1. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

3. Influence of irrigation frequency and nitrogen concentration on Tifway 419 bermudagrass in Brazil
ABSTRACT Tifway 419 Bermudagrass is widely used on athletic fields, requiring irrigation and fertilization for its maintenance; however, little information is available for Bermudagrass management in tropical countries, as Brazil. Thus, this study aimed to evaluate the effect of irrigation frequency and nitrogen (N) fertilization on the development of Tifway

6. Repeated geophysical measurements in dry and wet soil conditions to describe soil water content variability
ABSTRACT: There is an increasing interest in the application of geophysical surveys to assess the soil water content (SWC) variation in both spatial and temporal scales. In this work, a geophysical survey was carried out at an experimental farm in dry and wet conditions. We determined the SWC data measured with the gravimetric method, apparent electrical con

7. Soil-water-plant relationship and fruit yield under partial root-zone drying irrigation on banana crop
ABSTRACT: Climatic uncertainties have compromised water resources, which influences irrigated agriculture. Irrigation is an important alternative to mitigate the effects of water scarcity. Partial root-zone drying (PRD) is a rational use of irrigation water. This study aimed to evaluate PRD for irrigation management of banana crop, cv BRS Princesa, under sem

9. Estudo do manejo da cultura do melÃo submetida à diferentes frequÃncias de irrigaÃÃo e fertirrigaÃÃo com N e P / Research of the melon crop management under different irrigation frequencies and N and P fertigation
O melÃo à a principal olerÃcola exportada pelo estado do CearÃ, sendo uma importante geradora de renda e empregos para a regiÃo. Em contrapartida, os produtores cearenses, alÃm de nÃo receberem muitos incentivos governamentais, enfrentam uma concorrÃncia desleal de produtores internacionais, principalmente espanhÃis e turcos, jà que estes receberem

10. Aplicação da trifluralina no controle da intrusão radicular de tubogotejadores enterrados sob lavoura cafeeira / Application of trifluralin in root intrusion control of subsurface drip under coffee
The objective of this research was to investigate effects of different doses and frequency of application of the herbicide Trifluralin to avoid root intrusion in subsurface drip irrigation in a coffee field during its initial development (6 to 18 months). While the space between rows was 2.5 meters, space between plants was 0.5 meters. A completely randomize

11. Irrigation frequency and substrate volume effects in the growth and yield of tomato plants under greenhouse conditions
Tomato cropping (Solanum lycopersicum L.) under protected cultivation using substrates and drip fertigation has improved sustainable production systems especially fruit quality and plant health. However, little is known for tomato plants when considering the interaction between substrate volume and irrigation frequency. The aim of this study was to evaluate
