O experimento foi conduzido na Unidade de Pesquisa Hélio de Moraes, do IAC, no município de Jaú, SP, (22°17’ S 48°34’ O, em Latossolo Vermelho). A variedade de cana-de-açúcar foi a RB92579. O delineamento experimental foi em blocos casualizados, composto por fatorial de 2 manejos de irrigação: irrigado (I) e não irrigado (NI), 2 manejos de inoculação: com inoculação (Inoc) e sem inoculação (Não inoc) com bactérias diazotróficas (BDs); e com 4 níveis de disponibilidade de nitrogênio (0, 70, 140 e 210 kg ha-1 de N), compondo assim 16 tratamentos com 4 repetições. O experimento teve duração de 365 dias, quando então foram realizadas as análises tecnológicas e determinou-se a produtividade de colmos (TCH) e de açúcar (TPH). A cana-de-açúcar elevou sua produtividade com a elevação das doses de nitrogênio. Nos tratamentos irrigados essa elevação foi maior comparando-se com os tratamentos não irrigados.

SUGARCANE YIELD FERTIGATION MANAGEMENT WITH DOSES OF N AND INOCULATED WITH DIAZOTROPHIC BACTERIA 2 ABSTRACT The objective of this study was to evaluate the efficiency of inoculation with diazotrophic bacteria and nitrogen fertilization on yield and technological quality of sugarcane (cane plant), in the following managements: irrigated by subsurface drip and rainfed. The experiment was conducted at Hélio de Moraes Research Unit, of IAC in the municipality of Jaú, SP, (22 ° 17 'S 48 ° 34' O, Rhodic). The variety of sugarcane was RB92579. The experimental design was randomized blocks, composed by factorial of two irrigation management systems: irrigated (I) and non-irrigated (NI); and two-inoculation managements: with inoculation (Inoc) and without inoculation (No inoc) with diazotrophic bacterias (BDs); and 4 availability levels of nitrogen (0, 70, 140 and 210 kg ha-1 de N), thus forming 16 treatments with 4 replications. The experiment lasted 365 days when then technological analysis was performed and determined sugarcane stalk yield (TCH) and sugar yield (TPH). The sugarcane raised its productivity with rising nitrogen levels. In irrigated treatments this increase was higher compared with non-irrigated treatments. Keywords: Saccharum spp., subsurface drip, nitrogen fertilization, nitrogen biological fixation.

Subsurface Drip

The temporal and spatial dynamics of Sclerotinia minor sclerotia and the resulting incidence of lettuce drop were studied under furrow irrigation with conventional tillage and subsurface-drip irrigation with minimum tillage during 1993–95. Lettuce crops were grown each year during the spring and fall seasons. All plants were inoculated immediately after thinning in the spring of 1993. Grids of 24 contiguous quadrats (1 by 1 m2) were demarcated in the centers of each 150-m2 plot. Lettuce drop incidence in each quadrat was evaluated each season prior to harvest. One soil sample (100 cm3) was collected from each quadrat at harvest and after tillage prior to planting of the next crop for both spring and fall crops and assayed for S. minor sclerotia using wet sieving. Lloyd's index of patchiness, the β-binomial distribution, and variance of moving window averages were used to evaluate the spatial patterns of sclerotia and lettuce drop incidence under the two irrigation systems and associated tillage treatments. Disease incidence remained significantly higher under furrow irrigation than under subsurface-drip irrigation throughout the study period, and was significantly higher on fall crops than on spring crops. Under furrow irrigation, the number of sclerotia at the end of a crop season increased significantly over that at the beginning of the season, but no significant changes were detected over years. In contrast, the number of sclerotia within a single season did not increase significantly under subsurface drip irrigation, nor was year-to-year accumulation of sclerotia statistically significant. The degree of aggregation of sclerotia increased significantly during a cropping season under furrow irrigation, but not under subsurface drip irrigation. The conventional tillage after harvest under furrow irrigation decreased the degree of aggregation of sclerotia after each season, but the distribution pattern of sclerotia under subsurface-drip irrigation changed little by the associated minimum tillage. Spatial pattern analyses suggested that the aggregation of S. minor sclerotia occurred at a scale of no more than 1 m, and distribution of diseased lettuce plants was random at a scale larger than 1 m. The combination of fewer sclerotia produced by each crop and its unaltered distribution under subsurface drip irrigation and associated minimum tillage makes it a valuable cultural practice for lettuce drop management.

Semi Arid

Two different irrigation systems, subsurface drip irrigation and furrow irrigation, are tested to investigate the level of viral contamination and survival when tertiary effluent is used in arid and semi-arid regions. The effluent was injected with bacteriophages of PRD1 and MS2. A greater number of PRD1 and MS2 were recovered from the lettuce in the subsurface drip-irrigated plots as compared to those in the furrow-irrigated plots. Shallow drip tape installation and preferential water paths through cracks on the soil surface appeared to be the main causes of high viral contamination in subsurface drip irrigation plots, which led to the direct contact of the lettuce stems with the irrigation water which penetrated the soil surface. The water use efficiency of the subsurface drip irrigation system was higher than that of the furrow irrigation system. Thus, subsurface drip irrigation is an efficient irrigation method for vegetable crops in arid and semi-arid regions if viral contamination can be reduced. Deeper installation of drip tapes, frequent irrigations, and timely harvests based on cumulative heat units may further reduce health risks by ensuring viral die-off under various field conditions.

Selection of the proper irrigation method will be advantageous to manage limited water supplies and increase crop profitability. The overall objective of this study was to evaluate the effect of subsurface drip irrigation (SDI) and furrow irrigation on onion yield and irrigation use efficiency. This study was conducted in two locations, a commercial field and a field located at the Texas A&M AgriLife Research Center in Weslaco, TX. This study was conducted as a split-plot design for both sites with two treatments (SDI and furrow irrigation) and three replications per treatment. The total onion yield obtained with the SDI systems was more than 93% higher than the yield obtained with furrow irrigation systems. The large onion size was 181% higher for the SDI system than the furrow system in both sites. The colossal size yield was also higher. At one site colossal yield was 206% higher than furrow, while at another site furrow yielded no colossal onions and SDI had some production. It was concluded that drip irrigation systems more than double yields and increased onion size while using almost half of the water. This was due to SDI allowing for more frequent and smaller irrigation depths with higher irrigation efficiency than furrow irrigation systems.

Tail Water

The practice and management of subsurface drip irrigation (SDI) on heavy clay soils is poorly understood. Over-irrigation can lead to excessive runoff and drainage, with associated negative environmental consequences. Experiments were conducted in 2001/2002 and 2002/2003 on cotton (Gossypium hirsutum) in a Vertisol in Australia to evaluate the effect of SDI at various application rates on cotton yield and quality, and the results were compared with those for conventional furrow irrigation. Irrigating with SDI that supplied 50% or 75% of daily crop evapotranspiration (ETc) maintained a dry upper soil profile throughout the season. SDI at 50% ETc could potentially capture 250mm more rain during the season compared to SDI 90% ETc, and even more than furrow irrigation. However, supplying only 50% ETc with SDI hastened the maturity of the crop by on average 25 days compared with furrow irrigation and higher SDI rates, fewer bolls were set and yields were lower than in the other treatments. Nevertheless, a shorter season, if yield sacrifice is acceptable, favours logistics when integrating winter crops with summer cotton. It also reduces the number and cost of pesticide sprays and irrigation. Yield plateaued when 75% or more of daily ETc was supplied by SDI. The two drier treatments (SDI at 50% and 75% of ETc) had consistently higher water use efficiencies (WUE) for lint production compared with those of the two wetter SDI treatments (SDI at 90% and 105/120% ETc). All SDI treatments were also more efficient in the first year in the use of water for lint production than was furrow irrigation, but improved irrigation management in the form of faster irrigation and reduction of tail water in the second year obviated the advantage of SDI. Irrigation of cotton with SDI at 75% ETc offered significant benefits in terms of saved irrigation water over wetter SDI treatments, resulted in the highest average WUE for lint production over the two years, and reduced drainage and runoff compared with higher SDI rates and furrow irrigation.
