An experiment was conducted to evaluate the effect of various levels of phosphorus fertilizer on the yield and nutritional value of sorghum fodder at three cuttings. The experiment was conducted by using 4 levels of Phosphorus fertilizer viz. 0 (T0) 40 (T1), 80 (T2) and 120 (T3) kg TSP/ha in a Completely Randomized Design (CRD). A significant effect (P<0.01) of phosphorus fertilizer application...
In order to investigate the cumulative effect of three-year application of municipal solid waste compost (C) and the compost accompanied with chemical fertilizer (CF) on the concentrations of some heavy metals in various organs of rice plant, a field experiment with completely randomized design in three replications was performed in 2009. Treatments were as follows: Control (without C and CF), ...
An experiment was carried out during two subsequent years, i.e., 2009-10 and 2010-11 to study the influence of Azotobacter, vermicompost on growth, flowering, yield and quality of strawberry cv. Chandler. There were nine treatments comprising two levels each of Azotobacter (6 and 7 kg/ha) and vermicompost (20 and 30 t/ ha) and their combinations along with one control, replicated thrice in rand...
proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...
In laboratory, greenhouse and field tests, we determined the effects of combining full rates of the defoliants tribufos and thidiazuron and the herbicide thifensulfuron-methyl with half rates of the insecticides lambda-cyhalothrin or azinphos-methyl, and the combination of tribufos and thidiazuron, both in half rates, on mortality of the boll weevil, Anthonomus grandis grandis Boheman and on th...
Serum bactericidal activity against 20 strains of Pseudomonas aeruginosa was studied in 10 volunteers after administration of imipenem (25 mg/kg), imipenem (25 mg/kg) plus amikacin (7.5 mg/kg), and ceftazidime (25 mg/kg) plus amikacin (7.5 mg/kg). Eight strains were susceptible and 12 were resistant to ticarcillin. Serum levels were measured microbiologically after 30 and 60 min and were, respe...
Ecosystem nitrogen (N), phosphorus (P), and calcium (Ca) fluxes are affected by inputs of atmospheric N. Oak litter may additionally affect these fluxes because of its high-lignin content. We analyzed nutrient dynamics in ambient mixed-species litter in an aggrading hardwood stand at the Fernow Experimental Forest in West Virginia. We separated oak from the mix for analysis (oak) and compared i...
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...
this study examined the environmental impacts of irrigated and rainfed barley agroecosystems of iran based on nitrogen levels by using lca methodology during 1999-2013. four steps includung goal definition and scoping, inventory analysis, life cycle impact assessment and integration & interpretation were considered. impact categories were acidification, eutrophication and global warming. functi...
To investigate the effects of arbuscular mycorrhiza (AM) and phosphorus (P) rates on the uptake of primary and secondary nutrients by tomato (Lycopersicon esculentum Milli) cv. BARI Tomato-2 seedlings, under P levels ranging from low to excessive, plants were grown in five levels of P (0, 7.5, 15.0, 22.5 and 30.0 mg P kg-1 soil) as TSP, either inoculated with AM or without AM. The total dry mat...
