An appropriate fertilization strategy is essential for improving micronutrient supply, crop nutrition, yield and quality. Comparative effects of different application strategies fertilizer were evaluated in two contrasting sites/soils (upper slope Chernozem lower Solonetz) within a farm field located the Brown soil zone Saskatchewan, Canada. The study objective was to examine impact Cu, Zn, B o...

this research carried out in the rafsanjan pistachio orchard to investigate the effect of n form, manure, k and fe on yield, nut quality and leaf mineral nutrients concentrations of pistacia vera l. cv. fandoghi grafted on badami-riz zarand rootstock. the experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), n form (ammonium sulfate and ...

We investigate the Zagreb index, one of the topological indices, of random recursive trees in this paper. Through a recurrence equation, the first two moments of Zn, the Zagreb index of a random recursive tree of size n, are obtained. We also show that the random process {Zn − E[Zn], n ≥ 1} is a martingale. Then the asymptotic normality of the Zagreb index of a random recursive tree is given by...

sunflower (helianthus annus l.) is the most important between oil plants in iran. the objective of this study was to evaluate the effects of micronutrients application on the sunflower yield under drought stress. this experiment was carried out at golmakan agriculture research station (iran) in 2005 that using a split plot randomized complete block design with four replications. irrigation was ...

Broadcast is an important application in wireless networks, e.g. for video streaming, file distribution, or event notification. Wireless nodes are battery powered, their network lifetime depends on the energy consumption. Thus, energy efficiency is an important metric when designing broadcast protocols in infrastructureless and all-wireless networks. In this paper, we apply game theory to solve...

We present multicast extensions to our recently proposed Location Prediction Based Routing (LPBR) protocol, referred to as NR-MLPBR and R-MLPBR, to simultaneously reduce the number of multicast tree discoveries and number of links per tree and/or the hop count per source-receiver path in mobile ad hoc networks (MANETs). Nodes running NR-MLPBR are not aware of the receivers of the multicast grou...

the higher levels of essential elements in soil may be caused in optimum yields and crop quality. so it seems to be necessary to examine different levels of nutrients like fe and zn on plants and their productivity. to evaluate effects of iron and zinc application on yield and yield components of pimpinella anisum an experiment was conducted at the research farm of urmia university in 2009. tre...

This paper deals with simulation of the broadcast authentication protocols using Colored Petri Nets and further optimizations in Matlab environment. Typical application of broadcast authentication protocols can be configurations where only one transmitter with multiple recipients exists (such as message exchange in sensor networks routing protocols, or the leader election process in sensors net...
