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.

The genus Heliconia is commercially detached by the exotic appearance of the inflorescences but is susceptible to lack of moisture in the soil, being necessary the irrigation management. In this sense, the objective was to evaluate the effect of different irrigation levels on the plant growth and productive characters of Heliconia psittacorum cv. Golden Torch cultivated in vase. The experiment was conducted from March to October 2014, in a randomized blocks design. Five treatments corresponding to the different irrigation levels were used [50, 75, 100, 125 and 150% of the evaporation measured in Class A (ECA)] with four replicates and two plants per replicate. The following evaluations were carried out: number of days for the emergence of the first tiller, number of days for the emergence of the first inflorescence, number of days for the inflorescence harvest, crop cycle, diameter of the flower stem, length of the flower stem, inflorescence length, plant high, number of tillers and productivity of flower stems. Chlorophyll and leaf area measurements were performed. The irrigation levels tested significantly influenced the number of days for the first inflorescence harvest, length of the flower stem and inflorescence length. The irrigation level of 150% ECA provided better results for the length of the flower stem, inflorescence length and for leaf area but without differences from 75%, 100% and 125% ECA. Thus, for the cultivation of the heliconia cv. Golden Torch in pot can be recommended the level corresponding from 75% to 150% ECA.

Abstract The objective of this study was to assess the effect of planting densities, irrigation levels and bunch trimming on yield, fruit grading and water-use efficiency (WUE) of ‘Prata-Anã’ banana plants. The following factors were combined in a randomized block design: three irrigation levels (IL), 50, 75 and 100% crop evapotranspiration (ETc); four planting densities (PD)- 1,666; 2,083; 2,666 and 3,333 plants ha-1; and two bunch trimming treatments (BT), removal of either one or two hands from the bunch. The treatments were arranged in a split-split plot design. Irrigation level was assigned to main plots, PD to subplots and BT to sub-subplots, with four replicates. Measurements were made in the first production cycle. Removing two hands increased number of leaves, leaf area, leaf area index, fruit weight, fruit diameter, total hand weight and mean hand weight of ‘Prata-Anã’ banana plants. A plant density population of 3,333 plants ha-1 combined with an irrigation level at 75% ETc improves plant development and yield while maintaining fruit size and saving water, regardless of removal of one or two hands from the bunch.

The interaction between irrigation and crop load with respect to fruit size distribution was investigated in a `Golden Delicious' apple (Malus domestica Borkh) orchard located in a semi-arid zone. Irrigation levels during the main fruit expansion phase ranged from 0.42 to 1.06 of the Class A pan evaporation coefficient. Crop load was adjusted to 100 to 450 fruit/tree in the 1250 trees/ha orchard by hand thinning. Total yield was not affected by irrigation level up to a crop load of 200 fruit/tree. Yield of all grades >65 mm was affected by irrigation level for higher crop densities. The yield of fruit of diameter <75 mm was not affected by increasing the Class A pan evaporation coefficient above 0.75. Our data indicate that availability of assimilates may limit the size of fruit with potential to grow larger than 70 mm in diameter at all crop loads higher than 200 fruit/tree. This limitation increases with decreasing irrigation level. The volumetric relative growth rate (VRGR) increased with irrigation level and with decreasing crop load. VRGR was more affected by crop load than by irrigation level in the ranges studied.

O plantio da área foi realizado com mudas de coqueiro anão denominado Verde de Jiqui, espaçadas em 7,5 x7,5 m,em triângulo. Odelineamento experimental empregado foi o de blocos ao acaso, com três tratamentos, quatro repetições e oito plantas por parcela, porém, para eliminar o efeito ano, os dados foram analisados como parcelas subdivididas. Os tratamentos consistiram na aplicação da irrigação quando a evaporação acumulada de um tanque Classe “A” atingiu 10, 30 e50 mm, tratamentos T1, T2 e T3, respectivamente. A massa média dos frutos nos anos estudados foi de2.226 g, sendo que os tratamentos não apresentaram diferenças significativas. A média do diâmetro polar foi de55,16 cme do diâmetro equatorial foi de50,01 cm, o que demonstra ser o fruto bastante arredondado. Quanto ao volume de água, os tratamentos T1, T2 e T3 apresentaram médias semelhantes nos dois anos estudados e iguais a0,486 L. O teor médio de sólidos solúveis da água de coco, durante os dois anos de produção, foi de 5,77 ºBrix, e a média dos tratamentos não apresentaram diferenças estatísticas. Os resultados encontrados demonstraram que a freqüência de irrigação a cada cinco dias foi a mais adequada em termos de redução de custos de produção e aumento da renda. UNITERMOS: manejo da irrigação, tanque Classe “A”, irrigação localizada.                                                        AZEVEDO, B.

EFFECT OF IRRIGATION FREQUENCY IN THE FRUIT QUALITY OF THE DWARF COCONUT TREE  2 ABSTRACT             This work was carried out in Paraipaba, CE,Brazil, and aimed to evaluate, during two years, the development and production of the dwarf coconut trees, when submitted to different irrigation frequencies. “Verde de Jiqui” dwarf coconut seedlings were planted in a area with 7.5 x 7.5m spacing in a triangular arrangement. The experimental design had randomized blocks, three treatments, four replications and eight plants per plot. However, in order to eliminate the effect of the year, data were analyzed in split plots. The treatments consisted of irrigation when accumulated evaporation of a Class “A” pan reached 10, 30 and50 mm, for the treatments T1, T2 and T3, respectively. The average fruit weight in the studied years was2.226 g, and the treatments did not present significant differences. The polar diamete averager was55.16 cmand the equatorial diameter one was 50.01 cm; that demonstrates the fruits were quite round. In relation to water volume, treatments T1, T2 and T3 presented similar averages in the two studied years:0.486 L. The average soluble solids content in the coconut water during the two- year production was 5.77 ºBrix, and the treatment average did not present statistical differences. Obtained results showed that frequency irrigation with 5-day intervals was the most appropriate one for production cost reduction and income increase. KEYWORDS: irrigation management, Class “A” pan, trickle irrigation

Crop Geometry

An experiment was conducted to study the effect of crop geometry and irrigation levels on sugarcane under drip irrigation at Main Sugarcane Research Station, Junagadh Agricultural University, Kodinar during 2011-14. The treatment consisted of three crop geometry (90 cm normal planting, paired row planting (60: 90 cm) and paired row planting (60: 120 cm) and three drip irrigation levels (0.5 PEF, 0.7 PEF and 0.9 PEF) and with an extra treatment (control) having surface irrigation (90 cm) at 1.0 IW/CPE ratio. Experimental results indicated that paired row (60: 90 cm) planting gave significantly higher cane yield (101.04 t/ha) over 60: 120 cm paired row planting (88.82 t/ha) and remained at par with 90 cm row spacing (97.34 t/ha). Drip irrigation level of 0.9 PEF gave significantly higher cane yield (108.63 t/ha) over 0.7 PEF (96.01 t/ha) and 0.5 PEF (82.56 t/ha). Juice quality parameters like brix, sucrose, purity and sugar recovery percent were not affected significantly due to either crop geometry or different drip irrigation levels. Significantly higher cane yield was recorded under drip irrigation (95.74 t/ha) compared to surface irrigation (76.86 t/ha). The total water use was not affected due to different crop geometries. Water use decreased constantly in 0.7 and 0.5 PEF compared to 0.9 PEF and accordingly WUE increased.

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).

Oil content and fatty acid composition are the most significant quality criteria of peanuts (Arachis hypogaea L.), and these parameters is greatly influenced by irrigation and fertilization practices. A study was conducted to investigate the effects of irrigation intervals and irrigation levels on oil content and fatty acid composition of peanuts, under sandy soil conditions in two consecutive years, using ‘Halisbey’, ‘NC-7’, and ‘Sultan’ peanut cultivars, commonly grown in Turkey. Irrigation levels were arranged based on total evaporation from Class-A pan, and irrigations were applied through drip lines. Irrigation intervals were set as two and four days, and irrigation levels were set as 50% (I50), 75% (I75), 100% (I100) and 125% (I125) of Class-A pan evaporations. Oil content, unsaturated fatty acids (oleic and linoleic acids), and saturated fatty acids (palmitic, myristic, arachidic, behenic and lignoceric acids) were determined. For oil content, treatments were identified as the most appropriate irrigation for a two-day irrigation interval of all cultivars, I100 for four-day irrigation interval of ‘Halisbey’ and ‘Sultan’ cultivars and I75 for four-day irrigation interval of ‘NC-7’ cultivar. Oleic, linoleic, and palmitic acids were the major fatty acids of peanuts. Cultivars exhibited different variations in these fatty acids based on irrigation intervals and irrigation levels. In general, oleic acid contents decreased, but linoleic and palmitic acid contents increased with increasing irrigation levels. The greatest oleic acid contents were obtained from two and four-day irrigation intervals of I50 treatments in ‘Halisbey’ and ‘NC-7’ cultivars and from two and four-day irrigation intervals of I75 treatments of the second year in ‘Sultan’ cultivar. Present findings revealed that for quality peanut production, both irrigation intervals and irrigation levels should be taken into consideration.

There is a scarcity of information regarding the optimum water requirement for papaya (Carica papaya) grown under semiarid conditions with drip irrigation in the tropics. A two-year study was conducted to determine water requirement, yield, and fruit quality traits of papaya cv Red Lady subjected to five levels of irrigation. The irrigation treatments were based on Class A pan factors that ranged from 0.25 to 1.25 in increments of 0.25. Drip irrigation was supplied three times a week on alternate days. Results showed significant effects of irrigation on number of fruits, yield and fruit length. Irrigation treatments did not have a significant effect on brix (sweetness). Highest marketable fruit weight (75,907 kg/ha) was obtained from plants irrigated according to a pan factor of 1.25. It was concluded that papaya grown under semiarid conditions should be irrigated according to a pan factor of not less than 1.25.

Greenhouse Tomato

The impact of water quality with varying deficit irrigation level on the plant biomass and fruit quality parameters of greenhouse tomato (Lycopersicon esculentum L. cv Izmir) was investigated. A pot-based experiment was carried out over two growing seasons (2017-2018 and 2018-2019). Three water qualities: groundwater, recycled wastewater and an equal mix of both were applied in four irrigation scenarios which aimed to maintain soil moisture levels at 60%, 70%, 80% and 100% of field capacity. A surface drip irrigation system was designed maintaining irrigation frequency of two days. Results showed that both water quality and deficit irrigation significantly affected plant biomass. The fresh fruit weight was rather uniform, ranged from 53.2 to 85.4 gram and found highest in full irrigation. Most of the fruit quality parameters were not significantly affected by water quality.The significantly higher values of total soluble solid (7.87 degree brix), fruit firmness (9.28 kg/cm2), fruit pH (4.24) and vitamin C content (68.33 mg/kg) were measured in treatments maintaining soil moisture content at 60% of field capacity (most water-stressed conditions). Based on these findings, it recommended that by adopting deficit irrigation and maintaining soil moisture at 60% of field capacity, fruit quality parameters can be significantly improved. In contrast, fresh fruit weight and plant biomass were reduced.

Abstract In this study, yield and water productivity response of rice to various irrigation levels applied with subsurface and surface drip systems in 2019 and 2020 in the Mediterranean Region of Turkey was evaluated in comparison with conventional flooding (CF). The treatments consisted of two irrigation methods namely surface drip (DI) and subsurface drip systems (SDI), three irrigation levels designated as plant pan coefficients (I1.00: Evaporation from Class A pan (Ep) × 1.00; I1.25: Ep × 1.25 and I1.50: Ep × 1.50) and CF as control. The effects of drip systems and coefficients on yield and yield components were statistically significant (P < 0.01). DI produced higher yield than SDI. CF produced significantly greater yield than both DI and SDI systems. With two drip systems, average water savings of 60.5% in I1.00, 54.5% in I1.25 and 49% in I1.50 were achieved as compared to CF. However, yield reductions of 15% in I1.50, 20% in I1.25, 29% in I1.00 were observed for DI; corresponding values for SDI were 20, 28 and 44%, respectively. Drip irrigation in aerobic rice production system had almost twice the water productivity based on total irrigation water applied (WPI) or total water input (irrigation + rainfall) (WPI+P) compared with CF. During the study years, the highest WPI and WPI+P values were found in DI-I1.00 (0.81–0.73 kg/m3) and (0.85 and 0.74 kg/m3), respectively. In conclusion, DI-I1.50 treatment is recommended for sustainable aerobic rice production since DI-I1.50 resulted in water saving of 49% but yield decrease of 15% as compared to CF.
