Entretanto, muitas vezes a irrigação está presente nas agriculturas tecnificadas, pois se traduz em maiores produtividades, melhor qualidade do produto e independência de chuva. Este trabalho teve como objetivo o estudo da freqüência de irrigação por gotejamento subsuperficial no desenvolvimento da cana-de-açúcar, no primeiro ciclo de cultivo. Os tratamentos foram definidos pela freqüência da irrigação: o sistema de irrigação era acionado quando a evapotranspiração da cultura superasse 10 mm, 20 mme 30 mm, para os tratamentos L1, L2 e L3, respectivamente. O tratamento L0 foi definido como testemunha (não irrigado). A irrigação por gotejamento subsuperficial não alterou a qualidade da cana-de-açúcar e não houve diferença estatística entre as diferentes freqüências de irrigação, para produtividade. Todavia, comparados à testemunha, os tratamentos L1, L2 e L3 proporcionaram incremento de produtividade de 47,33%, 58,53%, e 39,86%, respectivamente. UNITERMOS: freqüência de irrigação, manejo de irrigação, análise tecnológica.  DALRI, A. B.; DUENHAS, L. H.; GARCIA, C. J. B.; CRUZ, R. L. SUBSURFACE DRIP IRRIGATION ON SUGARCANE YIELD AND QUALITY   2 ABSTRACT             In Brazil, sugarcane is mostly cropped in dry land conditions. However, it is known that irrigation is present in advanced agriculture, because of its higher yields, better product quality and rainfall independence. This work aimed to study subsurface drip irrigation frequencies on sugarcane development during the first season. Treatments were defined by different irrigation frequencies: irrigation system were turned on when evapotranspiration reached 10 mm, 20 mm, and 30 mm, for treatments L1, L2, and L3, respectively. Treatment L0 was defined as control (non-irrigated). It was observed that subsurface drip irrigation did not affected sugarcane quality and there was no statistical difference among different irrigation frequencies for yield. However, when compared to the control, treatments L1, L2 and L3 showed yield increase of 47.33%, 58.53%, and 39.86%, respectively.KEY WORDS: irrigation frequency, irrigation management, technological analysis.

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

ABSTRACT The present study aimed to evaluate the development, yield and quality of four sugarcane cultivars fertigated by subsurface drip system. The experiment was carried out in Campinas-SP, Brazil, from January 2012 to November 2013, with the cultivars SP79-1011, IACSP94-2101, IACSP94-2094 and IACSP95-5000 subjected to daily irrigations. The irrigations depths were applied to bring soil moisture to field capacity. Soil moisture was monitored using soil moisture probes. Samples were collected along the crop cycle in order to evaluate crop development and yield, at the end of the first and second ratoons. Stalk height showed good correlation for the estimation of crop yield, with R2 equal to or higher than 0.96. The cultivar IACSP95-5000 showed the highest yield in the first ratoon. In the second ratoon the highest yield was observed in IACSP94-2101, followed by IACSP95-5000 and SP79-1011. Considering the yield results associated with the technological analysis, such as soluble solids content and apparent sucrose, the cultivar IACSP95-5000 excelled the others in the cultivation under subsurface drip irrigation.

Soil wetted pattern from a subsurface drip plays great importance in the design of subsurface drip irrigation (SDI) system for delivering the required water directly to the roots of the plant. An equation to estimate the dimensions of the wetted area in soil are taking into account water uptake by roots is simulated numerically using HYDRUS (2D/3D) software. In this paper, three soil textures namely loamy sand, sandy loam, and loam soil were used with three different types of crops tomato, pepper, and cucumber, respectively, and different values of drip discharge, drip depth, and initial soil moisture content were proposed. The soil wetting patterns were obtained at every thirty minutes for a total time of irrigation equal to three hours. Equations for wetted width and depth were predicted and evaluated by utilizing the statistical parameters (model efficiency (EF), and root mean square error (RMSE)). The model efficiency was more than 95%, and RMSE did not exceed 0.64 cm for three soils. This shows that evolved formula can be utilized to describe the soil wetting pattern from SDI system with good accuracy.

This study was conducted to evaluate the surface and subsurface drip irrigation (SDI) application effects on sugar beet crop performance, under two levels (100% and 80%) of water application depth. The experimental design was a split plot with four replications. Laterals were set every second crop row (1 m apart), with emitters spaced 1 m apart. In the case of SDI, laterals were buried 0.45 m under the ground. Soil moisture measurements were taken up to 75 cm depth, using the TDR method. The soil water content and the yield characteristics of each treatment were recorded. Irrigation method showed to affect crop performance significantly while water application level was less critical. The experimental results indicated that the subsurface drip irrigation leaded to a greater yield and higher sugar content making significant water saving compared to surface drip irrigation.

Subsurface Drip

In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high water tables are one of the most inefficient methods of irrigation, though some irrigation management practices can contribute to better soil moisture uniformity. Subsurface drip irrigation systems apply water below the soil surface by microirrigation, improving the water distribution and time required to raise the water table for seepage irrigation.
