In irrigation scheduling, one question is “how much is the optimal depth?”. In this study the optimal irrigation depth (by assuming the power distribution function and by taking into consideration the distribution function, which governs the data (normal distribution)) by considering the environmental effects was determined for three water management strategies (i. e. unlimited, limited nitroge...

to illustrate the impact of various levels of deficit irrigation on yield and yield components of maize cultivars, a study was conducted based on randomized complete blocks as a split plot design with 3 replicates and two treatments for three crop seasons. four levels of deficit irrigation including: conventional, 100, 80, and 60% of water level use were considered as main plots and two varieti...

In order to evaluate the symbiotic effects of mycorrhiza-like fungi, Piriformospora indica (Pi), and mycorrhiza fungi, Glomus mosseae (Gm), on improving the chlorophyll pigments and chlorophyll fluorescence indices of maize (Zea mays L. cv. 'SC 704') under different levels of irrigation and triple super phosphate (TSP), a field experiment was conducted in a split factorial arrengment based on a...

Irrigation water Scarcity is the major limiting factor for crop production in irrigated farming. Therefore, optimal use of water is influenced by seasonal rainfall especially where the water price is high. Nitrogen also plays a key role in plant nutrition. In this study, wheat grain yield production as a function of applied water (irrigation plus seasonal rainfall) and nitrogen fertilizer (appl...

The great challenge of the agricultural sector is to produce more food and/or more revenue from less water, which can be achieved by optimal irrigation management. A task of primary importance is the problem of intraseasonal irrigation scheduling under limited seasonal water supply. On the intraseasonal level, a limited amount of water is to be distributed over a number of irrigations, taking i...

BACKGROUND Open irrigation and débridement is the standard of treatment for septic arthritis of the wrist. Although isolated cases of arthroscopic irrigation and débridement have been reported, a comparison of arthroscopic and open techniques has not been performed, to our knowledge. The purpose of this study was to compare the two methods of management. METHODS A retrospective comparison of ...

OBJECTIVE Hemorrhagic cystitis is a challenging clinical entity with limited evidence available to guide treatment. The use of intravesical silver nitrate has been reported, though supporting literature is sparse. Here, we sought to assess outcomes of patients treated with intravesical silver nitrate for refractory hemorrhagic cystitis. MATERIAL AND METHODS We identified nine patients with re...
