J. Econ. Enlomol. 72: 599-601 (1979) Time of tuber infestation by Phthorimaea operculeLla (Zeller) was markedly affected by the type of irrigation system employed. Tuber infestation under furrow irrigation was above 25% for 4 wk prior to vine senescence while sprinkler irrigated potatoes sustained less than 5% damage during this period. After irrigation was terminated, infestation increased rap...

This study was aimed to investigate the effect of surface sprinkler and drip irrigation systems using a model AquaCrop, intervals, bio-organic fertilizers polymers in desert soils. Two field experiments were conducted during spring season 2020 at Karbala governorate. The experiment included three factors: 1-Irrigation system T1 T2, 2- Irrigation interval: every 2 days I1, 4 I2 6 I3, 3- Addition...

ABSTRACT DMulching contributes to the maintenance of soil moisture at reasonable levels for crop growth. It influences water demand and irrigation time. The aim this study was estimate evapotranspiration root uptake by ‘BRS Princesa’ banana cultivar through a simple approach using some components balance within zone in bare mulched irrigated drip micro sprinkler systems. experimental design com...

Soil and water resources can be severely degraded by salinity when total salt input exceeds output in irrigated agriculture. This study was conducted to examine partitioning of Ca2+, Na+, and Cl- between soil and soybean [Glycine max (L.) Merr.] plants under different irrigation regimes with both field and modeling assessments. In drip and sprinkler treatments, the irrigation water was salinize...

We present here the design and fabrication of a self-powered and autonomous fringing field capacitive sensor to measure soil water content. The sensor is manufactured using a conventional printed circuit board and includes a porous ceramic. To read the sensor, we use a circuit that includes a 10 kHz triangle wave generator, an AC amplifier, a precision rectifier and a microcontroller. In terms ...
