1. AGRONOMIC PERFORMANCE OF RADISH GENOTYPES UNDER DIFFERENT IRRIGATION DEPTHS
ABSTRACT In radish production, the choice of proper genotypes and irrigation regime is of great importance to achieve success. In light of this, the current study aimed to evaluate the agronomic performance of a few radish genotypes under different irrigation strategies. The plants were grown in the city of Unaí - MG, in Brazil, under field conditions, and

2. GAS EXCHANGE IN ‘POME’ BANANA PLANTS GROWN UNDER DIFFERENT IRRIGATION SYSTEMS
Abstract This study aimed to evaluate Pome type bananas grown under different irrigation systems. Seventy-two treatments were used in a factorial 3×2×12 scheme, where factors consisted of three irrigation systems (under-tree sprinkling, micro-sprinkling, and dripping), two cultivars (‘Prata-Anã‘ and ‘BRS Platina’), and twelve evaluation periods (m

3. METHODOLOGY FOR DIMENSIONING OF A CENTER PIVOT IRRIGATION SYSTEM OPERATING WITH DRIPPER TYPE EMITTER
ABSTRACT: In Brazil, the conventional center pivot is widely used for irrigation of agricultural crops and its use has grown continuously. However, when improperly managed, it facilitates the development of diseases in all parts of the plant, with a direct effect on productivity, besides favoring losses of water by evaporation. The drip may be an alternative

4. CALCIUM NITRATE CONCENTRATIONS IN FERTIGATION FOR ‘TERRA’ BANANA PRODUCTION
ABSTRACT The aim of this study was to evaluate the effect of calcium nitrate concentration of irrigation water on soil chemical attributes and productivity during the first ‘Terra’ banana crop cycle. The experiment followed a completely randomized design with six treatments and five replications, with six plants per plot. Treatments consisted in the use

5. Effect of hydraulic head in the uniformity of irrigation and fertigation under drip system / Efeito da carga hidrÃulica na uniformidade da irrigaÃÃo e fertirrigaÃÃo em sistema de gotejamento
The irrigation tracked by gravity is a technique applied by the family farming that has been spread in Brazil and is used in social programs of some States or directly traded to producers. Irrigation systems have simplified management and let it cheaper. They intensify agricultural yield, increase the prospects of life in the countryside and, therefore, sett

6. Ecophysiological responses of the winegrape Chenin Blanc under different irrigation management in the São Francisco river valley.
The So Francisco Valley has been considered a new growing region for wine grapeproduction. In this region, the wines have a typical taste and are the unique ones producedunder tropical conditions. Because the irrigation management is one of the most importantfactors related to grape and wine quality, a study was carried out by the Embrapa Semirido,in the VIN

7. Efeitos da irrigaÃÃo com esgoto tratado sobre o sistema solo-planta (milho) e induÃÃo da supressividade a doenÃas causadas por nematÃides / Effects of irrigation with treated sewage on soil â plant(maize) system and inducement of suppressiveness to diseases caused by nematodes
The treated effluents have great potential for application in agriculture, due to certain levels of nutrients and organic material that can improvement the chemical characteristics of soils and thus induce suppressiveness of soils to plant diseases caused by phytopathogens. The objective this word was to provide technical subsidies for the fertirrigation of

8. Levels of irrigation and potassium doses applied by drip irrigation in cultivation of banana for the region at the Apodi plateau-CE / Níveis de irrigação e doses de potássio aplicados por gotejamento na cultura da bananeira para a região da Chapada do Apodi-CE
The region at the Apodi plateau in northeastern Ceará, has been increasing in recent years as a major pole production and marketing of tropical fruits of the state and also in northeastern Brasil, especially as regards the banana plant irrigated agribusiness. In this region the Prata anã varieties, Pacovan and rata Graúda (Pacovan Apodi) are the most plan

9. âANÃLISE TÃCNICA E ECONÃMICA DA PRODUÃÃO DE ALFACE AMERICANA IRRIGAÃÃO POR GOTEJAMENTOâ. / Technical and economical analysis for the crisphead lettuce production under dripping.
Lettuce is one of the vegetables mostly consumed by the Brazilian population, being the states of SÃo Paulo and Minas Gerais the main producers and consumers. With the aim of reducing the difficulties faced by the producers on cultivating the crisphead lettuce, specifically those related to the lack of technical information about the right time to irrigate

10. Desempenho de sistema de irrigação por gotejamento utilizado na aplicação de água residuária de suinocultura / Performance of dripping irrigation system using swine wastewater
The objective of this work was to analyze the performance of a drip irrigation system using swine wastewater. The following parameters were evaluated: (a) removal of suspended solids, oils and greases by passing the effluent through sloped static screens; (b) influence of service pressure on clogging of drippers operating with effluent and water; and (c) eff

11. Effects of treated sewage effluent irrigation on the soil-plant system of an Oxisol cultivated with sugarcane / Efeito da irrigação com efluente de esgoto tratado no sistema solo-planta em Latossolo cultivado com cana-de-açúcar
O uso de efluente de esgoto tratado (EET) na agricultura apresenta-se como uma alternativa viável por se tratar de uma fonte de umidade e de nutrientes minerais aos sistemas agrícolas, aliado à redução da utilização de água de boa qualidade na irrigação, bem como a diminuição da descarga do EET nos rios, minimizando assim possíveis danos ambient
