Research ArticleOpen accessPhrase in the titleAssessment of Soil Compaction under Center Pivot Irrigation Systems and its Effect on Crop PerformanceKhalid Ali Al-GaadiA field study on two 12.5 ha plots cultivated with wheat and alfalfa was conducted to determine Soil Compaction (SC), its spatial variability and its effect on crop performance under center pivot irrigation systems. Considering compaction at two tested soil depths, results revealed that the soil of the alfalfa plot exhibited significantly (p<0.01 and p<0.05 for 0 to 10 cm … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 12 Mar 2013 · 7,721 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffect of Plant Density on Flowering Date, Yield and Quality Attribute of Bush Beans (Phaseolus Vulgaris L.) under Center Pivot Irrigation SystemSamih AbubakerThis research evaluates six different planting densities (10∗30, 20∗30, 30∗30, 40∗30, 50∗30, 60∗30) of bean (Phaseolus Vulgaris L.), Bronco variety and their impacts on yield, earliness and quality attributes using Randomized Complete Block Design (RCBD) under central pivot irrigation system in the southern part of Jordan during 2007 growing season. Although, the highest planting density (10∗30 cm) gave the highest … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractIN-SEASON ASSESSMENT OF WHEAT CROP HEALTH USING VEGETATION INDICES BASED ON GROUND MEASURED HYPER SPECTRAL DATAKhalid Ali Al-Gaadi, Virupakshagouda Patil, ElKamil Tola et al.An experiment on a 50 ha center pivot field was conducted to determine the Vegetation Indices (VI’s) that were helpful in assessing the in-season performance of wheat crop treated with graded levels of irrigation water and fertilizers. The irrigation levels were at 100, 90, 80 and 70% evapotranspiration (ETc); however, the fertilizer levels of N: P: K kg-1ha included 300:150:200 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,521 accessesView PDFCite
