Canola sensitivity to delayed sowing date should be managed in such a way that the observance of crop rotation with less reduced in seed yield. The research was conducted to evaluate the yield variation of Hyola401 hybrid, affected by sowing date and nitrogen fertilizer treatments. In this study, the effect of planting date and different levels of nitrogen fertilizers on effective characteristi...

Let k ≥ 3 be a fixed integer and let Zk(G) be the number of k-colourings of the graph G. For certain values of the average degree, the random variable Zk(G(n,m)) is known to be concentrated in the sense that 1 n (lnZk(G(n,m)) − lnE[Zk(G(n,m))]) converges to 0 in probability [Achlioptas and Coja-Oghlan: Proc. FOCS 2008]. In the present paper we prove a significantly stronger concentration result...
