This study was carried out in order to determine the effects of the restriction of root zone on the growth and yield of tomato plant. In the study, on the date of 14.05.2015, "Perge" tomato variety were planted in a pot with a pot of 3 different sizes (S1: 11, S2: 16.5 and S3: 32 liters). The study was conducted in randomized in 3 replications according to a 3-factor trial design. Seedlings were planted in 15 pots including repetitions for each treatment. The research has been included in twelve treatments. 1-I1S1N1, 2-I1S2N1, 3-I1S3N1, 4-I2S1N1, 5-I2S2N1, 6-I2S3N1 7-I1S1N2, 8-I1S2N2, 9-I1S3N2, 10-I2S1N2, 11-I2S2N2, 12-I2S3N2 (I: irrigation levels; S: pot size, N: fertilizer application level). I1: Water application to all pots, taking into account the water decrease in the smallest pot, I2: Irrigation application according to water decrease considering the size of the pots; N1: Application of the amount of fertilizer applied for the smallest pot volume to all pots in both irrigation programs, N2: Treatments including fertilizer application considering the pot size were consisted. Irrigation water was applied by drip irrigation system and two different programs. In the first program, taking into account the water decrease in the smallest pot (11 liters), once water available in the soil before irrigation decreased to approximately 60% and equal amount of water was applied to all the pots until it reached the field capacity. In the second program, water was applied up to field capacity to each of the 16.5 and 32 liter pots, taking into account the existing water loss. The study was conducted in randomized in 3 replications according to a 3-factor trial design. In the study, root restraint applications achieved both high yields and significant savings from irrigation water. As a result, in similar conditions, it can be said that 11 liters of soil volume per plant will be sufficient and irrigation applied (I1S1) will be appropriate when the available water drops to about 60%.

The aim of this study is to compare the results of two different studies investigating the effects of different levels of irrigation on yield and quality of sugar beet (Beta vulgaris L.) and to propose a suitable irrigation program for sugar beet in Kırşehir conditions. These studies were carried out in a farmer's field in Çukurçayır in the center of Kırşehir in 2012 and 2013. Experiments were performed in randomized blocks split-plot design with three replications. In both experiments, irrigation scheduling utilized by using Class-A pan evaporation method within irrigation intervals. In the first study, treatments consisted of one irrigation interval (7 days); the two sugar beet varieties (C1: Esperanza and C2: Calixta) and three different irrigation levels (I1, I2, and I3) adjusted according to the Class-A pan evaporation using three different plant-pan coefficients (Kcp1: 0.5; Kcp2: 0.75; and Kcp3:1.00). In the second study; treatments consisted one sugar beet variety (C1:Isella ) four nitrogen fertilizer levels (N1: 30kg ha−1; N2: 40 kg ha−1; N3: 50kg ha−1; and N4: 60 kg ha−1) based on the same irrigation program. In the first study, the lowest and the highest values of irrigation water and plant water consumption (Et) were observed in the I1 and I3 treatments in both years, respectively. In 2012, the lowest and the highest root yields were observed in the I3C1 (85.38 t ha−1) and I2C2 (75.10 t ha−1) treatments. In the second experimental year, the lowest and the highest root yields were achieved with the I3C1 (66.13 t ha−1) and I1C2 (47.57 t ha−1) treatments, respectively. The impact on the examined parameters of irrigation programs in the C2 treatment had not significant. On the other hand, in the C1 treatment of irrigation programs had a significant effect on sugar rate, sugar yield, and other parameters. If the economic yield and quality are desired, the I1C1 treatment can be suggested for sugar beet production under the similar soil and climatic conditions. In the second study; the highest WUE and IWUE values, the best quality parameters (Na, K, and alpha-amino nitrogen), and economic sugar beet root yield was determined in the treatment of I1N1 (Kcp1: 0.5 and 30 kg ha−1 of N). When both study results are examined, it can be said that Kcp1: 0.5 plant-pan coefficient in sugar beet irrigation program is most important for economic yieldy and quality. [ABSTRACT FROM AUTHOR]

The present study was conducted to determine the effect of different irrigation and nitrogen levels on yield, yield components, and sugar rate of the sugar beet ( Beta vulgaris L.) during the years 2012 and 2013 in the Kırşehir province of Turkey. Experiments were carried out in split plots in randomized blocks with three replications. The application of irrigation water was based on cumulative class A pan evaporation within the irrigation intervals. Treatments consisted of one irrigation interval (7 days) and three different irrigation levels (I 1 , I 2 , and I 3 ) adjusted according to the class A pan evaporation (E pan ) using three different plant-pan coefficients ( K cp1 : 0.5; K cp2 : 0.75; and K cp3 : 1.00) and four nitrogen fertilizer levels (N 1 : 30 kg ha −1 ; N 2 : 40 kg ha −1 ; N 3 : 50 kg ha −1 ; and N 4 : 60 kg ha −1 ). The highest WUE and IWUE values, the best quality parameters (Na, K, and alpha-amino nitrogen), and economic sugar beet root yield was determined in the treatment of I 1 N 1 ( K cp1 : 0.5 and 30 kg ha −1 of N). Therefore, this treatment can be used for sugar beet cultivation under similar climate and soil conditions. [ABSTRACT FROM AUTHOR]

This study examines the effects of different irrigation regimes on water use and root yield of sugar beet, irrigated with a drip system under field conditions in the 2012–2013 seasons at Cukurcayir in the Kırsehir Centrum of the Central Anatolian region of Turkey. Experiments were carried out in split plots in randomized blocks with three replications. The application of irrigation water was based on cumulative class A pan evaporation within irrigation intervals. Study treatments consisted of one irrigation interval (7 days); the two sugar beet varieties (C 1 : Esperanza and C 2 : Calixta) and three different irrigation levels (I 1 , I 2 , and I 3 ) adjusted according to the class A pan evaporation ( E pan ) using three different plant-pan coefficients ( K cp1 : 0.5; K cp2 : 0.75; and K cp3 : 1.00). The lowest and the highest values of irrigation water and plant water consumption ( Et ) were observed in the I 1 and I 3 treatments in both years, respectively. In 2012, the lowest and the highest root yields were observed in the I 3 C 1 (85.38 t ha −1 ) and I 2 C 2 (75.10 t ha −1 ) treatments. In the second experimental year, the lowest and the highest root yields were achieved with the I 3 C 1 (66.13 t ha −1 ) and I 1 C 2 (47.57 t ha −1 ) treatments, respectively. The impact on the examined parameters of irrigation programs in the C 2 treatment had not significant. On the other hand, in the C 1 treatment of irrigation programs had a significant effect on sugar rate, sugar yield, and other parameters. If the economic yield and quality are desired, the I 1 C 1 treatment can be suggested for sugar beet production under the similar soil and climatic conditions. [ABSTRACT FROM AUTHOR]

Abstract: This study was conducted to determine the most suitable plant-pan coefficient for eggplant, using pan evaporation values, in field conditions. Application of irrigation water was based on cumulative class A pan evaporation within the irrigation intervals. Irrigation treatments consisted of one irrigation interval (I1: 7 day) and five plant-pan coefficients (K cp1: based on percent crop canopy closure; K cp2: 0.50; K cp3: 0.70; K cp4: 0.90; K cp5: 1.10). Average irrigation values for each treatment varied from 372 to 689mm, average evapotranspiration values ranged from 420 to 689mm and eggplant fruit yield ranged from 10.11 to 21.14tonnesha−1. The highest total and early fruit yield was obtained from the K cp4 and K cp3 treatments, respectively. Seasonal yield response factor (K y) was 0.60. E t/E pan ratios for each treatment varied from 0.18 to 1.32. In addition, irrigation levels substantially affected yield (P <0.001) and fruit number (P <0.01). A significant correlation between irrigation water volume and plant vegetative growth traits, and between plant water consumption and fruit yield, were found. Thus, in irrigation programming, the K cp4 plant-pan coefficient is recommended for field-grown eggplant. [Copyright &y& Elsevier]
