Durum wheat is often cultivated in marginal areas with great management difficulties. Organic fertilization a sustainable agricultural practice that allows preserving the environment, but its limit can be reduction of yield and quality crops, also cereals. The aim research was to evaluate effects organic on Simeto, variety durum wheat, for two years three different sites internal hill Campania ...

Adding organic matter to soil proved an efficient strategy for restoring fertility and improving crop dry – indicator of yield potential. In this regard, evaluating the sources (OM) (control, poultry manure [PM], farmyard [FYM], compost, mungbean residues [MR]) provide 120 kg N ha-1 effective microbes (EM) (0, 100, 200, 300 L ton-1 OM) as 2% solution proceeded in field conditions during 2017–20...

Similar to the chaos game representation (CGR) of DNA sequences proposed by Jeffrey (Nucleic Acid Res. 18 (1990) 2163), a new CGR of protein sequences based on the detailed HP model is proposed. Multifractal and correlation analyses of the measures based on the CGR of protein sequences from complete genomes are performed. The Dq spectra of all organisms studied are multifractal-like and suffici...

saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...

Given a matrix A ∈ Rm×n of rank r, and an integer k < r, the top k singular vectors provide the best rank-k approximation to A. When the columns of A have specific meaning, it is desirable to find (provably) “good” approximations to Ak which use only a small number of columns in A. Proposed solutions to this problem have thus far focused on randomized algorithms. Our main result is a simple gre...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...
