to determinate the most proper n.p.k. fertilizer level  for increasing the quality and quantity of polygerm seeds of sugar beet , an experiment was conducted in randomized complete block design with three replications in 1998-2000 at research farm of faculty of agriculture, azad university of ardabil (hassan barog). fertilizer treatments were: n30p60k60, n90p90k90, n0p0k0, n90p150k150, n90p120k...

A study was carried out in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Old Brahmaputra Flood Plains Soil (AEZ-9) during December 2001 to April 2002 to find out the effect of seed rates and NPK levels on dry matter accumulation and grain yield of foxtail millet (Setaria italica L. Beauv.). Four seed rates viz., 8,10,12, and 14 kg/ha and five levels of NPK ferti...

The aim of the present study was to evaluate the growth and macronutrient (C, N, P, K) status in the foliage of four tree species (LT: Liriodendron tulipifera L.; PY: Prunus yedoensis Matsumura; QA: Quercus acutissima Carruth; PT: Pinus thunbergii Parl.) in response to fertilization with different nutrient ratios in a fire-disturbed urban forest located in BongDaesan (Mt.), Korea. Two fertilize...

The studies were carried out in order to identify the responsiveness of five varieties spring wheat variants with applying mineral fertilizers and study specific features formation elements yield structure. work was 2019-2021 on dark gray forest heavy loamy soil Ryazan region. experiment scheme was: N0P0K0 (control); N 64 P K ; + 30 15 . Over years research, varied from 2.45 5.57 t/ha, dependin...

The excessive application of mineral fertilizers in maize cultivation leads to progressive soil contamination the long term and increases cost production. An alternative reduce over-fertilization is perform a partial replacement with microbes that promote nutrition growth, such as Arbuscular Mycorrhizal Fungi (AMF). A pot experiment which was followed by two field experiments performed without ...

The study was conducted between 2020 and 2022 in the experimental field of Maize Research Institute-Knezha. subject is following hybrids: Kn-517 group 500-600 FAO with a density 5500 p/da 6000 p/da; Kn-613 over 600 5200 5700 p/da. cultivated hybrids each variation measured height 10 plants. maize grown under control variant T0 – without fertilization two levels: Т1 N8.5P5.4K6.4 T2 N17P10.8K12.8...

Wheat is one of the most widely distributed crops worldwide and is of primary importance as food for human nutrition. Increasing the productivity of the new wheat varieties according to the specific climate of the region is a permanent major task. The impact of environment and some agronomy practices (previous crop and mineral fertilization) on the productivity and the structural elements of yi...

JA (Jerusalem artichoke) cultivars react differently to mineral fertilization. Hence, the aim of this study was assess effect fertilization on yield and structure species in terms its aboveground biomass. The research based a field experiment carried out 2016–2018 Central Eastern Poland using randomized subblock method, split-split-plot-dependent system. factors first-order were Jerusalem artic...
