A field experiment was carried out to investigate the effects of varying nitrogen (N) supply andirrigation methods on the root growth and distribution of maize (Zea mays L.) in Wuwei,northwest China in 2011 and 2012. The irrigation treatments included alternate furrow irrigation(AI), fixed furrow irrigation (FI) and conventional furrow irrigation (CI). The N supply treatmentsincluded alternate ...

This paper investigates the reliability characteristics of a complex system having nine subsystems arranged in the form of 3x3 matrix in which each row contains three subsystems. The configuration of the row is of the type 2-out-of-3: F. Each subsystem has n units connected in series. The system fails if any one row containing three subsystems fails. The considered system analyzed incorporating...

The effects of periodicity perturbations in underwater phononic crystal layers composed of noninterpenetrating rows of identical shells are investigated. The results for one row are obtained by using a multiple scattering method between shells. Then, taking into account the multiple reflections and transmissions between two adjacent rows, a Debye series method is used to calculate the reflectio...

introduction evaluating yield in intercropping systems is based on selecting compatible plants with appropriate characteristics to establish minimum competition and maximum cooperation, and the application of suitable agricultural practices (crop density and intercropping ratio). the use of plant species with different morphological characteristics in terms of nutrient uptake and utilization of...

A two year field experiment was carried out to evaluate the effects of three row and eight row seeding on the total phenolic compound (TPC), total flavonoid content (TFC), hydrolyzed (HTC) and condensed tannin (CTC), antioxidant activity (ABTS assay), protein content and soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) in the extracts of lentil (Lens culinaris L.) and grass pea (La...

BACKGROUND Arthroscopic rotator cuff repair is a common procedure that is gaining wide acceptance among orthopaedic surgeons because it is less invasive than open repair techniques. However, there is little consensus on whether to employ single-row or double-row fixation. The purpose of the present study was to systematically review the English-language literature to see if there is a differenc...

This research was conducted to determine the effects of different row spacings and sowing rates on hay quality characteristics under Tokat-Kazova ecological conditions during years 2014-2016. In study, cultivars alfalfa Bilensoy-80 sown at four (15, 30, 45 60 cm) six (5, 10, 15, 20, 25 30 kg ha-1) The experimental design completely randomized in split plots with replications. Main were sub-plot...
