The biofortification of lentil (Lens culinaris Medikus.) has the potential to provide adequate daily selenium (Se) to human diets. The objectives of this study were to (1) determine how low-dose Se fertilizer application at germination affects seedling biomass, antioxidant activity, and Se uptake of 26 cultivated lentil genotypes; and (2) quantify the seed Se concentration of 191 lentil wild ac...
To determine the effect of inorganic N fertilizer on the incidence of yellow stem borer (YSB), Scirpophaga incertulas Walker and on grain yield, yield attributes and bio-chemical characters of local paddy cultivar Tulaipanji, a field experiment for three consecutive years (2007-2009) was carried out by randomized block design in pesticide untreated field. Treatments comprised of seven different...
This study was conducted at the Agricultural Research Station, King Abdulaziz University at Hada El-Sham during 2007 and 2008 seasons to improve the seed yield of sesame (Sesamum indicum L.) in the Makkah Region, Saudi Arabia. Split plot design with four replications was used in this study. Main plot treatments were four nitrogen rates (0, 100, 150 and 200 kg N/ha) and the sub plot treatments w...
In order to maintain sustainable agriculture and prevent excessive use of chemical fertilizers, supplying part of the plant needs by organic fertilizers is necessary. In this respect, effects of nitrogen (N) source and rate on yield and yield components of forage sorghum was evaluated as a factorial experiment arranged in randomized complete blocks design with three replications at the Research...
This study examines the agronomic response, efficiency and profitability of fertilizer microdosing in maize. An experiment with the following treatments was conducted: control without fertilizer, microdosing treatments, with the rate of 27 + 27, 53 + 53 and 80 + 80 kg ha, and banding of fertilizer with 100 + 100 kg ha of di ammonium phosphate (DAP) + urea, applied at planting and jointing, resp...
During 19 years of research on silage maize grown a fertile sandy loam soil in Flanders, we compared the use of only inorganic nitrogen (S−) with a system of an annual application of dairy cattle slurry (S+, corresponding with an average rate of 180 kg N ha−1) supplemented with inorganic fertilizer nitrogen. The objectives were to study the efficiency of slurry-N, to determine the economic opti...
The potential for non-point-source pollution of surface waters from agricultural lands continues to be a concern. Our objective was to determine the effect of surface residue management and fertilizer application timing in regards to soil moisture conditions on nutrient losses in runoff. Studies were conducted using a rainfall simulator that applied 125 mm h-1 for 3 h to an Austin (Udorthentic ...
This study was done to evaluate the effect of different planting arrangements (square, lozenge and rectangular) and various concentrations of potassium sulfate (K2SO4) fertilizer (0, 100, 200 and 300 kg/ha) on yield and essential oils quantitative of Calendula officinalis L., a medicinal and ornamental plant. The experiment was done as a factorial in randomized completely blocks design (R.C.B.D...
to investigate the effects of intercropping of basil (ocimum basiilicum l.) and cowpea (vigna unguiculata l.), different levels of nitrogen fertilizers on basil and cowpea yield, an experiment was carried out during 2010 and 2011. experimental factor were included weed treatment (weeding and unweeding), three levels of nitrogen fertilizer (0, 50 and 100 kg ha-1), different planting ratio, (p1: ...
In order to study the effects of water stress and different amounts of sulfur fertilizer on grain yield, nutrient status and chlorophyll content in black cumin (Nigella sativa L.) a field experiment as split plot design with three replications was conducted at Ghaen city in 2009. Treatments included three levels of irrigation after 50, 100 and 150 mm evaporation from Class A pan as main plot an...
