Stress Influence

Tomato, also known as Solanum lycopersicum, is one of the horticultural commodities that have a good priority to be developed. Tomato production in Indonesia has decreased over five decades. This lack of production is caused by the limitation of water supply during the dry season as to effect of its rooting. One of the ways of ensuring water supply is using an irrigation system, including drip irrigation. The use of drip irrigation will save a lot of water, but the allocation of water to be given will cause to salinity. This phenomenon requires actions to control the water for tomato production. Research in this area is being carried out in the subdistrict of Lubuk Kilangan, Padang City. The current study observes the effect of salinity on the amount of leaf, the productivity, and the sweetness of the tomato fruit. Based on the results, the efficiency of drip irrigation is around 96.28%, and there is no real effect of salinity on the amount of leaf. Additionally, salinity does not affect productivity. The highest productivity is on the treatment of giving water at -15%, amounting to 2.30 kg, and the lowest is at -5%, amounting to 1.72%. Salinity increases the sweetness of tomato, and the highest sweetness level is on the treatment of giving water at -20%, amounting to 5.6600 Brix, and the lowest sweetness level is at the control treatment, amounting to 5.1100 Brix.

A field experiment was carried out in the field of the College of Agriculture / University of Wasit, located on longitude  45o   50o   33.5o   East and latitude 32o 29o 49.8o North, in Spring season of the agricultural season 2019, in order to estimate the water consumption of potato crop using SWRT technology and under the drip irrigation system. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replications and four treatments that include of the SWRT treatment (the use of plastic films under the plant root area in an engineering style), and the treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and the control treatment . Potato tubers (Solanum tuberosum L.)  var. Burin was planted for spring season on 10/2/2019 at the soil depth of 5-10 cm. The highest reference water consumption for the potato crop during the season was calculated by Najeeb Kharufa, which was 663.03 mm. The highest actual water consumption for the potato crop during the season for the control treatment was 410.1 mm. The results showed increase in the values of the crop coefficient (Kc) in the stages of tubers formation and tubers filling stage as compared to the vegetative and ripening stages, ranged from 1.37-1.92 for the two stages of tubers formation and tubers filling. The SWRT treatment gave the highest water use efficiency during the season, was 3.46 kg m-3 .

On sandy soils, potential N contamination of groundwater resources associated with intensively managed vegetables may hamper the sustainability of these systems. The objective of this study was to evaluate the interaction between irrigation system design/scheduling and N fertilization rates on zucchini production and potential N leaching. Zucchini was planted during Fall 2005 using three N fertilizer rates (73, 145, 217 kg/ha) and four different irrigation approaches. Irrigation scheduling included surface-applied drip irrigation and fertigation: SUR1 (141 mm applied) and SUR2 (266 mm) using irrigation control system (QIC) that allowed time-based irrigation (up to five events per day) and a threshold setting of 13% and 15% volumetric water content (VWC), respectively; Subsurface drip irrigation (SDI) using a QIC setting of 10% VWC (116 mm) combined with surface applied fertigation; and a control treatment with irrigation applied once daily (424 mm). Leacheate volumes were measured by drainage lysimeters. Nitrate leaching increased with irrigation rate and N rate and measured values ranged from 4 to 42 kg N/ha. Use of SDI greatly reduced nitrate leaching compared to other treatments. SDI and SUR1 treatments had no effect on yields (29 Mg/ha). However, SDI had a 15% and 479% higher water use efficiency (WUE) compared to SUR1 and the fixed irrigation duration treatment. Application of N in excess of intermediate N-rate (standard recommendation) did not increase yield but yield was reduced at the lowest N-rate. It is concluded that combining sensor-based SDI with surface applied fertigation resulted similar or higher yields while it reduced both water use and potential N leaching because of improved nutrient retention in the active root zone.

In this study, we developed an automatic irrigation method using an image-based irrigation system for high-quality tomato production in a greenhouse by investigating effects of a diurnal periodic cycle of irrigation on the photosynthesis, growth, yield, and fruit quality of tomatoes. The diurnal periodic cycle in a moderate wilting–full recovery treatment (MR) with a medium threshold value was more frequent than that in a severe wilting–full recovery treatment (SR) with a high threshold value. Mean daily maximum wilting ratios for MR and SR were 7.2% and 11.3%, respectively, when wilting ratios were set to threshold values of 7% and 14%, respectively. Total irrigation amounts in MR and SR were similar and lower than that in the untreated control. Net photosynthetic rate decreased under water stress, with values in MR being higher than that in SR, and recovered rapidly to more than 90% of its maximum value following irrigation. Plant growth and fruit yield per plant in MR and SR were lower than that in the control. Water stress treatment could improve fruit quality when it commenced at the anthesis stage or early fruit development stage. Total irrigation amount was a more important parameter than the threshold value for controlling the growth, yield, and fruit quality of tomatoes.

Impact On Biodiversity

Tomato (Solanum lycopersicum) is one of the most important vegetable crop whose production involves the use of synthetic herbicides with detrimental impact on biodiversity. Allelopathy effectively controls horticultural crop weeds. Different plant parts (flowers, leaves, stems, bark, roots) have allelopathic activity that varies over a growing season when used as mulch.  Mulching is a horticultural technique that protects the roots of plants from heat and cold by use of mulch to cover the soil surface around plants. Tomato production in Kakamega County is below 2% and weeds are ranked high among the yield reducing factors. This study assessed the allelopathic effect of guava leaves mulch type (18.0 cm thick) as a management tool for weed control in tomato crops and no mulch as control treatment with three most popular determinate tomato varieties. The mulch treatments were arranged as factorial in a Randomized Complete Block Design (RCBD) to minimize non–experimental bias. Tomato variety sub-treatments were replicated three times in the experimental plots at Masinde Muliro University of Science and Technology (00171N, 340451E). The field project was conducted during the short rains and long rains season of 2016-2017. Data obtained was subjected to analysis of variance (ANOVA) using SAS software, version 9.3 at p<0.05 confidence level. Least Significance Difference (LSD) was used to separate the means. Weed density incidence was significantly highest in control plots up to 100% and lowest in mulched plots (13.41%). Allelopathic control of weeds sustains global food and nutrition security for future generations.

Three vegetable irrigation systems, semi-closed subirrigation (seepage), fully enclosed subirrigation (seepage), and drip irrigation, were evaluated for use on sandy soils with naturally high water tables to determine comparative irrigation costs for tomato production. Investment, fixed (ownership), and variable (operating) costs were estimated for each irrigation system. The investment costs of the drip irrigation system were significantly greater than those for the semi-closed and fully enclosed irrigation systems. The variable costs, however, for the semi-closed system were considerably less than those for the fully enclosed and drip irrigation systems. The semi-closed irrigation system, therefore, was determined to be the least-cost tomato irrigation system under present fuel cost and nonlimiting water supply conditions.

A cana-de-açúcar foi plantada no dia 03/03/2000 e a partir de 01/04/2000 iniciaram os tratamentos nas parcelas irrigadas. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos, e quatro repetições, definidos por regimes de freqüência da irrigação. O sistema de irrigação era acionado quando a evapotranspiração da cultura atingisse 10 mm, 20 mm, e 30 mm, para os tratamentos 1, 2, e 3 respectivamente. O tratamento 4 foi definido como testemunha (não irrigado).             A colheita foi realizada no dia 05/12/2000 e através da avaliação de produção de massa fresca, diâmetro e comprimento do colmo, e produção de massa seca, observou-se que não houve diferença estatística entre os diferentes regimes de freqüência de irrigação. Todavia, quando comparado com a testemunha, as irrigações proporcionaram um aumento médio maior que 45 % na produção de massa fresca e seca final dos colmos.   UNITERMOS: irrigação por gotejamento subsuperficial, cana-de-açúcar.   DALRI, A.B., CRUZ, R.L. EFFECT OF SUBSURFACE DRIP IRRIGATION FREQUENCY ON GROWTH OF SUGARCANE (Saccharum spp.)   2 ABSTRACT             The aim of this study was to verify subsurface drip irrigation effects on sugarcane initial growth.           Drip lines were set up under crop rows at 0.3 m deep. Sugarcane was planted on March 3, 2000, and drip irrigation treatments began on April 1, 2000. The experimental design was entirely randomized with four treatments and four replications according  to irrigation frequency. Irrigation system was turned on when crop evapotranspiration reached 10, 20 and 30 mm for the treatments 1, 2 and 3, respectively. Treatment 4 was considered  the control (without irrigation).           Harvest was carried out on December 5, 2000, and based on fresh and dry weight, stem diameter and length evaluation no statistical differences for irrigation frequencies have been observed, although irrigation has increased fresh and dried yield over 45% when compared to the control treatment.  KEYWORDS: subsurface drip irrigation, sugarcane.[1] Parte da dissertação do primeiro autor, para obtenção do título de Mestre em Agronomia – Irrigação e Drenagem

This article presents a description of the design, development, and implementation of web-based software and dedicated hardware which allows for the remote monitoring and control of a drip irrigation system. The hardware consists of in-field stations which are strategically distributed in the field and equipped with different sensors and communication devices; a weather station and drip irrigation system complete the setup. The web-based software makes it possible to remotely access and process the information gathered by all the stations and the irrigation controller. The proposed system was implemented in a young olive orchard, located in the province of San Juan, an arid region of Argentina. The system was installed and evaluated during the seasons 2014–2015 and 2015–2016. Four regulated irrigation strategies were proposed in the olive orchard to test its behavior. In this pilot experiment, the precision irrigation system was a useful tool for precisely managing the irrigation process, applying only the required amount of water (precise irrigation). Regulated deficit irrigation experiments, on the other hand, have demonstrated the sensitivity of olives to water restriction. The precision irrigation system made it possible to control soil moisture levels, avoiding water stress in the control treatment.

Pyrenochaeta Terrestris

The producers areas of onion in Mexico, are affected by the existence and increment of pathogens organisms of the soil like the fungus Pyrenochaeta terrestris, This problem increased its presence and damages due to the consecutive establishment of this vegetable year with year on the same soils. The fungus is activated and this disease developed when the soil temperature is increased. The disease infection of the plants causes rot and death of roots and small bulbs whit no commercial value, and low yields. According that the objective of the present research was to evaluate three treatments for the control of this organism pathogen: The experiment was carried out on INIFAP-CIRNO Experimental Station on a severally infested soil whit this fungus. The sow date was on 6 Jan. 2002, in this trial we used “local” variety. The treatments evaluated were Trichoderma (30 L·ha-1), Humega 8% (180 L·ha-1), Isofert 25 (400 L·ha-1) and a control (without treatment). The products were applied using the drip irrigation system. The results indicate that the treatments with Trichoderma and Humega 8% presented the lower percent of disease roots with 33% and those of more incidence were the control and Isofert 25 with 46% and 47% of disease roots, respectively. The results show 13% efficiency with the use of Trichoderma with respect to control; however this treatment did not affect the bulb weight and yield, control treatment obtained the greatest bulb weight and yield with 212 g for bulb and 80.9 t·ha-1 against 196 g and 71.9 t·ha-1, respectively, of the Trichoderma, which was seemingly a secondary negative effect in decrement the yield.
