Vegetative Growth and Yield of Tomato as Affected by Water Regime and Mulching
2013
An experiment was carried out with potted tomato plants to investigate the interactive effect of water regime and mulching on the growth and yield of tomato; conducted during the 2012/2013 dry season at the Federal College of Forestry Jos, Nigeria to evaluate water management options on the performance of tomato. The experiment consisted of three levels of irrigation water application depths (0.3, 0.4 and 0.5 liter/day/plant) and three types of mulch materials (Black polyethylene, white polyethylene and straw were used to cover the soil surface of the pots). The pots were arranged in Randomize Complete Block Design (RCBD) system. Watering with different volume of water was done throughout the growth period, the result showed that water regime has no significant effect on vine length, leaf number, leaf area, stem girth but at plant yield except at 4WAT, while the effect of mulch on Vine length and stem girth were significant but leaf number, leaf area, stem girt were not significant....
The effects of deficit irrigation and mulching practices to crop yield and crop water use (CWU) of tomato crop were examined at Kano River Irrigation Project (KRIP), during 2014 dry season irrigation farming. The experiments comprised of four levels of water application depths (40, 60, 80, and 100% of weekly reference evapotranspiration) and four levels of mulching; No-Mulch (NM), rice-straw-mulch (RSM), wood-shaving-mulch (WSM) and white-polyethylenemulch (WPM). The total mean yield ranged from 6.98 to 23.67 t/ha with an annual average of 11.48, 18.48, 11.98 and13.33 t/ ha for NM, RSM, WSM and WPM treatments respectively. The seasonal applied water (SAW) ranged from 362.92 to 907.28 mm while the seasonal crop water use (SCWU) was found to be between 250.73 and 782.60 mm. The results of SCWU of fully irrigated treatment were NM (782 mm), RSM (725 mm), WSM (692.83 mm) and WPM (629 mm). The least value in the range was obtained in the I40 (60% deficit) treatments with WPM, while the highest value in the range was recorded in the I100 treatment with NM. The analysis of variance shows that SCWU was largely influenced by both the water application depth and mulching and it further revealed that the effect of various levels of irrigation and mulching practices on yield were found to be highly significant (**) at 5% level of significance with high mean yield value of 15.84t/ha and 18.48t/ha and also with mean CWU value of 675.40mm and 556.60mm obtained at I80 and RSM. This implies that both deficit-irrigation and mulching practices of tomato crop has significant effect on yield and CWU of tomato grown in the study area. However, it was analytically concluded that the best level of irrigating tomato crop at the site is at I80 giving mean yield of 15.84 t/ha at mean crop water use of 675.40 mm/season and
Effect of mulching and amount of water on the yield of tomato under drip irrigation
Journal of Horticulture and Forestry, 2011
The main challenge confronting both rain fed and irrigated agriculture is to improve WUE and sustainable water use for agriculture. An experiment was conducted to evaluate the effect of mulch and amount of water on the yield of tomato under drip irrigation system and to assess the potential of deficit irrigation to improve the economic efficiency of tomato production at Adet Agricultural Research Center, horticultural crops trial site (Woramit) (North Western Ethiopia) from 2006 to 2007. A factorial combination of three levels of water (namely 315, 440 and 565 mm) combined with three mulch treatments [namely without mulch (WM), black plastic mulch (PM) and straw or crop residue mulch (STM)] amid three replications andtwo days irrigation interval was used. Amount of water significantly affected the number of fruits per plant, average weight of fruits marketable and total fruit yield/ha. Significant difference was also shown between mulch treatments on number of fruits, unmarketable, ...

Irrigation management strategy invites the quantification of crop response to irrigation frequencies. Conventionally, mulches increase the yield and water use efficiency (WUE) to a great extent by augmenting the water status in the root zone profile. A field study was carried out during the winter season (November-March) of 2003-2004 and 2004-2005 at the Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya (Latitude 22 • 58 N, Longitude 88 • 31 E and altitude 9.75 m amsl), Gayeshpur, India, to evaluate the effect of irrigation frequencies and mulches on evapotranspiration rate from tomato crop field as well as leaf area index (LAI), fruit yield and WUE of the crop. The experiment was laid out in a split-plot design where three irrigation treatments {rainfed (RF); CPE 50 and CPE 25 where irrigation was given at 50 and 25 mm of cumulative pan evaporation (CPE)} were kept in the main plots and the subplots contained four mulch managements {no mulch (NM), rice straw mulch (RSM), white polyethylene mulch (WPM) and black polyethylene mulch (BPM)}. Under CPE 25 , tomato crop recorded significantly higher leaf area index (LAI) over CPE 50 and rainfed condition. LAI value under BPM was 9-30% more over other mulches. Maximum variation of LAI among different treatments was recorded at 60 days after transplanting (DAT). Fruit yield under CPE 25 was 39.4 Mg ha −1 ; a reduction of 7 and 30% has been obtained under CPE 50 and RF condition. The use of mulch increased 23-57% yield in comparison to NM condition. Actual evapotranspiration rate (ET R) was 1.82 mm day −1 under CPE 25 and declined by 15 and 31% under CPE 50 and RF condition, respectively. The variation of ET R among different mulches became more prominent under maximum water stressed (RF) condition, whereas the variation was negligible under CPE 25 frequency. Irrespective of mulching WUE was highest under moderately wet (CPE 50) soil environment. Among different mulches, BPM was responsible for attaining the highest WUE value (25.1 kg m −3), which declined by 22, 21 and 39% under WPM, RSM and NM, respectively.
Effect of Different Mulching Materials on Yield and Growth Parameters of Tomato Crop
Current Journal of Applied Science and Technology, 2021
The present investigation was carried out to study the performance of yield and growth parameters of tomato crop under different mulching materials. This experiment was conducted at Vikas College of Engineering and Technology, Nunna, Vijayawada during the period from Jan 2020 to April 2020. The experimental field has an area of 180 m2 (15m × 12m) and divided into 4 plots i.e., Drip with plastic mulch (A), Drip with live mulch (coconut coir) (S), Drip without mulch (M) and Control (without mulch and without drip) (K). Growth parameters like plant height, number of leaves per plant, soil parameters like bulk density, soil temperature, soil moisture and yield were observed for each treatment. Crop water requirement was calculated using CROPWAT 8.0. The results showed that the bulk density has no effect between the treatment plots. The soil moisture in initial stage is more in K and least in S; in flowering stage, M was high and least in K and in harvesting stage, it is high in A. The s...

During the winter season (November-March) of 2003-2004 and 2004-2005 a field study was carried out at the Research Farm of the University (Latitude 22 • 58 N, Longitude 88 • 31 E and altitude 9.75 m amsl), Gayeshpur, India. Aim of the study was to evaluate the sole and interactive effect of irrigation frequencies and mulches on performance and water productivity functions of tomato crop. The experiment was composed of three irrigation frequencies {rainfed (RF); CPE 50 and CPE 25 where irrigation was given at 50 and 25 mm of cumulative pan evaporation (CPE)}, kept in the main plots. The subplots consisted of four mulch managements {no mulch (NM), rice straw mulch (RSM), white polyethylene mulch (WPM) and black polyethylene mulch (BPM)}. Fruit yield under CPE 25 was 39.4 Mg ha −1 ; it reduced by 7 and 30% respectively under CPE 50 and RF condition. Different mulches increased fruit yield by 23-57% over non-mulch condition. Irrespective of mulching, water use efficiency (WUE), net evapotranspiration use efficiency (WUE ET) and irrigation use efficiency (WUE I) were found to be the highest (22 kg m −3 , 71 kg m −3 and 22 kg m −3 respectively) under moderately wet (CPE 50) soil environment. Among different mulches, BPM recorded the highest WUE (25 kg m −3), WUE ET (73 kg m −3) and WUE I (26 kg m −3) values. Critical values of seasonal evapotranspiration (SET) against maximum WUE and maximum yield were computed through marginal analysis of water productivity function. It was observed that the difference between these critical values was narrowed down under bio or polyethylene mulches compared to the bare situation.
Yield in tomato under two water depths and plastic mulching
Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2019
The search for sustainable agriculture is a reality that aims saving water and agricultural inputs to obtain greater productivity. Some techniques can be used for this purpose, such as drip irrigation and the plastic mulch of the soil. Thus, the aim of this study was to verify the effects of plastic mulch under two water depths on the productive characteristics of a commercial tomato field. The employed experimental design was the completely randomized in a 2 x 2 factorial. The sources of variation were two types of soil cover (with and without plastic mulch) and two water depths (164 mm and 188 mm) with nine replicates. Plant height and water use efficiency were not influenced by soil mulch or water depth variation. Soil with plastic mulch provided a lower mean fruit mass (108.32 g fruit-1), however, with a higher number of fruits per plant (70), which contributed to a higher commercial yield (58.42 t ha-1). The highest total yield (64.08 t ha-1) was obtained in the soil with plastic mulch under the water depth of 188 mm. The use of plastic mulch associated with a water depth of 188 mm provided an increase in tomato yield.

In areas where the supply of water for irrigation is limited, tomato production is often subject to drought stress. This study was conducted at the Department of Horticulture and Landscape Gardening, University of Diyala, Baqubah, Iraq in 2021 wherein 22 genotypes ('S.G', 'San II', 'M.O', 'Red Pear', 'F.R', 'Marb', 15 F1 hybrids were obtained from 6×6 half diallel cross and 'Bobcat' control hybrid) were cultivated under full irrigation [covering 100% of crop evapotranspiration demands (ETc)] and water deficit (50% of ETc) conditions. The results showed that cv. 1×6 produced the longest plants (119.01 cm) and the least time to flowering (10.23 days). Most branches (31.98) were produced by cv. 5×6. Both cvs. 1×6 and 5×6 produced the most leaf area (1 991 and 1 977 cm 2 respectively) and most yield per plant (6.75 and 6.84 kg respectively). The 100% ETc irrigation treatment produced the longest plants (91.21 cm), the greatest number of branches (28.12), the most leaf area (1 673 cm 2), and the highest plant yield (4.61 kg). The 50% ETc irrigation treatment produced the least time to flowering (13.7 days). Irrigation level lowering to 50% ETc achieved good results for the water use efficiency (WUE) use with predicted R 2 = 1.00. Therefore, the results of this study recommend using the interaction of (both cvs. 1×6 and 5×6 irrigated with the 50% ETc treatment) to save water on irrigation and produce a high yield of tomatoes.
