Irrigation Levels

The aim of this study is to determine the effect of four levels of irrigation water and three kinds of fertilizer on components of field-grown eggplant (Solanum melongena) in the years 2017 and 2018. Treatments included four irrigation regimes, which were 100% (I100, control), 80% (I80), 60% (I60), and 40% (I40) of evaporation from Class A pan and three different fertilizers, which were chemical fertilizer (CHF) with 40 kg da-1, organic fertilizer (OF) and developed organic fertilizer (DOF) with 2000 kg da-1. The experiment was designed with a split-plot randomized block with 3 replications. In experimental years, all irrigation treatments were irrigated 12 and 13 times, respectively with a drip irrigation system. Irrigation water amounts applied at I40, I60, I80, I100 in 2017 as 122, 183, 244, 305 mm and in 2018 were 147, 218, 289, 360 mm respectively. Seasonal plant water consumption values are in 2017, 2018 years respectively as follow: I40; 265 mm, 277 mm I60; 326 mm, 342 mm, I80; 386 mm; 382 mm, I100; 447 mm, 423 mm. In both experiment years, the effect of irrigation levels on plant components was statistically significant, the highest value of each component in both seasons was at I100 treatment, it was determined respectively as follow: Plant height PH (67.3 to 89.8 cm), branches number per plant BN (5.1 and 7.0), fruit number per plant FN (5.3 and 7.0), fruit weight FW (190.33 and 198.22 g).

The effect of irrigation and bio-stimulant (ComCat) applications on fruit quality parameters at the ‘Rubygem’ strawberry variety was investigated. The amounts of irrigation water applied were 0.50, 0.75, 1.00 and 1.25 times of water surface evaporation measured Class A pan placed over the crop canopy and the corresponding regimes were denoted as IR50, IR75, IR100 and IR125. Furthermore, bio-stimulant is applied four times with three weeks interval, approximately two months after planting. Applications of bio-stimulant were not efficient on examined parameters. Decreasing of the irrigation levels were significantly increased TSS and sugar/acid ratio which affects the fruit taste. The highest TSS and sugar/acid ratio was determined at IR50 plot with 9.42% and 21.7 values, respectively. However, fruit weight was significantly decreased except of IR100 plot. Moreover, deficient irrigation (IR50 and IR75) may cause a decrease at fruit weight. Recently, it could be crucial strategy to improve sugar and sugar/acid ratio which were prominent for consumers on the eating quality. Also, improving fruit taste with bio-stimulant application at optimum irrigation level (IR100) without any decreasing of fruit weight was determined.

Water use efficiency is a main research target in agriculture, which consumes 70% of global freshwater. This study aimed at identifying sustainable water management strategies for the lettuce crop in a semi-arid climate. Three independent experiments were carried out on a commercial variety of lettuce (Lactuca sativa L.) by applying different irrigation levels based on crop evapotranspiration (ETc), estimated through both the Hargreaves–Samani and Penman–Monteith equations. In the first experiment, one treatment was also guided by soil moisture sensors. In the second and third experiments, a factorial combination was used, combining the different irrigation levels with two soil mulching treatments, namely soil without mulch, and soil mulched with dried rice straw residues. The application of different irrigation levels significantly affected plant growth, yield, and physiology. Both the adoption of sensors for guiding irrigation and the application of mulching with straw promoted higher yield. As the irrigation water level was reduced, the WUE (water use efficiency) increased. WUE was also increased by covering the soil with mulch. The experiments point out that accurate management of irrigation water using a drip irrigation system associated with soil mulching increases yield and improves the WUE of lettuce crops in the Central Dry Zone, Myanmar.

This study aims to evaluate the Partial Root Zone Drying Irrigation System (PRD) as one of the modern technologies that provide irrigation water and increase the efficiency of its use on potato crop. The effect of applying the PRD conventional deficit irrigation (CDI) on the efficiency and water saving in potato crops using the drip surface (S) and subsurface (SS) irrigation methods were investigated. SALTMED model used to predict soil moisture and salinity distribution, soil nitrogen dynamics, and yield of potato crop using the different irrigation levels (150%, 100%, and 50% of Crop evapotranspiration (ETc)). The study showed that the water use efficiency (WUE) decreases with increasing levels of irrigation water, as it ranged between 2.96 and 8.38 kgm−3, 2.77 and 7.01 kgm−3 for surface irrigation PRD and CDI, respectively, when the amounts of irrigation water varied from 308 mm to 1174 mm, respectively. The study showed that the irrigation efficiencies were the highest when using PRD system in all treatments when irrigating the potato crop during the spring season, and it was more efficient in the case of using subsurface irrigation method. The results show that the soil moisture (SM) was high in 25–45 cm at 150% of ETc was 0.166 and 0.263 m3m−3 for the first and last stages of growth, respectively. 100% of ETc, (SM) was 0.296 m3m−3 at 0–25 cm, 0.195 m3m−3 at 25–45 cm, 0.179 m3m−3 at 45–62 cm, depths, respectively. whereas 50% of ETc, (SM) was 0.162 m3m−3 at 0–25 cm, 0.195 m3m−3 at 25–85 cm, depths. At 100% of ETc, soil salinity was 5.15, 4.37, 3.3, and 4.5 dSm−1, whereas at 50%, ETc, these values were 5.64, 9.6, 3.3, and 4.2 dSm−1. Statistical indicators showed that the model underestimated yield, for 150%, 100%, and 50% of ETc. Therefore, it can be concluded that yield and WUE using PRD systems were the highest in the potato crop compare to CDI surface and sub-surface, and SALTMED model can predict the moisture distribution, salinity, and yield of potatoes after accurate adjustment.

A three-year study was conducted on an Ultisol to determine the water requirement, yield and fruit-quality traits of three ratoon crops (R1, R2, R3) of ‘Grande Naine’ banana (Musa acuminata Colla, AAA group) subjected to four levels of irrigation. The irrigation treatments were based on Class A pan factors ranging from 0.0 (rainfed) to 1.0 in increments of 0.25. When needed, drip irrigation was supplied three times a week on alternate days. Results showed significant (p < 0.01) irrigation treatment and crop effects on bunch weight, yield, bunch mean hand weight, weight and fruit diameter of the third and last hands, and length of fruits of the third hand. Highest marketable yield (47.9 t ha−1) was obtained from the R2 crop with water application according to a pan factor of 1.0. It was concluded that irrigating the crop according to a pan factor of 1.0 was sufficient to justify the investment of a drip-irrigation system for a farm in the mountain region.

ABSTRACT Sunflower can be an economically viable crop in the Northeast region of Brazil depending on the use of appropriate irrigation and fertilization managements. The objective of this work was to evaluate production components of sunflower plants (Helianthus annuus L.) of the BRS-324 cultivar subjected to different organic fertilizer rates (goat manure) and irrigation water depths in two crop cycles (November 2014 to February 2015; and August to November 2015). The experiment was conducted in a randomized block design with a split-split-plot arrangement, consisting of five organic fertilizer rates (OFR) (0, 300, 600, 900, and 1.200 mL plant-1 week-1) and five irrigation water depths (IWD) (33; 66; 100; 133, and 166% of the class A tank evaporation), with three blocks. The highest achene yield (1,220.78 kg ha-1) in the first cycle was found using OFR of 1,200 mL plant-1 week-1 and IWD of 134.9% (524.9 mm); and the highest yield (882.07 kg ha-1) in the second crop cycle was found using the highest OFR combined with IWD of 166% (843.0 mm). The use of goat manure as organic fertilizer had no effect on the sunflower oil content; however, this variable was affected by the irrigation water depths used. Protein content was higher in the second crop cycle (14%) when using IWD of 100% and OFR of 536 mL plant-1 week-1.

The aim of this research was to study the effects of full and limited irrigation on the growing and productive characteristics of organically cultivated “Mountain Tea” (Sideritis raeseri). The research took place at the University of Thessaly farm in Velestino, Magnesia-Central Greece, during the year 2016, which was the second growing season. The experiment consisted of three treatments in three replications. Two of the treatments were irrigated: one treatment was irrigated with a supplied amount of water equal to the 75% of the daily water needs, while the other one was fully irrigated (100% of the daily water needs). Irrigation water was provided with a surface drip irrigation system. The third treatment was rainfed (no irrigation–0%). The results showed that limited irrigation compared to the full one, can save a significant amount of irrigation water while having the same results regarding the crop’s characteristics.

Verticillium wilt (VW) caused by Verticillium albo-atrum occurs in many irrigated alfalfa (Medicago sativa) fields in southwestern Saskatchewan, Canada, but is very rare in dryland stands. A trial was established in 1994 to determine if incidence of VW is affected by the amount of irrigation water applied. A line-source irrigation system was used to produce an irrigation water gradient on two adapted alfalfa cultivars, Beaver (VW-susceptible) and Barrier (VW-resistant). The irrigation gradient was subdivided into six irrigation level treatments within each cultivar plot. Irrigation plus precipitation from April to August averaged 265, 291, 309, 330, 351, and 353 mm for irrigation levels one to six, respectively, over 3 years. A 1-m-wide strip through the center of each subplot was inoculated with a spore suspension of V. alboatrum before the first harvest in 1995. Plant density (ground cover) and incidence of VW-diseased plants per subplot were recorded and forage yield was assessed twice per year. Beaver had more VW-infected plants in 1995 and 1996 than Barrier, and the number of diseased plants of Beaver increased with irrigation level. Ground cover of Beaver declined in 1997 and this response was correlated to VW-diseased plant counts from 1995 and 1996. There was no significant correlation between VW-diseased plant counts and ground cover for Barrier. Forage yield increased linearly with irrigation level for both cultivars in two harvests during 1995. However, yield of Beaver did not respond to irrigation during cut 2 in 1996. Beaver forage yield declined with irrigation level at cut 1 in 1997 because ground cover had declined by 40% at irrigation level six compared with 22% at irrigation level one. The ground cover of Beaver at irrigation level one was similar to that of Barrier at all irrigation levels. We conclude that VW will affect susceptible alfalfa cultivars on irrigated stands in proportion to the amount of irrigation water applied. Irrigated alfalfa producers should adopt VW-resistant cultivars even when irrigation is limited.

The increasing scarcity and competition for irrigation water entails adoption of innovative practices that increase efficient water use. The objective of this research was to compare different mulching techniques and investigated the combined effect of irrigation levels under drip irrigation system based on the parametric evaluation system in western part of Ethiopia during the 2018 dry season. A factorial combination of five levels of water (namely 100%, 80% and 70%, 60% and 50%ETc) combined with three mulch treatments (namely, Normal Mulch (NM), Straw Mulch (SM) and Plastic Mulch (PM)) with three replications. The analysis of variance showed that, days to 50% maturity, leaf number per plant, mean leaf length, plant height and leaf area were significantly affected by the main effects of deficit irrigation levels and mulching materials. The interaction effects of deficit irrigation levels and mulching materials significantly influenced plant height, number of leaf per plant, plant height, Leaf length and Leaf area of the onion. The present study suggests that, in water scarce area, farmers are advised to adopt deficit irrigation level with 80% ETc under plastic mulch. It is important even to undertake similar studies at different seasons with different varieties in consideration of their cost benefit analysis. However, if water is not a limiting factor, farmers are advised to apply full irrigation water application under plastic mulch.
