The deep placement of urea fertilizer (DMU) containing 1% (W/W) of the nitrification inhibitor 3,4-dimethylpyrazole phosphate\n(DMPP) on soybean growth and seed yield was as effective as those of the coated urea (CU) and lime nitrogen (LN) in a field\nresearch. The average seed yields were high in LN...........
The use of biofertilizers is important for sustainable agriculture, and the use of nodule\nbacteria and endophytic actinomycetes is an attractive way to enhance plant growth and yield.\nThis study tested the effects of a biofertilizer produced from Bradyrhizobium strains and\nStreptomyces griseoflavus on leguminous, cereal, and vegetable crops. Nitrogen fixation was\nmeasured using the acetylene reduction assay. Under N-limited or N-supplemented conditions,\nthe biofertilizer significantly promoted the shoot and root growth of mung bean, cowpea, and\nsoybean compared with the control. Therefore, the biofertilizer used in this study was effective in\nmung bean, cowpea, and soybean regardless of N application. In this study, significant increments\nin plant growth, nodulation, nitrogen fixation, nitrogen, phosphorus, and potassium (NPK)\nuptake, and seed yield were found in mung beans and soybeans. Therefore, Bradyrhizobium\njaponicum SAY3-7 plus Bradyrhizobium elkanii BLY3-8 and Streptomyces griseoflavus are effective\nbacteria that can be used together as biofertilizer for the production of economically important\nleguminous crops, especially soybean and mung bean. The biofertilizer produced from\nBradyrhizobium and S. griseoflavus P4 will be useful for both soybean and mung bean production....
Potato is a starchy, tuberous crop from the perennial Solanum tuberosum having high\nnutritional values. This paper is the first analytical approach to quantify Pt and Rh in vegetal\nfood. In this study a total of 38 different potato samples produced in Europe and one in Australia\nwere investigated. Determinations of Pt and Rh in potato samples were carried out by Differential\npulse voltammetry (DPV/a) for platinum and by Adsorptive stripping voltammetry (AdSV) for Rh\nusing standard addition procedure. Because no certified reference potatoes containing platinum and\nrhodium are available, we used addition standard method.......
Irrigation pumping is a major expense of agricultural operations, especially in arid/semi-arid\nareas that extract large amounts of water from deep groundwater resources. Studying and improving\npumping efficiencies can have direct impacts on farm net profits and on the amount of greenhouse\ngases (GHG) emitted from pumping plants. In this study, the overall pumping efficiency (OPE),\nthe GHG emissions, and the costs of irrigation pumping were investigated for electric pumps extracting\nfrom the Rush Springs (RS) aquifer in central Oklahoma and the natural gas-powered pumps tapping\nthe Ogallala (OG) aquifer in the Oklahoma Panhandle. The results showed that all electric plants and\nthe majority of natural gas plants operated at OPE levels below achievable standard levels. The total\nemission from the plants in the OG region was 49% larger than that from plants in the RS region.\nHowever, the emission per unit irrigated area and unit total dynamic head of pumping was 4% smaller\nfor the natural gas plants in the OG area. A long-term analysis conducted over the 2001â??2017 period\nrevealed that 34% and 19% reductions in energy requirements and 52% and 20% decreases in GHG\nemissions can be achieved if the OPE were improved to achievable standards for plants in the RS and\nOG regions, respectively....
The aim of the study was to assess the impact of sulphur and molybdenum fertilization on the yield and chemical composition of\ncommon bean seeds. A field experiment was conducted in southeastern Poland in 2012â??2014. The scheme of the study included\nthe following treatments: O-control, Mo-molybdenum....................
