productivity of maize in Northwest China

Water scarcity adversely affects the growth and yield of summer maize in the semi-arid region of Northwest China, and the application of irrigation technology to save water is an effective method for sustainable agricultural development in the area. In order to evaluate the potential of different drip methods for increasing grain yield and water productivity (WP), a 2-year (2018–19) field experiments was conducted to study the effects of various drip irrigation methods on the biomass accumulation and translocation and grain filling progress. The experiment involved three drip irrigation methods: conventional surface drip irrigation (CDI), subsurface drip irrigation (SDI) and alternate surface and subsurface drip irrigation in the soil vertical profile (ADI). The results showed that the ADI treatment had the highest above-ground accumulation of biomass at the maturity stage. However, no statistically significant differences were observed in all the treatments. The contribution of post-silking biomass to grain yield was ADI > SDI > CDI. Based on the two-year average analysis of data, the contribution of post-silking biomass to the grain yield in ADI was 3.6% and 7.0% higher than that in SDI and CDI, respectively. The maximum grain filling rate and the mean grain filling rate were the highest in the ADI, followed by SDI with CDI as the lowest. The active grain filling period and effective grain filling time were the highest under ADI and the lowest under CDI. There was a positive correlation between the active grain filling period and effective grain filling time. The ADI treatment decreased the grain number per spike but significantly increased the kernel weight. Two years of mean data demonstrated that the grain yield of the ADI was 6939.5 kg ha−1, which corresponded to increases of 4.8% and 13.3% from 6625.0 and 6126.5 kg ha−1 for SDI and CDI, respectively. For WP, the difference between treatments followed a similar pattern in 2018 and 2019, i.e., the ADI was significantly higher than the SDI, while the SDI was significantly higher than the CDI. Taken together, in addition to its potential for saving water, ADI has the additional advantage of promoting yield. Furthermore, the findings can contribute to a better understanding of the mechanism of biomass accumulation and grain filling process responses to drip irrigation methods.

The article explores the method of drip irrigation of agricultural crops, which provides a high coefficient of irrigation water (80–95%) and land (95%) use. This method helps to significantly save irrigation water by reducing losses for evaporation and filtration outside the root system zone, which eliminates surface runoff, unevenness of irrigation and creates the ability to maximize the use of irrigated areas for agricultural crops. The use of drip irrigation in vegetable production in the south of Kazakhstan since 2000 has radically changed the approach to the “water – soil – plant” complex. The authors believe that a metered feeding regimen would form a new approach to irrigation of agricultural crops, such as rice. Rice (Oryza sativa L.) as a food culture serves as one of the products consumed in food. It is grown in 120 countries on the area of more than 165 million hectares. Rice, unlike other agricultural crops, has a high biological plasticity and adaptive ability, which in modern agriculture allows it to be cultivated in a wide range of climatic conditions and irrigation methods, such as flooding, periodic irrigation and dry conditions. In world practice a continuous flooding of checks was the most widespread method of watering. This technology consumes about 50% of the total volume of irrigation water or 30% of the world’s fresh water reserves. The irrigation rate of rice cultivated with the use of this technology is in the range of 20–25 thousand m3/ha, which significantly exceeds the biological water consumption of rice agrocenosis. A significant part of the irrigation water is lost for filtration, discharges and lateral outflows. Currently, the use of drip irrigation method in rice fields is poorly studied. The research is aimed at substantiating the technology of rice cultivation using a low-pressure drip irrigation method in the conditions of Kyzylorda region

Determining the yield responses of maize plant under different irrigation scenarios with AquaCrop model

The AquaCrop simulation model is a significant implementation used to determine the response of crop yield to water and accordingly build up new strategies to improve agricultural irrigation management. Since determining the appropriate irrigation program in the field researches will require many years and labor; it becomes convenient with the AquaCrop to determine the adaptation of crops to the cultivating conditions and to examine the impact of possible variables such as drought on crop production.In this study, different irrigation scenarios were created, and yield predictions were made with the AquaCrop 6.1 model for maize plant which irrigated by drip irrigation method in Adana conditions, Turkey. These scenarios were created by determining four different depletion levels of readily available water (RAW) amount in the soil. These depletion levels were 25%(S1), 50%(S2), 75%(S3) and 100%(S4). The highest grain yield value was found in S1 as 10.075 ton/ha and the lowest grain yield in the S4 as 9.837 ton/ha. The amount of seasonal irrigation water simulated for different irrigation schedules varied between 348.5–390.7 mm, and the evapotranspiration (ET) varied between 411.5-426.5 mm. As a result, S3 scenario has been recommended considering the amount of irrigation water and the yields achieved.
